Figure 5 illustrates the effect of Li-cobalt (LiCoO2) that is first cycled at room temperature (RT) and then heated to 130C (266F) for 90 minutes and cycled at 20, 50 and 100 percent SoC. This allows them to charge below freezing at a reduced charge C-rate. Below 5C, the charge current should be reduced, and no charging is permitted at freezing temperatures because of the reduced diffusion rates on the anode. Are these ambient temperatures or actual internal battery temperatures? With a voltage of 3,92Volt (50%) without damage the battery? Older battery technologies, such as lead acid and NiCd, have higher charging tolerances than newer systems, such as Li-ion. Published 5:44 AM PDT, July 20, 2023.
