Could lithium batteries be replaced by graphene technology?

The position of the battery in the electric vehicle is equivalent to the human heart, as the power source and the vehicle power source. At present, the mainstream battery of electric vehicles is lithium battery, and the advantages of manufacturing cost are relatively mature. However, lithium batteries also have a fatal weakness, that is, poor safety and the existence of fire risks. In addition, the operating voltage of lithium batteries will vary greatly. These two advantages and disadvantages are also easy to find for this reason. Powered by the battery under. There are many problems in traditional lithium batteries, why not use graphene? In recent years, this concept is a very popular graphene battery. As a new energy source, many experts at home and abroad have studied the battery, so it is still in the research state and officially commercialized. Large-scale processing may be difficult, so it will take some time for graphene technology to replace lithium batteries. It is worth mentioning that businessmen value profit rather than justice. If the lithium battery market is large, the lithium battery repair market will continue to expand. One industry gave birth to another industry. But I think that as new energy vehicles will replace traditional fuel vehicles, pure electric vehicles will become an important direction for new energy vehicles, and lithium batteries may also be replaced by graphene technology, but it will take some time. -Different, the current batch of shipments of artificial graphite, natural graphite, lithium titanate, etc., includes: the cost and capacity of artificial graphite are slightly lower than those of natural graphite, but rely on cycle performance, safety performance, a large proportion of charge and discharge efficiency, electrolyte and intrusive Comprehensive advantages, the delivery rate of cathodes is increasing year by year; Compared with artificial graphite and natural graphite, lithium titanate has better cycle stability and charge-discharge ratio, but its capacity is about 50% of graphite material, and the cost is high. The scope of application is limited. At present, lithium titanate is mainly used for small-batch fast charging buses. Graphitization of the negative electrode material refers to the change from disordered and irregular arrangement of carbon atoms to a regularly arranged hexagonal planar network structure at high temperature, that is, graphite microcrystalline structure. The purpose is to obtain graphite's properties such as high electrical conductivity, high thermal conductivity, corrosion resistance and abrasion resistance. Whether it is artificial graphite or natural graphite, graphitization is an important step in processing cathode materials. At present, carbon anode materials are the most comprehensive and widely used anode materials, including natural graphite, artificial graphite, and mesophase carbon microspheres. Among them, artificial graphite is mainly used for high-capacity automotive power lithium-ion batteries, multiplier batteries and lithium batteries for high-end electronic products, and natural graphite is mainly used for small lithium batteries and lithium batteries for low-end electronic products.
