Owing to safety issues of liquid-containing polymer electrolytes, lots of efforts have been devoted to developing the liquid-free all-solid polymer electrolytes (SPEs) for lithium or sodium-ion batteries. However, the SPEs suffer from a lack of the ionic conductivity and mechanical performances for the applications, and therefore, numerous strategies have been reported to overcome the disadvantages. Among them, the preparation of composite polymer electrolyte (CPE) has been regarded as one of the most efficient and facile approaches due to the convenient fabrication procedure and easily tailorable properties for both ionic conductivity and mechanical durability. In the current study, the all-organic CPE was prepared using cellulose nanocrystals (CNCs) as a reinforcing agent and poly(vinylidene fluoride) (PVDF) as a polymeric matrix. The reinforcing effects of CNCs on the ionic conductivity and rheological behaviors were evaluated in terms of the filler loading of 0-30 wt%. |
