How long is a "rather short period of time"? There are decade old EV batteries still in use and over 80% SOH.
And fuel definitely goes bad. It doesn't work like in the movies where you can just find a 30 year old car in the desert and grab more fuel for your awesome roadwarrior vehicle. You can use additives to make it last longer and store better, but still.
As for "exotic materials" we're figuring out new battery chemistries at a record pace. Some are better for vehicles, that need a good kWh/kg ratio. Others are better for grid storage where kWh/€ is a more relevant measurement.
- elihu 3y agoI think the point the post you're replying to was making is that the gas tank itself doesn't usually go bad. It's true you can't just let gas sit in a tank forever, but with EVs it's also true that you can't usually just leave a battery to sit unused for years; eventually, it'll self-discharge below a threshold where it becomes permanently damaged. I do agree that battery "problems" are exaggerated -- most will last a very long time, and batteries that don't use cobalt and nickel are available now. Sodium-ion might be relatively common in a few years for low-end applications.
