How to build better Solid State Batteries - A practical guide for lab scale cells.

Solid-state batteries are gaining attention and focus from the entire battery industry due to their potential for significant improvements in battery technology. However, evaluating the electrochemical performance of materials and solid-state cells can be a complex challenge. One crucial aspect is the “human factor” in the cell assembly processes.

Together with the experts from hte GmbH - a renowned high-throughput experimentation company, we gathered over 10 years of experimental knowledge into a white paper, describing best practices and pitfalls to avoid when assembling solid-state battery cells in the lab. We hope to provide valuable input for researchers around the world to improve the reliability and data quality of experimental results.

This white paper provides a comprehensive, step-by-step guide for researchers and engineers aiming to build and evaluate lab-scale solid-state batteries (SSBs). Recognizing the lack of standardization in the field, the authors share practical knowledge, best practices, and common pitfalls gathered from years of academic and industrial experience. The document begins by outlining the unique challenges of SSB chemistry, including the critical roles of pressure, moisture sensitivity, and interface engineering.

It then explores cell casing selection, assembly protocols, and strategies for ensuring precision in component drying, stack compression, and material homogeneity. Detailed guidance is provided for assembling full cells, including proper sequencing, handling techniques, and pressure application during testing. The guide also highlights typical assembly errors and their impact on performance, offering troubleshooting advice and a cause-effect matrix to assist in diagnosing issues.

A dedicated section on electrochemical testing methodologies—including impedance spectroscopy, charge/discharge cycling, reference electrodes, and scalability assessments—equips readers with the tools to interpret results accurately and ensure reproducibility. Overall, this practical guide serves as a valuable resource for advancing the quality, reliability, and comparability of SSB research.
