Enhanced rate and high-temperature performance of La0.7Sr0.3MnO3-coated LiNi0.5Mn1.5O4 cathode materials for lithium ion battery

► With La0.7Sr0.3MnO3-coating the rate performance and thermal storage of LiNi0.5Mn1.5O4 is improved. ► High conductive La0.7Sr0.3MnO3 is responsible for the improved performance at high-temperature. ► La0.7Sr0.3MnO3 layer suppresses the Mn dissolution and reduce the charge-transfer resistance.
