Summary: Ni based materials have been widely studied as electrocatalysts for alkaline water electrolysis. Understanding and improving the oxygen evolution reaction (OER) active NiOOH phase is crucial. In this study, we investigated the pathways and time evolution of NiOOH decomposition at open circuit potential after polarization of sputtered NiO thin films. Our results show that NiOOH phase formed under OER conditions quickly degrades to Ni(OH)2 at open circuit potential. The detection of NiOOH ex situ is possible, but only within a limited timeframe unless stabilized in a vacuum environment.

Summary: In this study, in situ Zn-doped NCM material was successfully designed by atomic layer deposition combined with annealing. Compared with ex situ Zn-doped NCM, in situ Zn-NCM exhibited better stability and reduced surface defects due to its lower migration energy barrier and more uniform distribution of heteroatoms. As a result, it showed higher reversible capacity and initial Coulombic efficiency. Therefore, in situ doping is an effective strategy to enhance the performance of lithium-ion battery cathodes.

Summary: Experimental results demonstrate the production of dodecagonal quasicrystal (DDQC) and Frank-Kasper (FK) A15 and sigma mesophases at ambient temperature using a versatile class of sugar-polyolefin conjugates. The synthesis of stable A15 mesophases is achieved through the use of mono- and disaccharide-polyolefin conjugates, along with vitamin E as a small molecule phase modulator. A thermotropic phase map consisting of DDQC, A15, and sigma mesophases with tunable periodicity is documented, with rapid phase transitions occurring as temperature increases in the order of: liquid-like packing (LLP) -> DDQC -> A15 -> sigma -> disorder. The observation of a rapid A15 -> sigma phase transition supports a diffusionless martensitic process involving the introduction of planar defects into the A15 lattice.

Summary: Solid oxide electrolysis cells (SOECs) are highly efficient and flexible energy conversion devices, but their long-term operation is limited by the degradation of Ni/yttria-stabilized zirconia (YSZ) fuel electrodes, which is recognized as one of the main causes for cell performance loss. This study investigates the microstructure evolution of Ni/YSZ electrodes after long-term operation in a CO/CO2 atmosphere. Results show significant loss of Ni in the active electrode and increased Ni fraction in the support layer after 1000 hours of operation at -1 A cm(-2). Ni coarsening was also observed. Similarly, Ni migration away from the electrode/electrolyte interface occurs during long-term CO2 electrolysis.

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.
