Summary:

The invention provides a nano-chemical composite cathode lithium supplement slurry, wherein the composite cathode lithium supplement slurry comprises a composite lithium supplement material, and the composite lithium supplement material comprises: an organic lithium supplement material and a catalyst, wherein the organic lithium supplement material is a carbon oxide of lithium, and the catalyst is a transition metal carbide; The catalyst is obtained by high-temperature carbonization synthesis, and the morphology is nanoparticle, nanowire, or nanosheet, and the particle size size is nanoscale. The present invention effectively designs the structure of the catalyst and controls the particle size of the catalyst to the nanometer level, so that the contact between the catalyst and the lithium supplement material is good, so that the decomposition potential of the organic lithium supplement material into active lithium can be effectively reduced while improving the charging capacity of the battery.
