TU Delft researchers have made significant strides in the development of batteries that offer faster charging, stable storage, and are made from sustainable materials. The research, recently published in Nature Sustainability, focuses on the creation of a new positive electrode that provides a potential cheaper alternative to lithium-ion batteries. This breakthrough not only addresses the high CO2 footprint associated with lithium-ion batteries but also reduces reliance on rare materials.
In a previous paper published in Nature Energy, researchers Marnix Wagemaker and Alexandros Vasileiadis collaborated with researchers from the Chinese Academy of Sciences to create fast-charging Na-ion batteries. The recent research expands on this work by improving the negative electrode and emphasizes the use of organic materials that are widely available, reducing dependency on rare materials that are not sourced from Europe.
The Delft researchers have also made significant advancements in cathode design. Their latest article, titled “Fast-charge high-voltage layered cathodes for sodium-ion batteries,” builds upon design principles presented in a 2020 paper published in Science. Through these design principles, they have developed a material that combines high energy density with fast charging capabilities. Furthermore, this material demonstrates remarkable structural stability during charging and discharging, resulting in a longer lifespan. Notably, it also eliminates the need for cobalt, a commonly used component in lithium-ion cathodes.
With increasing knowledge and understanding of these battery materials, the researchers are now moving towards the next phase of their sustainable battery technology project. This project, supported by the Growth Fund, aims to expand the research on both Li-ion batteries and Na-ion batteries. The ultimate goal is to apply this technology to national and European markets, paving the way for more sustainable energy storage solutions.
Through their innovative approach and focus on sustainable materials, TU Delft researchers are driving the development of batteries that offer a promising alternative to lithium-ion. By addressing the limitations of current battery technology, these advancements have the potential to revolutionize the energy storage industry and contribute to a greener future.
