高能量密度锂离子电池层状锰基正极材料研究进展
Research progress of layered Mn-based cathode materials for high-energy-density lithium-ion batteries
摘要
Abstract
Layered Mn-based series Li[Lix(MnM)1-x]O2(M=Ni, Co, Cr,…) due to its much higher capacity is one of the very promising candidates of cathodes, which has become a research hotspot recently and attracted more and more attention. Especially, with the aid of advanced characterization techniques including in-situ analysis, studies on the complex structure and high-capacity delivering mechanism of the series have achieved significant progress. In the paper, the structural characterization and charge-discharge behavior of the high-energy density layered cathode were briefly introduced. Study progresses on the voltage degradation, interface/surface variation during cycling and performance improvements of Li[Lix(MnM)1-x]O2 were reviewed in detail particularly in view of its exiting issues. Furthermore, the challenges and prospects in the high-energy density layered cathode materials were also discussed herein.关键词
