That is not the only use of graphene technology even in battery storage graphene can improve it.
But we're after the gold, right? 
Graphene sieve turns seawater into drinking water

New research demonstrates the real-world potential of providing clean drinking water for millions of people who struggle to access adequate clean water sources.
Graphene-oxide membranes developed at the National Graphene Institute have already demonstrated the potential of filtering out small nanoparticles, organic molecules, and even large salts. Until now, however, they couldn't be used for sieving common salts used in desalination technologies, which require even smaller sieves.
Previous research at The University of Manchester found that if immersed in water, graphene-oxide membranes become slightly swollen and smaller salts flow through the membrane along with water, but larger ions or molecules are blocked.
