PROBLEM TO BE SOLVED: To provide a composition for a battery electrode which improves freedom in composition design of an electrode for a battery, improves productivity and improves output properties in addition to satisfactory cycle properties, and an electrode for a battery using the same.SOLUTION: A composition for a battery electrode contains at least an active material, fibrous polysaccharide with a carboxyl group, and a dispersant. An electrode for a battery and a manufacturing method thereof include the steps of coating the composition for the battery electrode and drying the composition for the battery electrode. The number of moles contained in the carboxyl group or TEMPO oxidized cellulose into which carboxylate is introduced partially or with respect to a cellulose weight and further a fiber width and a fiber length of cellulose fibers obtained by defibrating cellulose are specified. |
