Current distribution on the electrode in 3-D networks lead-acid batteries

摘要

The current distribution on the grid and plate in lead-acid batteries was determined mathematically by using the equivalent circuit method. The grids used in lead-acid batteries are the general lead grids and the 3-D networks grids, respectively. The calculated current distribution on the grid and plate of three-dimension networks lead-acid battery is more uniform than that of general lead-acid battery. To make the current distribution nearly uniform, extended current tabs located between two plate electrodes were proposed, and a sandwich networks plate was formed.
