Next-Gen Silicon Active Anodes: Sustainability & Recyclability

#Silicon-based anodes, with their high-capacity features, are essential for energy storage applications, with their potential to enhance both storage capacity and energy density. Nevertheless, their extraction and processing come with high carbon emissions and energy consumption, posing environmental challenges.

To address these issues, developments include the use of #greenhydrogen to replace carbon in the reduction process, plus the use of bio-carbon and carbon capture for carbon-neutral or carbon-negative production. Also, experimental metallothermic and electrochemical methods are being developed to produce high-purity silicon with minimal emissions.

The Norwegian University of Science and Technology (NTNU) is also developing a green silicon production method, called SisAl, which uses aluminium instead of carbon as a reducing agent.
