Web1 Introduction. Lithium-ion batteries (LIBs) are currently considered the most attractive option to power hybrid- and all-electric vehicle. 1, 2 However, the user acceptance is still quite limited, mainly due to high costs, safety concerns, unsatisfactory fast charging, and insufficient range capabilities. Furthermore, the wide-spread adoption of electric vehicles … WebBLG and measured ultrafast Li diffusion coefficient of up to 7×10−5 cm2 s−1 at room temperature [27]. Theoretically, there have been some previous studies on Li diffusion in graphene or graphite [28-37]. Tachikawa calculated a Li diffusion coefficient (~10−10 cm2 s−1) on a fluorine terminated graphene surface at room temperature [28]. K.
