摘要： A negative electrode carbon material for a lithium ion secondary battery manufactured by calcinating a rice starch portion obtained by removing the pericarp and testa from unpolished rice and a method for manufacturing the same. The rice starch portion is preferably middle-grade white bran or high-grade white bran each obtained when unpolished rice is polished. The above negative electrode carbon material preferably has a relatively broad peak at a 2θ of 40 to 50° and a sharp peak at a 2θ of 42 to 44° in its powder X-ray (CuKa,) diffraction. According to the present invention, a negative electrode carbon material for a lithium ion secondary battery which has the same quality as the prior art product can be manufactured at a low cost by making effective use of middle-grade white bran or high-grade white bran of rice.
