ENERGY STORAGE DEVICE AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A manufacturing method of power storage is provided to increase discharge capacity, and capable of slimming and reducing weight. CONSTITUTION: A manufacturing method of power storage comprises: a step dispersing metal element on current collector(101); a step forming an active material layer(103) from a crystalline silicon layer(103a) including whiskers(113a,113b) by low pressure chemical vapor deposition using deposition gas, which includes silicon as a raw material on the surface of the capacitor; the low pressure chemical vapor deposition operates at the temperature higher than 580°C. The dispersion of the metal element operates by spreading a solution consisting of metal element more than 1000ppm.
