摘要： Provided is 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 (CuKα) 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.

摘要： The bran has been less usable and have not been treated as industrial resources. The present invention is a method for producing a porous carbon material product and a hard porous carbon material product which have wide variety of functionalities utilizing such bran which is burned and carbonized stably. The method according to the present invention comprises of the steps of kneading bran with a thermosetting resin and an adequate amount of a solution including an adhesive paste or water, the bran is such as rice bran or wheat bran adjusted grain size; granulating the bran kneaded to predetermined grain size or less; molding the bran granulated in a metal mold by pressurizing and degassing to be a mold; burning and carbonizing the mold detached from the metal mold by heating to desired final burning temperature at a predetermined rate under inactive gas atmosphere or under vacuum; and cooling the mold from the final burning temperature to normal temperature at a predetermined rate.
