The global challenge of performance characterization – time for a new standard in solid-state battery development
Lecture
Solid state batteries
Characterization methods

One of the biggest bottlenecks in scaling up new battery technologies, still even today, is the fact that there is no standard way of testing the electrochemical performance of battery materials. Unreliable, hard to reproduce results, the typical characterization methods employed nowadays cripple the entire energy storage field and slow down the essential technology transfer from academia to industry.

This needs to change! One of the main identified drivers for data quality, is the test equipment used and the conditions under which battery testing is performed. It is fundamental for performance data acquisition, that the researcher can access and precisely control of relevant parameters. The classical Coin Cells and home-built Swagelok setups, typically settled at the basis of all battery materials tests do not provide the necessary control options for R&D on solid-state battery materials. It’s time to rethink how we do fundamental battery R&D.

In this presentation we will analyze latest studies on performance data quality, essential protocols and present a clear pathway on how to achieve a worldwide standard for solid-state battery testing – to finally eliminate this burden, holding us back from unraveling the best possible, sustainable battery.
