Consortium Led by University of Würzburg Targets Sodium Batteries’ Efficiency and Sustainability
In a concerted effort led by the University of Würzburg, a consortium embarks on the NaKlaR project to enhance the efficiency and sustainability of sodium-ion batteries. The project, funded with over two million euros by the Federal Ministry of Education and Research (BMBF), aims to position sodium batteries as a powerful and sustainable alternative to conventional lithium-ion batteries.
Sodium Batteries: An Earth-Friendly Alternative
Sodium-ion batteries present a promising alternative due to the abundance of sodium on Earth, making them environmentally friendly. Unlike lithium batteries, sodium batteries eliminate the need for scarce resources such as lithium, cobalt, and copper. However, their drawback lies in lower energy density, making them ideal for stationary energy storage and smaller vehicles used for shorter distances.
NaKlaR Project Objectives
Coordinated by Dr. Guinevere Giffin and Professor Maik Finze from the University of Würzburg, the NaKlaR project targets several key objectives:
- Enhancing Efficiency: The project aims to boost the energy density of sodium batteries, making them more competitive with lithium-ion counterparts.
- Sustainability Optimization: By refining the production process, the project focuses on improving the overall sustainability of sodium batteries. This includes attention to recyclability from the development stage.
- Innovative Electrode Production: The team aims to produce battery electrodes sustainably, exploring alternatives to toxic organic solvents. This includes efforts to replace solvents with water, although challenges related to water presence in electrodes must be addressed.
- High-Performance Electrolytes: New electrolytes that remain stable in the presence of water molecules are crucial. Electrolytes are vital in transporting sodium ions through the battery.
Industry Collaboration and Advisory Board
The NaKlaR project benefits from an industrial advisory board, ensuring alignment with industry interests. Collaborating with companies like E-lyte Innovations GmbH and Leclanché GmbH, the project promotes a regular exchange of information between research organizations and industry.
A Sustainable Future for Batteries
Navigating the complexities of battery systems, NaKlaR is committed to pushing the boundaries of sodium-ion battery technology. From sustainable electrode production to the development of high-performance electrolytes, the project strives to position sodium batteries as a frontrunner in the transition to greener energy storage solutions.
