Fish‐scale‐like nano‐porous membrane based on zeolite nanosheets for long stable zinc‐based flow battery

et al. 2022

Zinc-based flow batteries receive widespread attention due to their advantages of low cost and high energy density. However, zinc dendrites are easy to appear during the charge process, pierce the membrane and thus destroy the battery, which seriously restrict its further development. In this article, MFI-type zeolite nanosheets (ns-MFIs) with high mechanical strength and hydrophobicity are in situ introduced to porous polymer membranes, which spontaneously form turnup fish-scale-like structure through the one-step phase inversion/surface segregation process. This special structure well disperses mechanical energy to provide effective protection characteristics to resist the penetration of zinc dendrites, and meanwhile promotes the uniform zinc depositions on the electrode by alleviating the water migration and accelerating zincate ion diffusion, so as to prolong the cycle life of the battery for more than 600 cycles, which is 4 times and 2.5 times longer than the commercial Nafion 212 and pristine porous polymer membrane, respectively. Moreover, the subnano size pores and high-aspect-ratio of ns-MFIs afford membranes extra ion sieving ability and transport area for the charging-balancing ions OH À to ensure superior battery performance, delivering an average coulombic efficiency (CE) of ~98.5%, voltage efficiency (VE) of ~83.2%, and energy efficiency (EE) of ~81.9% at 80 mA/cm 2 .

Acceleration of thermal decomposition of molten nitrates by Cr in steel and promotion of this effect by halogens

et al. 2022

Molten salts have been widely studied as the most common heat storage medium for concentrated solar power (CSP) plants. However, most studies have focused on the corrosiveness of molten salts, while this study innovatively reveals the role of stainless steel in promoting the decomposition of molten salts and the mechanism by which the halogen ions accelerate this process. Considering commercial Solar Salt as an example, the thermal stability, composition, and thermophysical properties of Solar Salt adding Cl−, Br−, and I− after contacting different stainless steel were analyzed. The results showed that Cr was the main reason for the decomposition of the molten salt, and Cl−, Br−, and I−, all accelerated the decomposition. Meanwhile, different halogen ions promoted the decomposition of molten salts through different mechanisms: oxide layer destruction and chain oxidation.

Simultaneous design and operation optimization of renewable combined cooling heating and power systems

et al. 2020

Combined cooling, heating, and power (CCHP) systems are promising solutions for conserving energy and reducing emissions. This article proposes a new mixed-integer linear programming (MILP) model for simultaneous design and operation optimization of a renewable CCHP system, considering component nonlinear operating characteristics and performance degradation with time. A bi-objective MILP problem is solved to achieve a trade-off between total annual cost (TAC) and greenhouse gas emissions (GHGe). A case study of a commercial region is employed to demonstrate our proposed methodology. The results shows, in comparison with conventional cost minimization, our solution features a tardy increase of 12.8% in TAC and a sharp reduction of 75.5% in GHGe. Moreover, we find that ignoring performance degradation leads to an over-estimation of 2.3-13.7% in system economic performance. The proposed methodology provides an effective and flexible framework for optimal design and operational analysis of renewable CCHP systems.
