IBU-tec advanced materials AG has made progress in the development and production of cathode active materials for sodium-ion batteries. According to the German company, the production of manganese oxide has been successfully scaled up to 100 kilograms, while further scaling-up is planned. At present, the cycle life of the cathode is being tested in full-size cells. Potential applications include stationary energy storage and electric vehicles.
Sustainable, safer, and cheaper
Sodium-ion batteries have a lower energy density than lithium-ion batteries but advantages in terms of environmental friendliness, cost and safety. IBU-tec particularly emphasizes the potential of sodium-ion batteries for lower production costs on an industrial scale. This is said to be achieved through the use of more inexpensive materials such as aluminum and sodium.
Project on sodium iron phosphate batteries
IBU-tec has also launched a research project to develop a cathode active material based on sodium iron phosphate for sodium-ion battery systems. Carried out together with Jungheinrich AG and UniverCell Holding, the joint project’s goal is to produce an active material on a scale of 20 to 50 kilograms, which will later be processed into electrodes and used in battery modules. The companies hope the new battery system will be able to replace lead-acid batteries in the long term. Development is expected to be completed by the end of 2026. It is being funded by the German Federal Ministry of Education and Research with approximately two million euros.
