GRAPHENE BATTERIES-A REVOLUTIONARY BREAKTHROUGH IN SMARTPHONES MARKET

Briefly, graphene is a composition of carbon atoms tightly bound in a hexagonal or honeycomb-like structure. What makes graphene so unique is that this structure is just one atomic layer thick, essentially making a graphene sheet two dimensional. This 2D structure produces very interesting properties, including excellent electrical and thermal conductivity, high flexibility, high strength, and low weight. What we’re particularly interested in is the electrical and heat conductivity, which is actually superior to copper — the most conductive metal element. Graphene batteries would allow smartphones to be thinner or offer more battery capacity while keeping their current proportions. There are also interesting implications for fast device-to-device charging. With batteries able to support very high currents and blazing fast recharge and discharge times, gadgets could charge each other up at super-fast speeds. Although graphene battery technology remains some years away, it’s a tantalizing prospect for future smartphones, gadgets, electric vehicles, and much more.
