This study reports a facile synthesis of ZnO microrods using chemical bath deposition (CBD) for anode materials of lithium-ion batteries (LIB). During the synthesis, we controlled the uniformity, the density, and the diameter growth of ZnO microrods in order to find the optimum conditions. In particular, the effects of annealing temperature on the ZnO microrod morphology, structure, and electrochemical...
CoO composite materials had attracted wide attention due to their potential application in lithium ion batteries (LIBs). We report a green and novel solution method for making pristine Co3O4 and mixed phase CoO@Co3O4@C composite anode electrodes in LIBs. The anode materials characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD diffraction pattern reveals that composite...
In order to reduce the weight of the lithium-ion battery and increase its capacity, the copper foil as a conventional current collector is completely abandoned, and a novel ultralight negative electrode prepared by freeze-drying technology and carboxymethyl cellulose (CMC) has a 3D sponge-like structure. Further, graphite is employed as an electrode material. X-ray diffraction and Raman spectroscopy...
Lithium-ion capacitors (LICs) are an optimal candidate to bridge the gap between lithium-ion battery and conventional supercapacitors as the promising electrochemical energy storage devices with fast charging-discharging capability and long cycle life. A three-electrode LIC pouch cell is fabricated employing an electrochemically driven lithium pre-doping method. Active materials of cathode and anode...
Manganese oxides have always been considered as promising high-performance electrodes due to the high specific capacity, low cost, and environmental benignity. Here, we have synthesized a hierarchical manganese oxide hydrate for superior lithium-ion battery anode via a facile liquid precipitation reaction and low-temperature heat treatment. The 2D layered structure with hydration water provides a...
