The lithium ion battery is probably the one outlier in that it's unique to mobile electronics but old portable electronics would use dozens of non-rechargeable batteries every year. Sure, but devices with replaceable batteries are theoretically easier to use longer. The average person buys a mobile phone every other year and discards their old ones. Practically every consumer electronic out there uses rechargeable batteries now which puts a limited lifespan on them.
