    • A cathode material featuring PVM for use in rechargeable electrochemical cells. It has been discovered that the polymer backbone of PVM, which consists solely of carbon atoms, is not subject to scission during repeated charge-discharge cycles, such that the cathode material remains substantially insoluble in standard liquid electrolytes. As a result, cells containing PVM as the cathode material and liquid electrolyte are genuinely electrochemically reversible. The use of PVM overcomes the problems associated with organosulfides of the background art, with which dissolution of anions in the liquid electrolyte during discharging results in migration from the cathode and contamination of the anode/electrolyte surface and ultimately leads to degradation of the electrolyte and/or deterioration of the anode-electrolyte interface.
    • 一种用于可再充电电化学电池的PVM阴极材料。 已经发现,仅由碳原子组成的PVM的聚合物骨架在重复的充放电循环期间不会发生断裂,使得阴极材料基本上不溶于标准液体电解质。 结果,包含PVM作为阴极材料的电池和液体电解质真正地在电化学上是可逆的。 PVM的使用克服了背景技术中与有机硫化物有关的问题,阴离子在放电过程中溶解在液体电解质中会导致阴极迁移和阳极/电解质表面的污染,并最终导致电解质和/ 或阳极 - 电解质界面的劣化。
