ABSTRACTThe electrochemical storage performance of anatase TiO2 nanotubes (NT) is compared to the performance of TiO2 nanotubes covered by sulfur. Charge/discharge curves and cycling performance of TiO2 NT with and without sulfur deposition with respect to lithium anodes are demonstrated in electrochemical test cells. At 0.5C cycle rate the TiO2 NT exhibited a first cycle specific charge/discharge capacity of 180/155 mAh/g, whereas the TiO2 NT deposited with sulfur showed a remarkably higher performance at 0.5C cycle rate with first cycle charge/ discharge specific capacities of 258/260 mAh/g and a coulombic efficiency of 98%.

Li0.95Na0.05Ti2(PO4)3/C nanocomposite was prepared by sol-gel method.The structure and morphology of the samples were characterized by XRD, SEM which showed the particles had typical NASICON structure and diameter range from 400~500nm. The electrochemical performance were tested by cyclic voltammetry and galvanostatic charge–discharge. Results show Li0.95Na0.05Ti2(PO4)3/C nanocomposite exhibitsmuch better electrochemical performance than bare Li0.95Na0.05Ti2(PO4)3.

LiV3O8 nanorod material was prepared by a simple sol–gel method. The electrochemical properties of the as-prepared LiV3O8 in 0.5 M Li2SO4 aqueous electrolyte were studied through cyclic voltammograms (CV) and discharge–charge measurements. Experiments show that this nanorod material can deliver the capacities of 72, 62 and 53 mAh/g at 20, 50, 100 mA/g, respectively. After 50 cycles, it can maintain 64, 47 and 40 mAh/g, corresponding to 88%, 76% and 77% of the initial capacities, which suggest that this nanorode material presents good cycling performance as anode material for aqueous rechargeable lithium batteries.

Abstract In this article, proton exchange membranes (PEMs) are used as separators for lead-acid batteries. Ion migration experiments are conducted to prove the efficacy of PEMs in blocking the passage of antimony ions. The cells are then assembled into a battery to undergo charge–discharge, life cycle, and electrolyte loss testing. The results show that PEMs are effective at reducing the migration of antimony ions from the cathode alloy grid to the anode while suppressing hydrogen formation and electrolyte loss, which greatly improves coulombic efficiency and cycle life of the battery.
