“…Xu et al 94 first studied the adhesion effect of lithium dendrites between the interface layer and lithium metal and they found that enhanced adhesion energy can help inhibit the growth of Li dendrite. Chen et al 95 investigated the thermal effect on the Li dendrites growth. Hong et al 96 further revealed that the temperature-dependent performance of batteries is related to the reaction barrier and ionic diffusion barrier.…”

Rechargeable batteries have a profound impact on our daily life so that it is urgent to capture the physical and chemical fundamentals affecting the operation and lifetime. The phase-field method is a powerful computational approach to describe and predict the evolution of mesoscale microstructures, which can help to understand the dynamic behavior of the material systems. In this review, we briefly introduce the theoretical framework of the phase-field model and its application in electrochemical systems, summarize the existing phase-field simulations in rechargeable batteries, and provide improvement, development, and problems to be considered of the future phase-field simulation in rechargeable batteries.

“…[16] High-temperature operation would directly facilitate Li + transfer, which can increase the concentrations of Li + in the region of dendrite tip. [17] Moreover, the rapid surface diffusion of Li + at high temperature is beneficial for packed Li deposition. Supporting evidence from electrochemical impedance spectroscopy (EIS) analysis clearly states lower interfacial resistance and charge transfer resistance before and after cycling at 60 8 8C( Figure S10).…”

Safety concerns pose as ignificant challenge for the large-scale employment of lithium-sulfur batteries.E xtremely flammable conventional electrolytes and dendritic lithium deposition cause severe safety issues.N ow,a ni ntrinsic flameretardant (IFR) electrolyte is presented consisting of 1.1m lithium bis(fluorosulfonyl)imide in as olvent mixture of flame-retardant triethyl phosphate and high flashpoint solvent 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl (1:3, v/v) for safe lithium-sulfur (LiÀS) batteries.T his electrolyte exhibits favorable flame-retardant properties and high reversibility of the lithium metal anode (Coulombic efficiency > 99 %). This IFR electrolyte enables stable lithium plating/stripping behavior with micro-sized and dense-packing lithium deposition at high temperatures.W hen coupled with as ulfurized pyrolyzed poly(acrylonitrile) cathode,L i ÀSb atteries deliver ah igh composite capacity (840.1 mAh g À1 )and high sulfur utilization of 95.6 %.

“…The previous result is in accord with previous experiments 53,54 and previous computational works. 55 In the case of ht Trel -CI, 742 Li-ions reach the anode in 88 ps while in the case of mt Trel -CI, 303 Li-ions reach the anode in 88 ps. In the case of lt Trel -CI in the same time period, 217 Li atoms reach the anode.…”
