摘      要：The increasing demand for short charging time on electric vehicles has motivated realization of fast chargeable lithium-ion batteries(LIBs).However,shortening the charging time of LIBs is limited by Li^(+)intercalation process consisting of liquid-phase diffusion,de-solvation,SEI crossing,and solid-phase ***,we propose a new strategy to accelerate the de-solvation step through a control of interaction between polymeric binder and solvent-Li^(+)*** this purpose,three alkali metal ions(Li^(+),Na^(+),and K^(+))substituted carboxymethyl cellulose(Li-,Na-,and K-CMC)are prepared to examine the effects of metal ions on their *** lowest activation energy of de-solvation and the highest chemical diffusion coefficient were observed for ***,Li-CMC cell with a capacity of 3 mAh cm^(-2)could be charged to95%in 10 min,while a value above85%was observed after 150 ***,the presented approach holds great promise for the realization of fast charging.
