Thomas Edison

A rechargeable battery technology developed by Thomas Edison more than a century ago has been upgraded by Stanford University researchers.
The Battery, Thomas Edison was one of the first to create a rechargable battery more than a century ago. Recently Standford University researchers took interest in it, trying to convert the old shabby battery into a battery that can charge in just a few minutes in 20th century cars. This battery is mostly used to store surplus from solar panels and wind turbines.

This research can be found in Nature Communications, and the original battery consists of a cathode made of nickel and an anode made of iron inside of an alkaline solution. Carbon is a conductive element but it improves performance, leading Standford to use graphene, a sheet as thin as a single atom made of carbon. They grew nanocrystals of iron oxide onto graphene, and nanocrystals made from nickel hydroxide onto carbon nanotubes.
