Message: [QUOTE="bwegner, post: 101495, member: 2139"] To sugeruję nie wycinać z kontekstu. Dlatego całość jest tu, pogrubiłem to co ma znaczenie (i co też powoduje że na figure 10, żółta krzywa przecina się z czerwoną): "It can be seen that the influence of the SOC level during storage was different at different time ranges. Before the battery cells reached the EOL (i.e., 20% capacity fade), higher SOC was also accompanied by a higher rate of capacity fade. The reason is similar to the effect of temperature. A higher SOC will accelerate the side reaction, causing the decomposition of the electrolyte and the increase of the SEI film. In addition, at higher SOC levels where the graphite anode is lithiated more than 50%, the low anode potential accelerates the loss of lithium ions [6,28]. On the contrary, from the perspective of very long-term aging (i.e., capacity fade higher than 20%), an SOC level in the mid-SOC range (i.e., around 50% SOC) will speed up the degradation rate of the battery. This may be because a SEI film with high stability is formed, [B]which effectively prolongs the battery life stored at 90% SOC level [1]."[/B] [/QUOTE]
