Large Prismatic Battery Parts

We produce the battery parts for large prismatic batteries used in electric vehicles (xEV) and the energy storage system (ESS), and we produce the parts manufactured conforming to various specifications.
We designed the multi-tab type to prevent the battery leakage through ultra-precision welding and increase the capacity, and maximized the space for holding the electrolyte.
In order to increase the output of batteries for electric vehicles (xEV), we are developing an integrated molding type, and for this purpose we have developed and hold the technology of chemical surface treatment and insert injection.
