OS3 is the latest generation in performance enhancing 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%.
· Greater capacity
· Longer life
· Extended temperature ranges
· Higher charge voltage
· Safety & stability
Liquid electrolytes in Li-ion batteries consist of a lithium salt, usually LiPF6, in an organic solvent blend of ethylene carbonate (EC) and one or more co-solvents such asdimethyl carbonate (DMC), diethyl carbonate (DEC), or ethylmethyl carbonate (EMC). Unfortunately, LiPF6 is unstable in these carbonate solvents above 60 degrees C, and at charge voltages above 4.3 volts. Operation of a Li-ion battery above these temperatures or voltages results in rapid degradation of electrode materials and battery performance. In addition, current Li-ion electrolyte solvents exhibit flashpoints around 35 degrees C, and are the major source of the energy released during an extreme Li-ion cell failure. Given these significant limitations, current electrolytes are impeding the development of advanced Li-ion batteries for all applications, including portable products, electric drive vehicles (EDVs), and utility scale use. A dramatic reduction in battery failure rate is also required for large scale Li-ion batteries to effectively serve applications in EDVs and grid storage.
Among industry leaders, there is nearly universal recognition of the need for improved electrolytes in energy storage devices such as Li-ion batteries. To respond to this opportunity, Silatronix is using the versatility of silicon chemistry to develop unique silicon-based materials for use as electrolytes.
