II. Composition of The Electrolyte:

The electrolyte is composed of three parts: electrolyte, solvent, and additives, each serving the following roles:

Electrolyte: Provides lithium ions in the electrolyte, typically using lithium salts such as LiPF6, LiBF4, LiClO4, etc.

Solvent: Used to dissolve the electrolyte and additives, forming an ionic conductor, commonly using organic solvents such as carbonates, carboxylates, and ethers.

Additives: Used to improve the performance of the electrolyte, such as enhancing conductivity, stability, and corrosion resistance. Commonly used additives include conductive agents, film-forming agents, and corrosion inhibitors.

The performance of the electrolyte significantly impacts the performance and lifespan of lithium batteries. 

Therefore, when designing and preparing the electrolyte, it is essential to consider factors such as electrochemical performance, stability, safety, and cost. Additionally, the preparation and use of the electrolyte must strictly adhere to relevant safety regulations and operational procedures to ensure the safety and reliability of the battery.
