A new approach from PSI to improve battery performance offers the industry new opportunities for efficient and long-lasting energy storage.
A research team from the Paul Scherrer Institute (PSI) has developed an innovative process that significantly enhances the electrochemical performance of lithium-ion batteries. Initial tests with modified batteries have shown promising results. This patent-pending development provides the industry with new possibilities to further increase the efficiency of batteries, particularly for electric vehicles.
Lithium-ion batteries are crucial for decarbonization, and research is ongoing worldwide to optimize their performance. While increasing the operating voltage boosts energy density and overall performance, voltages above 4.3 volts have previously damaged the cathode surface. PSI has developed and patented a method that uses a protective layer to stabilize the voltage up to 4.8 volts. The process utilizes trifluoromethane (CHF3), a byproduct of plastics production, which is converted into a lithium fluoride protective layer. This layer stabilizes the cathode and improves capacity retention. Tests showed a 30% lower impedance and over 94% capacity retention after 100 charge cycles, compared to 80% for conventional batteries. The process also recycles trifluoromethane, contributing to the circular economy and reducing ecological impact.
This technology offers significant advantages for the industry, providing new opportunities for companies to optimize their batteries while contributing to a sustainable energy transition. It is particularly relevant for mobile applications, such as in the automotive industry, as well as for manufacturers of high-performance batteries used in aviation, shipping, and stationary energy storage. Companies in the electronics sector that rely on durable, high-performance batteries could also benefit from the enhanced battery performance.
In case you are interested in this technology and would like to know if this process could also be relevant for your company, we look forward to hearing from you!
