WebElectrochemical impedance spectroscopy (EIS) measurements of lithium-ion cells at low temperatures showed that the cell impedance is mostly dominated by the charge transfer resistance. 124 This finding is in line with the study by Wang et al. 125 who investigated the low-temperature performance of graphite and mesocarbon microbeads (MCMBs) by ... WebGraphite anodes work in a potential range of 50–200 mV versus Li/Li + with a specific capacity of about 350 Ah kg −1 at good price, stability, and safety, but moderate power. On charging highly graphitized carbon, the potential drops rapidly to near 0.8 V versus Li/Li +, where the potential remains nearly constant.
