The aging process of lithium-ion is cell oxidation

The energy storage of a battery can be divided into three imaginary segments known as the availableenergy, theempty zonethat can 51J0499 replacementbe refilled, and the unusable part, or rock content that has become inactive. Figure 1 illustrates these three sections.

The manufacturer bases the runtime of a device on a battery that performs at 100 percent; most packs in the field operate at less capacity. As time goes on, the performance declines further and the battery gets smaller in terms of energy storage. Most users are unaware of capacity fade and continue to use the battery. A pack should be replaced when the capacity drops to 80 percent; however, the end-of-life threshold can vary according to application, user preference and company policy.

Besides age-related losses, sulfation and grid corrosion are the main killers of lead acid batteries. Sulfation is a thin layer that forms L08O6C02 replacementon the negative cell plate if the battery is allowed to dwell in a low state-of-charge. If sulfation is caught in time, an equalizing charge can reverse the condition.

Read about Sulfation. Grid corrosion can be reduced with careful charging and optimization of the float charge. With nickel-based batteries, the so-called rock content is often the result of crystalline formation, also known as “memory,” and a full discharge can sometimes restore the battery. The aging process of lithium-ion is cell oxidation, a process that occurs naturally as part of usage and aging and cannot be reversed.
