Tio2 Nanobelts

Titanium dioxide (TiO2) has been widely investigated as the electrode material for lithium ion batteries (LIBs), due to its low cost, small volume expansion, and high environmental friendliness. However, the fading capacity and short cycle life during the cycling process lead to poor cycling performance. Herein, multilayer TiO2 nanobelts with a high specific surface area and with many pores between nanoparticles are constructed via a simple and large-scale approach. Benefiting from the multilayer nanobelt structure, as-prepared TiO2 nanobelts deliver a high reversible capacity, strong cycling stability, and ultra-long cycle life (~185mAhg−1 at 500mAg−1 after 500 cycles) as electrode materials for LIBs.

Transfer Resistance

Metal-organic frameworks (MOFs) have recently emerged as promising electrode materials for lithium-ion batteries (LIBs). However, poor electrical conductivity in most MOFs limits their electrochemical performance. In this work, the integration of flaky cobalt 1,4-benzenedicarboxylate (Co-BDC) MOF with conductive polypyrrole (PPy) nanofibers via in-situ growth strategy was explored for developing novel anode materials for LIBs. Electrochemical studies showed that PPy/Co-BDC composites exhibited enhanced cycling performance (a reversible capacity of ca. 364 mA h g–1 at a current density of 50 mA g–1 after 100 cycles) and rate capability, com- pared with the pristine Co-BDC. The well dispersion of Co-BDC on polypyrrole nanofibers and the decrease in charge-transfer resistance of the composite electrodes accounted for the improvement of electrochemical properties.
