Metal Battery Anode: Rich in Electrons, Rich in Problems: A Critical Review from Industrial Perspectives

open access: yesAdvanced Science, EarlyView.
Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

Dielectric Breakdown in Solids

Proceedings of the Physical Society. Section B, 1956
It is shown that already at fairly low electronic densities (of the order 1014 cm-3) an electron exchanges energy with other electrons quicker than with lattice vibrations, mainly because collisions with the latter are nearly elastic. The notation of an electronic temperature T, which in an external field is higher than the lattice temperature, is then

Theory of Dielectric Breakdown in Metal-Loaded Dielectrics

Physical Review B, 1987
We have examined a very simple model of dielectric breakdown in random mixtures of metal and dielectric.1,2,3 We expect this analysis to be relevant for an class of materials which are composed of a random mixture of metallic particles embedded in a dielectric matrix.

Dynamics of dielectric breakdown paths

Physical Review E, 2003
We investigate the dynamics and geometry of dielectric breakdown paths of needle defects of arbitrary residual resistivity in an otherwise homogeneous medium using a time-dependent electrical-circuit model. The circuit model consists of a semi-infinite lattice of capacitors in parallel with resistors that break down to a lower (residual) resistance ...
