A typical lithium-ion battery has two electrodes and a liquid electrolyte within them that allows the electricity to flow. However, overcharging the battery generates excess heat than can cause the electrolyte to set on fire or explode.  Puncturing or shorting the circuit between the electrodes can also cause fires or explosions. Researchers have been working on the problem.  In early January of this year Stanford University professors announced a solution that involves using graphene to create a coating for the electrodes that shuts down the process when overheating occurs.

There are other solutions popping up and graphene is a component of most of them. A Spanish company working with a Chinese partner claims to have a graphene battery ready to go into commercial production by the end of 2016.  At the University of California at Berkeley a material called sulfur graphene oxide is part of another new battery technology, the Lithium Sulfur battery. Another researcher at Stanford is proposing an aluminum ion battery with electrodes made of graphite.  Chinese researchers introduced their solution on 28 March of this year in a paper entitled A Novel Aluminum-Graphite Dual-Ion Battery.

I continue to be impressed with the multitude of graphene uses.....right up HXG alley in being able to convert graphite to graphene by simple non chemical means.

dont care if its SPAIN or China...but  most likely is both
