When the battery room in MF Ytterøyningen caught fire and subsequently exploded last year, large amounts of highly toxic chemicals were formed, imposing a threat to both humans and the surrounding environment. Current high-energy Li-ion batteries are based on cathode materials that contain cobolt. For next generation high energy batteries one of the main routes includes the introduction of a cobolt-free cathode material. This material operates at higher voltages, which gives the potentially higher energy density. Unfortunately, it has challenges with respect to stability. Our innovation represents an enabling technology for the use of new cathode materials and new electrolytes for the next generation of batteries. The project has demonstrated a current collector with improved corrosion resistance. The current collector?s pH window was determined and mechanical strength tests were performed. The targeted reduction in tensile strength could unfortunately not be achieved. Hence, the recommendation is to establish an inter disciplinary research project as a next step.

The technology will increase the performance of batteries and decrease the risk of usage. This has the potential of contribute to the de-carbonization of the energy sector. The improved safety and performance of batteries will increase the adoption rate of sustainable electric transportation infrastructure. Environmental footprint of batteries will be improved by enabling of electrolytes not forming HF. This will enable the introduction of high energy, cobolt-free cathodes, reduce the content of fluor, and ease the recycling of Li-ion batteries.
