Sionic Energy specializes in developing next-generation lithium-ion battery technology, focusing on silicon anode and advanced electrolyte solutions. The company creates high-performance batteries that deliver 50% higher energy density while reducing production costs by up to 30% compared to traditional lithium-ion batteries. Originally established in 2011 as NOHMs Technologies by scientists from Cornell University, the company has transformed into a leading innovator in silicon-based battery solutions. Their technology is designed for seamless integration into existing manufacturing processes, making it particularly attractive for automotive, consumer electronics, and aviation applications.
Battery Technology
Sionic Energy’s primary innovation combines two distinct technological advances. First, their pure silicon anode technology uses low-cost micron silicon, developed in collaboration with Professor Sehee Lee’s team at the University of Colorado Boulder. This advancement significantly increases energy storage capacity compared to conventional graphite anodes.
The second component involves proprietary electrolyte additives that enhance both anode and cathode performance. These additives are specifically engineered to extend battery life while improving safety by reducing thermal runaway risks. Through partnership with Group14 Technologies, Sionic Energy utilizes SCC55TM silicon-carbon composite material to create 100% silicon batteries that achieve specific energy performance of 330 Wh/kg and energy densities of 842 Wh/L, with cycle life reaching up to 1,200 full cycles.
The company’s manufacturing approach allows for direct integration into existing production facilities, supporting various cell formats including cylindrical, pouch, and prismatic designs. This flexibility enables rapid market adoption without requiring significant changes to current manufacturing infrastructure.
Recent Projects
In their most recent development, Sionic Energy has focused on scaling up their battery production capabilities. The company is preparing for commercial deployment in multiple sectors, starting with aviation and consumer electronics in 2025. They are currently testing larger 20 Ah cells aimed at achieving energy density of 370 Wh/kg and 1,000 Wh/L. Their collaboration with Group14 Technologies continues to advance, with plans for a new factory in Moses Lake, Washington, opening in early 2025 to produce essential silicon anode materials.
Investors
Sionic Energy has attracted investment from substantial industry players and venture capital firms. Notable investors include Phoenix Venture Partners, Solvay, Aravaipa Ventures, and Empire State Development. The company has also secured backing from In-Q-Tel, Venture Partners at CU Boulder, and The Center for Technology Licensing at Cornell University. These partnerships provide both financial support and strategic expertise to advance Sionic Energy’s battery technology development.
