The man who brought us the lithium-ion battery has an idea for a new one
What I'm worried about is the waste of lithium and other battery/accumulator metals. In theory, people should turn electronic devices and batteries to recycling facilities, but a large part of the population ignores the rules and throws their gadgets into the trash when broken...I wonder if someday we will find a way to "separate" trash on atomar level (i.e. put arbitrary stuff in on one side, get raw atoms on the other side)...
