Today lithium-ion is the main element of batteries, but they have an overall negative impact on the environment. To cater to this issue, scientists are developing longer-lasting, faster-charging batteries without rare materials. They are manufactured from sustainable materials and involve a new positive electrode design.

Researchers in TU Delft are currently working on creating batteries that possess the capacity to charge quickly and provide stable storage. Moreover, they plan to construct them from sustainable materials that are readily accessible. This innovation seeks to present a more cost-effective substitute to lithium-ion batteries, which consist of rare materials. Also, Li-ion batteries leave a significantly high carbon dioxide footprint.

Alexandros Vasileiadis and Marnix Wagemaker in collaboration with researchers from the Chinese Academy of Sciences, participated in the research. It was based on fast-charging Na-ion batteries and improvements made to the negative electrode. It’s possible to manufacture them using organic materials, which decreases reliance on rare materials not found in Europe.

Improved New Cathode

Delft researchers developed this new positive electrode for sodium-ion batteries that is based on design principles they previously discovered in 2020. These design principles have led to the development of a material that blends the advantages of two different structures:

  1. High energy density
  2. Fast charging

Additionally, the material’s structure undergoes gradual changes during charging and discharging, which significantly extends its lifespan. Moreover, it is free of cobalt, a common component in Li-ion cathodes.

What’s Next?

The growing knowledge about battery materials has paved the way for the next exciting development in sustainable battery technology – the Third Growth Fund project. This project will not only focus on researching Li-ion batteries but will also delve into Na-ion research at a national level. European Scientists Develop Longer Lasting Faster Charging Batteries Without Rare Materials and the research will be further expanded. This will enable this revolutionary technology’s application in national and European markets.
