working principle

The process of charging and discharging a lead-acid battery is an electrochemical reaction process. When charging, lead sulfate forms lead oxide, and lead oxide is reduced to lead sulfate when discharged. Lead sulphate is a substance that is very easy to crystallize. When the concentration of lead sulphate in the electrolytic solution in the battery is too high, or the static idle time is too long, it will "catch" the group. Forming small crystals, these small crystals then attract the surrounding lead sulfate, forming a large inert crystal like snowballs. When the crystallized lead sulfate is charged, it can not be reduced to lead oxide, but also precipitates on the electrode plate, resulting in a decrease in the working area of the electrode plate. This phenomenon is called vulcanization, which is often called aging. At this time, the battery capacity will gradually decrease until it is unusable.

work environment

As long as it is a lead storage battery, it will be vulcanized during use. However, lead-acid batteries in other fields have a longer life than lead-acid batteries used in electric bicycles because lead-acid batteries for electric bicycles have a working environment that is easier to vulcanize.
