Study on the acid soaking technology of pure lead plate of lead-acid battery
This paper explores the feasibility of using positive plate soaking technology to solve the problem of dendrite short circuit in pure lead thin plate lead-acid batteries by studying positive plates with different soaking time.The results show that a layer of dense lead sulfate is formed on the surface of the positive plate after soaking in sulfuric acid solution,which reduces the heat generated during the initial soaking of the battery,slows down the penetration rate of sulfuric acid into the inside of the plate,reduces the reaction rate between sulfuric acid and the substances inside the plate,thus reducing the temperature during the soaking process of the battery and effectively inhibiting the problem of dendrite short circuit in the battery.The battery is assembled using a positive plate soaked in sulfuric acid solution for 5～15 s,and the cycling performance of the battery is obviously improved by matching the formation process with reverse charging.
