Graphene Layer Speeds Battery Recharge Time

Two hour charge could be reduced to 10 minutes.

Is there anything this stuff can't do? Wonder material graphene could make an appearance in the batteries of consumer products as early as next year, according to Vorbeck Materials.

Researchers at the company say that the carbon lattice can massively cut the amount of time it takes to recharge a lithium-ion cell – from two hours or so down to just 10 minutes. Other benefits include longer battery life, and lower operating temperatures.

Company president John Lettow told IDG “There are many problems with battery materials at present: they take a long time to charge and discharge, they do not store much energy, they have lower than desired cycle life, and they can heat up and short circuit, causing safety problems.”
