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

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.

Why do lithium batteries corrode at low temperature?

The resulted SEI typically is comprised of increased organic intermediate products, relating to uneven Li + transport and deposition. In addition, dendritic Li deposits and localized short-circuits of batteries are more frequently at low temperature. Additionally, the corrosion behavior of Li at low temperature should also not be overlooked.

Do Li salts improve battery performance in low-temperature conditions?

Li salts as the solutes of electrolytes provide cation and anion in the batteries, which obviously are responsible for the ion transport and SEI formation, exhibiting evident impacts on battery performance. Therefore, the selection and design of Li salts plays a crucial role in optimizing the performance of LMBs in low-temperature conditions.

What is a low-temperature LMB?

Low-temperature evaluation of real pouch cells and anode-free batteries. At present, the research on low-temperature LMBs is mainly conducted in coin-type cells, where flooded electrolyte and low-mass-loading cathode are frequently used with a high negative/positive (N/P) ratio.

Can external physical fields regulate the low-temperature operation of batteries?

In addition, external physical fields can also be potentially used to regulate the low-temperature operation of batteries. For example, the external magnetic field and pressure can be used to suppress the dendritic Li growth (Fig. 8 e) [, , , , ].
