dc.description.abstract | Low cycling stability is one of the most crucial issues in rechargeable batteries. Herein, we study the effects of a simple ultrasound treatment of graphite for the reversible (de)intercalation of a ClO4(-) anion from a 2.4 M Al(ClO4)(3) aqueous solution. We demonstrate that the ultrasound-treated graphite offers the improved reversibility of the ClO4(-) anion (de)intercalation compared with the untreated samples. The ex situ and in situ Raman spectroelectrochemistry and X-ray diffraction analysis of the ultrasound-treated materials shows no change in the interlayer spacing, a mild increase in the stacking order, and a large increase in the amount of defects in the lattice accompanied by a decrease in the lateral crystallite size. The smaller flakes of the ultrasonicated natural graphite facilitate the improved reversibility of the ClO4(-) anion electrochemical (de)intercalation and a more stable electrochemical performance with a cycle life of over 300 cycles. | en |
