Phosphate Esters [Battery Additives] — compiles phosphate and phosphite esters with various alkyl, aryl, silyl, or propargyl groups that serve as electrolyte additives in battery formulations. Functional groups such as fluorine, alkene, or silyl in their structures affect electrochemical stability and the formation of passivation layers on electrodes.
Phosphate and phosphite esters in this category are used as functional additives in electrolytes for lithium-ion batteries as well as next-generation batteries to form a stable solid electrolyte interphase (SEI) and to improve the flame-retardant properties of the electrolyte. Battery materials researchers and engineers choose compounds with specific groups, for example trifluoroethyl or propargyl, to tune performance within a particular voltage or operating temperature range.

Pay attention to the substituent groups (alkyl, aryl, silyl, or fluoroalkyl) that suit the electrolyte system being developed, as well as purity and water content, since these affect electrochemical stability and additive performance in battery cells. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
