Owing to their high theoretical specific capacity and low cost, lithium- manganese-rich layered oxide (LMR) cathode materials are receiving increasing attention for application in lithium-ion batteries. However, poor lithium ion electron transport kinetics plus side effects of anion cation redox reactions hamper power performance stability the LMRs. In this study, LMR Li1.2Mn0.6Ni0.2O2 was modified by phosphorus (P)-doping increase Li+ conductivity bulk material. This achieved interlayer...
Lithium manganese phosphate (LiMnPO 4 ) has been considered as promising cathode material for electric vehicles and energy storage. However, its durability capability still face challenges. The first‐principles calculations are a powerful tool to explore the fundamentals of LiMnPO materials. Hereby, recent advances prospects in application boosting lithium‐ion batteries analyzed reviewed. Based on results from density functional theory calculation experimental research verification,...
Na4Fe3(PO4)2P2O7/C (NFPP) is a promising cathode material for sodium-ion batteries, but its electrochemical performance heavily impeded by low electronic conductivity. To address this, pure-phase Mo6+-doped Na4Fe3−xMox(PO4)2P2O7/C (Mox-NFPP, x = 0, 0.05, 0.10, 0.15) with the Pn21a space group successfully synthesized through spray drying and annealing methods. Density functional theory (DFT) calculations reveal that Mo6+ doping facilitates transition of electrons from valence to conduction...
The effect of superficial gas velocity and structural parameters plate (perforated tongue plate) on the hydrodynamics column are studied in a multi‐stage bubble column, with 2000 mm height 282 diameter by using electrical resistance tomography (ERT) technique computational fluid dynamics (CFD). According to results, ERT CFD techniques can be well applied measurement estimation gas–liquid two‐phase processes. holdups, radial distribution holdup cap strongly depend operating condition tray...
A proportional-integral extended state observer (PI-ESO) of nuclear reactors is proposed for disturbance estimation, driven by the measurement errors neutron flux, primary coolant temperatures at reactor inlet and outlet, as well their integrations. This PI-ESO can provide a globally asymptotically bounded estimation not only process variables, including normalized flux precursor concentrations average fuel assemblies coolant, but also total disturbances in channels kinetics thermal...
Due to the complementarity between intermittent renewable energy (IRE) and nuclear, it is attractive interconnect them supply clean consistently continuously in a large-scale. The flexibility of for integrating IRE can be provided by actively adjusting electric power output nuclear cogeneration plants (NCPs), which induces frequent redistribution main steam turbine process. For redistribution, necessary guarantee stability grid frequency pressure, heavily relies on flexible control NCPs. In...
Recently, increasing attention has been paid to nuclear power control with the appeals of clean energy and demands regulation integrate into grid. However, a system is discrete-time (DT) nonlinear complicated system, where parameters entangle intrinsic states. Furthermore, need for huge computational ability due high-level order property in reactor model causes many difficulties industries.
