几种锂电池正极材料的发展与比较

Development and Comparison of Several Lithium Battery Positive Materials

锂离子电池的性能优劣关键在于其内部的材料性能和结构。锂离子电池的内容材料主要有隔膜、电解质、正极材料以及负极材料,而其中正、负极材料的质量和类型直接关系着锂离子电池所具有的性能以及市场价格。因此,高性能且廉价的正、负极锂离子电池材料成为研究的重点。其中正极材料对电池的性能和价格影响极大,因此,本文重点分析锂电池正极材料。

The key to the performance of lithium ion battery is its internal material properties and structure. The main content materials of lithium ion batteries are separators, electrolytes, cathode materials and anode materials, and the quality and type of cathode materials and anode materials are directly related to the performance and market price of lithium ion batteries. Therefore, high-performance and low-cost cathode and anode lithium ion battery materials have become the focus of research. Among them, the cathode material has a great infuence on the performance and price of the battery. Therefore, this paper focuses on the analysis of the cathode material of the lithium battery.
