Boosting the kinetics of PF6-into graphitic layers for the optimal cathode of dual-ion batteries:The rehearsal of pre-intercalating Li+
文献摘要：
Large anions exhibit slow diffusion kinetics in graphite cathode of dual-ion batteries(DIBs);particularly at high current density,it suffers severely from the largely-reduced interlayer utilization of graphite cath-ode,which as a bottleneck limits the fast charge application of DIBs.To maximize interlayer utilization and achieve faster anion diffusion kinetics,a fast and uncrowded anion transport channel must be estab-lished.Herein,Li+was pre-intercalated into the graphite paper(GP)cathode to increase the interlayer spacing,and then hosted for the PF6-anion storage.Combined with theoretical calculation,it shows that the local interlayer spacing enlargement and the residual Li+reduce the anion intercalation energy and diffusion barrier,leading to better rate stability.The obtained GP with Li+pre-intercalation(GP-Li)elec-trode exhibits a discharge capacity of 23.1 mAh g-1 at a high current of 1300 mA g-1.This work provides a facile method to efficiently improve the interlayer utilization of graphite cathode at large currents.
