A MOF is employed as a template and carbon resource for the synthesis of porous carbon-coated CuCo<sub>2</sub>O<sub>4</sub> concave polyhedra, exhibiting an excellent capacity cycling reversibility.
Abstract Based on the structural characteristics of anodes lithium-ion batteries, an improved Hummers’ method is proposed to recycle anode materials spent batteries into graphene. In order effectively separate active material from copper foil, water was selected as ultrasonic solvent in this experiment. further verify whether lithium ions exist material, carbon powder, it digested by microwave digestion. ICP-AES then used analyse solution. It found that were almost non-existent powder....
One-dimensional Ag-Fe3O4 core-shell heteronanowires have been synthesized by a facile and effective coprecipitation method, in which silver nanowires (AgNWs) were used as the nucleation site for growth of Fe3O4 aqueous solution. The size morphology control achieved simple adjustments reaction conditions including FeCl3/FeCl2 concentration, poly(vinylpyrrolidone) (PVP) temperature, time. It was found that shell thickness could be tuned from 6 to 76 nm with variation between nanopheres...
Abstract Lithium‐ion batteries (LIBs) are currently widely applied in many aspects of life, but with the development, capacity lithium‐ion can no longer meet needs. One dominant factors to restricting LIBs is cathode materials. Among derivatives spinel LiMn 2 O 4 (LMO), LiNi 0.5 Mn 1.5 (LNMO) has become one research promising materials current due its high working voltage (4.7 V) and large theoretical specific (147 mAh g −1 ). However, short cycle life LNMO during electrochemical process...
Significant progress in PbS quantum dot solar cells has been achieved through designing device architecture, engineering band alignment, and optimizing the surface chemistry of colloidal dots (CQDs). However, developing a highly stable while maintaining desirable efficiency is still challenging issue for these emerging cells. In this study, by introducing an ultrathin NiO nanocrystalline interlayer between Au electrodes hole-transport layer PbS-EDT, resulting CQD cell improved from 9.3 to...
Surface phase with ion or electron conductor is essential for the improved rate capability of mostly electronically insulating LiFePO4 materials only one-dimensional Li+ transport. Here, a surface conductive phase, created through Zr4+ doping in Li-excess LiFePO4, forms synergy carbon coating layer to facilitate transportation, which greatly performance materials. The appropriate amount exhibits excellent 125 mA·h·g−1 at 20 C and stable capacity retention 98.5% 200 cycles 5 C. finding...
With the development of lithium ion batteries (LIBs), further increasing energy densities is urgent. Graphene, with excellent chemical stability, high conductivity, and light weight, an ideal material to improve battery density by replacing traditional metal current collectors. Accordingly, we report a large-size (120 mm × 120 mm) graphene assembled film (GAF) crystallinity, electrical conductivity ((2.30 ± 0.06) 105 S m–1) ultralight weight (3.18 mg cm–2). The electrode/GAF interface has...
The NaxMnO2 (x<0.44) material with a T‐type tunnel phase shows excellent cycling performance, but low initial specific capacity. (x>0.6) P2‐type exhibits high capacity, yet poor performance. Layer‐tunnel hybrid materials have served as cathode for sodium‐ion batteries due to the integration of capacity and superior Herein, we synthesize sodium manganite composites containing small amount layered in Na0.44MnO2 using citric acid dispersant. can promote transition T‐P2 contribute uniform...
