发明名称
摘要 Disclosed are an anode material for a secondary battery, a method for producing the same and a secondary battery using the same. The present invention provides the anode material for a secondary battery produced by coating a high-crystallinity core carbonaceous material with a coating carbonaceous material and calcinating the high-crystallinity core carbonaceous material, wherein the anode material has a specific volume of 0.002 cc/g or less. The anode material for a secondary battery of the present invention may be produced by coating a high-crystallinity core carbonaceous material with a coating carbonaceous material and undergoing a predetermined calcination process, and the anode material can have an increased volume ratio of the micropores. Accordingly, the secondary battery of the present invention may be useful to improve charging/discharging capacity and efficiency since sorption of lithium ion in the anode material is improved.
