Latest Patents

One of Tsurutani's latest patents is a closure assembly for sealed batteries. This innovative design incorporates explosion-proof features, ensuring safety during operation. The assembly consists of a metal plate with a hole, an insulating resin sheet, a metal thin sheet, an insulating sheet with an air hole, a metal guide plate, and a metal cap, all arranged within an insulating gasket. The metal plate and guide plate are electrically connected, allowing for safe operation. In the event of pressure build-up within the battery, the insulating resin sheet expands and ruptures, leading to the breakage of a narrow part in the metal thin sheet, effectively cutting off the electric current.

Another significant patent is for a sealed battery and its manufacturing method. This design includes a metal reinforcing plate welded close to the opening inside the battery case. A plastic insulation gasket and a sealing member with an anti-explosion mechanism are mounted sequentially on the metal plate. This arrangement maximizes battery capacity by eliminating unnecessary space, resulting in a highly reliable sealed battery construction that prevents leakage.
