Optimizing the structure of grid can prolong the life of lead-acid battery for electric bicycles.The grid of lead-acid battery for electric bicycles is studied.The grid is analyzed by dissecting the failed batteries.It is found that the bars on the upper of the grid are severely corroded,while the bars near the bottom are basically intact.The structure of grid is designed and optimized to uniform the grid potential and optimize the grid section and strengthen the strength of key corrosion areas,as a result,uniform grid corrosion and grid strength increase are achieved and battery life is prolonged.The cycle number of battery is increased from 428 to 633 after grid optimization.
