Can lithium-ion batteries be used at low temperatures?

Challenges and limitations of lithium-ion batteries at low temperatures are introduced. Feasible solutions for low-temperature kinetics have been introduced. Battery management of low-temperature lithium-ion batteries is discussed.

Are low-temperature lithium batteries dangerous?

In general, there are four threats in developing low-temperature lithium batteries when using traditional carbonate-based electrolytes: 1) low ionic conductivity of bulk electrolyte, 2) increased resistance of solid electrolyte interphase (SEI), 3) sluggish kinetics of charge transfer, 4) slow Li diffusion throughout bulk electrodes.

What is a low-temperature lithium battery?

Low-temperature lithium batteries have received tremendous attention from both academia and industry recently. Electrolyte, an indispensably fundamental component, plays a critical role in achieving high ionic conductivity and fast kinetics of charge transfer of lithium batteries at low temperatures (−70 to 0 °C).

Are unconventional carbonate electrolytes useful in low-temperature lithium batteries?

Although the emerging unconventional electrolytes possessing some distinct functions alleviated unique problems presented in low-temperature lithium batteries, there are still grand challenges and plenty of rooms for the rational investigation in low-temperature unconventional carbonate electrolytes.

How to extend the service-temperature range of lithium batteries?

Formulating electrolytes with solvents of low freezing points and high dielectric constants is a direct approach to extend the service-temperature range of lithium batteries. However, the SEI formed by the decomposition products of common electrolytes cannot satisfy the electrochemical properties at ultralow temperature.

Can Li stabilizing strategies be used in low-temperature batteries?

The Li stabilizing strategies including artificial SEI, alloying, and current collector/host modification are promising for application in the low-temperature batteries. However, expeditions on such aspects are presently limited, with numerous efforts being devoted to electrolyte designs. 3.3.1. Interfacial regulation and alloying
