Electrolyte Design for Lithium Metal Anode-Based Batteries Toward Extreme Temperature Application

Area of Science:

• Electrochemistry
• Materials Science
• Energy Storage

Background:

• Lithium anode batteries (LBs) offer high theoretical capacity, crucial for electric vehicles and grid storage.
• Current LBs face performance limitations at extreme temperatures (<0°C and >60°C).

Purpose of the Study:

• To review challenges in developing LBs for extreme temperature operation.
• To introduce electrolyte design strategies for overcoming temperature-related performance issues.
• To evaluate specific lithium battery chemistries for extreme temperature applications.

Main Methods:

• Overview of challenges in low and high-temperature LB operation.
• Discussion of electrolyte design strategies: Li salt modification, solvation structure optimization, additives, and solid-state electrolytes.
• Evaluation of lithium metal batteries (LMBs), lithium sulfur (Li-S) batteries, and lithium oxygen (Li-O2) batteries.

Main Results:

• Extreme temperatures impede LB performance due to charge transfer resistance (low T) and side reactions (high T).
• Electrolyte modifications and advanced chemistries show promise for mitigating these issues.
• LMBs, Li-S, and Li-O2 batteries are presented as viable options for extreme temperature applications.

Conclusions:

• Electrolyte design is key to enabling practical LBs for extreme temperature environments.
• Further research into advanced electrolyte strategies is crucial for realizing the full potential of LBs.
• Optimized LBs are essential for performance-critical applications like EVs and grid storage.
