摘要： PROBLEM TO BE SOLVED: To solve problems that in the case silicon oxide is used as a negative electrode of a lithium ion secondary battery, individual columnar particles are peeled off from a current collector, and charge/discharge capacity is reduced if charge/discharge cycle is repeated.
SOLUTION: This is a manufacturing method of forming an active material layer composed of silicon oxide having a chemical composition expressed by SiO
x (0.05≤x≤0.3) on the sheet state current collector having conductivity by a vapor-deposition method, wherein a period of accumulating the active material on the current collector and a period of suspending the accumulation with the silicon as a vapor-deposition source in an atmosphere containing oxygen are alternately installed. By this, the negative electrode can be manufactured by a device of which the film forming rate is fast and which is comparatively simple and convenient. Moreover, the negative electrode obtained by this manufacturing method has an insular structure in which the columnar particles are aggregated in a plurality of numbers on the current collector, and even if the charge/discharge cycle is repeated, capacity deterioration derived from peeling-off from the current collector becomes reducible.
