Currently, two solutions are available to decrease the capacity degradation caused by charging batteries at low temperatures: (1) reducing the charging current based on traditional charging schemes ; (2) preheating the battery with external devices before charging .
This paper has designed a temperature-aware charging strategy with adaptive current sequences to improve the charging performance of lithium-ion batteries in cold environments. An integrated battery model with time-varying parameters is established to reveal the relationship among battery electrical, thermal, and aging features.
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.
Briefly, the key for the electrolyte design of low-temperature rechargeable batteries is to balance the interactions of various species in the solution, the ultimate preference is a mixed solvent with low viscosity, low freezing point, high salt solubility, and low desolvation barrier.
Obviously, formulating electrolytes is an effective approach to tame the low-temperature challenges of Li metal batteries, while more efforts should be devoted to establishing the design criterion for such electrolytes. 3.2. Cathode modification
At low temperature, the high desolvation energy and low ionic conductivity of the bulk electrolyte limit the low-temperature performance of the LMBs . Such processes play important roles in deciding the low-temperature performances of batteries .
