For U.S. companies, the race for the new EV battery is on

I remember a few years ago reading a article that promised a liquid &#x27;fuel&#x27; that would recharge batteries. The idea being that you would pull into a gas station and expel your uncharged liquid and refill with charged liquid.<p>The liquid stuff might be a pipe dream, but I think the goal should be for electric cars to have a &#x27;instant&#x27; fill up option shortly. Having a network of such stations greatly aleviates issues of trying to squeeze every last watt hour out of every battery and lets range anxiety be less important. I dont really care as much if my car only gets 200 miles range if I can fill up in 2 minutes at any existing gas station.<p>Filling up of course can mean anything from the liquid fuel meme idea above to a fast battery-swap to some megawatt based &#x27;super fast&#x27; charger. It really doesnt matter

&gt; Democratic Republic of Congo produces more than 70 percent of the world’s cobalt...<p>The article talks about where certain raw materials are currently being produced (cobalt, nickel, lithium, etc.) without discussing where those materials could be produced (reserves). There might be vast reserves of those same materials in areas where it is forbidden to mine or where things like permits and regulations make it unprofitable to refine. Does the DRC really have 70 percent of all cobalt on the Earth, or is it just cheap to mine there due to slave labor and lax environmental laws?

I&#x27;m surprised Indonesia has the leading nickel production volume.<p>I always (uneducatedly) assume island nations would be poor in minerals.

Graphene Aluminum Ion is probably going to be the winner.<p>Only option with higher density, lower cost and heat reduction to make rapid charge times feasible (which are the key to adoption IMO).<p>At least from what I’ve seen.

No mention of cold weather. Do any of the new batteries keep their charge better when below freezing?

“The volume changes almost 300 percent if you’re doing it to its maximum capacity,” For silicon, really, is this correct?

So Elon Musk isn&#x27;t the founder of Tesla?

As always with the EV industry the non-Tesla entities are following such a weird strategy it almost seems like fraud.<p>GM sells two EVs, one that spontaneously combusts (bolt) and one that is the least efficient EV sold (hummer).<p>How about they fix their efficiency and reliability before trying to make a different battery chemistry work.<p>Likewise the new EV credit prioritizes inefficient vehicles by having a higher limit for large suvs and trucks.<p>We should just stick to technology that works, and focus on efficiency and scaling. Any new chemistry will still be a science experiment in 2030 (when allegedly gas vehicles will stop being produced)
