Customer ServiceFrom a baseline, we introduce the progress in recently emerging electrolyte development for low-temperature Li-ion batteries, including localized high-concentration electrolytes, liquefied gas electrolytes, and weakly solvating electrolytes.
To investigate potential factors dictating the performance of low-temperature electrolytes, we computed the viscosity (η) of the electrolyte and analyzed its response to changes in concentration and temperature, shown in Fig. S13 (ESI †). As the concentration increases, the viscosity of the electrolyte increases.
Especially at low temperature, the increased viscosity of the electrolyte, reduced solubility of lithium salts, crystallization or solidification of the electrolyte, increased resistance to charge transfer due to interfacial by-products, and short-circuiting due to the growth of anode lithium dendrites all affect the performance and safety of LIBs.
Building on the concept of high-entropy electrolytes, they formulated a solvent mixture with molecular disorder, resulting in a lower freezing point of −130 °C and a substantially extended service temperature range for Li-ion batteries. 5. Conclusion and perspective
The electrolyte in this type of battery consists of a combination of dry porous solid polymer and gel-like solvents, to improve thermal stability, conductivity, and ion transfer in the conductive membrane during operation.
Plichta et al. found that LIBs with the electrolyte EC/DMC/EMC containing LiPF 6 retained 52% of their capacity at –40°C. As a result, the system exhibited high conductivity and electrochemical stability. This electrolyte has been proven to perform well in LIBs at temperatures as low as –40°C.
