キや、工程上のトラブルの原因となっていた。Problems to be Solved by the Invention In the above manufacturing method, as batteries become smaller and thinner, when a thin non-woven fabric or porous film separator is used as a separator, the amount of electrolyte retained decreases. As a precaution, when inserting the positive electrode or caulking the cap, free electrolyte is scattered, causing the electrolytes ti and n in the battery to become unbalanced, causing variations in discharge characteristics and troubles in the process.

を目的とするものである。The present invention eliminates the above-mentioned conventional problems and stabilizes the discharge characteristics and process by adopting a manufacturing method that does not cause electrolyte scattering and is suitable for making batteries smaller and thinner. This is the purpose.

としたものである。Means for Solving the Problem The present invention aims to solve this problem by inserting a cup-shaped separator into a sealing plate to which a negative electrode active material is crimped, and then inserting a positive electrode assembly with a hole in the center. In this manufacturing method, a battery is constructed by pouring an electrolytic solution into the positive electrode mixture, placing a ring having an angular cross-section, and then pouring an electrolyte into the surface of the positive electrode mixture, including the holes.

間が短くなる。Function: According to this manufacturing method, by injecting electrolyte into the holes of the positive electrode mixture, the electrolyte quickly enters the separator surface and leaks out of the separator, thereby lowering the resistance of the separator and increasing the strength of the positive electrode. The holes increase the surface area, increasing the amount of electrolyte absorbed by the positive electrode mixture and shortening the absorption time.
さらに、浮遊の電解液がなくなり、電解液の飛散がなく
工程が安定化し、電池内部の電解液量が一定化するため
に放電特性が安定化する。Furthermore, there is no floating electrolyte, the process is stabilized because there is no scattering of the electrolyte, and the amount of electrolyte inside the battery becomes constant, which stabilizes the discharge characteristics.
