Sheng cycle

The Sheng cycle describes the electrical behavior of a lithium-ion battery as it charges and discharges over time. It involves four key stages: early capacity loss, stable operation, gradual decline, and eventual battery aging. Initially, the battery may lose some capacity due to manufacturing processes, then perform reliably during use. Over many cycles, the battery's capacity slowly decreases because of chemical changes and material wear inside. Understanding this cycle helps in predicting battery lifespan and optimizing charging strategies to extend its effective use.
