用有限元方法分析了铅酸蓄电池用三维网络碳化硅板栅和极板内电流的分布. 结果表明, 与常规板栅相比, 三维网络碳化硅板栅与极板内电流分布比较均匀. 极耳的形状和位置对板栅和极板内电流分布的影响很大, 当极耳具有夹心结构时, 电流分布的均匀性有非常明显的改善, 尤其是在厚度方向具有类似三明治的极耳夹心结构时, 板栅和极板内的电流分布极为均匀, 且电流的数值比较小.
A finite element analysis of current distribution over three-dimensional networks grid and plate in lead--acid batteries is presented. Calculated results showed that the current distribution over three--dimensional networks is more uniform than that over general grid and plate of lead--acid battery. The effects of shape and locating position on current distribution over three-dimensional networks were great. Calculated results showed that a more uniform electrical current distribution over 3--D networks can be obtained when the tabs of plate are interlayer, especially when the tab interlayer is in thickness direction and similar to sandwich structure.
