The lead-acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals of …

Lithium-ion vs. lead acid batteries: How do they compare
Lead Acid Batteries. The primary components of these marine batteries are lead and acid. Experts typically use flooded lead-acid batteries containing sulphuric acid and distilled water mixture. However, it requires them to add water frequently. The only downside is their weight. Lead-acid batteries weigh far more than lithium batteries.
The electrochemical equivalent weights of the active materials in a lead–acid cell per Ah are 3.866 g Pb Ah⁻¹ (for the Pb/PbSO4 electrode) and 4.463 g PbO2 Ah⁻¹ (for the PbO2/PbSO4 electrode).
It is found that a significant amount of literature is focused on the inclusion of additives on the negative active material (NAM) electrode when compared to the positive active material (PAM) electrode. The weight percent (wt.%) and particle size of carbon additives was found to influence the cycle life of the batteries.
