Motivation
Successful implementation of the energy transition requires innovative and efficient electrochemical energy storage systems for electromobility and the associated charging infrastructure. Currently, Li-ion batteries (LIB) are the preferred solution for both vehicle propulsion and stationary storage (ESS), accounting for more than 90% of the global grid market. Due to the high power density and resource availability of Li, Co and Ni (batteries), it is essential to concentrate their use on the electromobility sector. In order to release these resources to power vehicles, the infrastructure requires sustainable, cost-effective and safe solutions that avoid critical raw materials. Due to material availability, material costs and theoretical specific energy density, rechargeable alkaline zinc manganese dioxide battery systems (ZMB) are a promising alternative to LIB solutions.
Project Goals
ORRCABATT's main objective is to optimize the design and manufacturing processes of rechargeable alkaline ZMBs through improved electrode materials, cell components and battery formats, including a battery management system. From the outset, all life cycle phases (raw material extraction, material processing, component and battery production, use and battery recovery/recycling) are taken into account. The ORRCABATT project will demonstrate the benefits of using ZMB in electric vehicle charging infrastructure and other stationary power storage applications over Li batteries over a period of 36 months. To this end, the cell design of the zinc-manganese energy storage device will be transferred from the laboratory scale to the industrial scale. Using the method of life cycle assessment, the project will identify suitable materials and develop tailor-made recycling routes. The holistic approach will enable a comprehensive assessment of environmental impact right from the start and tailored recycling in the future.
