The stainless wire 8 is passed through a 2% V 2 O 5 aqueous solution tank 9 to form a V 2 O 5 sol film as the positive electrode active material 3 on the outer periphery of the stainless wire 8. This V 2 O 5 sol film is dried at 65 ° C.
To form a V 2 O 5 xerogel membrane. After that, it passes through the heating furnace 11 and is heated at 200 ° C. here. Next, as a solid electrolyte, a polyphosphazene derivative which is a polymer solid electrolyte is dissolved in 1,2-dimethoxyethane at a concentration of about 40%, and 1 mol / d with respect to the polymer solid electrolyte.
The solution is passed through an electrolyte dissolving tank 12 in which LiClO 4 is dissolved at a concentration of m 3 to form a polymer solid electrolyte membrane outside the V 2 O 5 xerogel membrane. Thereafter, vacuum drying is performed on the dry matter 13 at 60 ° C. After drying, the powder passes through the lithium powder chamber 14 to form a lithium powder layer as a negative electrode active material outside the polymer solid electrolyte membrane.
