TL;DR: In this paper, an internal short circuiting device was used for controlled, on-demand, initiation of thermal runaway in lithium-ion batteries, allowing analysis of the nucleation and propagation of failure within 18 650 cells through the use of high-speed X-ray imaging at 2000 frames per second.

TL;DR: For the first time, the mechanisms that lead to the most catastrophic type of cell failure, rupture, and explosion are identified and elucidated in detail and are expected to guide the development of safer commercial cell designs.

TL;DR: This work produces boron nitride with high and tunable surface area and micro/mesoporosity via a facile template-free method using multiple readily available N-containing precursors with different thermal decomposition patterns, providing a scalable route to porous borons nitride production and fundamental insights into the material's formation.

TL;DR: In this paper, a novel approach is used, which combines characterisation of hot-pressed membrane electrode assemblies using X-ray computed tomography, thermogravimetric analysis, differential scanning calorimetry and atomic force microscopy, with electrochemical performance measurements from polarisation curves and high-frequency impedance spectroscopy.

TL;DR: In this paper, an approach is used which combines ex-situ characterisation of two anode gas diffusion/microporous layers (GDL-A and GDL-B) with X-ray computed tomography (CT) and in-operando analysis using neutron imaging of operating fuel cells.
