A higher cycle life indicates that the battery can be recharged and used more times without losing its efficiency, making it more viable for long-term applications.

The underlying mechanism behind this phenomenon involves the physical and chemical changes that occur within the battery during charging and discharging. Each cycle causes wear and tear on the battery’s active materials and electrolyte, leading to a gradual degradation of performance. As the battery goes through repeated cycles, the formation of solid electrolyte interphase (SEI) layers can increase resistance, and active materials may undergo structural changes, thereby impacting capacity retention over time. Therefore, batteries with a longer cycle life are engineered to minimize these detrimental changes, allowing them to sustain performance over a greater number of cycles.

Furthermore, external factors such as temperature, charge rates, and depth of discharge also play a significant role in determining cycle life. A study published in the Journal of Power Sources found that operating within optimal temperature ranges and avoiding deep discharges can substantially extend the cycle life of rechargeable batteries (Source: Journal of Power Sources, 2020).
