  • Patent number: 9496066
    Abstract: The present application discloses boron-doped lithium rich manganese based materials for cathodes of lithium ion batteries. The disclosed cathode materials can be prepared by co-precipitation and sol-gel methods. The chemical formula of this cathode material is Li[LiaMnbCocNidBx]O2 (a+b+c+d+x=1, a, b, x>0, c?0, d?0, c+d>0). Lithium ion batteries using these cathode materials show impressive improvements in performance and increased tap density at low level of boron doping.
