Nicht das Halten eines bestimmten SOC ist die Ursache des Memory Effekts, sondern ganz generell Teilladungen.
Ganz grundsätzlich haben aber Lithiumzellen die nur teilgeladen werden einen weit höheren Energiedurchsatz bis 80 % Restkapazität, als Zellen die jedes Mal voll geladen werden.
The time that elapses between charging and discharging a battery plays an important role in determining the state of the battery at the end of these processes. Charging and discharging are processes that alter the thermodynamic equilibrium of the battery, and this equilibrium can be achieved after some time. Scientists have found that idling a sufficiently long period of time can be used to erase the memory effect. However, in accordance with the many particles model, this only happens under certain conditions. The memory effect only vanished if one waited a sufficiently long time after a cycle of partial charging followed by full discharge. In such cases, the two particle groups were still separated after the full discharge, but were found on the same side of the potential barrier. Thus, the separation disappeared, because particles attained an equilibrium state, in which they all had the same lithium-content. The memory effect remained however providing you waited after the partial charging and before the incomplete discharge. Here, the particles were on opposite sides of the potential barrier, and this prevented a reverse of their division into "lithium-rich" and "lithium-poor".
