Ag‐Embedded Carbon Nanotube Bucky Papers for Lithium Metal Full Batteries

open access: yesBatteries &Supercaps, EarlyView.
The lithiophilic 3D carbon host is fabricated with multi‐walled carbon nanotubes and silver nitrate as an Ag precursor for the Li metal anode, which provides a conductive pathway and site for high Li affinity. Owing to lowered Li nucleation overpotential and uniform Li deposition, the Li@Ag/MCBP–10 with variable cathode exhibits enhanced cycle ...

A Cellular Automation for Real‐Time Electrolyte Wetting Simulation in Multilayer Lithium‐Ion Cells: From Lab Data to Full‐Scale Formats

open access: yesBatteries &Supercaps, EarlyView.
A cellular automaton model is introduced for simulating electrolyte wetting in porous battery composites. The model offers high flexibility, near real‐time runtimes, and strong agreement with experimental data. Validated on individual and multilayer configurations, the model enables fast, accurate wetting prediction for pouch, and cylindrical cell ...

In‐Depth Analysis of the Origin of Enhanced Ionic Conductivity of Halide‐Based Solid‐State Electrolyte by Anion Site Substitution

open access: yesBatteries &Supercaps, EarlyView.
The effect of sulfur doping on Li2ZrCl6 is systematically investigated. The formation of biphasic mixtures is confirmed by neutron and X‐ray diffraction studies. The presence of dual anion doping shows improved ionic conductivity of 0.64 mS cm−1. The transition from 1D to 2D pathway (confirmed by density functional theory (DFT)) is beneficial in ...

Understanding the Temperature–Induced Decomposition of Commercial Nickel–Cobalt–Aluminum Oxide (LiNi0.8Co0.15Al0.05O2) Electrodes

open access: yesBatteries &Supercaps, EarlyView.
High‐resolution X‐ray diffraction and thermal analysis show the structural degradation of the NCA cathode from a layered structure over a spinel phase toward the rock salt structure within a temperature range from 180 to 1000 K. This study addresses the thermal degradation and structural stability of the NCA (nickel–cobalt–aluminum oxide) cathode ...

Operando Scanning SAXS/WAXS Cell Design for Multiscale Analysis of All‐Solid‐State Battery Systems

open access: yesBatteries &Supercaps, EarlyView.
A novel cell enables operando scanning small‐ and wide‐angle X‐ray scattering across an all‐solid‐state lithium‐sulfur cell. Spatially resolved structural evolution is being tracked, revealing heterogeneous cathode reactions, confined sulfur‐to‐sulfide conversion in nanopores, and an anisotropic lithiation mechanism in the lithium‐indium anode ...

3D Resolved Computational Modeling to Simulate the Electrolyte Wetting of a Lithium‐Ion Battery Cell with 18650 Format

open access: yesBatteries &Supercaps, EarlyView.
The electrolyte wetting of a lithium ion battery cylindrical cell is explored in this study with a 3D resolved continuum model that considers the exact spiral geometry found in commercial 18650 cells. The jelly roll architecture and capillary pressure are shown to be key determinants of the wetting degree and electrolyte distribution within the cell ...

Next‐Generation LiS Batteries: Impact of Nanowire‐Based Electrocatalysts

open access: yesBatteries &Supercaps, EarlyView.
The graphical abstract features the central themes of this review. It highlights the key challenges limiting the practical applications of lithium–sulfur batteries (LSBs) and discusses how nanowire (NW)‐based electrocatalysts help to address these issues.

Neutrons for rafts, rafts for neutrons

The European Physical Journal E, 2013
The determination of the structure of membrane rafts is a challenging issue in biology. The selection of membrane components both in the longitudinal and transverse directions plays a major role as it determines the creation of stable or tunable platforms that host interactions with components of the outer environment.

Neutron Production, Neutron Facilities and Neutron Instrumentation

Reviews in Mineralogy and Geochemistry, 2006
The main natural source of free neutrons is secondary radiation from cosmic radiation (creation of particles by interactions of cosmic radiation particles with atoms of the earth’s atmosphere). The main sources of neutrons generated artificially are nuclear reactors. Free neutrons have an average lifetime of about 888 seconds (e.g., Mampe et al.
