摘要
随着锂离子电池的电容量及循环性能不断得到提高,容量更大、质量更轻、体积更小、厚度更薄、成本更低的锂离子电池不断地推向市场.研究表明,正极材料是锂离子电池性能提高的关键所在,因而研究开发容量大、价格低、无环境污染,且使用安全的正极材料一直是人们关注的热点.本文对锂离子电池正极材料的发展状况进行综述,探讨了生产工艺和掺杂对锂离子电池正极材料性能的影响。
The capacity and cycling performance of lithium ion batteries have been improved a lot.New kinds of batteries with higher capacity,lighter weight,smaller volume and lower cost are continually put into market.New electrode materials and electrolytes with high capacity,low cost,non-toxicity,and safety become the foucus.The historical and recent development of cathodes are reviewed in this paper.And we describe the influence of co-doping technology and method technology to cathode materials.
