LiNi0.5Co0.5O2正极材料制备方法的改进

Getting LiNi0.5Co0.5O2 cathode material with the use of sol-gel method, when testing electrode, we smooth the traditional thin aluminum Uniform coating film to improve the preparation method, with the use of thick aluminum and polished fine sand paper to rough the surface uniformity, and uniformly coating, so that adhesion can be increased so as to effectively improve the charge-discharge process, the material particle between loose and fall off, resulting in increased internal resistance, capacity to reduce defects and improve the overall performance of the battery.
