摘要: Abstract Cr2O3 is a promising anode material for Li-ion batteries due to its relative low emf value, high Li-storage capacity and cost. However, pristine powder shows poor electrochemical performance electrical conductivity large volume change during cycling. Several strategies are applied improvement, including constructing nanostructure, hetero-atom doping preparing of carbon/Cr2O3 composite with different structures. Carbon coating very effective improving cyclic performance. The mechanism discussed here.
