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.

Are lithium-ion batteries able to operate under extreme temperature conditions?

Lithium-ion batteries are in increasing demand for operation under extreme temperature conditions due to the continuous expansion of their applications. A significant loss in energy and power densities at low temperatures is still one of the main obstacles limiting the operation of lithium-ion batteries at sub-zero temperatures.

Can Li metal batteries work at a low temperature?

Additionally, ether-based and liquefied gas electrolytes with weak solvation, high Li affinity and superior ionic conductivity are promising candidates for Li metal batteries working 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

Do lithium-ion batteries have electrode/electrolyte interface control?

Then, recent progress on the electrode surface/interface modifications in lithium-ion batteries for enhanced low-temperature performance is presented in detail. The lasting challenges and perspectives regarding electrode/electrolyte interface control in low-temperature lithium-ion batteries are finally discussed.

How does low temperature affect lithium ion transport?

At low temperature, the increased viscosity of electrolyte leads to the poor wetting of batteries and sluggish transportation of Li-ion (Li +) in bulk electrolyte. Moreover, the Li + insertion/extraction in/from the electrodes, and solvation/desolvation at the interface are greatly slowed.
