New energy batteries overcome low temperatures

How to improve battery performance in low-temperature environments?

In general, enlarging the baseline energy density and minimizing capacity loss during the charge and discharge process are crucial for enhancing battery performance in low-temperature environments [, , , ].

Are lithium-ion batteries suitable for low-temperature use?

In this article, a brief overview of the challenges in developing lithium-ion batteries for low-temperature use is provided, and then an array of nascent battery chemistries are introduced that may be intrinsically better suited for low-temperature conditions moving forward.

How does low temperature affect battery performance?

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 .

What are the advantages of a low-temperature battery?

The prerequisite to support low-temperature operation of batteries is maintaining high ionic conductivity. In contrast to the freezing of OLEs at subzero temperatures, SEs preserve solid state over a wide temperature range without the complete loss of ion-conducting function, which ought to be one of potential advantages.

How to design a low-temperature rechargeable battery?

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.

Can self-heating technology be used in low-temperature batteries?

Presently, the self-heating technology is rarely reported on low-temperature LMBs, which should be extended and studied in the future work. In addition, external physical fields can also be potentially used to regulate the low-temperature operation of batteries.
