Seaweed-based battery powers confidence in sustainable energy storage

https://bristol.ac.uk/news/2022/october/seaweed-based-battery-.html

"seaweed-derived nanomaterials stop crystals from sodium electrodes penetrating separator, improve performance... separate functioning parts... allow free transport of charge... seaweed-based materials can make the separator very strong and prevent it being punctured by metal structures made from sodium. It also allows for greater storage capacity and efficiency, increasing the lifetime of the batteries - something which is key to powering devices such as mobile phones for much longer"
