As you know by now mate, I often have additional questions and suggestions after each video, but I have to say, well done Rob! Fantastic video. It had everything: Time for the theory, real world example in practice, along with instruction as to how to replicate! Probably one of your best right there!

Not bad, loved the video, thanks! In the RAF around 1979, there were batteries in survival equipment /kits (such as life raft kits), that had batteries that you submerged into the ocean (seawater). We were told that these were used to run a flashing distress beacon, and used saltwater as an electrolyte. Not very powerful, of course, but it could save your life by alerting search aircraft to where you were!

If I'm understanding it correctly, someone could in theory insulate each side with a biodegradable wax or wax paper, roll it tightly, and somehow activate the electrolyte when ready use, would have an AA battery for 2 hours that's entirely biodegradable and cheap? I like it. Sounds like it would be invaluable to underdeveloped countries

Reminds me of the so called stone paper made with 70% Calcium carbonate and 30% HDPE. It immediately made me think about its applications for battery making

You are quickly becoming my favorite person on KZfaq (masses of people are wasting the best invention, information on the internet!) You can learn or do anything now if you use creativity and your brain. Thank you for your contributions

The Disposable batteries probably wouldn't be so popular if, they didn't hold such a high amount of mAh per charge versus the rechargeable batteries. Most "small" rechargeable batteries do not have a high mAh per charge. They are superior in mAh per lifetime of the cell. Great video Robert! You are a encyclopedia of knowledge & a inspiration to us all!👍

Outstanding presentation Robert as we should be more aware of the ways we can store energy in a safe manner without destroying the world we live in. Please keep up the good work and thank you.

"Water-activated" batteries have been around for literally decades; they see use in radiosonds (weather balloons) and sonobouys. Nice DIY project. 🙂

Bob , Many years ago at sea we had lifejackets fitted with small lights . The battery powering these only came to life when immersed in sea water..........

Thank you for sharing, a very nice find on this newly published paper. There are literally hundreds of avenues of optimization on the foundation this paper describes.... application-specific / form factor avenues, processing, materials / recipe...cheers!

You're right on about amazing paper. I visited a paper mill years ago and it was beyond belief what goes into paper production. The mill is a multiple story building and blocks long. They grow there own special trees and do great job being good to environment. Sad that we live in a world lead by pervayors of completely false history; the true origin of paper battery being but one example in a mountain of deception. Greed will protect the AA battery, and unlikely heroes will make the scene rescuing us claiming undeserved credit for things that have been around for 100s of years.

Thank you for another fantastic presentation that I get to play with.

I love these home-made battery videos! I never get tired of them. Especially the ones made from cheap, easy to find materials. One of these days, I want to build a home made battery that can charge my phone, and be recharged with solar or some other novel device.

" one of the reasons I love paper" Thanks for this excellent how to! Thank you very much indeed!

This is very useful to me, thank you.

Thank you for keeping us up-to-date, as you normally do! Erich from New Zealand

I agree paper batteries have been around for a long, long time. I built one for a school project back in 1974. We utilized paper in a plastic bottle, mine was D cell size.

Thanks for reviewing our work mate. Keep up the good work.

Good video, would like to see a longer, broken down, step by step way to make the battery. Ether way, definitely something to try out!

Great video! I really loved that you edited the instructions over the video. I try and take notes when I watch and having it all written out is so helpful. Much appreciated Rob.

any and all of these open source articles are fantastic, saving the world and ourselves one paper at a time. More power to you Rob

Great little video. I just finished making a blog article on this topic including that paper and now I've found the vid! Cool. I linked it in my blog.

A great little battery Rob :-) Whatever happened to your paper battery you was making some years ago? I can remember you had a pile of paper cells that you had made and taken days to assemble.

Interesting, few plastic tubes of different battery sizes with conductive ends, slight change in the morphology, few mL of electrolyte, push in a pre-rolled dry cell, pop the top on and presto your own AA battery or whatever. Remove roll when dead, more electrolyte another roll and on your way. Take the old paper, put in an electrolysis cell recover the zinc and away you go again. Very nice, bugger off disposables.

Thanks Robert

Watched this one and was so interested I allmost forgot to like. Great video.

