Three companies in China recently launched graphene-enhanced lead-acid batteries, and they claim the graphene materials boost the performance of the batteries. While it is hard to verify the exact content and composition of these batteries, it seems as if graphene is finally starting to enter the battery market.
First up is Tianneng battery, which offers its TNEH Series Deep Cycle Black Gold Battery. The company says that the graphene expands the cycle life of the batteries and improves the performance at low temperatures. The TNEH series offers a 20% longer cycle life compared to the company’s non-graphene batteries. The same battery also offers a 5% increase in capacity at low temperatures.
