Strategies enhancing the electrochemical performance of NMC811 high energy electrodes for xEV applications

摘要

Layered oxide cathodes are among the most promising candidates meeting future requirements for Li-ion batteries for application in electric drives.Lithium nickel manganese cobalt oxides,NMC,as one of the most common representatives,is therefore under constant investigations,whereas most of the recent studies focus on low Co [1] and Ni-rich NMCs such as NMC622 or further NMC811.Besides cost reduction,these compounds promise higher cut-off voltages and increased energy densities.
