Cellulose from waste materials for electrochemical energy storage applications: A review

Abstract

The world is weakening because most energy sources currently in use are environmentally hazardous. On the other hand, clean and alternative energy sources have the potential to save our planet. Renewable energy sources, including wind, solar, and biomass, are being marketed as viable alternatives to non-renewable energy sources. These renewable energy sources are only available on a seasonal basis. As a result, creating novel, low-cost, and long-lasting electrochemical energy storage technologies is essential for making the best use of these renewable energy sources. Thus, electrochemical storage devices such as batteries and supercapacitors, which are energy conversion and storage technologies for practical application to achieve a circular economy, are the most effective. Cellulose, being the most prevalent natural polymer on the earth, has proven to possess a lot of potential in this application. In this review, we focused on cellulose, electrochemical energy storage devices, and how cellulose derived from biomass or waste materials can be used for electrochemical energy storage.
