Charging a lithium-ion battery with high currents can deteriorate its cycle life by provoking lithium plating. This can be observed clearly for cell models A and C, where the comparison of CCCV protocols with different charging currents has revealed a lower cycle life for a higher charging current.
Lithium-ion batteries operate differently. They charge under a constant current and switch to a continuous voltage later in the charging cycle. The charging process reduces the current as the battery reaches its full capacity to prevent overcharging.
As the charging rate increases, the faster the active material reacts, the faster the battery voltage increases, and the energy loss generated increases. Therefore, the actual charging capacity of the Li-ion battery with high current charging is lower than the charging capacity when charging with low current.
At low temperature, lithium-ions diffuse more slowly in the electrode and electrolyte, and the intercalation dynamics are slow. In this case, the continuous charging of the battery will lead to a rapid decline in capacity, seriously limiting the application of LIBs .
Our investigations on pulse charging show that lithium-ion cells withstand charging pulses of high current or high voltage without any deterioration in cycle life, when the duration of the pulses remains short and the mean current and voltage values are considerably lower.
Our experimental cycle life study on charging protocols for lithium-ion batteries has shown that a sophisticated study design is essential for separating the effects of different parameters on the performance of charging protocols.
