1. a preparation method for anode plate for lithium ionic cell, it comprises the following steps:

  • It is coated with one layer of cladding material at alloy material particle surface;

    The first solvent mix homogeneously by a certain percentage formation cathode size of the cladding alloy material of material, material with carbon element, conductive agent, binding agent, insoluble cladding material will be coated with, cathode size is coated uniformly on negative current collector, after super-dry, compacting, forms pending negative plate;

    AndBeing cleaned in the second solvent of soluble cladding material by pending negative plate, the cladding material being coated with by alloy material surface makes negative plate through super-dry after dissolving.