Robert great video sir ..The issue i have with off the shelf rechargeable NIMH batterys like AAA and so forth is the lower voltage in some cases hurts performance of what its running but thats that

I use NiMH cells because they are very leak resistant so I can leave them unattended and not worry much about my devices having leaking battery issues... also their incredible cold weather performance and insane power density compared to other AA cells are also nice to have. But this is still interesting since paper is a wonderful material and NiMH batteries are typically not very cheap to make or flexible... things that paper batteries are good at... though NiMH total cost to own is still cheap since the Japanese made cells are rated to go for 2000 cycles. But still, paper batteries like you show being water activated might be really really good at emergency batteries that are shelf stable until activated by getting them wet.

Great Video Earthling Bless Up

Amazing! I always feel empowered to experiment after hearing from you. Do you have a forum your listeners can share results to?

Thanks Robert that's really interesting.

There's a paper about making a battery out of paper. This paper inspired us to make paper batteries. Paper is recyclable and biodegradable. Both the premise and the physical structure of this project have alot in common, strangely enough.

First, thanks for great video Robert. Second, I like the point that you made about Standford. 😁 I share your experience on that. Third, keep up the good work. People like you are what made your your nation, continent and human kind great.

Think you for the link. I downloaded my copy. And hope to make this one day. 👍😎

Wow! That's neet! I'm going to download the paper and give it a try. I build my own battery packs for E-bikes, so I'm wondering if this will ever progress to rechargeable batteries that could run an e-bike. Well, thanks again for another excellent video and head scratcher! 😎👍

Wouldn't it be lovely if someone made a rebuildable AA battery sleeve, little stainless thing with a thick graphite rod in the middle to wrap your paper around!

A multilayered stack of those wired in parallel might be good for a bit. :O)

Excellent demonstration. Thanks for your efforts.

Another incredible video that blew my mind. Thank you!

Thank you :)

Paper is truly one of the most underrated and amazing substances human beings have come up with...

Finally gets to the point at 2:23

Can't wait to see what you to come up with as an improvement Rob. Hmmmm all things being considered it may be a bit of a challenge . Best thought i have is using already used office paper or finding industries that use large amounts of paper like news print. Not so sure news paper would be strong enough although after being painted it might be fine!

Thanks Robert. I'll be trying that one.

Excellent video and ingeniously simple technique! Could you please do a video on decomposition of polymers by microwaving, where the by products are pure hydrogen and multiwalled carbon nanotubes?

This might be great for a long-term storage method to use as an emergency recharge of a cell phone as long as you had a simple voltage regulator.

Wonder if a whole roll of paper towels would last all night lol.

Great find, it would be great if the industries move with this concept, many thanks Robert.

One could argue that paper batteries go all the way back tot he first ones. (well after the bagdad ones) The Volta Pile was paper between copper and zinc disks.

Where are you with your old paper pouch batterys? I don't recall a conclusion to that production. I struggle to remember with what chemistry, but I always fancied making long Peper batery rolls, housing the cells in pipes and those in 45 gallon barrels. Haven't gotten round to it yet.

I haven't bought disposable AA or AAA in ages. I use rechargeable ones and downgrade them as they grow old (ex: from flashlight to radio, from radio to remote etc), finally packing them up with other batteries to a send them once a few years to a local battery recycler handler.

You're a modern Merlin. Thanks for the straightforward explanation, as always.

I’ve been waiting for you to do that with your conductive ink

I have got to make one of these.

What a great little battery!!! Biodegradable too!!

Great stuff! Thanks Rob!

Absolutely brilliant. Thanks for sharing it.

Amazing. Thank you!

This is mind blowing!! I've got to imagine if you put a layer of insulation on top of a shower, you could roll it up and slide it into a sleeve, thereby condensing it. If you were to run these in parallel, I also imagine you'd get significantly longer life out of them too

Always Quality stuff !

Brilliant, got to make one now! Thanks for sharing.

Yep, if this catches on, we will completely exhaust the element Zinc. Still a great experiment, but just as you said, this is nothing new. Where do we take this? The resulting battery size to compete with a AA would be as big as car to power that clock for a standard year. I am 1000% with you on the battery in the landfill problem. Oh, can you explain how zinc becomes biodegradable, please? I could make a fortune growing zinc.

