Silicon battery hits 3,000 cycles in performance breakthrough

Group14 Technologies, a Washington-based company, has announced a significant breakthrough in silicon battery performance with its SCC55 material, enabling silicon batteries to consistently achieve over 1,500 charge cycles and, in some cases, exceed 3,000 cycles. This milestone surpasses the longstanding industry benchmark of 1,000 cycles for high-performance lithium-ion batteries, marking a new era of durability combined with higher energy density and faster charging. The SCC55 technology is a stable silicon-carbon composite that holds up to five times the capacity of graphite and provides up to 50% more energy density for lithium-ion battery anodes. The novel SCC55 material is compatible with various battery chemistries, including lithium iron phosphate (LFP), lithium manganese iron phosphate (LMFP), and high-nickel formulations, and is already powering millions of products worldwide. Its advanced hard carbon-based scaffold keeps silicon in an amorphous, nano-sized form, enhancing battery longevity and performance. Manufactured via a scalable two-step process
