Claim Text:
1. A method for producing a composite material for an electrode of a lithium ion battery comprising: precipitating a tin-based material in a presence of a surfactant to form a precipitate; adding a coagulant to coagulate the precipitate to form a deposit of the tin-based material mixed with the surfactant and the coagulant, the coagulant being a carbon-based material; removing the surfactant from the coagulated precipitate to form a first electro-conductive material having pores, the pores containing a decomposable substance; and decomposing the decomposable substance to form on walls of the pores a second electro-conductive material, wherein the second electro-conductive material has a higher conductivity than the first electro-conductive material.
