The Ni‐rich LiNi0.8Co0.10Mn0.1O2 (NCM811) cathode coated by combining with multi‐walled carbon nanotubes (MWCNTs) and polyimide (PI) produces a PI3‐NCM811 cathode, which markedly improves cycling stability and suppresses secondary crystal cracking. The initial discharge capacity of the PI3‐NCM811 cathode is 199.6 mAh g−1 between 2.8 and 4.3 V at 0.1 C @ 25 °C, which is slightly lower than that of...
Composite xLiFePO4 (LF)·yLi3V2 (PO4)3 (VP) carbon microspheres (CMSs) (LFVPC) with different (x:y) molar ratios were investigated for lithium-ion batteries (LIBs), synthesized using a hydrothermal and carbon reduction method. The microstructures and properties of the LFVPC composites were characterized via scanning electron microscopy, transmission electron microscopy, and X-ray diffraction methods,...
Barium tungstate (BaWO4) nanocrystals were successfully synthesized using a reverse microemulsion method. The effects of the molar ratio of water to surfactant (ωo), reactant concentration, and aging time on the size and morphology of the BaWO4 nanocrystals were investigated. The obtained products were characterized by scanning electron microscopy and X-ray diffraction (XRD). The experimental results...
In the past β-Ga2O3 nanopowders were usually prepared from gallium-based compounds via wet chemical processes. However, those wet chemical routes would lead not only to high cost, but also to the inevitable contamination of the targeted products from unexpected doping. In this work, the soluble salt-assisted route has been applied to prepare β-Ga2O3 nanopowders with a yield of 96.5 % through the direct...
