Sustainable Battery Materials from Biomass.

Area of Science:

• Materials Science
• Electrochemistry
• Sustainable Energy

Background:

• Current energy storage heavily relies on heavy metals, posing environmental concerns.
• Organic batteries, particularly those derived from biomass, present a promising sustainable alternative.
• Research in biomass-derived electrodes has grown significantly since 2008.

Purpose of the Study:

• To review recent advancements in biomass-derived organic batteries.
• To highlight the potential for fully biowaste-derived energy storage solutions.
• To explore the use of biomass in various battery components.

Main Methods:

• Review of existing literature on biomass-derived battery materials.
• Analysis of carbonized and non-carbonized biomass applications in electrodes.
• Investigation of biomolecules (quinones, flavins, carboxylates) as redox-active components.
• Exploration of biomass-based binders, electrolytes, and separators.

Main Results:

• Biomass can be carbonized for use in anodes (lithium-ion, sodium-ion) and cathodes (metal-sulfur, metal-oxygen).
• Biomolecules offer redox-active sites for electrode development with minimal modification.
• Biomass-based binders can replace toxic halogenated binders.
• Electrolytes and separators can also be synthesized from biomass.

Conclusions:

• Biomass-derived materials offer a pathway to truly sustainable energy storage.
• Fully biowaste-derived batteries are a feasible and rapidly emerging technology.
• Continued research is crucial for optimizing performance and scalability.
