Unlocking Failure Mechanisms and Improvement of Practical Li–S Pouch Cells Through in Operando Pressure Study (adv. Energy Mater. 7/2022)

Li–S Batteries In article number 2103048, Bin Li and co-workers report the results of an operando pressure study on a practical Li–S pouch cell, which reveals the role of pressure and the failure mechanisms due to poor wetting. Li metal anode degradation can also be diagnosed in real time. These results shed light on the rational design of high-energy density Li–S batteries and materials development at the pouch cell level.
