Lithium-ion batteries (LIBs) have been widely used for portable electronics and electric vehicles; however, the low capacity in graphite anode limits improvement of energy density. Transition-metal selenides are promising material candidates due to their high theoretical controllable structure. In this study, we successfully synthesize a bimetallic transition-metal selenide nanocube composite, which is well embedded nitrogen-doped carbon matrix (denoted as CoNiSe2/NC). This shows excellent...
Driving the rapid regeneration of LiFePO 4 from spent lithium-ion batteries through one-pot mechanochemical activation, thus allowing for better environmental and economic returns.
An analytical solution is derived for dynamic response of a modified Timoshenko beam with an infinite length resting on visco-Pasternak foundation subjected to arbitrary excitations. The model employed further consider the rotary inertia caused by shear deformation beam, which usually neglected traditional model. By using Fourier and Laplace transforms, governing equations motion are transformed from partial differential forms into algebraic in domain. then converted time domain applying...
Abstract A unified nonlocal method (UNM) is developed to simulate discontinuous and multi‐physical coupling dynamic behaviors for quasi‐brittle materials. In the proposed method, momentum equations constitutive laws are capture fluid transport effect loading‐rate of general multiscale framework, which couples finite element (FEM), presented accelerate computational efficiency. The effectiveness accuracy this verified by comparing its results with experimental observations. Numerical examples...
In this paper, an analytical solution is proposed for longitudinal dynamic responses of long tunnels under arbitrary excitations. For the derivation, tunnel assumed as a Timoshenko beam resting on visco-Pasternak foundation. The theory employed to consider both effects shear distortion well rotary inertia tunnel, which are neglected by Euler–Bernoulli beam. foundation applied represent viscoelastic compressive and resistance soil. governing equations motion transformed from partial...
An improved constitutive model based on Timoshenko beam theory is proposed for bond-based peridynamics. The motion and force governing equations of the bond are established by introducing element to simulate interaction between particles including tension-rotation-shear coupling effects. Since axial displacement, transverse displacement relative rotation angle considered in model, it can overcome limitation Poisson’s ratio classical peridynamics model. Three kinds peridynamic...
As the key material in aqueous zinc-ion batteries (ZIBs), cathode can mitigate large coulombic interaction force generated after Zn2+ (de)intercalation and provide fast reaction kinetics, so exploring suitable is first issue for ZIBs to face market. Currently, many reports have been published about polyoxometalates (POMs) with multi-electron transfer capability because their polyanionic three-dimensional skeleton acts as electron/ion sponge, which structurally stable during redox processes...
