EV Batteries Lasting Longer Than Expected, Stanford says

This is awesome news showing that the R&D into EVs is far stronger and better than ICE supporters have stated. 12yrs for a battery pack is on par with the life of an ICE engine. 

That stated, it would imply to me that like any auto, ice or EV, if taken care of they will last a much longer time than many expect.

Even though some degradation is expected, with ranges as high as they are getting these days, it's not really going to affect your day-to-day life if you're charging at home each night. A newer EV with a 320 mile range from the factory will still get 265 miles of range if the battery degrades to 80% after 12 years.  That's still a longer range than some base model Tesla Model-3s

I am really thinking an EV might be my next car.

The testing of all the new production Solid State battery lines is showing that the next generation of EV batteries should last two plus decades with 372 miles to 621 miles of range. Honda Solid state battery is rated at 750 km which is 466 miles and LG / Samsung has stated that their solid state battery will come in a wide range of sizes from 600 km to 1000 km so at this point, if you have a battery pack good for 621 miles of range or 1000 km, that is pretty much a solid day of road trip with charging at DC that evening or a level 2 over night at the hotel. Pretty much makes range anxiety a thing of the past.

Course I am consistently averaging 300 to 320 miles of range on my EV9 and as @Drew Dowdell pointed out even after 12 years on the high side at 265 miles, plenty for local driving.

I feel this is no different than the drop off in performance from an ICE auto in regard to HP/Torque except that EVs tend to not lose the HP/Torque like an ICE auto does while consuming more gas. Instead, you're just looking at battery degradation.

See my post in Random Thoughts, the complexity of modern ICE vehicles will create major problems for them moving forward.

This goes for the Toyota Hydrogen is better than EV approach, such a complex high compression engine solution that I cannot see it being better than an EV.

Of all of the bad automotive ideas, this ranks near the top.

I'm not sure what you're referring to. BMW is the one making a hydrogen engine (though they'll fail too). Toyota builds/built a hydrogen fuel cell.  The only difference between a fuel cell and an EV is how you "recharge" it.  It's just an EV with a different kind of battery, and it performs decently well.

The failure of hydrogen, regardless of if its an ICE (BMW) or fuel-cell (Toyota and others), is that it is expensive to produce both in dollars and in energy input.  You never end up with more energy from hydrogen than you put into producing it, thus making it nothing more than an expensive and hard to transport battery system.  Lithium and the other rare-earth metals might be expensive to get out of the ground, but you get to use them for well over a decade and a couple hundred thousand miles and they are input agnostic. EV batteries don't care if the electricity is generated by solar, wind, nukes, hydro, or @A Horse With No Name burning scrap wood in a boiler in his garage hooked up to a vintage steam engine.

I was thinking of their Hydrogen powered Corolla they demoed in Japan.

QUOTE: The liquid hydrogen-powered engine generates power by injecting hydrogen, the fuel, directly into the engine for combustion. The liquid hydrogen-powered GR Corolla uses a reciprocating pump that pumps the fuel, through the reciprocating motion of a piston when transferring hydrogen from the fuel tank to the engine.

Oh, yeah, they never actually put that into production like they did with the Mirai.
