When one discovers that the batteries from EV’s burn at 2000 degrees or more, and the chance of said batteries catching fire during recharge is any more than zero percent, not in my home.
Sodium ion don’t burn the sodium is in salt or ion form. Does table salt burn? Lithium ions do depending on chemistry. LFP don’t burn if they use the right electrolytes. NMC can be inhibited LG just commercialized their version of inhibitor. If you have a smartphone, tablet or laptop you have the same NMC cells that could burst into flames at anytime as well. They don’t usually.

BYD already inhibits their Bladepack it can pass the steel spike test without flames or flammable vapor. Your smartphone,tablet or laptop would burst onto flames instantly with a nail through it.

The future is electric drivetrains, how they get the 800V electrons is up for debate. Be that in a series hybrid like this CATL or BYD. Be it with fuel cells or some form of linear alternator, or gas turbine.
As higher energy density cells come to market purely electron to election makes sense for even 800 mile range vehicles. 600 is possible today with model S sized vehicles and that’s at 390wh/kg some of the high density cells are hitting 900wh/kg nearly triple the capacity for a given sized pack and weight.
The smart thing to do is have a pack that covers 99% of driving for most people and have a means to cover the edge case 1% with either a on board genset or fuel cells or have something modular and rentable.
A standard 400-800V interface would make that module cross platform it is after all just 400 or 800 volts DC. Have a standard of.volume and interface plug so anyone could make a modular design for the 1% or less per year someone would actually need to go farther than a couple hundred miles in a day before coming home.
While this new concept sounds somewhat promising, one must remember there is usually a lot of hype with these new processes & also it is probably a rather complicated setup & thus rather expensive. Many of us can’t afford ANY new vehicle, much less a lot of them that are actually rated particularly troublesome. I drive an old car that appears to be good for several more years, & while it is never completely trouble-free it certainly has less than the usual number of defects that a new EV would probably have.....while costing a lot more money.
