In this review, we summary the usage of pulse current in lithium-ion batteries from four aspects: new battery activation, rapid charging, warming up batteries at low temperature, and inhibition of lithium dendrite growth. 1. Introduction
However, this operation increases the charging time. Miller et al. introduced a simulation model showing that the short time pulse current could balance the reaction kinetics on the anode surface at the large current density, thus reduce the deposition of lithium cations in secondary lithium metal batteries.
At low temperature, the decrease of electrolyte conductivity and lithium ion diffusion rate significantly increase the internal resistance of LIBs, thereby degrading the battery performance.
The constructed SEI film has strong stability and good conductivity and can effectively improve the cycle stability of the battery. Slow charging rate is an important factor hindering the practical application of LIBs.
The low temperature environment will reduce the LIB performances. However, the pulse current can quickly generate heat inside the battery, thereby reducing the damage to the battery caused by the low temperature. The safety problem caused by lithium dendrites is a key factor limiting the application of lithium metal electrode.
