MANUFACTURING METHOD AND MANUFACTURING APPARATUS OF BATTERY

摘要

PROBLEM TO BE SOLVED: To manufacture a high performance three-dimensional battery having a nest structure.SOLUTION: A separator member 51 is molded into uneven shape copying that of an upstream side carriage 25. A negative electrode active material layer 52 is formed by supplying a negative electrode active material to a recess formed in one main surface of the separator member 51 molded into uneven shape, and a positive electrode active material layer 56 is formed by supplying a positive electrode active material to a recess formed in the other main surface of the separator member 51. Consequently, a high performance three-dimensional battery having a negative electrode 54 and a positive electrode 58 of nest structure is obtained, and the quality and performance of a battery can be enhanced.
