 @Premlis® realized the maximum operating voltage of 4.0 V with an effective energy density of 15 Wh/kg (see diagram below).
@We achieved a capacity maintaining rate of 80% or more at 6000 cycles (equivalent to approximately 70,000 cycles at room temperature) at 60Ž as a charge and discharge characteristic. We also achieved a voltage reduction rate of 1.7% (for 72 hours at room temperature) as a self-discharge characteristic.
