Characteristics of graphene batteries

by:GREEN TECH     2021-03-15
Electric vehicles have always been a unique scenery in cities and towns. Although the conditions of use are very low, they are also subject to many restrictions. Electric vehicle batteries are a key factor that seriously affects the use of electric vehicles. Traditional lithium batteries have always been criticized for both their service life and charging time. However, the new type of graphene battery is significantly better than it in all aspects, so graphene Can batteries be used as electric vehicle batteries? Can graphene batteries replace lithium batteries in electric vehicles? From the perspective of use alone, graphene batteries are fully qualified for the role played by lithium batteries in electric vehicles. They have a larger storage capacity and a faster-charging speed and are better than lithium batteries at high temperatures. To be durable. Therefore, there is no problem with graphene batteries as electric vehicle batteries. Although graphene batteries are better than lithium batteries in many theoretical performances, they still cannot replace lithium batteries in electric vehicles due to various factors. First of all, the cost of graphene batteries is extremely high. Highly conductive graphene used as a raw material currently sells for up to 600 yuan per gram. Graphene batteries called 'black gold' are mostly used in aerospace and mobile devices. People-friendly electric cars can only be amazed by it. Secondly, the manufacturing process of graphene batteries is still not mature enough. It is currently only in the laboratory stage and cannot reach the point of mass production. Graphene batteries are difficult to achieve in the electric vehicle market in the short to medium term. In addition, compared to graphene batteries, lithium batteries, which are the crystallization of battery development, still have many advantages. Both the market and technology are more perfect. Graphene batteries are more likely to be integrated into lithium batteries with new technology. Promote the process of battery revolution. In general, although graphene batteries far outperform traditional lithium batteries in terms of performance, they still cannot replace lithium batteries in the application of electric vehicle batteries. Nevertheless, the research and development of graphene batteries is still going on. The simplification of the process and the optimization of materials are the focus, and it may not be a dream to use it as an electric vehicle battery in the future.
