The American company Group14 Technologies, based in Washington, announced an important advance in the performance of silicon batteries with its SCC55 material, which now allows rechargeable batteries to exceed 1,500 charge cycles – surpassing the old 1,000-cycle standard of lithium-ion batteries.
In some cases, performance has reached more than 3,000 cycles, without compromising benefits such as fast charging and high energy density.
Innovative material is the differential of the battery
- SCC55 is a stable silicon and carbon compound that can totally or partially replace graphite in battery anodes, increasing energy density by up to 50% and offering up to five times the capacity of conventional graphite.
- The rigid carbon structure keeps the silicon in an ideal amorphous and nanometric shape, ensuring greater durability.
- The material is compatible with several battery chemicals, such as LFP, LMFP and high nickel systems, and is already being used in electric vehicles, artificial intelligence devices, eVTOLs (electric take-off and vertical landing vehicles) and storage in electrical networks.
Battery has already been used globally
Manufactured through the Scaffold Prime process, the SCC55 is produced at the company’s factory in Woodinville, Washington, and is being adopted by more than 20 global customers.
With this advance, silicon batteries not only overcome their old life limits, but also set a new standard for the next generation of high-performance rechargeable batteries.
