BioSolar Targets 459 Wh/kg, $54/kWh Lithium-Ion Battery

It’s time for Super Cathode…

BioSolar is new company on the radar that announced development of breakthrough technology to double the storage capacity, lower the cost and extend the life of lithium-ion batteries.

They set a clear target of a shocking 459 Wh/kg at $54/kWh and announced extension by 12 months (to June 2016) sponsored research program at the University of California, Santa Barbara.

We can already guess what name (vaporware) the company will get if they will fail to deliver like EEStor, but at BioSolar there are several Ph.D., including Alan Heeger, Ph.D. (Nobel Laureate), on board, which gives us hope for better batteries.

BioSolar is working on the cathode (Super Cathode), which will be better in every aspect (capacity, cost, life, fast charge).

To build a full cell, a conventional anode will be good enough, which makes us wonder why some other companies are working on the silicon anodes for higher capacity if there is so much still left in graphite anodes.

About the project:

“BioSolar, Inc. (OTCQB: BSRC), developer of breakthrough energy storage technology and materials, today announced that the company has signed an agreement to extend the funding of a sponsored research program at the University of California, Santa Barbara (“UCSB”), to further develop its super battery technology.

The lead inventors of the technology are UCSB professor Dr. Alan Heeger, the recipient of a Nobel Prize in 2000 for the discovery and development of conductive polymers, and Dr. David Vonlanthen, a project scientist and expert in energy storage at UCSB.

BioSolar’s research program with UCSB first started in July 2014 with a focus on low cost and high performance materials and structures for supercapacitors and batteries. Based on the technical breakthroughs from this 2014 program, the Company focused its efforts on developing a super battery technology. BioSolar believes its breakthrough technology can double the storage capacity, lower the cost and extend the life of lithium-ion batteries. This extension funds the research program for another 12 months until June 2016.

The Company recently announced that it has jointly filed a patent application with the University of California, Santa Barbara (“UCSB”) in order to protect intellectual property rights which forms the basis for the company’s super battery technology.”

Dr. David Lee, CEO of BioSolar said:

“We are pleased to renew our agreement to fund a sponsored research program at UCSB to further the development of our super battery technology. As one of the top research universities, UCSB is considered to be a global leader in bioengineering, chemical and computational engineering, materials science, nanotechnology and physics. We are confident that this team of scientific professionals will continue to progress the technology closer to our goal of achieving a $100/kilowatt-hour cost milestone for energy storage.”

Tesla used the NCR18650A in the Roadster, the NCR18650B in Model S is 275 Wh/kg (at the cell level) and the new 90 kWh packs are obviously beyond that. I looked at the BioSolar website and their battery claims are ‘calculated’ i.e. they haven’t actually built any batteries yet, just supercapacitors!

Also no mention of volumetric density, which is the reason why the Model S is a such a large car.

Tesla Roadster did NOT use NCR18650A. It uses LiCo cells with MUCH less capacity. Roadster 3.0 is upgraded with the newer Panasonic NCA cells which is why the capacity has increased so much. Tesla Model S does not use NCR18650B either and the NCR18650B is 243 Wh/kg not 275 Wh/kg. I can’t remember what cell it actually uses, but long story short is NCR18650B doesn’t have adequate power density. Energy density has to be traded for power density.

225 Wh/kg is very close to the cell the Model S has been using. Obviously the new Silicon/Graphite anode the 90 kWh is using likely greater than that.

I like Tesla as much as anyone here, they continue to surprise me (first EV to use Silicon/Graphite Anode & 0-60 mph in 2.8 seconds). But I’ve been noticing a trend where as soon as Tesla touches something, its abilities become exaggerated or are automatically better than anything else. Let’s stick with facts.

Actually Tesla is probably closer to 240 Wh/kg. My mistake. Rest is correct though.

Not the part about the 90 kWh battery obviously having a higher Wh/kg. When Panasonic announced them back in 2009 the silicon containing anode weighed enough more that the Wh/kg decreased even while the Wh/l increased. The new cells are unlikely to be unchanged and they may have lost some weight, but maybe not.


The Model S has a highly modified NCR18650BE. As a result, the cell itself is actually lighter, which means a specific energy higher than 250 Wh/kg. We don’t know exactly.

Now the new 90 kWh pack has some silicon in the anode, which means the specific energy probably approaches 270 Wh/kg.

