Graphene can make Titanium-Dioxide batteries last 3 times as long

Researchers from PNNL discovered that adding Graphene to Titanium-Dioxide batteries can make them last 3 times as long.

This might prove to be a good replacement for Lithium-Ion batteries which perform great but are very expensive. Batteries made of Titanium-Dioxide will be much cheaper, and are less fire-prone.
