6LR61 battery anode materials: research on graphite materials and carbon anode materials
6LR61 battery anode materials: research on graphite materials and carbon anode materials. In the past few years, driven by national policies, new energy vehicles have developed rapidly, domestic power battery companies have also significantly expanded production, and the demand for lithium battery anode materials has greatly increased. Carbon-based anode materials have the advantages of abundant raw materials, low cost, large reversible capacity and good rate performance, and have attracted the attention of experts and scholars at home and abroad. This article will discuss the research on graphite materials and carbon anode materials.
Research on graphite materials and carbon anode materials
Existing domestic anode products are mainly carbon materials and non-carbon materials. Carbon materials can be divided into graphite carbon materials and amorphous carbon materials. The most commonly used graphite carbon materials are natural graphite and artificial graphite; non-carbon materials Mainly include tin-based materials, silicon-based materials, nitrides, and titanium-based materials, of which silicon-based materials and titanium-based materials have a small number of applications in the market.
Carbon anode materials that have been studied so far include graphitized carbon and non-graphitized carbon. Among them, graphite is considered to be an ideal anode material in current 6LR61 battery applications due to its low charge-discharge voltage platform, high cycle stability and low cost. At present, research on the modification of natural graphite has made certain progress and has been commercialized.
●Graphite materials
Graphite is a layered crystal, formed by stacking countless graphite sheets under the action of van der Waals forces. Graphite contains two different surfaces. The plane between the layers is the base plane, and the surface perpendicular to the base plane is the prism. The prism includes zigzag surface and rocking chair surface. Oxygen-containing functional groups are usually present on the prism surface.
The coating state of the graphite material itself will also affect the performance of the negative electrode. It is generally coated with some amorphous carbon materials to improve the interface impedance of the negative electrode and improve low temperature and cycle performance. As the energy density of batteries increases, the capacity utilization rate of graphite anodes gradually approaches the theoretical value, and the compaction will become higher and higher, which requires that the stability of graphite anodes also be improved. Currently, doping Hybridization and coating are still a mainstream method of treatment. After modification, the structure and surface state of the graphite anode can be protected during the cycle, and the stability of the cycle is enhanced.
●Carbon anode material
There are many types of carbon materials, and their crystalline forms include diamond, graphite, fullerene, carbon nanotubes, etc. The first commercial application of carbon negative electrodes in lithium-ion batteries was non-graphitized carbon materials. From 1993 to 1994, Panasonic Battery Industry Co., Ltd. After Sanyo Electric Company entered the market, it adopted graphitized carbon materials with higher capacity. From then on, competition between the two major types of carbon materials began.
Although there are no accurate statistical data on the actual application of the two types of carbon negative electrodes, some experts estimate that more than 75% of the negative electrode materials in currently commercially available lithium-ion batteries use graphite-based carbon negative electrode materials. Although there are currently many promising non-carbon anodes that may be used in the field of lithium-ion batteries, they will still face many challenges. Therefore, the improvement of 6LR61 battery capacity will still rely on carbon for a long time to come. Development and improvement of negative electrode materials.
At present, the global anode market has stabilized, and demand has grown steadily every year. However, rising costs and prices, an increase in anode companies, and intensified industry competition have led to a compression of the overall profits of the industry. It is expected that global anode material output will grow faster in the next few years. will gradually slow down, and the development and application of new materials and new technologies will be the key to breaking through the bottleneck of the industry.
