This makes it have unique properties, including excellent electrical and thermal conductivity, high flexibility, high strength, and low weight. Electrical and heat conductivity is superior to copper, which is used as the most common conductor.The problem is the cost of manufacture. This is what holding the Graphene batteries. These can be used as supercapacitors.Graphene batteries can be made slimmer, has very fast charging and much safer. Also it can be used to make batteries with higher capacity. For eg Li-ion stores up to 180Wh of energy per kilogram while Graphene can store up to 1,000Wh per kilogram.Tesla was interested in this with Samsung technology but haven't heard much lately.Li-ion batteries can use graphene to enhance cathode conductor performance. These are known as graphene-metal oxide hybrids.Also smartphone battery manufacturers are investing in research. Huawei was announcing to have their P40 Pro with a Graphene battery, but I don't think that happened</blockquote>
