This is already old and to be honest… rather miniscule improvement.
Carbon nanotubes were patented for usage in electronics along with means of integration and production back in 1992.
Same thing happened with synthetic diamonds in 1996.

Had we used those 2 materials alone from the get go, we would have already achieved and well surpassed current technology by orders of magnitude/

Technologically speaking, Capitalism spews out minor revisions that doesn’t bring real breakthroughs because its profitable.
In the long run, Capitalism brings out the WORST of what a given material is capable of (even though they already know how to do the BEST of what it can do) and brings out the ‘new’ once every 12 to 24 months.

Graphene’s band-gap issue was solved in 2009, and was already patented for industrial scale production before then.

We are toying in technological obscurity… its’ pitiful.

The Earth has plenty lithium. Lithium is not at all a problem. Don’t confuse the amount currently extracted and refined with the occurrence of lithium in the Earth’s crust. A scientist should not make that mistake.

Please document your charge that battery manufacturing is very carbon intensive. As a scientist you must have had that data on hand before making that statement.

Hydrogen is an inefficient way to power vehicles. As a scientist you must have cranked your way through the numbers and come to understand that.

And read some economics. Learn about economy of scale and why we are currently subsidizing EVs. If that doesn’t help, then look up a materials list for EV batteries and tell us what is in batteries that is so much more expensive than what is in an ICEV engine with its fuel, cooling and exhaust systems.

Well, I certainly can’t fault anyone who makes this much of an improvement in something having a giant caveat like charge time…..no job guys!
However….batteries are no answer to automobiles…..as the population of EVs grows, so will the earth’s small supply of lithium dwindle. Additionally, the mining and mfg. of the batteries as very carbon intensive.
As a scientist, I know that my mind can be “less than optimum” for figuring out the financial aspect of situations on it’s own power, so I decided to come up with a better economic solution as a
“science project” Hahaha…..hey, and you said we don’t have senses of humor! Here’s the “formula”
Take all the costs of making and having batteries for EVs, and put it in a pile. Next, Take the pile of money, each time someone would pay into it from the higher cost of an EV over a gasoline vehicle. Let’s call it about $5000, just for the battery (we’re only talking about batteries and power here, to be fair) Now, take that $5000, and multiply it by a million vehicles….that’s…..yes…5 BILLION dollars. Now….how many people can say: “Fuel cell membrane process cost subsidy” ?????Come ON people, batteries are for small devices……automobile size models are a gross waste of a natural and limited and valuable resource…..at $5000 or so of a subsidy paid up fron by the car purchase….the cost of making fuel cell power just got affordable, and, no more batteries to dispose of, or make from limited resources.
