ELECTRODE COMPOSITE BODY, METHOD OF MANUFACTURING ELECTRODE COMPOSITE BODY, AND LITHIUM BATTERY

摘要

An electrode composite body (4) includes: a porous active material molded body (2) including active material particles (21) of a lithium composite oxide (e.g. LiCoO 2 ) impregnated by a first inorganic solid electrolyte (3) and a second inorganic solid electrolyte (5) wherein the second inorganic solid electrolyte (5) is amorphous and has a composition which is different from the one of the first inorganic solid electrolyte, and which contains boron as a constituent element (e.g. the lithium borate Li 3 BO 3 ). Corresponding manufacturing methods wherein the first and second inorganic solid electrolytes are supplied to the porous active material molded body either separately or as a mixture are also provided.
