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 STOPS ELECTROLYTE BREAKDOWN

It is well understood that in Li-ion batteries, LiPF6 can break down into LiF and PF5. When that occurs, PF5 starts the autocatalytic process of HF production. HF production inside a Li-ion battery leads to the shortening of life, reduction in performance, and decomposition of other materials inside of the cell. Silatronix® OS3® material helps to stop LiPF6 breakdown, preventing HF production inside the cell. To see example test data, click here


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.
