Project HighSpin to develop cobalt-free batteries
The overall objective is to increase the energy density and power density of batteries in order to meet the requirements of electromobility. The aim is to develop a cobalt-free cell that has an anode made of silicon/graphite and a cathode made of lithium-nickel-manganese oxide. The plan is to realise a cell with an energy density of 390 Wh/kg and a service life of at least 2,000 charging cycles.
According to the researchers, resource-saving production, second-life applications and efficient recycling also play a decisive role for a sustainable life cycle of the battery. The scalability of manufacturing from laboratory to industrial scale is also being examined.
The main objective of the research project is “to produce a cell with an energy density of 390 Wh/kg and a lifespan of at least 2000 cycles”. This includes everything from material development and harmonization of the full cell chemistry with the cathode, anode and electrolyte. To increase power density, “innovative 3D electrode design” is also part of the research work.
Once the designs are approved, the project will test the batteries by installing the cells in module demonstrators with high energy density, power density and long-lasting durability for road vehicles as well as aircraft. “A flexibly deployable module is being developed especially for aeronautical applications.”
