ULTIMO Prismatic cell

ULTIMO is an electricity storage device with both high energy density and high power density features, and can be charged and discharged at a large current. Ensuring high safety, ULTIMO cells feature enhanced repeated charge and discharge characteristics, little self-discharge, and wider working temperature ranges.
They can be used for various purposes such as backup, storage, peak assist, and energy regeneration, contributing to stabilization of power supply, electricity storage, electricity economization, electricity conservation, and the like.
We have adopted the world’s first prismatic-can structure for a lithium ion capacitor configuration.
We provide products that excel in heat radiation efficiency and ease of implementation in comparison with common cylindrical type.
