Abstract:

The lithium-riched manganese based cathode material is one of the most competitive next-generation cathode material to relapce layered lithium mixed cobalt/nickel/manganese oxides cathode materials. This paper uses the PatSnap platform to search the patents ralated to lithium-rich manganese-based cathode materials worldwide, collects the patent data in the field of lithium-rich manganese-based cathode materials and gets the analysis sample after re-processing; gives a general overview of the sample patent, the patent owner and inventor analysis, technical analysis, patent mp and patent high-frequency keywords, analyzes the present situation of the application of lithium-rich manganese-based cathode materials,the key technical distributioon field, the value of patent and so on, and dorecasts its development direction.
