PURPOSE: To provide a lithium secondary battery of cylindrical shape, rectangular shape, etc., wherein bending work into an arbitrary shape can be performed in a plate using a molded material to be capable of simply constituting the battery as compared with a conventional method of constituting the battery by arranging a plurality of plates in parallel or in series. CONSTITUTION: In a plate, it is formed of flexible carbonaceous molded material having a structure of dividing a carbonaceous matrix into a fine block condition further inserting a carbon fiber between a plurality of the blocks, and in a nonaqueous electrolytic secondary battery, this plate is used as a negative electrode. |
