Boulder Ionics Corporation

Boulder Ionics Corporation was a Colorado-based company specializing in energy storage materials.

It developed and manufactured high-performance electrolytes for advanced electrochemical devices, including ultracapacitors and lithium-ion batteries. The company focused on ionic liquids and ionic-liquid-based electrolytes, marketed under the Iolyte brand. These products are known for being non-toxic, non-flammable, and stable across a wide range of temperatures. Boulder Ionics utilized a proprietary high-throughput synthesis platform to create ultra-high-purity ionic liquids and electrolytes designed for demanding energy-storage applications. Its offerings were suitable for various uses, including batteries, capacitors, consumer electronics, hybrid vehicles, electric vehicles, and grid-scale energy storage. Founded around 2010–2011 in Arvada, Colorado, Boulder Ionics was acquired by CoorsTek in October 2014 and became part of CoorsTek Specialty Chemicals.
