Fire-Safe Hierarchical Solid Polymer Electrolytes Enabled by Dual-Functional Microcapsules for Lithium Metal Batteries. [PDF]

Adv Sci (Weinh)
Dual‐functional fire‐safe microcapsules are integrated into hierarchical solid polymer electrolytes to provide sequential protection against thermal abuse. The ammonium hydrogen phytate‐modified shell forms a protective char barrier, while the thermally triggered release of perfluoro(2‐methyl‐3‐pentanone) actively suppresses combustion, enabling safer ...

Analytical model for fast-shock ignition

AIP Advances, 2014
A model and its improvements are introduced for a recently proposed approach to inertial confinement fusion, called fast-shock ignition (FSI). The analysis is based upon the gain models of fast ignition, shock ignition and considerations for the fast ...

Diagnosis of Weibel instability evolution in the rear surface density scale lengths of laser solid interactions via proton acceleration

New Journal of Physics, 2017
It is shown for the first time that the spatial and temporal distribution of laser accelerated protons can be used as a diagnostic of Weibel instability presence and evolution in the rear surface scale lengths of a solid density target.

Cone-guided fast ignition with no imposed magnetic fields

EPJ Web of Conferences, 2013
Simulations are presented of ignition-scale fast ignition targets with the integrated Zuma-Hydra PIC-hydrodynamic capability. We consider a spherical DT fuel assembly with a carbon cone, and an artificially-collimated fast electron source.

Optimum design of imploded core plasma for effective fast ignition at GXII

EPJ Web of Conferences, 2013
In the implosion phase of the fast ignition scheme, most critical issues are breakup of the cone tip and the formation of high ρ-R core plasma to improve its heating efficiency.

Progress and prospects for an IFE relevant FI point design

EPJ Web of Conferences, 2013
The physics issues involved in scaling from sub-ignition to high gain fast ignition are discussed. Successful point designs must collimate the electrons and minimise the standoff distance to avoid multi-megajoule ignition energies.

Kinetic model for energy deposition in fast ignition

EPJ Web of Conferences, 2013
A kinetic model describing the energy deposition of fast electrons is established by considering both binary collisions and contributions due to collective process.

Fast ignition by quasimonoenergetic ion beams

EPJ Web of Conferences, 2013
The potential of quasimonoenergetic ion beams for fast ignition (FI) of fusion targets is investigated. Lithium, carbon, aluminium and vanadium ions have been considered here to determine the optimal kinetic energy for each ion type.
