SIMBA | Sodium-Ion and sodium Metal BAtteries for efficient and sustainable next-generation energy storage

Original description

The project main goal is the development of a highly cost-effective, safe, all-solid-state-battery with sodium as mobile ionic charge carrier for stationary energy storage applications. To achieve this goal, several aspects need to be considered including material innovations, sustainable electrode and cell manufacturing, improved characterisation and understanding of the electrochemical processes. SIMBA has the ambitious and realistic goal to tackle these challenges and has formulated the following objectives: (1) Safer batteries with a novel Solid-State Electrolyte (SSE) (TRL3-5), by developing a new class of single-ion conducting polymers (SIPEs) and its production method. (2) Higher energy density and more durable anodes by developing materials up to TRL5 using sustainable manufacturing methods. (3) Low-cost and higher energy cathode materials, by developing ultra-low-cost Prussian White (PW) and high energy density layered oxides (P2/O3) up to TRL5. (4) Obtaining deep understanding of fundamental mechanisms incl. degradation phenomena, taking place at the Solid-Electrolyte-Interface (SEI) and within the battery components. (5) Demonstration of a scaled-up highly efficient 12V, 1Ah battery module incl. BMS to validate the re-use of materials, recyclability, performance, LCA, and potential for further development. Jointly this will result in a sodium-based battery demonstrating the improved performance, recyclability and sustainability, for a stationary energy storage use-case, including a detailed Total Cost of Ownership analysis.
