The Iteration and Development of High-Voltage Tolerant Cathode Materials for Lithium-Ion Batteries

Lithium-ion batteries(LIBs), as one of the most important current electrochemical energy storage technologies, have key performance indicators such as energy density, cycle performance and thermal stability and they are composed of cathodes, anodes,electrolytes and others, among which cathode materials are the core component which are crucial for the energy density and power density of LIBs. However, the limited voltage window and low voltage platform of traditional cathode materials have restricted the energy density of LIBs. Therefore, with the development of some large-scale energy storage systems, the market demand for the high-voltage-tolerant cathode material has grown, and the research on it has become a hot topic. This paper studies the iterative development of different high-voltage-tolerant cathode materials to further understand the cathode materials of lithium-ion batteries.
