对锂离子电池正极材料的探讨与研究

Discussion on Anode Material for Lithium Ion Battery

锂离子电池目前应用广泛,有循环寿命长、无记忆效应、能量密度大、比容量大、电池电压高、体积较小等优点。锂离子电池主要由电解液、隔膜、负极材料和正极材料四大部分构成,其中,正极材料的成本在总成本中所占有的比例较高,大约为40%,锂离子的各项性能指标均与正极材料的好坏有密切关系,所以,锂离子正极材料是组成锂离子电池的核心部分,是非常关键的材料,同时,电池正极材料的性能也可以使锂电池的制作成本降低,对于电动汽车的产业化也有较大的意义。

Lithium ion battery is currently widely used, which has the advantage of long life cycle, no memory effect, high energy density, large specific capacity, high voltage and smaller volume, etc. Lithium ion battery mainly consists of four parts, including electrolyte, membrane, cathode materials and anode materials. Among them, the cost of anode material occupies a higher proportion in the total cost, which is about 40o/40. Each performance index of the lithium ions are related to the quality of anode materials, so anode material is the core part for lithium ion battery, which is very crucial. At the same time, the performance of the battery＇s anode material can also reduce the manufacturing cost of the lithium battery, which has a great significance for the industrialization of electric vehicles.
