【Abstract】 In order to improve the battery life at deep cycling,experiments have been made with regard to the effects of the electrolyte density,grid alloy and electrolyte additive A on the deep cycling performance of posi tive plates.The results show that the electrolyte density has remarkable influence on the deep cycling performance and the special alloy also provides a good effect,but on the interface of grid and active material still exists a passive layer.The electrolye additive A is capable of inhibiting this layer and improves the deep cycling performance of the positive plates.更多还原
