[Analysis Case] Analysis of Solvents and Additives in Lithium-Ion Secondary Battery Electrolytes

Extraction of electrolyte from the product and component evaluation.

The characteristics and reliability of lithium-ion secondary batteries are greatly influenced by materials, among which the impact of the electrolyte is said to be significant. Commercial products in various shapes, such as cylindrical and laminated types, can have their electrolytes extracted using appropriate methods, allowing for the identification of organic solvents and additives. The following case involves extracts from prismatic batteries, confirming the use of ethylene carbonate (EC), ethyl methyl carbonate (EMC), and diethyl carbonate (DEC) as organic solvents, and fluoroethylene carbonate (FEC) as an additive.
