I was just wondering if anyone else had seen a better article that says what the substance is.
One of the main reasons for using Lithium is its density. Whatever replaces it must also be light.

I've looked for an actual scientific paper on the research and found nothing.

Meanwhile, several Tesla drivers have complained about charging stations not working in these extreme conditions.

Near 95th Street and Western Avenue in Evergreen Park, many Tesla owners were stranded with dead batteries from the cold, and not enough working charging stations at that location.

"Our batters are so cold it's taking longer to charge now, so it should take 45 minutes, it's taking two hours for the one charger that we have," Tesla owner Brandon Welbourne said. "I have seen at least 10 cars get towed away from here because the cars, they died, they've run out of battery. It's too cold, it uses too much of the energy to try to keep the car somewhat reasonable temperature, so everybody is getting towed away and we have nowhere to charge."
...
For many drivers, it was too late, their cars died during the long wait, and they had to leave their vehicles stranded and wait for the stations to get up and running again.

I think the market will eventually decide the proper place for EVs. Whatever happens, ICEs are not going to disappear in the foreseeable future.

I worry the push for long distance electric trucking will be a nightmare. We just had a days of frozen temps with all major highways shut down. A fully fueled diesel can idle for days providing heat for the operator, and start moving quickly once the road opens.

I just read a story about a guy who had to put out $14k because the frame broke on his new Tesla.
Brand new, 115 miles on the odometer. I would think that should be covered.

I've said for several years now that the energy density (joules per liter/wh/kg) for common batteries is reaching low explosive (ANFO) range and eventually will be weaponized. The more energy dense, the more your battery resembles an explosive.
Yes, fossil fuels burn and are dangerous but the combustion is seldom of an explosive nature unless the fuel/air mixtures for commonly used fuels are just right and even then you usually see a fast burning flame surface propagating.

I've said it before here: there are plans for massive battery installations under cities to store energy (at the point of load) to back up renewable power systems.

What could possibly go wrong?

Ha! Nothing can go wrong, everybody knows that, until something goes wrong, and then, "Oh, we didn't expect that".

Interesting because "underground" means it will have to co-exist with sewer and water supply systems under there. I smell a rat, literally, rats too. Big, gnawing, rats, with teeth that can gnaw through concrete.
