Charge-discharge characteristics improvement through optimization of voltage range for LiNiCoMnO2 electrode for high energy density lithium-ion batteries

The development of suitable electrode materials for lithium ion batteries (LIBs) to enhance the performance of LIBs in order to meet increasingly demand globally is one of the challenges. Thus, for almost three decades since 1980, continuous study for high performance LIBs electrode has been done. I...
