There’s no arguing that batteries are an essential element of today’s electronics landscape. Without them our mobile devices would be a lot less mobile and we might still be crank starting our cars. The explosion in mobile electronic devices enabled by batteries and miniaturization has a major downside in the form of discarded batteries, the majority of which contain toxic heavy metals. Chemists have now discovered a new way to pass electrons back and forth between two molecules that could see the development of organic batteries that are lightweight and work without the need for toxic heavy metals.
