Secondly, the corrosion and softening of the positive grid remain major issues. During the charging process of the lead acid battery, the lead dioxide positive electrode is polarized to a higher potential, causing the lead alloy positive grid, as the main body, to oxidize to lead oxide.
The active masses of the negative and positive electrodes were electrochemically prepared on lead plates, a process still used even today. Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte.
The basic electrochemistry of the lead-acid battery is very well understood. All lead-acid batteries contain a porous Pb (negative) electrode, a porous PbO 2 (positive) electrode and sulfuric acid electrolyte. The primary discharge reactions of the lead-acid battery are as follows:
