Hi Rob - I know its a year + since this video - but I do watch them several times - this time I noticed that there is a stainless steel current collector on both sides of each cell. In the previous bipolar plate video (larger acrylic frames) only one current collector was shown per cell - except for the end cells. Can you clarify why the difference? Much thanks - if you're still able to respond to 'an olde but goodie' video. Dennis
Additive printing could make those fast
Beatifull music, i remenber when i was child, thank for you video
PRETTY AWESOME,.... is an understatement. !!!
lol - cheers mate
im wondering if that works.can you try that in the next videos perhapsthanks mate keep up the good work
can you make battery bipolar just like the plates in the electrolytic capacitor with separator between them and will it work
Hey, how's the progress going? I hear the inventor of the lithium ion battery has come up with a design for a solid state li-ion battery. Any thoughts about this? I remember you doing the pva solid electrolyte.
see the latest video mate
This is very interest mate I can't help but wonder what sort of battery/ performance would you end up with if you cut loads of little circles out in the same way and stack as may as you can into say a AA battery? or other cylindrical type of battery C or D type? might be worth a try, just a thought :-)
like a zamboni pile? - interesting idea mate
Nice, I'll take 30 kilowatt hours worth, if they last 40 years and cost $1 per watt hour (or less), delivered to SE QLD Australia, because that is what I recall a large house scale nickel iron battery bank costs from SDS power equipment.Oh and if you can handle a megawatt hour scale order I hear that South Australia are in the market. ;-)
yeah - i over looked that too lol - nice one mate - it shows how I don't think things through.I am pretty sure I can compete - hmmmm
But that is for a 40 year life span, so if lithium lasts 1/10th of that then over the same life span lithium is more like $1.28, then there is the recycling costs on the shorter lived technologies. People often overlook that, like they do the insurance you need on solar PV to cover storm damage risk. Anyway I was giving you a ball park figure for a completed installation ready to plug in. I guess my point is, if you can compete when taking into account all of the relevant variables there is a demand, and it is growing rapidly.
$1 per watt hour is really expensive mate - are you sure you got that right? - Lithium Ion only costs12.8 cents per watt hour and lead acid is only 10 cents per watt hour
Sir can you point out if graphene has any Thermoelectric properties or not
yes it does - there is research on it - look at google scholar
Content and presentation of these videos is top class! Great job Mr. Smith! I am not a specialist in field of electrochemistry but I have a question related to LiFePO4 cell. Is it possible to regenerate such cell by recoating the negative electrode with clean graphite layer? I know that electrolyte for these cells cost 160$ for 1kg but if cost would not be a barrier? When I recently disassembled one of these dead cells I got an impression that it is only negative electrode that gets deteriorated. Correct me please if I am wrong. I am just a hobbyst so I might be completely wrong about that.
Ok once more thank you for checking out this idea!
yeah i suppose i haven't thought about it much until now so let me have a mull over lol
That would be really interesting! Maybe just for the sake of test this expensive electrolyte could be replaced with some cheaper type
I suppose i could give it a go
Thank you for reply. So just to confirm regenerating the negative electrode graphite should be sufficient? Positive electrode layer does not degrade as fast as negative? Maybe graphene coat on negative electrode would be even better? Would you be able to make a video about this process?
Thank you! Brilliant idea.
he hasn't posted a video in two weeks.... something big is coming... lol
Was thinking the same. Maybe Rob's been toying with the various copycats and is skipping phases 1/2/3/4 and launching with phase 5, having already started researching phase 9 that weighs 5kgs and powers a whole house for a fortnight :-). I've a number of applications here that have been shelved until power storage and delivery advanced enough, and then also the usual suspects/candidates for direct replacements with better batteries. Holding off on an off-grid house that needs about $25k worth of currently available generation/storage.
interesting, so you are stacking cells (increasing voltage?) could you glue the cells together with your conductive glue?
