The electric vehicle market has been experiencing explosive growth, with global sales surpassing $1 trillion (approx. KRW 1,283 trillion) in 2022 and domestic sales exceeding 108,000 units. Inevitably, demand is growing for high-capacity batteries that can extend EV driving range. Recently, a joint team of researchers from POSTECH and Sogang University developed a functional polymeric binder for stable, high-capacity anode material that could increase the current EV range at least 10-fold.
A research team led by POSTECH professors Soojin Park (Department of Chemistry) and Youn Soo Kim (Department of Materials Science and Engineering) and Professor Jaegeon Ryu (Department of Chemical and Biomolecular Engineering) of Sogang University developed charged polymeric binder for a high-capacity anode material that is both stable and reliable, offering a capacity that is 10 times or higher than that of conventional graphite anodes. This breakthrough was achieved by replacing graphite with Si anode combined with layering-charged polymers while maintaining stability and reliability. The research results were published as the Front Cover Article in Advanced Functional Materials.

Normally for both government and privately funded research, the patent rights are shared between the university and whoever funded the research. In the case of the government, I would be surprised if they would be inclined to license much less sell their patent interest to a foreign entity.
I’m familiar with a few cases where privately developed technology was actually erased from the public domain by bringing it into the Fed’s classified world. The private patent holder retained patent rights but had no knowledge what the government was doing with it re. just sitting on it doing nothing or licensing it to other companies for classified applications.
I’m also familiar with situations where private companies kept a technology as proprietary knowledge without patenting solely to keep it off the Fed’s radar thus keeping it from disappearing into the classified world.
Bottom line is that the Feds make big bucks as patent holders.
My opinions…
Often said: Well, it was close to working. It could have worked. They tried hard. At least they didn’t screw it up. Nobody saw them screw it up. You can’t prove anything.
There could be an improvement in charging efficiency (reduction in thermal loss), but not a huge amount.
Only capacitors have the ability to charge quickly, but there is no way at the moment, to my knowledge, where you can charge a capacitor quickly and have it drain slowly over time.
Ideally, you should be able to charge in a similar time it takes to fill up your tank and that should give you about 5 hours of travel time, similar to a fuel car.
Precisely
Rather like the holy grail. Lots of lookers. So far no finders
Bwahahahaha
Oh those guys
To me, hybrids is where the sweet spot is. They can keep improving the battery while still using gas or diesel to get around.
Hehehehe...
Well, they’d better make sure these batteries don’t short. Having 10x the energy is 10x the bang!
I think I have read about 8 or 10 of these “breakthroughs” in the last year.
Don’t buy it, at all.
Just 30 years away!
Which way did he go?
Like cancer cures they are always 10 years away. All nonsense anyway as we only have 8 years before global warming warming kills us all.
Everyone else got it.
You did a poll of all the readers even those that did not leave a comment - pretty cleaver.
Spell & grammar checkers are your friends.
1. a heavy, broad-bladed knife or long-bladed hatchet, especially one used by butchers for cutting meat into joints or pieces.
2. a person or thing that cleaves.
Thanks I’ll sure to senselessly nit pick you in the future
See #78 above. You still haven’t learned.
