摘　　要：为了提高铅酸电池的能量密度和寿命,发展轻量化的板栅以取代比重大的铅板栅,具有重要的实际意义。铅酸电池用轻量化板栅的失效主要是由板栅在电化学环境下腐蚀所引起的。因此,板栅在酸性条件下抗电化学腐蚀的能力对铅酸电池的性能和寿命有很大的影响。笔者总结了轻质金属板栅、轻质合金板栅和铅炭板栅的发展状况,以及其用于铅酸电池时的失效机理,并论述了板栅失效对铅酸电池机械强度和寿命的影响。为了促进耐腐蚀的轻量化板栅的研发,还提出了几个未来可能的研发方向。In order to improve the energy density and cycle-life of lead-acid batteries,it is of great practical significance to develop lightweight grids to replace heavy lead grids.Failure of lightweight grids in lead-acid batteries is mainly caused by corrosion of the grids in an electrochemical environment.The ability of the grid to resist electrochemical corrosion under acidic conditions has a great impact on the performance and life of lead-acid batteries.This article reviews the development of lightweight metal grids,lightweight alloy grids,and carbon-lead grids,and their failure mechanisms when used in lead-acid batteries and analyzes the effects of grid failure on the mechanical strength and cycle-life of lead-acid batteries.In order to promote the development of lightweight corrosion-resistant grids,this article also proposes several possible future research and development directions.
