Periodically changed current is called pulse current. It has been found that using the pulse current to charge/discharge lithium-ion batteries can improve the safety and cycle stability of the battery.
In this short review, the mechanisms of pulse current improving the performance of lithium-ion batteries are summarized from four aspects: activation, warming up, fast charging and inhibition of lithium dendrites.
Furthermore, a proposal to further enhance the effect of pulse current charging method is given, that is, the anion of the low coordination number should be selected to match with the lithium ion to promote the diffusion of Li and finally improve the electrochemical performance of the lithium metal battery.
Hence pulse charging can prolong the life of lithium-ion batteries [31, 32]. The battery can be preheated using pulse charging only when the capacity of the battery is more than 50% since the pulsed heating method involves pulse discharging, which consumes the capacity of battery .
The pulsed current charging technique is expected to improve the lifetime, charging speed, charging/discharging capacity, and the temperature rising of Li-ion batteries. However, the impact of the pulsed current parameters (i.e., frequency, duty cycle, and magnitude) on characteristics of Li-ion batteries has not been fully understood yet.
Additionally, the average input current of some of the previous pulse methods [10, 11] is even greater than the constant current and constant voltage charging method, which can't make a fair comparison and cannot reflect the fundamental advantages of the pulse charging mode.
