| 1 | Elevating kinetics of passivated Fe anodes with NH_(4)Cl regulator:Toward low-cost,long-cyclic and green cathode-free Fe-ion aqueous batteries显示文摘The environment benignity and battery cost are major concerns for grid-scale energy storage applications.The emerging dendrite-free Fe-ion aqueous batteries are promising due to the rich natural abundance,low cost and non-toxicity for Fe resources.However,serious passivation reactions on Fe anodes and poor long-term cyclability for matched cathodes still stand in the way for their practical usage.To settle above constraints,we herein use NH_(4)Cl as the electrolyte regulator to elevate the reaction kinetics of passivated Fe anodes,and also propose a special cathode-free design to prolong the cells lifetime over 1,000 cycles.The added NH_(4)Cl can erode/break inert passivation layers and strengthen the ion conductivity of electrolytes,facilitating the reversible Fe plating/stripping and Fe^(2+)shuttling.The highly puffed nano carbon foams function as current collectors and actives anchoring hosts,enabling expedite Fe^(2+)adsorption/desorption,FeII/FeIII redox conversions and FeIII deposition.The configured rocking-chair Fe-ion cells have good environmental benignity and decent energy-storage behaviors,including high reactivity/reversibility,outstanding cyclic stability and far enhanced operation longevity.Such economical,long-cyclic and green cathode-free Fe-ion batteries may hold great potential in near-future energy-storage power stations. | Shibo Chai Jianhui Zhu Jian Jiang Chang Ming Li | 2022 | Nano Research2022，15，4： | 1 |
| 2 | A Pseudopotential Lattice Boltzmann Analysis for Multicomponent Flow显示文摘This paper presents a pseudopotential lattice Boltzmann analysis to show the deficiency of previous pseudopotential models,i.e.,inconsistency between equilibrium velocity and mixture velocity.To rectify this problem,there are two strategies:decoupling relaxation time and kinematic viscosity or introducing a system mixture relaxation time.Then,we constructed two modified models:a two-relaxationtime(TRT)scheme and a triple-relaxation-time(TriRT)scheme to decouple the relaxation time and kinematic viscosity.Meanwhile,inspired by the idea of a system mixture relaxation time,we developed three mixture models under different collision schemes,viz.mix-SRT,mix-TRT,and mix-TriRT models.Afterwards,we derived the advection-diffusion equation for the multicomponent system and derived the mutual diffusivity in a binarymixture.Finally,we conducted several numerical simulations to validate the analysis on these models.The numerical results show that these models can obtain smaller spurious currents than previous models and have a wider range for the accessible viscosity ratio with fourth-order isotropy.Compared to previous models,presentmodels avoid complex matrix operations and only fourth-order isotropy is required.The increased simplicity and higher computational efficiency of these models make them easy to apply to engineering and industrial applications. | Yong Zhao Gerald G.Pereira Shibo Kuang Zhenhua Chai Baochang Shi | 2022 | Communications in Computational Physics2022，32，9： | 0 |
