Battery plates are the negative and positive electrodes. They contain the active material that stores energy in chemical form. In other words, they are where the electrochemical reaction responsible for charging and discharging occurs. Two plates of opposite polarity form a cell. In turn, several cells combine to make up the entire device.

The active material in the positive plates is lead dioxide and that in the negative is metallic sponge lead. Continued deep cycling of a ''stratified'' battery will result in softening of the bottoms of the positive plates and sulfation of the bottoms of the negative plates. Equalization charging is a way to avoid acid electrolyte
In the AGM battery design, the glass-mat separators are pressed tightly against the plates, and clearly, the resulting high stack-pressure helps to slow down the softening of the active-material. This means that large 4BS crystals with their accompanying formation problems can be avoided without detriment to cycling performance.

Car batteries can have problems like sulfation, water loss, and plate softening. Sulfation is when hard crystals form on the plates. This can make the battery lose power and need to be replaced. Charging and taking care of the battery are key to avoiding these issues. This helps the battery last longer. Battery Life Expectancy
To increase the capacity of lead-acid batteries, it is necessary to increase the porosity, increase the content of PbO2 and the proportion of sulfuric acid, but these measures will accelerate the softening of the positive plate, resulting in accelerated decline of the life of the lead-acid battery, and the active material will expand and shrink during the charging and

In electric vehicle service, high pulses of discharge current are required which place an extreme load on the battery. Accordingly, the phenomenon of softening of the positive mass has often limited the lifetime of the batteries 5, 14. At present, it appears that softening is a more severe problem than the development of barrier layers.

A softened plate increases the internal resistance of the battery, which can lead to excessive heat generation during charging and discharging. This heat can further accelerate the degradation
However, if we made a tear-down analysis of that battery, we would observe positive plates that appear to be in good shape, but the active material looks to be softening and muddy. In a battery suffering from acid stratification, the muddy appearance may be concentrated on the bottom of the plate.
A battery with highly sulphated negative plates will eventually only accept a surface charge, resulting in a false positive high state of charge readings. In this condition, a battery may appear fully charged but have a very low capacity, as expressed in Amp Hour (AH) or Reserve Capacity (RC).
This sulfation of the negative plate will cause battery performance to decline incrementally and result in premature battery failure. A battery with highly sulphated negative plates will eventually only accept a surface charge, resulting in a false positive high state of charge readings.
Muddy-positive plates are usually accompanied by negative plates that show signs of Sulfation. Since grid wires are the current collectors upon which electrical current is delivered to the starter (Cold Cranking Amps or CCA), corrosion decreases the electrical performance of the battery.
In a corroded battery, much of the current gets lost to resistance (in the form of heat) as the grid wires become exposed and/or disconnected from the active materials.
