Why does graphene battery not replace lithium battery?

　　Graphene battery has higher strength, better toughness, light weight and excellent conductivity. As early as a few years later, Huawei announced its fast charging technology to charge the 3000mAh graphene battery, which can charge nearly half of its power in only 5 minutes. It can be seen that graphene battery is not only suitable for new energy vehicles, but also widely used in the field of mobile phones in China. However, it is still in the experimental stage, and there is still a long way to go for market application. Graphene has more advantages than traditional batteries. Its service life is twice that of lithium battery and four times that of hydrogenated battery. In terms of weight, it weighs about half as much as a traditional battery. As far as the charging rate is concerned. Graphene batteries can be improved dozens or even hundreds of times. In fact, graphene batteries are not available in our market, for example, in some high-end medical devices. However, these graphene batteries are not the pure graphene batteries we expected. They are only doped with some graphene related technologies based on lithium batteries. Compared with the traditional lithium battery, it brings only a little performance improvement. In addition, the cost of graphene is very high, and its manufacturing process is also very high. It still needs a big step to reach the mass production stage. With such a high cost and a series of performance improvements, some manufacturers are naturally not interested in graphene batteries. At present, graphene batteries are not mature and show no obvious advantages compared with lithium batteries, so the replacement era of lithium batteries may not come so early. Graphene battery is considered to be one of the more potential materials in the future, but at present, its foam composition is greater than its practical application value. Many factors have hindered the popularity of this material. Mass production and costs are major obstacles. Graphene battery has a long way to go to replace lithium battery in the short term.
