  • Lithium batteries with nano-composite positive electrode material
    Patent number: 10665892
    Abstract: Provided is a positive electrode for a lithium ion battery, the electrode comprising a nano-crystalline layered-layered composite structure of a material having the general formula xLi2MO3(1?x)LiM?O2 in which 0<x<1, where M? is one or more ion with an average oxidation state of three and with at least one ion being Mn or Ni, and where M is one or more ions with an average oxidation state of four. Another aspect provides a positive electrode for a lithium ion battery, the electrode comprising a nano-crystalline layered-spinel composite structure of a material having the general formula xLi2MnO3. (1?x)LiMn2?yMyO4 in which 0.5<x<1.0, 0?y<1, and where M is one or more metal cations. Also provided is the positive electrode which comprises a nano-coating of inert oxide, inert phosphate or inert fluoride on the nano-crystalline composite structure.
