摘要: The effects of cycle potential window on electrochemical behaviors, structural characteristics, and surface changes in Li[Ni0.133Li0.2Co0.133Mn0.533]O2 (or 0.5Li2MnO3·0.5Li(Co0.333Ni0.333Mn0.333)O2) lithium-ion battery were investigated. Two flat charge plateaus, ~3.9 ~4.5 V, are observed the initial curves cells. Sharp specific capacity columbic efficiency presented at V during first cycle. XRD peaks show an obvious shift with increase cutoff potential. When is above 4.4 performance decreases potentials. A film composition C O elements cycled composite particle.
