Recycling chicken eggshell membranes for high-capacity sodium battery anodes

As a waste recycling process, pyrolytic eggshell membrane carbonization can produce carbonized eggshell membrane (CEM) materials for sodium battery anodes. The CEM contains a high interconnectivity porous structure of carbon fiber networks with a controllable surface area and nitrogen content. The electrochemical properties of CEM combined with this process have potential applications in providing a new type of sustainable resource for clean energy storage.