Robert your batttery designed no doubt more power storage than Lithium ion, but may I know how it par based from the durability comparison to Lithium from discharge and charge cycle ?
Cheers mate - Interesting stuff you are up too
Thanks for replying and what I can say is ....Rob U r one of the nicest person on internet.
it lasts 1,000 plus cycles mate
Hi, Robert, pls. can you give me the link of the video that you are dicussing about diatoms application and on how to prepare ? Thanks
I don't rememeber tht one mate sorry
In case you haven't seen it yet, Robert: news.utexas.edu/2017/02/28/goodenough-introduces-new-battery-technology
I've seen it - cheers mate
Hi Robert. Can I know where your lab is.? I am planning a visit to UK London Wallingford by Mid March. I will try if we can meet.
we are in canterbury, kent
Robert, what do you think about the "new" way of making graphite in an explosion chamber?
it seems to work
Rob,I just read something so crazy,I thought you'd like to see it...www.sciencedaily.com/releases/2017/02/170227152004.htm
great video robert! i have heard of a new battery/fuel cell type device this would be great for. it uses carbon dioxide/ aluminum/oxygen as the fuel cell reactants. made from baking soda, vinegar, hydrogen peroxide with aluminum and copper electrodes. these bipolar plates would be great for it!
give it a go mate
You definitely deserve more views for your advancements in technology both organic and alternative technologies
well ilike your videos. good job!
I put no effort into advertising the channel mate - i just make the videos and folks find them and watch them - not everyone finds them
google like larry summers has a problem putting science videos in female users feeds. this is a large part of the problem. my own channel has a top of around 10 percent female views.
Did I miss a video where Rob makes the active material? is it the same one used in EESD?
Thanks for the great work Rob
i have done loads of videos on various active materials mate and there are loads of active materials available via google scholar
Your like a scientific rock star sir! Keep it going.
Go go go. Love it all. Robert, have you ever, for no reason whatsoever switched a car battery over to a alum battery? What benefits would it give you think?
Yeah. Just never saw it get done with your level. Its cool. Later.
i've never played with them mate - so i don't really know - lots of info out there though
Can electrolytes used in batteries, also be used in super capacitors? What different purposes do they serve? Based on my garbage understanding of super capacitors, they can't operate on high voltages, because the electrolyte breaks down. Could this Electrolyte www.nature.com/articles/ncomms12032 be used in super capacitors?
Robert, you might be interested in what this guy has done ruclip.com/video/K-PkoJrs5n8/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE.html its some kind of electrically conducting foam. I know how you always want us to try things and such. But I think you might be interested. To increase surface are for energy storage I've been thinking that a dense but thin foam would be great. you can maintain the thickness constant by using glass beads across plates.1) mix beads into your paint
it is interesting mate - but i can't do everything - it's one of the reasons i ty to encourage others to try
Hi Rob, A video that might intrigue, 'Plasma Generator!' ruclip.com/video/eTlA8Ee6b0Q/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE.html
very interesting mate - cheers
i'm very grateful for you. If only our social systems could allow a preponderance of humanity to come forth as is exemplary in your goodness.
Hi Robert. hey, can regular chewing gum also produce graphene from graphite by smearing it on graphite and then stretching it mixing it in? wouldn't the graphite sort of pull away and mix into the gum as the gum gets deformed? So I was thinking if a highly permeated gum would create a good flexible conducting plate or cathode. maybe you don't need that sticky tape, just a gum dispenser making squares from a 3d printer onto your sheets.
no idea mate - sounds interesting though - give it a go and let me know what happens
your a genius bud
Asesommmme! When do you think you might publish test results? Only curious. No rush from me.
