摘要
锂离子电池的多样化和广泛应用,迫切要求开发具有高能量密度的新一代锂离子电池,这在很大程度上取决于正极材料。近年来,Li_(2)MSiO_(4)(M=Fe,Co,Mn...)以其热稳定性好、储量高、成本低和环境友好性而受到广泛关注。综述了Li_(2)CoSiO_(4)正极材料在相转变结构、合成方法及电化学性能改进技术等方面的研究进展。
With the diversification and wide application of lithium-ion batteries,it is urgent to develop a new generation of lithium-ion batteries with high energy density,which largely depends on the cathode materials.In recent years,Li_(2)MSiO_(4)(M=Fe,Co,Mn...)has been widely concerned for its high thermal stability,high reserves,low cost and environmental friendliness.This review focuses on the research progress of Li_(2)CoSiO_(4) cathode materials in phase transition structure,synthesis method and electrochemical performance improvement technology.
