Latest Patents

Nakanose’s listed patents address precision and reliability in battery production.

“Spiral Electrode Group Winding Method and Device and Battery Using Them” describes a process for winding continuous anode plates, cathode plates, and separators around a turnable core. Edge-position detection and a sequence of chucks help correct and hold the electrode plates as they are fed to the core, reducing alignment deviations during winding. The invention also describes a generally hexagonal cross-section for the winding core, intended to improve the flatness of electrode groups when arranged side by side.

“Cylindrical Battery Assembling Apparatus” describes equipment for guiding a seal plate into a cylindrical battery casing. A tapered guide sleeve and coordinated upper and lower spindles direct the inclined seal plate toward the casing opening, supporting controlled assembly of the battery.
