Battery degradation refers to the progressive reduction in a battery''s ability to store and supply energy as time passes. As the battery deteriorates over time, its capacity to store energy diminishes, resulting in less effectiveness in powering devices. Battery deterioration is an inherent phenomenon that impacts all rechargeable batteries
Several factors contribute to battery degradation. One primary cause is cycling, where the repeated charging and discharging of a battery causes chemical and physical changes within the battery cells. This leads to the gradual breakdown of electrode materials, diminishing the ability of the battery to hold a charge.
