Abstract
Recently, we have developed a new high power cell. It has the capacity of 5.5 Ah, and has the output power density of 3000 W kgâ1 at 50% state of charge (SOC) and at 25 °C for 5 s discharge basis, and the input power density of 2200 W kgâ1 at the same conditions. The new cells showed much less increase in direct current resistance (DCR) in both the cycle life test and the storage life test than the cells developed before, which consequently implied much longer calendar life than our previous ones developed in 2000.
