As an important Co-free and Ni-rich layered oxide, LiNi0.9Mn0.1O2 (NM91) has garnered significant interest as a promising cathode material for lithium-ion batteries. Despite its attractively high specific capacity, the intrinsic structural instability poses great challenge to electrochemical performances, especially cycling performance. In this work, we circumvent issue of NM91 through high-valence Nb doping. Our findings reveal that Nb5+ dopants were successfully incorporated into lattice...
High-energy-density lithium-ion batteries have great need for cathode materials with exceptional specific discharge capacity. Li3V2O5 shows potential because of its high capacity (e.g., 266 mA h g-1 at 0.1 A g-1). However, low-lying voltage plateau (∼0.6 V vs Li+/Li) restricts use exclusively to anode applications. This work presents the first time development as a high-energy-density material through Ni doping. Structural analysis reveals that Ni-doped forms cation-disordered rock-salt...
Covalent organic frameworks (COFs) have been regarded as promising cathode materials for lithium batteries. However, they generally show low practical capacity. Here we report the design, preparation, and battery application of a highly crystalline two‐dimensional truxenone‐based COF (TRO‐BT‐COF) with rich redox active sites, realizing high In‐situ characterizations theoretical calculations indicate that lithiation reaction proceeds successively on C=O C=N groups TRO‐BT‐COF. One ring...
Iron oxide dry desulfurization is one method for the removal of hydrogen sulfide. This work investigates physicochemical properties and performance oolitic hematite upon at high temperature. The effects particle size, sulfidation temperature, gas speed on were evaluated in a fixed bed reaction, also regeneration cycle experiment was conducted. Characterization techniques such as X-ray fluorescence, diffraction, scanning electron microscopy, photoelectron spectroscopy employed to illustrate...
