Abstract The abundance of active material precursors for a polysulfide-permanganate flow battery makes it a compelling chemistry for large-scale, and potentially long-duration (>10 hours), grid electricity storage. Precipitation, arising from either reactant crossover or electrolyte side reactions, decrease cell efficiencies during charge/discharge cycling. Regardless of the abundance and low cost of active materials, a system without high cyclability cannot meet grid electricity storage economic targets for applications that cycle regularly. Precipitated species can be removed, and reactor performance restored, by using an electrolyte takeover process, or ETP. Two ETP methods are investigated. One ETP uses the negative electrolyte, an alkaline polysulfide (pS) solution, as takeover solution, and another uses dilute acidic peroxide (DAP) as the takeover solution. Both ETPs maintain functional cell operation within an acceptable performance range over >1000 hours and >200 cycles, a duration over which cells that do not undergo ETPs clog and fail. The DAP ETP proves especially effective and limits irrecoverable voltage efficiency fade below 0.02%/cycle. These ETPs, either individually, or in combination, can enable the requisite cyclability for practical polysulfide-permanganate flow battery systems.

Abstract A neutral aqueous tin-based flow battery is proposed by employing Sn2+/Sn as active materials for the negative side, [Fe(CN)6]3-/ Fe(CN)6]4- as active materials for the positive side, and potassium chloride as the supporting electrolyte, and its overall performances and cost for capacity unit are investigated. Cyclic voltammetry is performed and shows that the Sn2+/Sn has outstanding electrochemical behavior. The charging-discharging tests are conducted with the optimized electrolyte composition of 0.2 M [Fe(CN)6]3- and 3 M KCl. It is shown that the flow cell can reach a high energy efficiency of 80% at 10 mA cm-2 and be stably operated at 40 mA cm-2. The 120-cycling test shows that the flow cell can be of superior cycling performances, benefitting from the dendrite-free property of tin. Finally, cost analysis further confirms its competitiveness in price, offering a promising future for commercial application. This work not only forms a promising energy storage device with dendrite-free and low-cost benefits, but also provide a deep insight into its overall behavior, which is highly beneficial to the full understanding and further advancement of the proposed neutral tin-iron flow battery.

Abstract Redox-flow batteries (RFBs) enable large-scale energy storage at low cost due to the independent scaling of device power and energy, thereby unlocking energy arbitrage opportunities and providing a pathway to grid stability and resiliency. Herein we demonstrate an “electrode-decoupled” redox-flow battery (ED-RFB) with titanium and cerium elemental actives that has a clear pathway to achieve a levelized cost of storage (LCOS) of ca $0.025/kWh-cycle. A key enabling technology is our highly perm-selective modified poly(ether ketone)-based anion exchange membrane (AEM) that ensures long term separation of Ti and Ce species and enables capacity-fade-free cycling over 1300 hours of operation. Further, our Ti-Ce ED-RFB exhibits negligible capacity fade when the actives are charged to 90% state of charge (SOC), stored for close to 100-hours and then discharged, rendering it viable for long duration (load-following) grid-scale energy storage applications. Herein we introduce the Ti-Ce ED-RFB as a novel, low-cost long duration energy storage (LDES) system.

With the rapid development and wide application of Li-ion batteries, cathode materials containing value metals Co, Ni and Mn are blended by several kind of metal oxide presently for pursuing high safe stability and low cost. The composition of spent Li-ion batteries has become complicated and optimum leaching condition varied. In this paper, leaching process for the mixture of pure LiCoO2and Li (Ni1/3Co1/3Mn1/3)O2was studied. With an increase in component of LiCoO2in mixed materials, the optimum leaching condition varied as: temperature from 60°C to 90°C, H2O2addition amount from 0.54 to 0.75ml/g and liquid-solid ratio from 10 to 20. According to this result, a real mixed spent batteries materials was recovered by being leached in 2M H2SO4at temperature of 90°C, liquid-solid ratio 20 and 0.6ml/g H2O2added. The leaching efficiencies of Co, Ni, Mn, Li were 96.88%, 93.71%, 92.12%, 99.43% respectively. Cu, Al and Fe in solution were removed by precipitation and solvent extraction. Finally, Ni, Co, Mn were extracted by D2EHPA for separating with Na+and other impurities, which is used as a raw materials for preparation of cathode active materials in batteries.

The use of autonomous vehicles is growing in all industries. However, there are no open-source autonomous surface vehicles available in the marine industry. This paper details the design decisions made, construction methods used, and testing performed on a low-cost, open-source vessel. The vessel was designed to cross the Atlantic Ocean as a means of proving its ability to survive the harsh marine environment. A trimaran hull form and free rotating wing sail were used because the combination provided good righting characteristics, durability and low power consumption. The vessel has been shown to navigate autonomously. Total costs were less than $4000 dollars, excluding labor. Vessels of this type could be used for long duration missions recording data in the open ocean at extremely low cost.
