| 摘要 |
Electrochemical cells known as lithium batteries wherein at least one of the anodes, cathodes and/or separator elements thereof contains PVdF homopolymers and/or copolymers and in which calcium carbonate is also incorporated in said battery and, more particularly, in at least one of the anode, cathode and/or separator element thereof. The incorporation of such calcium carbonate acts to reduce or eliminate free acid available which may contribute to the occurrence and/or intensity of runaway exothermic reactions in said battery. Calcium carbonates having a mean particle size of at least about 10 mu m are preferred. |
