In fact, the internal charging mechanism of a lithium-ion battery is closely tied to the chemical reactions of the battery. Consequently, the chemical reaction mechanisms, such as internal potential, the polarization of the battery, and the alteration of lithium-ion concentration, have a significant role in the charging process.
Traditionally, the current rate (C-rate) influences the performance-degradation behavior of LIBs. Thus, the charging method impacts the performance and lifetime parameters of the LIB . On the other hand, the battery discharging is determined by the consumer's energy consumption behavior.
Since the charging method can impact the performance and cycle life of lithium-ion batteries, the development of high-quality charging strategies is essential. Efficient charging strategies need to possess advantages such as high charging efficiency, low battery temperature rise, short charging times, and an extended battery lifespan.
