Customer ServiceOverall, SRXTM data suggest that low current density combined with electrolyte flow achieves the broadest curvature angle, smoothest surface morphology, thinnest deposition layer, and least dendrite formation, maintaining a more stable surface after 20 cycles compared to other experimental conditions. This configuration reduces concentration gradients
Customer ServiceAs the number of cycles increases, the increase in DC internal resistance indicates that under low-temperature environments, the deposited lithium causes the thickening of the SEI film during battery cycling, and some lithium deposits are lost in a "dead lithium" manner, resulting in battery capacity fade.

Customer ServiceBy understanding battery cycle count, you can take steps to prolong the life of your battery and maximize its performance. But what exactly is a battery cycle count?

Customer ServiceThe phenomenon of reduced internal resistance and up-shift of the charging curve was found during the early cycle stages (0th-20th cycle). The influence of low-temperature cycle on battery was analyzed by the increment capacity analysis (ICA); the fast decreasing intensity of ①*II showed sharp loss of lithium ions.
If the current is too low, it will result in the formation of fewer but larger crystals in the perspective of total discharge, which in the case of incomplete charging will result in, as in the previous cases, a loss of active material and a reduction in the battery capacity.
In , the effect of current rate on the aging is analyzed cycling the battery at different current rates. Anyway, even if the tests are performed in a climatic chamber at 25 °C, the temperature of the battery cell is not controlled and will change with the current rate due to its internal losses.
In a low-temperature environment, the battery’s internal polarization resistance is higher, leading to a large amount of heat generation during high-rate discharge, which enhances the battery’s internal activity and causes the voltage to rise. However, the amount of power that can be discharged in a low-temperature environment is reduced.
In the literature, lithium plating is reported to be the main cause of lithium-ion batteries aging at low temperature and/or at high charge rate. Lithium carbonate compounds can be formed in case of contact between the metallic lithium and the electrolyte on the surface of the SEI.
As can be seen, cycle 2 has the most destructive influence on the battery. After only 30 cycles the battery reached end of life. In cycle 1 the battery reached end of life after 76 cycles. That result led to the conclusion that batteries tested in 1st set might all work in bad recharges since their degradation process was progressing very fast.
