Electrolytes
An electrolyte used in a lithium ion rechargeable battery dissociates in an organic solvent to impart lithium ion conductivity to the electrolytic solution. Since the electrolyte is a substance responsible for charge transport between the positive electrode and the negative electrode, it is an important material related to input/output characteristics and cycle life of the battery.
Our product is valuable for evaluation of potential of new batteries such as fluorinated sulfonimide (FSI) anion type electrolyte with high ionic conductivity and thermal decomposition temperature. FUJIFILM Wako Pure Chemical can support developing enhanced performance and safer battery operation.
