Front Cover: Mimicking Capacity Degradation in a Lithium Ion Battery Anode in Cells With a Li Metal Electrode: A Perspective on Advantages (Adv. Energy Sustainability Res. 2/2026)

Mimicking Capacity Degradation in a Lithium Ion Battery Anode Within the typical anode R&D in Li cells, the active Li loss (ALL) is not accounted and the fixed charge cut-off voltage/potential is sensitively prone to capacity fluctuations due to small overvoltage differences. When charging with “capacity cut-off”, which is defined by previous discharge capacity, ALL-reasoned capacity loss is considered; without the problematic voltage/potential charge cut-off. More details can be found in the Perspective by Lukas Stolz, Johannes Kasnatscheew, and co-workers (DOI: 10.1002/aesr.202500491).
