Who wants this battery in their blank Slate?

Things at CES aren't real, they can't hurt you.

Just don't breathe the vaporware.

This one is a bit of a slog at 45 minutes but it's the best interview I've seen with Donut. Damn I want this to be real.

One of the more fun comments I saw from the CEO in one CES interview was "Hey, in a few weeks somebody will be tearing our first motorcycle apart in the lab, and then you'll know all about the battery". I get that a small company in the middle of patenting things doesn't want to release proprietary information. I also get that somebody making bogus claims also doesn't want to release proprietary information.

Here is one fun, if totally deranged, thought path to go down. There have been a raft of cancelled battery production contracts. In the billions. All the cancellations conveniently pointed to the topic we're not allowed to discuss on these forums ("p" word). Now this is totally batshit crazy. But what if those OEMs had advance knowledge fo the Donut Labs battery, and realized that their current plans were rendered useless overnight. So they terminated the contracts. Took the billions in lost investment. And are now signing contracts wtih Donut Labs to build batteries.

Just saying that in fun. Again, it's a batshit crazy conspiracy theory. But sometimes those are fun. Now if you'll excuse me, I forgot to put on my tinfoil hat this morning. Because you know, the aliens are trying to reprogram my brain.

What I am most excited about is that solid-state batteries handle cold weather better than traditional NMC or LFP. They don’t rely on liquid electrolytes, which can freeze or lose efficiency in low temps. The solid materials stay stable, so they charge faster even even at freezing temperatures. Anyone who has charged their EV when it’s below 30 degrees F can relate to this.

Well, I would say what are the terms and conditions of the battery contracts that would allow an OEM to cancel a contract just because there is a better technology on the horizon? Generally, "a better technology came along, so we are cancelling our contract with you" is not a term in a contract that I have ever seen. That would be akin to a "termination for convenience" clause that are rarely included in commercial purchasing contracts. Government contracts have termination for convenience clauses that have a long-standing legal basis, which allow the Government to protect taxpayer monies and reallocate funding to new and arising requirements.

I think on current EVs, if the battery is detected as being too cold, the charger current will be at least partially put into warming the battery. Once it's a bit warmed up, and can be charged at a normal rate, that very charging will provide plenty of heat, and the heater would be turned off. Early EVs had little provision for heating or cooling a battery.

Yes, when it's cold my NCM EV battery will be slow to charge and give less range guesstimates.

Luckily I live in a year around warm climate so I never see range loss....
