Most devices & gadgets are rechargeable nowadays. The only thing I have that still requires batteries is a headlamp but even those are available in rechargeable varieties. House smoke detectors need a battery too.

A good percentage of rechargeable cells are standardized too, they’re just not easily accessible. I don’t think it would take much to adjust the design of a thing to accept a replaceable battery in most simple items.
For example, I have a laser pointer that runs on rechargeable lithium batteries, you just unscrew it and put any standard 18650 cell in directly.
