ENABLING HIGH PERFORMANCE THROUGH SILICON CHEMISTRY

OS3

OS3 is the latest generation in performance enhancing organosilicon electrolyte materials available from Silatronix. OS3 enables extreme performance of Li-ion batteries when added to LiPF6 based battery cells in concentrations of just 2-5%. OS3 provides dramatic performance enhancements while also delivering substantial safety and stability improvements. Silatronix is currently delivering production volumes of OS3. The material is ready for use in commercial Li-ion battery applications globally. OS3 material has been, or is currently in the process of, complete chemical registration in all major Li-ion battery manufacturing locations.

OS3 ELECTROLYTE STABILITY

HIGHER PERFORMANCE WITH IMPROVED SAFETY

Silatronix OS3 is thermally and electrochemically stable. The stability benefit translates to improved battery safety and stability when modest amounts of OS3 are added to Li-ion battery electrolytes as a co-solvent. By providing improved electrolyte stability, OS3 is enabling safer application of higher voltage and higher energy density Li-ion battery systems.

APPLIED LITHIUM SOLVENT

OS3 is a solvent, not a traditional additive. This is an important distinction to make given that OS3 is applied in “additive-like” quantities. The difference is that OS3 is a complementary part of the Li-ion electrolyte and additive system. While additives are typically consumed during the first few cycles of a battery, Silatronix OS3 works as a component of the system. The material stays as part of the electrolyte formulation throughout the life of the battery. OS3 compliments the LiPF6 system by modifying the decomposition behavior through its solvation mechanisms. Through our research in applying OS3, Silatronix has developed a high level of internal Li-ion battery electrolyte formulation expertise to support integration of OS3 into Li-ion cell designs.
