Poly anionic 硅酸盐材料,表明一个高理论的能力,高安全,环境友好并且便宜,在锂离子电池的下一代用作阴极材料被认为最有希望的候选人之一。这份报纸总结结构和这些材料的表演特征。这些材料的性质上的不同合成方法和锻烧温度的效果被考察。表明各种各样的修正技术的低电导率,差的稳定性, cationic 混乱或其它缺点,和使用的材料例如碳涂层或 compositing,与 mesoporous 材料的元素的做和联合,也被评估。另外,进一步研究话题和电池被讨论的在锂离子使用这些种阴极材料的可能性。
Poly anionic silicate materials, which demonstrate a high theoretical capacity, high security, environmental friendliness and low-cost, are considered one of the most promising candidates for use as cathode materials in the next generation of lithium-ion batteries. This paper summarizes the structure and performance characteristics of these materials. The effects of different synthe- sis methods and calcination temperature on the properties of these materials are reviewed. Materials that demonstrate low conduc- tivity, poor stability, cationic disorder or other drawbacks, and the use of various modification techniques, such as carbon-coating or compositing, elemental doping and combination with mesoporous materials, are evaluated as well. In addition, further research topics and the possibility of using these kinds of cathode materials in lithium-ion batteries are discussed.
