镍钴铝三元正极材料研究进展
|
摘要
镍钴铝三元材料可以有效提升正极材料的循环性能和电化学性能,已广泛应用于日本和韩国,并加上特斯拉效应的带动,镍钴铝三元材料将成为未来发展的一大趋势。本文对目前镍钴铝三元材料的制备和改性方法进行了简介,结合文献指出了各方法的优缺点,其中化学共沉淀法是目前制备镍钴铝三元前躯体的普遍方法,而以镍钴铝前驱体为原料在纯氧气氛下烧结是制备三元材料的首选。
The cycle performance and electrochemical properties could be improved effectively through adding cathode material of NCA,which has been widely used in Japan,South Korea and Tesla of US. The research on the ternary cathode material of NCA will become a trend for future development. The preparation and modification methods for the ternary cathode material of NCA were introduced, the features about different methods showed that chemical coprecipitation method was the best suitable way to prepare the precursor of NCA,the sintering of the precursor of NCA under the pure oxygen atmosphere was the best choice for the preparation of the ternary cathode material of NCA.
