Abstract
Disclosed is an electrode for secondary battery, which comprises lithium or an alkali metal composed mainly of lithium doped as the active substance in a carrier composed of a mixture of a carbonaceous material satisfying the following conditions (A) and an organic polymer having ion conductivity of lithium. (A) a carbonaceous material with a hydrogen/carbon (H/C) atomic ratio of less than 0.15, a spacing (d.sub.002) of the (002) plane according to the X-ray wide angle diffraction method of 3.37 to 3.75 .ANG. and a crystallite size in the c-axis direction (Lc) of 5 .ANG. or more.
