Lead-acid batteries are mainly composed of positive and negative plate groups, separators, containers and electrolyte. (1) Polar plate. The positive and negative plates of lead-acid batteries are made of pure lead, and effective substances are directly formed on them; some pole plates are made of lead-nickel alloy grids and coated with effective substances. The effective …
