This chapter reviews of the influence of additives to the pastes for positive and negative plates on the processes of plate manufacture and on the performance of lead–acid batteries. The performance of the lead–acid battery depends on the surface of the active materials of the two types of electrodes.
The transformation of the PAM is responsible for the utilization of the active material and the structural integrity of the plate. The failure reasons and the improving methods of the positive electrode battery are shown in Fig. 1.
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 test battery consists of one positive electrode and two negative electrodes. The negative electrodes were commercial negative plates with a size of 4 cm × 6.8 cm. The active material mass of each negative plate was 18 g, so the performance of the test battery was only limited by the positive electrode.
In order to solve the positive electrode problems, numerous researchers have been doing a lot of research to improve the performance of the battery positive electrode. It is found that the overall performance of the battery can be greatly improved with the use of suitable PAM additives.
Such applications include automotive starting lighting and ignition (SLI) and battery-powered uninterruptable power supplies (UPS). Lead acid battery cell consists of spongy lead as the negative active material, lead dioxide as the positive active material, immersed in diluted sulfuric acid electrolyte, with lead as the current collector:

The positive electrode is one of the key and necessary components in a lead-acid battery. The electrochemical reactions (charge and discharge) at the positive electrode are the conversion between PbO2 and PbSO4 by a two-electron transfer process. To facilitate this conversion and achieve high performance, certain technical requirements have to be met, as described in the …

It is essential for the lead dioxide to have a rather low electrical resistivity, i.e., ∼1 × 10 −6 Ω m. Whereas this is the figure for bulk material, it is significantly greater by up to two orders of magnitude in the porous structure of the electrode. The exact value depends on many parameters, in particular: porosity, state-of-charge (SoC), crystalline structure and particle …
In this paper, the materials generated from the battery''s positive with different discharge rate were used as the negative additive in the lead-acid battery.

The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.
Lead acid battery cell consists of spongy lead as the negative active material, lead dioxide as the positive active material, immersed in diluted sulfuric acid electrolyte, with lead as the current collector: During discharge, PbSO 4 is produced on both negative and positive electrodes.
