Comment on If you managed to create batteries that can last for a century, will charging be redundant?

It depends on the power density. A battery with the current power density but increased longevity isn’t going to be as useful as you’d think.
A battery that is able to have the same power output as current batteries but last a century is going to be a weapon of mass destruction.

…. Is exactly what we need. People bitch and moan about how difficult it is to replace phone batteries, but this would make it unnecessary. More importantly, all those people who replace their phones every 2-3 years as the battery stops lasting a full day, would no longer have that excuse. If we had increased longevity, there’d be less electronic waste as people keep their devices longer
Or think about things like grid storage - a lot of the high cost is how long they last, so increased longevity is critical for that investment to pay off.
Or v2g. People are finally coming around to trust that EV batteries will last longer than they will own an EV, ut most of us still don’t trust vehicle to grid connections to not unnecessarily age our vehicle battery

But less electronics waste is less profit. If everyone who bought a 2 year phone bought them every 4 years instead, that’s a 50% drop in sales.
