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

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.

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.

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.

How solvation structure affect low-temperature battery cycling?

Adjusting the solvation structure is also an effective strategy for low-temperature LMBs. In addition to the type and proportion of solvents, the intricate interactions among solvents, Li salts, and additives are also of great significance to the low-temperature battery cycling.

Does LMO/Li battery have a high diffusion coefficient?

Li et al. reported that LMO/Li battery still has a high Li + diffusion coefficient of 10 –12 cm 2 s -1 at −20 °C compared to that of room temperature (10 –10 cm 2 s -1) . However, LMO delivers higher R ct than LFP and LCO at various low temperature.
