Abstract
Dendrite growth of lithium (Li) metal anode severely hinders its practical application, while the situation becomes more serious at low temperatures due to the sluggish kinetics of Li-ion diffusion. This perspective is intended to clearly understand the energy chemistry of low-temperature Li metal batteries (LMBs). The low-temperature chemistries between LMBs and traditional Li-ion batteries are firstly compared to figure out the features of the low-temperature LMBs. Li deposition behaviors at low temperatures are then discussed concerning the variation in Li-ion diffusion behaviors and solid electrolyte interphase (SEI) features. Subsequently, the strategies to enhance the diffusion kinetics of Li ions and suppress dendrite growth including designing electrolytes and electrode/electrolyte interfaces are analyzed. Finally, conclusions and outlooks are drawn to shed lights on the future design of high-performance low-temperature LMBs.
