Lithium-ion batteries are a type of battery that use lithium metal or lithium alloy as positive/negative electrode materials and a non-aqueous electrolyte solution. Lithium-ion batteries are closely related to people’s daily lives, and there are many companies worldwide that produce and manufacture them.

In order to meet production standards, the concentration of solvents such as NMP, DMAC, and DMSO in the production process of lithium-ion batteries is usually monitored in real-time.
