Summary: The sluggish evolution of lithium ions' solvation sheath can lead to dendrite formation and capacity loss in lithium batteries, especially at low temperatures. However, by using an ion-dipole strategy to regulate the fluorination degree of solvating agents, it is possible to accelerate the evolution of Li+ solvation sheath and improve battery performance. The DFEC-based electrolyte demonstrates significantly faster ion desolvation rate at low temperatures, allowing for better capacity retention in LiNi0.8Co0.1Mn0.1O2||lithium cells after cycling. This work provides a new technique towards rational design of electrolyte engineering for low-temperature lithium batteries.

Summary: The energy density of LIBs has been increased threefold since their introduction, but the capacity of transition metal oxide cathodes is approaching its limit due to stability limitations of electrolytes. To further enhance energy density, new high-capacity and high-voltage cathode materials need to be explored, and graphite anodes may need to be replaced. One of the main challenges for future development is the development of new electrolyte compositions that can accommodate high-voltage cathodes and anodes while ensuring the stability of the batteries.

However, the poor morphological stability and Coulombic efficiency of the lithium metal anode in liquid electrolytes present challenges for reversible cycling. Experimental and theoretical insights are being used to explore pathways for stable cycling of two-dimensional lithium metal and improvements in understanding lithium metal nucleation and deposition on the nanoscale. Recent advances in electrolytes and SEI design show potential for stable cycling and mitigation of morphological instabilities.
