Abstract Energy‐efficient, safe, and reliable Li‐ion batteries (LIBs) are required for a wide range of applications. The introduction ultra‐thick graphite anodes, desired high energy densities, meets limitations in internal electrode transport properties, leading to detrimental consequences. Yet, there is lack experimental tools capable providing complete view local processes. Here, multi‐modal operando measurement approach introduced, enabling quantitative spatio‐temporal observations Li...
Hydrogel electrolyte interdigitation is introduced as an effective strategy for stable 3D zinc metal anode design, allowing fast mass transport into the tortuous framework and uniform deposition/dissolution across entire structure.
High temperature polymer electrolyte membrane fuel cells (HT-PEMFCs) are used for stationary to mobile applications and show increased tolerances impurities like CO compared their low counterpart. However, conventional HT-PEMFC membranes, based on polybenzimidazole (PBI), suffer from creeping during long-term operation thus a significant increase in surface resistance. In this study, inorganic fillers terms of silicon carbide (SiC) incorporated into the standard PBI-based Celtec®-P by...
The rapid development of X-ray micro-computed tomography (micro-CT) opens new opportunities for 3D analysis particle and grain-size characterisation, determination densities shape factors, estimation mineral associations liberation locking. Current practices in are based on 2D representations leading to systematic errors the extrapolation volumetric properties. New quantitative methods tomographic data therefore urgently required characterisation deposits, processing, tailings, rock typing,...
Lead-free piezoelectric single crystals of Fe-doped 0.95(Bi1/2Na1/2)TiO3-0.05BaTiO3 are shown to combine multiple mechanisms for high strain and an effective coefficient up 3260 pm/V. This is explained based on the analysis superstructure reflections from diffuse synchrotron x-ray scattering. It depends three factors: (1) stabilization a local tetragonal structure by (Fe'-VO∙∙)• defect dipoles, (2) reversible creation morphotropic phase boundary under field, (3) field-induced transition...
Obtaining a complete picture of local processes still poses significant challenge in battery research. Here we demonstrate an in-situ combination multimodal neutron imaging with diffraction for spatially resolved operando observations the lithiation-delithiation graphite electrode Li-ion cell. Throughout process image Li distribution based on beam attenuation. Simultaneously, observe development lithiated phases as function cycling time and thickness integral throughout its volume by...
Energy efficient, safe and reliable Li-ion batteries (LIBs) are required for a wide range of applications. Charging capabilities thick electrodes still holding their stored high-energy is most desirable characteristic in future advanced LIBs. The introduction ultra-thick graphite anode meets limitations internal electrode transport properties, leading to gradients with detrimental consequences battery cell performance lifetime. Yet, there lack experimental tools capable providing complete...

Within geological samples, understanding the 3D distribution and concentration through mineral liberation analysis is vital for characterization in resource industry energy environmental applications.While there are existing techniques available that can provide this identification 2D with SEM-based methods [1], a lack of providing analogous representations.Here, we present method using machine learning to obtain phase information from combined μ-XRF μ-CT methodology essentially propagates...
Results showed 4 prominent scattering features that are apparent in the 3D diffuse volumes, each providing information on a unique small-to medium-range structure.1. Broad around Bragg reflection coordinates indicate an atomic size effect from pseudo-random occupation of sodium and bismuth A-site perovskite structure.2. Reflections occurring half-integer planes doubling unit cell through oxygen octahedral rotations all directions, result average rhombohedral symmetry.3. Diffuse streaks...
