The project main goal of SIMBA 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.
Uniresearch Role

Uniresearch was hired by the coordinator of the project to review the grant application process based on Uniresearch’s expertise. After approval of the project, Uniresearch has been assigned the task of project management facilitator and leader of the dissemination Work Package.

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.
