Exploring Nanocellulose-Based Materials for Energy Conversion and Storage Devices

Abstract

The planet must deal with the two main concerns of the twenty-first century: energy storage and protecting the environment. Energy storage systems urgently require green and sustainable electrode materials due to the rise in worldwide demand for energy and severe environmental damage. The biopolymer-based device reduces e-waste and environmental issues caused by conventional electronic devices. Nanocellulose is a solid choice for green electronics, due to its unique properties, like being eco-friendly, cost effective, biodegradable, having great mechanical strength, and remarkable optical clarity. With its exceptional qualities, sustainability and distinctive structures, nanocellulose has become a hopeful nanomaterial with enormous potential for creating useful energy storage systems. This review aims to offer novel viewpoints on flexible composites made of nanocellulose or nanocellulose-based materials for enhanced energy technologies. Initially, a brief introduction to the special structural features and attributes of nanocellulose is made. To improve these composites’ performances, the structure-property-application interactions must be addressed. The most recent uses of nanocellulose-based composites are then thoroughly reviewed. These include flexible solar cells, supercapacitors (SC), lithium-ion batteries and developing energy device innovations. Finally, nanocellulose-based composites for the next generation of energy devices are offered, along with their current difficulties and potential future developments.
