Anode or positive terminal (or plate): The positive plates are also called as anode. The material used for it is lead peroxide (PbO 2). It is a material of dark brown colour. Cathode or negative terminal (or plate): The negative plates are also called as cathode. The material used for the cathode is lead (Pb) and its colour is gray. Electrolyte :

Lead Acid Battery: What''s Inside, Materials, Construction Secrets

Positive Lead Plates: Positive lead plates are made from lead dioxide (PbO2). These plates store positive charge during the battery''s discharge cycle. The chemical reaction on the positive plate involves the oxidation of lead during discharge and its reduction during charging.

Negative and Positive Lead Battery Plates

Understanding Cell and Battery Construction

Older lead-acid batteries were made from cast lead plates onto which a paste was loaded. These plates and separators were then stacked, generally with negative plates on both sides, so there was always one more negative plate than the positive plate. Batteries were often called 7-plate, 9-plate, or as many as 17-plate batteries.
