Batteries are important components for future transports, primarily for electrically powered vehicles. Volumes are expected to be substantial, making it important that the materials and manufacturing methods are environmentally friendly from the start.
We have considerable knowledge of battery manufacture at Swerea. Research and development take place in two areas – structural batteries and environmentally friendly lithium batteries.
Swerea's research in structural composites is both exciting and pioneering. By combining materials that can handle a structural load and simultaneously store energy, we have developed a multi-material with revolutionary application areas.
As an example, a car's chassis can serve as a battery, which can reduce its total weight and reduce energy consumption.The principle is the same as for a conventional battery with the exception that the electrodes are sufficiently robust to bear loads. Research has been conducted in collaboration with the Royal Institute of Technology and the Chalmers Institute of Technology, and involves several researchers and post-graduate students.
Environmentally friendly lithium batteries
The manufacture of cathode materials for lithium-ion batteries is dominated by solvent-based processes with significant health and environmental complications. Large-scale handling of the toxic substances is also very expensive.
Swerea has many years of experience in developing environmentally friendly, water-based systems for various types of ceramic pastes and this knowledge can be applied in developing paste for lithium-ion batteries.