as soon as i get them mate - i am still waiting too - i don't want to hassel the guys doing it as they are doing it for free
This is getting into some similar manufacturing processes that i've played around with. What i learned was that craft and scrapbooking hobbies have a LOT of cheap stuff that's useful for this:- Small hand-held paper punches come in various patterns and designs, very cheap, and are in every craft store, toy stores, ebay basically everywhere. You'll be sure to find relevant shapes. They can cut out thin transparency material and foil.- There's relatively cheap USB "Cutting plotters" that are made for cutting paper designs for scrapbooking, they can also cut thin transparency material. A company called "Silhouette" makes a lot of them but there's probably others.- You can also get small die cutting and embossing presses, which press a whole sheet of paper/transparency against a pre-existing stencil/die to form or cut a pattern. They're basically like a very small & cheap printing press. There's various manufacturers of these like "Cuttlebug" and "Big shot", and they're so simple you can generally use any die with any machine.- You can also use common household chemicals to etch patterns/designs from any thin material. But this is getting a bit too complex to explain in a single bullet point (there's just so many ways to do it).
awesome post mate thanks for the pointers
If you offered some sort of short coarse on battery making it would be the best thing since sliced bread. I know that's kind of what you are doing but have you heard of Hugh Piggot? He wrote a book on making wind turbines from scratch and he's been running a coarse in Scoraig, Scotland for years now. If you did a battery one it would be the perfect match.
interesting idea mate - cheers
Good to see your still at it Robert.
Robert, you should put a little bit of tape in the end of the motor then we could see it going round.
ok mate - good point - a spot of white paint?
This may be of interest, soya bean graphene. As always thanks for you videos. phys.org/news/2017-02-team-high-quality-graphene-soybeans.html
read it mate - but thanks for thinking of me
Lasers burning shapes, Raw bipolar battery power production, fast moving propellers, awesome kicking tunes.................I mean where does the fun ever end at FWG?!!!On a side note - Would grafoil sheet work as the collector plates? Or too porous?Just thinking of alternatives to some sheet metals?Maybe too difficult to seal properly.I know I know - Give it a go for myself! ;@)Thanks for another great set of videos Rob!
lol - you should really try it yourself yes lol - but the graphoil works well to begin with but become porous over time so it fails early
It's probably been suggested before, but a 3d printable battery springs to mind, if you could print the entire plate that would be very cool!
Robert Murray-Smith Makes sense, lots of difficulties the more I think about it.
it has been suggested before mate - but it would be expensive and time consuming to make
Glad to see the laser being put to good use. :)
you should mate - it is a cool piece of kit
Robert Murray-Smith I'm sure! Just the first video since you got it I think. Must be incredibly helpful at times.They have one at my local makerspace, I really should go along and learn to use it!
it get s a lot of use mate - i just don't video it all
Forceps Robert, Forceps.
I think your willingness to share what you have learned is more than refreshing. I enjoy watching and taking part in my own small ways. Many thanks for sharing.
what you don't think poking small things around with my fat dirty fingers is any good lol
utility tweezers with a supermagnet inside one half of the steel handle. Helps to grind a steel bevel and put that on the unattached side of the magnet. Then I slide the magnet forward and back for an infinitely variable locking tweezers! I never f-up with small part when i remember to use these.!
Very interesting. Fumes from laser redepositing on mylar will be troublesome. Though not a viable production technique for a product where contamination is a concern... and production of "Sealed Wet Cells" is difficult, This really is VERY COOL work! I would love to send you some stainless instruments.
cheers mate - stainless instruments? - what are those lol
What I love most about your channel, is that I always learn more than what you are teaching. Like this video, after I watched it, and the other bipolar battery videos, I had a very enjoyable research gorge. I started by looking up different methods for making them already in place, and ended by trying to find out if two dissimilar metals can be wrung together, as in gauge blocks.I'm actually pretty certain that you could, but I'm willing to bet that the added steps and material needed would be worth whatever benefits there would be gained by wringing your two plates together. Anyway, thanks for the videos, and the wikibinge that usually follows!
