Sionic Energy’s core technology combines a pure silicon anode using low-cost micron silicon developed with the University of Colorado Boulder and proprietary electrolyte additives that extend battery life and improve safety by reducing thermal runaway risks. In partnership with Group14 Technologies, it employs SCC55™ silicon-carbon composite to create 100% silicon batteries achieving 330 Wh/kg energy performance, 842 Wh/L energy density, and up to 1,200 full cycles. Its manufacturing approach enables direct integration into existing cylindrical, pouch, and prismatic cell production lines.
Products include 100% silicon batteries delivering 330 Wh/kg and 842 Wh/L with 1,200-cycle life; upcoming 20 Ah cells targeting 370 Wh/kg and 1,000 Wh/L energy density.
Preparing commercial deployment in 2025 for aviation and consumer electronics; scaling up production and testing 20 Ah cells; collaborating with Group14 Technologies; opening a silicon anode materials factory in Moses Lake, Washington in 2025.
Sionic Energy is backed by Phoenix Venture Partners, Solvay, Aravaipa Ventures, Empire State Development, In-Q-Tel, Venture Partners at CU Boulder, and the Center for Technology Licensing at Cornell University.
