Summary: In this study, a pure phase BaCo0.5Fe0.5O3-delta (BCF) was successfully prepared for the first time using a calcination method with rapid cooling. The BCF material was evaluated as a cathode for proton-conducting solid oxide fuel cells (H-SOFCs), and it achieved a fuel cell performance of 2012 mW.cm(-2) at 700 degrees C, which is double that of a similar cell using the classical Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) cathode. The improved performance of the BCF cathode was attributed to the lower energy barriers in the oxygen reduction reaction (ORR) compared to the BSCF cathode. The fuel cell using the BCF cathode also exhibited excellent long-term stability, working stably for nearly 900 hours without noticeable degradation. This research suggests that BCF is a promising cathode material for H-SOFCs.

Summary: The objective of this study is to optimize the performance of a graphitized carbon xerogel doped with graphene oxide (GXGO) as cathode for sodium dual-ion batteries. The intercalation of PF6- anions from various NaPF6 salt-based electrolytes in a GXGO-based cathode is investigated by considering the influence of the upper cut-off voltage (UCOV) and of the electrolyte on the electrochemical parameters. The best results were attained in an electrolyte with a 2.0 M NaPF6 concentration in EC : EMC carbonate solvent mixture with added FEC, at a UCOV of 5.0 V. GXGO cathode provides a discharge capacity of 47 mAh g(-1) after 2500 cycles with a coulombic efficiency of 97 %. Moreover, it shows great cycling stability and capacity retention of essentially 100 % after the initial cycles.

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.
