Abstract
A method for producing a non-graphitizable carbon material includes providing a raw material of a non-graphitizable carbon material. The raw material is cross-linked to obtain a cross-linked product. The cross-linked product is infusibilized to obtain an infusibilized product. The infusibilized product is baked to obtain the non-graphitizable carbon material. A mechanochemical treatment is performed on the cross-linked product or the infusibilized product.
