Battery know-how firm Sionic Vitalityalong with Group14 Applied scienceshas introduced the outcomes of testing that demonstrates a brand new degree of high-temperature stability for 100% silicon-carbon anodes in lithium-ion cells.
By combining Group14’s SCC55 silicon-carbon anode materials with Sionic’s proprietary Speedy Integration Silicon Platform containing 100% silicon-carbon (Si-C) anode and enhanced electrolyte, the businesses “have set a brand new benchmark for silicon battery know-how, increasing its path to a broader set of purposes in transportation, shopper electronics and aviation markets.”
The businesses examined Sionic’s Speedy Integration Silicon Platform with SCC55 in 4 Ah, 10 Ah and 20 Ah pouch cells underneath electrolyte-lean situations with NMC 83 cathodes. The cells delivered steady 1C/-1C biking at 45° C, and retained >70% of room-temperature cycle life. Storage testing at 45° C and 60° C displayed substantial suppressed fuel technology and decrease impedance development, supporting the potential of prolonged calendar life over baseline chemistries.
Sionic says its graphite-free Speedy Integration Silicon Platform delivers particular vitality of as much as 400 Wh/kg, cycle lifetime of over 1,200 cycles, and robust efficiency, in cell codecs already utilized by companions.
“Our Speedy Integration Silicon Platform delivers as much as a 50% bounce in efficiency whereas dropping proper into industry-standard tools with no complexity: no pre-lithiation, no exterior compression, no intensive cell design efforts,” mentioned Ed Williams, President and CEO of Sionic Vitality.
“This benchmark is a robust validation that silicon batteries are market-ready,” mentioned Rick Luebbe, CEO and co-founder of Group14 Applied sciences. “Prospects need true drop-in silicon-carbon anodes that ship as much as 50% increased vitality density, dramatically sooner charging, and sturdy lifetime throughout excessive temperatures. These newest outcomes with 100% SCC55 present that we are able to meet these expectations at scale, in the present day.”
A technical white paper with full check information is obtainable to certified OEMs, cell producers and traders.
