A lithium electrochemical cell of either a primary or a secondary chemistry activated with an electrolyte having a cyclic carbonate of a ring size equal to or larger than a six-member ring is described. The cyclic carbonate helps to make the anode passivation film ionically conductive to thereby eliminate voltage delay during pulse discharge and to reduce Rdc. Such a cell is particularly well suited for powering an implantable medical device, such as a cardiac defibrillator.

碳酸盐有助于使阳极钝化膜具有离子导电性,从而消除脉冲放电过程中的电压延迟并降低 Rdc。这种电池特别适合为植入式医疗设备(如心脏除颤器)供电。
