Wildcat Discovery Technologies Introduces SuperFilm Electrolyte Technology
Jun 8 15
Wildcat Discovery Technologies announced the discovery of its new SuperFilm electrolyte technology enabling superior electrode SEI film-forming properties. The properties and quality of the solid electrolyte interphase (SEI) layer are critical to achieving high cycle life, high rate performance, and wide operating temperature ranges in a battery. However, SEI layers on graphite anodes are generally non-uniform and have incomplete surface coverage. To achieve stable performance, additives must accomplish two things: deposit uniformly on the electrode surface and form a mechanically and electrochemically stable coating. Finding single additives that achieve both things well has proven difficult, and combining two functional additives often creates antagonistic effects. Wildcat's SuperFilm technology decouples film formation from functionality for electrolyte additives and consequently opens the door for using and combining new compounds in electrolyte formulations. Wildcat has validated the performance benefits of SuperFilm with a variety of cell chemistries and voltages, including both standard and Ni-rich NMC (4.45V), LCO (4.35V), and LMNO (4.9V). Both room temperature and high temperature cycle life results were improved in all cases.
