Summary: In this study, Fe-doped (NH4)2V12O27·xH2O was synthesized using solvothermal method which greatly enhanced material's electrochemical performance. The resulting product showed remarkably high capacity of 165 mA h g-1 at 50 mA g-1 and ultrahigh stability with 74.2% retention over 1000 cycles at 1 A g-1. This improvement is attributed to increased intrinsic conductivity from Fe doping which promotes absorption and release kinetics of Zn2+ and prevents gradual dissolution of V-O layer.

Summary: This study investigates the effects of temperature on the performance of stack-scale vanadium redox flow batteries (VRFBs). It is found that temperature has a greater impact on the discharge capacity than on the energy efficiency. The enhancement effect of temperature on energy efficiency decreases with increasing flow rate, while it increases with the operating current density. An optimum operating condition is identified at a critical flow rate (2.88 ml min(-1) cm(-2)) and 40 degrees C for high system efficiency.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