Naughty boy Robert. 🤔 Not uncoiling that extension lead before plugging that hot plate in. 😏 Please explain the dangers in your next video. Otherwise, great info as usual. 👍👏👏

This is awesome! Thank you, Robert :-)

Robert, you are an amazing inventor.!!!

What a cool experiment! One question, and maybe I'm really stupid here, but where do you purchase things like zinc powder? This was a terrific video, and I was genuinely blown away with the size of the battery market.

Junk mail battery... Outstanding .

That's awesome 😎

Ha, this is a gem of YT recommendation. I like this guy haha

Brilliant!

so simple and yet so awesome!

My pardon, it can also be used to find new elements, with a bank of centrifuges tuned for that atomic weight.

If these can run in series and are rechargeable I'm thinking plying and gluing to the back of solar panels to supply 24/7 power without the bulky Li ion box.

So Stamford took a leaf out of Edisons book then.. Taking anothers idea and brilliantly marketing it as their own

Way back , Monday thru Saturday , Caveman , home delivery , but on Sunday , you come to the quarry to read ,

i'm surprised your conductive ink didn't make an appearance

This was fantastic! You rock!

I'm just looking at this 60cm x 500m roll of packing paper I have by the desk and developing intrusive thoughts....

seems to me that you'd want to find conductive toners so that you could print these out by the ream.

A paper on paper batteries should have a piece of battery printed at the end of the paper, so the reader can try it out.

I find all your stuff real interesting, always watching it at work, i would be interested in any you have or could do on hydrocarbonization,

Another awesome Battery video Robert. I just wonder, 'could you do a video over a Rechargeable Paper Battery? My brothers Sail Boat comes to mind, and this type of Battery maybe the solution I've been looking for. Thanks again for your good Heart in sharing your hard earned knowledge with me.

seems like I remember making a battery about 40 years ago in the 9th grade science fair. Forget the details, seems like I used a paper towel, a copper penny, a nail then soaked in lemon juice. it was enough to power a calculator.

Fascinating thank you

That's brilliant Robert, thanks for sharing 👍

always enjoy your battery making videos, well done sir

Batteries existed for thousands of years 😮

The duration can be extended considerably and a study of the alkaline pulping process would reveal the detail. But such an old information comes from an innocent time and would be counter productive in terms of recycling.

Thank you for the video and history lesson

Would be interesting to make some of that bullet proof paper that is made by chemical sorting by enzymes instead of harsh acids or alkali's, or the typical mechanical pulping, so the cellulose molecules are not broken down just apart, I would think that if process was right, it would cause aligning the cellulose in mostly one direction, so breaking it down further with a dehydration compound would leave aligned carbon chains :)

...because the chargers always break down and you cannot even get the chargers in the store anymore. I so do always feel the urge to tear the batteries.

To turn it into a AA form factor, I assume you would roll it up. Would it short circuit if you rolled it up? Would another piece of paper on top stop that from happening?

This looks good on paper - - - and on your voltmeter too :) .

Great stuff, as always!

Doable at home, not necessarily easy. Great video.

I know kinda off topic but could you point me to the video you did a year of more back about a rod wrapped with wire to evenly coat sheets with a fluid…what is is the the name of that rod?…I remember you saying that they were very expensive to buy but one could make one as you did varying the gauge of wire to create the thickness desired…I have searched but just can’t find it nor do I recall the name of that rod… Thanks sharing all of your knowledge experience and insight!!!

Respect and gratitude

Great video as always 👍 👌

Makes me wonder if there's anywhere that sells entirely emptied and cleaned inkjet cartridges for experimenting with wild and weird inks like this. Heck, there's an idea for your shop. Old HP ink carts, re-done for different scientific-type or production purposes. Literally-printed circuitboards with the conductive stuff and old HP #62 blacks :P

Always back In time. I was looking at battery tech over ten years ago, a uni picked it up and then went for the patent and then everything vanished. This was back when batteries were slow and super caps were great. I always remember the A4 paper and plastic sleeve capacitor.
