This review summarizes the state-of-art progress in electrode materials, separators, electrolytes, and charging/discharging performance for LIBs at low temperatures.
Are lithium-ion batteries good at low temperature?
Modern technologies used in the sea, the poles, or aerospace require reliable batteries with outstanding performance at temperatures below zero degrees. However, commercially available lithium-ion batteries (LIBs) show significant performance degradation under low-temperature (LT) conditions.
How to improve the low-temperature properties of lithium ion batteries?
In general, from the perspective of cell design, the methods of improving the low-temperature properties of LIBs include battery structure optimization, electrode optimization, electrolyte material optimization, etc. These can increase the reaction kinetics and the upper limit of the working capacity of cells.
Do lithium-ion batteries deteriorate under low-temperature conditions?
However, commercially available lithium-ion batteries (LIBs) show significant performance degradation under low-temperature (LT) conditions. Broadening the application area of LIBs requires an improvement of their LT characteristics.
What are the interfacial processes in lithium-ion batteries at low temperatures?
Here, we first review the main interfacial processes in lithium-ion batteries at low temperatures, including Li + solvation or desolvation, Li + diffusion through the solid electrolyte interphase and electron transport.
How to overcome Lt limitations of lithium ion batteries?
Two main approaches have been proposed to overcome the LT limitations of LIBs: coupling the battery with a heating element to avoid exposure of its active components to the low temperature and modifying the inner battery components. Heating the battery externally causes a temperature gradient in the direction of its thickness.
Why do lithium ion batteries have a higher resistance at low temperatures?
The increased resistance at low temperatures is believed to be mainly associated with the changed migration behavior of Li + at each battery component, including electrolyte, electrodes, and electrode-electrolyte interphases [21, 26].
