铅酸蓄电池正极活性物质活性和失效模式

A Review on Activity and Failure Model of Positive Active Mass in Lead - acid Battery

铅酸蓄电池循环寿命性能衰退通常由正极板性能降低所造成的，正极板的失效与正极活性物质的软化、正极板栅腐蚀和膨胀，以及正极板栅与活性物质界面纯化有关。讨论了正极活性物质的失效模式。

The decline in cycle - life performance of lead - acid batteries is often caused by deterioration of the positive plates. The failure of the positive plates is associated with softening of the positive active material, positive grid corrision and growth, and passivation of the boundary between the positive grid and the active material. The Failure model of the positive active material was discussed.
