Research Progress on Preparation of LiNi_(0.5)Mn_(1.5)O_4 as Cathode Materials for Lithium Ion Battery

近年来随着电动汽车等高功率密度、高比能量的极大需求,传统的正极材料已经不能满足这些要求。且由于LiNi_(0.5)Mn_(1.5)O_4具有高电压和高能量密度等优点,该材料的研究也逐渐增多,在此基础上文章阐述了LiNi_(0.5)Mn_(1.5)O_4材料合成方法的研究进展。不同制备方法得到的材料电化学性能也有所差异,根据所需产品的性能采用相应的制备方法并对其进行改进也是今后研究的重要课题。

With electric vehicles, high power density and high special energy demand in recent years, the traditional lithium ion battery cathode materials can not meet these requirements. Moreover LiNi_（0.5）Mn_（1.5）O_4 with high voltage and high energy density, etc., to study the material has become a hot topic cathode material at this stage, on the basis; this paper summarizes the synthesis method on LiNi_（0.5）Mn_（1.5）O_4 materials. Electrochemical performance of different methods of preparation are also different, use the appropriate method depending on the performance required for the preparation of the product and to improve it is an important topic for future research.