Here we go again

*Insert usual comments about breakthrough batteries here*


“To build a full cell, a conventional anode will be good enough, which makes us wonder why some other companies are working on the silicon anodes for higher capacity if there is so much still left in graphite anodes.”

Tesla Model S now uses graphite/silicon anode.

Your statement is as equally as true as saying: “Tesla Model S 90 kWh cells makes us wonder why some other companies are working on high voltage cathodes for higher capacity if there is so much in graphite/silicon anodes”

The answer is that improving either results in better batteries. BioSolar specializes in cathodes, others (i.e. Amprius) specialize in Anodes. Every aspect of batteries should be focused on to improve performance.

“Calculated” my a**.

Just posted numbers that make nice round 2x, 4x, so they can get investors.

If its “R&D” we will see batteries in cars in … 4yrs soonest.

At the annual liar’s contest there were two finalists. a used car salesman and a battery researcher. The battery researcher won easily.

Except that here there is a Nobel Prize winner involved. When you come to that kind of achievement, you deserve at least to be listened to and considered, so biosolar announcements are interesting. Of course it will have to be proved with a sample cell, but 459 Wh/Kg means a battery Model S size could store the magic ice terminator energy content of 200 KWh. That perspective alone is worth the check.

yes eestor is a tad late but shouldn’t be counted out just yet. there is something there there. and it’s close to production ready.

their phase 3 test for their cap application will be out soon. watch for it.

and soon they will refocus their efforts on storage once they have a cap market joint venture established with a big shop.

Is that another “EEStor Fan Fib”? 😉

The guy who ran the EEStor forum finally closed it, because enough facts finally came out to demonstrate EEStor’s claims had always been vaporware. There were a couple of die-hards still left who still thought EEStor might produce something, despite all evidence. “Fibb” was one of those two.

I was “Lensman” on that forum.

lens that new handle needs work. lol

hey don’t be a stranger:

the eestorblogger got burnt out and was not excited about disruptive caps.

and you, you were one of eestor’s biggest fan boys. you even wrote up an eestor faq website and defended eestor strongly for many years.

i predict you’ll be back singing their praises someday when they have proven they have commercially viable technology by signing a jv deal or two.

Really, modern batteries have too little cathode for the anode? I doubt it.

Once the patent has cleared they should be able to tell us what its made out of. Until then I’ll just ignore this.

$54/kWh? Do they actually expect people not to laugh at such a claim?

Claims from wannabe battery makers should be read like the National Enquirer. Often entertaining, but nothing to be taken seriously, and certainly not to be believed.

“My my top advice really for anyone who says they’ve got some breakthrough technology is please send us a sample cell. Okay? Don’t send us PowerPoint. Just send one cell that works with all appropriate caveats. That would be great. That sorts out the nonsense and the claims that aren’t actually true. Talk is super cheap. The battery industry has to have more B.S. in it than any industry I’ve ever encountered. It’s insane.” — Elon Musk

If Elon said it’s insane do we have to get ludicrous?

“You’re actually looking for [new battery] tips in a supermarket tabloid?”

“The storage battery is, in my opinion, a catchpenny, a sensation, a mechanism for swindling the public by stock companies. The storage battery is one of those peculiar things which appeals to the imagination, and no more perfect thing could be desired by stock swindlers than that very selfsame thing. … Just as soon as a man gets working on the secondary battery it brings out his latent capacity for lying.”

Thomas Edison, Feb. 17, 1883, who then proceeded to prove his claim was true, at least for him, some years later by overpromising and underdelivering on his NiFe battery, which had to be recalled from the market shortly after its initial release, and then spent several more years in development before being re-released. It was better than L-A in some ways, worse in others, and more expensive. But then Edison had a long history of claiming that he’d solved some particular problem and was just a step away from commercialization, well before that was the case.

Exceptional claims require exceptional proof.

A powerpoint deck is not proof. Scientific, peer-reviewed papers are much better, but the proof is in the UPS package that ends up on Elon’s desk from battery development companies containing sample cells.

This penny stock made a hike from $0.07 to $0.52 in the 2 weeks after this breakthrough announcement before collapsing to $0.30 again.

I think that goes a long way in explaining what’s going on here.

Like Grandpa use to say, “If it sounds to good to be true, it’s probably bullsh!t”.

A bit like a sedan that would accelerate faster than a 911 Porsche.

Send me a FREE sample, not a powerpoint, to prove the claim.

We’ll all laugh until one of these startups delivers, and then they will be the one laughing. Which one? Who knows? But the prize is huge, the future really, so much depends on this one technology.
