  • Composite anode material including nickel oxide and the method for preparing the same
    Patent number: 10135065
    Abstract: The present invention provides a composite anode material including nickel oxide, a method for preparing the composite anode material, and a lithium ion battery using the composite anode material. The composite anode material has a core-shell structure, the inner core is an inert core comprising a non-active material, and the outer shell comprises an anode active material of nickel oxide. The composite anode material with core-shell structure in the present invention overcomes the problem of volume changing and chalking of nickel oxide during charging/discharging and obtains a better cycle performance and rate performance.
