NOHMs raises $5M for commercializing non-flammable, ionic-liquid containing electrolytes for EV batteries
NOHMs Technologies Inc. (NOHMs), a Cornell University spin-out founded in 2010, raised $5 million in Series B venture capital financing to commercialize its non-flammable electric vehicle (EV) battery electrolyte technology. Phoenix Venture Partners II LP (PVP) led the round with Solvay Ventures, New York State Innovation Venture Capital Fund (NYSIVCF), and angel investors.
NOHMs Technologies has developed a family of ionic-liquid-containing electrolytes that are stable above 4.5 volts in lithium ion cells. The two electrolyte product lines currently under development for electric vehicle (EV) batteries are:
NanoLyte Electrolyte: SF Series. Non-flammable electrolyte to improve EV battery durability. This electrolyte is a drop-in replacement for commercial ionic liquids used in PHEV and EV cells.
NanoLyte Electrolyte: HVE Series. High voltage electrolyte for cell charge voltage above 4.35 V to improve EV battery energy density. This electrolyte is compatible with advanced electrodes that charge between 4.45 V and 4.95 V.
NanoLyte Electrolyte contains ionic liquids, which are non-flammable. By engineering the molecular structure, we can create electrolytes that are abuse tolerant without sacrificing the power or battery life.—Dr. Surya Moganty, CTO at NOHMs and inventor of the technology
In 2015, the United States Advanced Battery Consortium LLC (USABC), a collaborative organization of FCA US LLC, Ford Motor Company and General Motors, awarded a $1.64-million contract to NOHMs (Nano Organic Hybrid Materials) Technologies for the development of electrolytes for automotive lithium-ion battery applications. (Earlier post.) The competitively bid contract award is co-funded by the US Department of Energy (DOE) and includes a 50% cost-share by NOHMs.
The 18-month program is focusing on the development of functional, ionic liquid-based electrolyte and co-solvent combinations that exhibit high ionic conductivity and stability for application in 4.6-5.0-volt lithium-ion batteries.
In that project, NOHMs is collaborating with A123 (cell build and testing) and CoorsTek (ionic liquid synthesis and cost analysis).
