ULTIMO cells neither burn nor explode in any of overcharge, overdischarge, and external short-circuit tests, exhibiting excellent safety.
After experiencing a charge-discharge operation of 200,000 cycles, they do not exhibit noticeable deterioration.
(Test condition) Charge: CC 100 A at 3.8 V; discharge: CC 100 A at 2.2 V, both without intermission
CLQ1100S1A (laminate cell 1100F）
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.
After 1,000 hours in operation, they do not exhibit noticeable deterioration.
(Test condition) Applied voltage: 3.8 V in an ambient temperature of 70˚C
