Abstract:
A cathode active material for a battery cell is described. A protective layer is at least partially applied to the cathode active material, and the protective layer is made of a lithium ion-conducting solid electrolyte layer.

Claim (Index 12):
A cathode active material for a cathode of a lithium ion battery, the cathode active material being provided, at least in part, with a protective layer, wherein the protective layer is made of a lithium ion-conducting solid electrolyte layer that includes at least one of the following compounds:\n a) LiTiCoO 4  (lithium-titanium-cobalt oxide); b) LiPON (lithium phosphorus oxynitride) or Li 3 PO 4  (lithium phosphate); c) LiFePO 4  (lithium iron phosphate); d) Li 4 Ti 5 O 12  (lithium titanate); e) garnets of general formula Li y A 3 B 2 O 12  in a predominantly cubic crystal structure, where A is selected from at least one element of the group La, K, Mg, Ca, Sr, and Ba, B is selected from at least one element of the group Zr, Hf, Nb, Ta, W, In, Sn, Sb, Bi, and Te, and 3<y<7; f) perovskites of general formula Li 3x La 2/3\u2212x TiO 3 , where 2/3\u2265x\u22650; g) compounds of the NASICON type, represented by general formula Li 1+x R x M 2\u2212x (PO 4 ) 3 , where M is selected from at least one element of the group Ti, Ge, and Hf, R is selected from at least one element of the group Al, B, Sn, and Ge, and 0\u2264x<2; h) lithium-ion-conducting sulfidic glasses of general formula x (Li 2 S)\u00b7y (P 2 S 5 )\u00b7z (M n S m ), where M n S m  has the meaning S n S 2 , GeS 2 , B 2 S 3,  or S i S 2 , and x, y, and z may each independently assume a value of 0 to 100, with the condition that x+y+z=100; i) argyrodites of formula Li 6 PS 5 X, where X is selected from Cl, Br, and I; j) polymer electrolytes based on polyethylene oxide (PEO).
