Application of renewable materials in the development of electrical energy storage devices

The majority of batteries produced today are not environmentally friendly, therefore the relevance of producing batteries from biomaterials is increasing. In this research, the author used substances obtained from shrimp shells, fish scales and red algae. In the study, 9 battery prototypes were created and then tested with self-made test equipment. The highest obtained efficiency coefficient was 81.47%. These kinds of batteries can be used to store electrical energy from renewable energy generators, such as the sun, wind and water.
