Problem
Current lithium-ion battery anodes, primarily made of graphite, limit energy density and charge rates, hindering the performance of electric vehicles, portable devices, and other high-energy applications. While silicon offers significantly higher lithium-ion storage capacity, its volumetric instability during charging and discharging leads to rapid capacity degradation and short battery lifecycles.
Solution
NorcSi has developed a patented silicon anode technology that enables the integration of 100% silicon anodes into existing lithium-ion battery production processes. This technology overcomes the limitations of conventional graphite anodes by leveraging a unique process to create stable silicon nanostructures within a thin layer of pure silicon. The resulting anode exhibits significantly increased energy density and charging rates while maintaining mechanical stability over numerous charging cycles. NorcSi's anodes are manufactured using a cost-effective and scalable roll-to-roll process, making them suitable for various cell types, including lithium-ion, lithium-sulfur, and solid-state batteries.
Target Audience
The primary target audience includes battery manufacturers and automotive companies seeking to improve the energy density and charging performance of lithium-ion batteries for electric vehicles, as well as manufacturers of portable electronic devices and drones.
