Laminate Cells

ULTIMO is an electricity storage device with both high energy density and high power density features and can be charged and discharged at a high current. Ensuring a high degree of safety and excellent performance through life, they feature little self-discharge and have a wide operation temperature range.

ULTIMO cells can be used in mobile applications such as energy recuperation in cars, buses, light rail vehicles (LRV), trams and other commercial vehicles. They also contribute to performance improvement of stationary systems such as backup storage, peak assist, power quality, electricity storage, and the like.

Laminate or pouch type cells are thin, lightweight, compact, safe in use and show excellent thermal behavior, resulting in a wide spectrum of applications.

Cycle life performance 

Cycle life performance

Test condition: Charge: CC 100 A to 3.8 V; discharge: CC 100 A to 2.2 V; no rest times between charging and discharging, CLQ1100S1A (laminate cell 1100F)

After a charge-discharge operation of over 1.5 million cycles at 100% of the operation Voltage range (100% DOD), the cell capacity retention is still higher than 90%.

An ULTIMO cell can be operated at a cell voltage higher than that of an electric double layer capacitor and has excellent high temperature durability. This characteristic is achieved by a design that uses the pre-doping process to lower the potential of the negative electrode and thereby to restrict an increase in the potential of the positive electrode; at the same time, this suppresses the deterioration of the negative electrode, resulting in high durability even after repetition of charge-discharge cycles.
