Summary: In-situ neutron diffraction was used to reveal deformation damage during tension and compression for a high manganese steel. The lattice strains along transverse and loading directions showed indications of damage during tensile and compressive stress, respectively. The distribution of damaged grains was similar to grains with large Taylor factors.

Summary: This article surveys several neutron imaging and diffraction methods for non-destructive testing and evaluation of intact, commercial lithium-ion batteries. The results show that these methods can detect battery degradation, layering, and particle scattering. In practice, the size and shape of the battery have an impact on the applicability of these methods.

Summary: In this study, the presence of short-range order (SRO) in a 1 M lithium hexafluorophosphate (LiPF6) electrolyte solution was revealed using liquid-phase transmission electron microscopy (TEM), cryo-TEM operated at -30 degrees C, four-dimensional scanning TEM, and data analysis based on deep learning. Molecular dynamics simulations suggest that the SRO originates from local structural order induced by high LiPF6 salt concentration.

Summary: In situ, spatially-resolved synchrotron X-ray diffraction was used to investigate the electric field-induced phase transformation of nonergodic relaxor 0.93Na(1/2)Bi(1/2)TiO(3)-0.07BaTiO(3) ceramics. The study found that the copper electrode side coated by aerosol deposition exhibited more significant lattice strain and domain texture compared to the platinum side deposited by sputter deposition.

Summary: Wet-chemical deposition of metal-halide perovskites shows great potential for electronic applications, particularly in solar cells. However, the distribution of light-induced excess charges over the polycrystalline material remains unclear. Using scanning microwave microscopy (sMIM), the local conductive properties of MAPbI3 and CsFAPbI3 were examined, revealing even distribution of excess charges over the grains in CsFAPbI3 but with local perturbations in carrier concentration due to defect-rich areas. This variation in carrier concentration under illumination affects the local Fermi level splitting in solar cells, highlighting the importance of suppressing it to minimize voltage deficit.

Summary: We propose and demonstrate a novel concept of thermal batteries, called barocaloric thermal batteries, which are based on the large inverse barocaloric effect of ammonium thiocyanate (NH4SCN). The thermal charging is initiated by pressurization and the discharging releases 43 J g-1 of energy, which is 11 times more than the input mechanical energy. The pressure-restrained heat-carrying phase ensures stable long-duration storage. These barocaloric thermal batteries, reinforced by their solid microscopic mechanism, are expected to significantly advance the utilization of waste heat.

Summary: Prussian blue analogs (PBAs) are promising cathode materials for sodium-ion batteries due to their low cost, comparable energy density and long cycle life. However, the crystal water in PBAs can have significant side effects on battery performance. Researchers have developed a heat-treatment method to remove water from PBAs, improving their high temperature storage performance.

Summary: The planar electrolyte and cell design can facilitate mass production of high-temperature Na-NiCl2 batteries, but challenges like molten phase management need to be addressed. This study presents planar cells with cost-efficient nickel/iron electrodes, achieving a substantially enhanced areal capacity of 150 mAh cm(-2). These cells operate at 300℃ with low resistance, delivering a specific discharge energy of 300 Wh kg(-1) at high discharge current densities. The integration of planar Na-NiCl2 cells with commercially relevant combination of areal capacity, cycling rate, and energy efficiency is demonstrated for the first time, and the contribution of secondary molten NaAlCl4 electrolyte to cell capacity during cycling is identified.

Summary: The NiS2/NiSe2 heteroboxes as anodes for SIBs exhibit advantages of exposing more active sites at phase boundaries, accelerating sodium storage kinetics, and maintaining ultralong reversible capacity and good rate capability. This rational construction of phase boundary with unique structure provides guidance for the development of advanced SIBs anode materials.

Summary: It is demonstrated that sodium formate (HCOONa), a component of the solid electrolyte interphase (SEI), can be used to design high-performance artificial SEI layers, which effectively suppress sodium dendrite formation and side reactions with the electrolyte. A single molecular layer of HCOONa formed on a commercial copper current collector extends the lifespan of anode-free Cu|Na3V2(PO4)(3) battery to 400 cycles, representing the longest reported cycle lifetime in anode-free NMBs.

Summary: By doping a heavy dose of Mg via two rational strategies, new differences in the structure and electrochemical performance are observed in the Mg-doped layered cathodes. The doping of Mg in Na11/18Mg1/18[Ni1/4Mg1/9Mn11/18]O2 leads to enhanced ordering and a large supercell of the P63 group, with Mg occupying both Na and Mn sites. The different cathode compositions (NNM, NMNMM, and NMM) show distinct voltage plateaus and electrochemical reactions, highlighting the importance of ion doping for developing high-performance materials.

Summary: This study investigates the industrial filling process of large lithium-ion cells and introduces a simple model to explain the relationship between process parameters in dosing and wetting. The results show that with an optimized parameter combination, the electrolyte can cover all surfaces within 1.5 hours, leading to a 2.5-fold increase in wetting speed compared to a poor process design.

Summary: The crack susceptibility during processing greatly affects the workability of wrought alloys. The study focused on the formability and cracking behavior of the CoNi-base superalloy CoWAlloy1 during hot rolling. It was found that the precipitation of gamma ' and the absence of recrystallization led to pronounced crack propagation and limited formability below the gamma ' solvus temperature.

Summary: This study aims to identify the dominant active species in Saltwater Batteries with dual-ion electrolyte by conducting cyclic voltammetry and full cell measurements. The results show that the cathode only (de)intercalates lithium ions, while the anode can react with both sodium and lithium ions. However, lithium is found to be the dominant active species in the dual-ion battery.
