Li-ion cell designs are pushing the technical limitations of carbonate electrolyte to a breaking point. In order to meet increasing demand for energy density, wide operating temperature, and long cycle life, dramatic improvement in electrolyte stability is required. These improvements can be used to help enable higher silicon containing anodes and higher nickel containing cathodes. Li salt and electrolyte decomposition is a major performance issue in modern Li-ion batteries. Silatronix organosilicon electrolyte cosolvent materials enable high temperature and high voltage stability with substantial cycle life improvement by directly addressing electrolyte decomposition. This presentation will highlight how Silatronix is working with cell manufacturers to rebalance electrolyte formulations with commercially available organosilicon electrolyte to optimize cell level performance as well as market and technology impacts for future electrolyte materials.

Tobias Johnson is Applications Engineering Manager at Silatronix. He joined the company in 2013 to develop organosilicon (OS) electrolyte technology for Lithium Ion applications. His current focus is to support commercialization efforts and develop application guidance for the first Silatronix product, OS3. OS3 is a new and unique organosilicon Li-ion electrolyte co-solvent. Tobias and the Silatronix team work closely with a large number of tier 1 Li-ion cell manufacturers, material manufacturing partners, and electrolyte formulators supporting new product development of state of the art Li-ion cells containing Silatronix OS3 electrolyte material.

Silatronix is commercializing a new class of patented materials based on organosilicon (OS) compounds for use in energy storage devices, especially electrolytes for lithium-ion batteries (LiBs). OS compounds are environmentally friendly, non-flammable, high temperature materials suited for use as electrolytes, binders, and coatings in energy storage devices. In LiBs, OS materials can enhance thermal stability and safety, enable use of high energy density anodes and high voltage cathodes, and be cost effectively produced using existing manufacturing processes for silicone polymers.