that is an idea mate - nice one - care to try it and see? - it might be messy
Oh man, thinking back on that video... That is absolutely fantastic! If you could hear that sound all the way from the states, that was the sound of my mind blowing. Do you think you could pean plate using an oscillating tool with a buffing attachment, kind of like what you did with putting graphene on to glass, way back when?
lol - very cool mate - if you want to think about joining two dissimilar metals have a look at the pean plating vid i did
Robert...Now I am completely jealous of your cheating. A CNC laser, really?! Just kidding. I'm in the process of building my own CNC equipment. Some of the kits you can buy are outstanding or in my case I'll be piecing it together using equipment I've collected over the years. Thanks for the post.
Do you know how to outfit your own CVD chamber (large pressure cooker or some other vessel) with a salvaged magnetron? I would love to have a microwave oven I could pull a vacuum and/or replace the gas in. Any tutorials you are going to use for this sort of thing? I am just starting out with a jar and a hand pump for now, but better than nothing.
it is an awesome bit of kit mate
hi rob does thick layer of active material help or will lower my voltages ?
depends on the thickness mate - there is an optimum level
I loved the bgm so much Bensound - Buddy !!!
yeah nice song
Robert...also in what method do you prefer to obtain graphitic Carbon nitride..using the microwave? Or the oven/kiln? ...perhaps later this summer I may opt to use a Browns Gas welder, which disassociates hydrogen/oxygen to obtain graphitic Carbon nitride, if it proves successful for a viable method..I will definately let you know! :)
and also www.freepatentsonline.com/y2017/0022055.html
here is a great link. airbus 's cold fusion patents www.freepatentsonline.com/y2017/0025191.html
your welcome Robert! love your channel!
thanks mate - nice link
Is this demonstrating a substrate from graphitic carbon nitride? Or hemp? Or is it a mixture of both?
hemp - but Merlin is right mate - this is only an example of a technique - you should really try it with your own mixtures
Try it out , he already put it out all there.
Awesome indeed! You can make enjoying the first cup of coffee a lots more exciting than reading the rubbish in the newspaper, lol.... Great work Mate.
He never mentions Trump. . . Makes the videos almost unwatchable.
I love your ingenuity and intellectual mind Robert.. Keep doing awesome videos! Thank you for taking the time each week and sharing the latest :)
Wow! Awsome R&D open sourced work just love your pleasant manner, humility and infectious good nature..You just won the internet today, Sir; keep racking up the wins mate!
Are you avoiding using gel electrolyte because it's difficult to assemble large scale?
i have a tick mark lol - v cool
Robert Murray-Smith the tick mark that appears after your name...I think it indicates your account is verified.
it's an idea mate - give it a go - i don't know what verified means
Robert Murray-Smith mainly asking because you wouldn't need a separator material and the acrylic frame(gel won't leak). I see you've been verified by YT. congratulations!
nope - i just haven't made any and it is an extra step that is unimportant with reference to this technique - by all means use a gel
Tiny O rings should work if the metal is strong enough , no need for messy sticky stuff then .
good idea - give it a go let me know how it works out mate
Another great video, thanks for sharing your knowledge and experiments
Nice video Robert. Why don't you use pine sap with a little bee's wax instead of that carpet tape? Instead of pre- soaking first, try assembling battery first, then add the amount of electrolyte needed. Cap battery then heat to melt pine sap and wax to form your seal. This would be a cheaper way of assembling your battery. Let me know what you think.
no worries mate and thanks for taking the time to say so
I think Robert, that you're a fine teacher. You take the time to answer people back that comment on your developments and your strides forward for a better world. Most of the lug heads doing video's want talk to you. Thank you.
I think it is a good idea mate - but when doing videos for others you have to think of the easiest way it can be replicate and get a good job from materials everyone can buy easily - it most certainly can be done other ways - but folks need to experiment with that
it you be nice if you included some close up shots or pictures, keep it in mind for upcoming videos
