NOVELTY - Anode active material layer containing lithium transition metal oxides as anode active material is cleaned with a cleaning liquid containing an aprotic solvent, hydrohalide(s) and/or solute containing fluorine-containing lithium salt (I). The content of lithium halide adhered to the surface of the anode active material is 300-4000 mu g/1 g of anode active material. Thus, manufacture of anode is carried out.    USE - Manufacture of anode used for lithium ion battery (both claimed). Uses include but are no limited to mobile telephones, portable information terminals, notebook-type personal computers, digital cameras, handheld game machines, electric vehicles, and hybrid vehicles.    ADVANTAGE - The lithium ion battery containing the anode has excellent cycle characteristics, storage characteristics and reliability.    DETAILED DESCRIPTION - Anode active material layer containing lithium transition metal oxides as anode active material is cleaned with a cleaning liquid containing aprotic solvent and/or solute containing fluorine-containing lithium salt of formula: LiZF6-mRm-n (I). The content of lithium halide adhered to the surface of the anode active material is 300-4000 mu g/1 g of anode active material. Thus, manufacture of anode is carried out.    Z=phosphorus, boron, arsenic, or antimony;    R=1-2C perfluoroalkyl;    m=0-3;and    n=0-2.    . (i) When m is 2, Z is boron; (ii) When m is 0, Z is arsenic or antimony: (iii) When n is 0, Z is phosphorus, arsenic or antimony:and (iv) When n is 2, Z is boron. INDEPENDENT CLAIMS are included for the following:    (1) anode which has anode active material layer formed on surface of positive collector; and    (2) lithium ion battery (11) which has separator interposed between anode and cathode, and nonaqueous electrolyte.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic perspective view of lithium ion battery.    Battery case (2)    Anode lead (3)    Cathode lead (4)    Sealing board (5)    Lithium ion battery (11)
