Such conversion provides a high energy density, but normally lasts only for 50–100 charge–discharge cycles, well below what is needed for a practical electric vehicle.
1. Introduction. New energy electric vehicles are gradually developing due to their advantages such as low energy consumption and less pollution (Xu, 2021, Al-Zareer, 2020, Shelkea, 2022, Zhang et al., 2022).As the most important component of new energy electric vehicles, lithium batteries play a key role in the conversion of chemical and …
Self-discharge of batteries is a natural, but nevertheless quite unwelcome, phenomenon. Because it is driven in its various forms by the same thermodynamic forces as the discharge during intended operation of the device it can only be slowed down by impeding the reaction kinetics of its various steps, i.e. their respective …

Graphite as anode materials: Fundamental ...
Graphite is a layered crystal formed of sp 2 hybrid carbon atoms linked by van der Waals forces and π-π interaction. Carbon atoms are arranged hexagonally and extend in two dimensions [8].Graphite layers are stacked in ABAB or ABCABC sequence, as shown in Fig. 2 (a) and (d). Natural graphite is dominated by ABAB sequence …
