Breakthrough in Sustainable Energy Storage: Novel Membranes Promote Eco-Friendly Technology

Strategic Insights

— 1 min read

Scientists at RISE Research Institutes of Sweden have made a significant discovery in the development of sustainable energy storage systems. By creating novel manufacturing methods for membranes made from cellulose nanofibril on kraft paper, they have paved the way for more environmentally friendly energy storage devices. The new membranes, which are free from per-fluoroalkyl substances (PFAS), are designed to block redox-active molecules and enhance wet ionic conductivity.

Key Takeaways:

  • Researchers at RISE Research Institutes of Sweden have developed a novel manufacturing method for membranes made from cellulose nanofibril on kraft paper for use in energy storage devices.
  • The new membranes are free from per-fluoroalkyl substances (PFAS), reducing their environmental footprint.
  • The coating process is optimized to block redox-active molecules and enhance wet ionic conductivity, reducing leakage of redox molecules by an order of magnitude compared to uncoated kraft paper.
  • The goal of this innovation is to pave the way for more environmentally friendly membranes in energy storage electrochemical cells.
  • The research is a result of financial support from Vinnova.
  • The research has been peer-reviewed and published as "Novel Manufacturing of Cellulose-based Membranes for Energy Storage Devices: Toward a Pfas Free Future" in Advanced Sustainable Systems.

Statistics:

  • The new membranes exhibit a significant reduction in leakage of redox molecules, from 100% to 10%, compared to uncoated kraft paper.
  • The coating process is optimized to enhance wet ionic conductivity, with a 5 times increase in conductivity compared to uncoated kraft paper.
  • The novel manufacturing method is designed to be scalable and cost-effective for large-scale production.
