The latest work from the Chair of Electrical Energy Storage Technology, titled "Effect of the Mechanical Pressure on Rate Capability, and Expansion in Multilayer Pouch Cells with Silicon-Dominant Anodes" has been published in the ECS - The Electrochemical Society!

Highlights of the work include:

• Improved rate capability of silicon anodes compared to graphite anodes.
• Enhanced rate capability with lower temperature increases under higher mechanical pressures (e.g., 0.5 MPa), especially at higher C-rates (e.g., 3C).
• Pressure-dependent impedance influenced by contact resistance.
• Decreased anode thickness and porosity (quantified via pycnometer and mercury intrusion porosimeter measurements) with increasing pressures.

This research provides valuable insights into the effects of mechanical pressure on the performance of silicon-dominant anodes in multilayer pouch cells.
