Degradation Pathways of Silicon‐Based Anodes in Lithium‐Ion Batteries
Advanced Energy Materials, EarlyView.Silicon‐based anodes undergo degradation through five primary pathways: (1) mechanical and structural deterioration of the active material, (2) loss of electrode integrity and electrical contact, (3) mechanical instability of the solid electrolyte interphase (SEI), characterized by repetitive fracture and deformation, (4) chemical instability of the ...

Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization
Advanced Energy Materials, EarlyView.Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...

Advanced Energy Materials, EarlyView.A compact, nonporous, and highly crystalline layered inorganic precursor formed by thermal evaporation inherently restricts its conversion into the halide perovskite phase during vapor‐assisted hybrid two‐step deposition. Introducing localized heterogeneous nucleation sites during vapor deposition enables deliberate modulation of the inorganic layer's ...

Thermal runaway and thermal runaway propagation in batteries: What do we talk about?
Journal of Energy Storage, 2019Abstract Investigations describing incidents with electrochemical cells, in which the cell heats up and is either destroyed or severely damaged, causing damage to the immediate environment of the cell, are frequently referred to as “thermal runaway“. However, the term is used in most papers without a clear definition of what is meant.

SIAM Journal on Applied Mathematics, 1985
Ignition of an initially cold combustible gas is studied when chemical reaction is switched on due to the passage of a piston-supported shock of sufficient strength. The time and space history of the shocked gas up to the instant of thermal runaway is described, by using a combination of asymptotic and numerics.

Thermal runaway by thermal analysis
Thermochimica Acta, 1990Abstract The effect of heating rate on thermal runaway has been investigated by thermal analysis. For the materials studied in the present work there was an increase in the ignition temperature as the heating rate was increased. At high heating rates the effect was largely determined by the thermal relaxation time.
