Fast ion conductors, sometimes referred to as superionic conductors or solid electrolytes, are solids with ionic conductivities that are comparable to those found in molten salts and aqueous solutions of strong electrolytes, i.e., 10-2-10 S cm-1. Such materials have been known of for a very long time and some typical examples of the conductivity are ...

Fast beam-ion instability. II. Effect of ion decoherence
Physical Review E, 1995The ionization of residual gas by an electron beam in an accelerator generates ions that can resonantly couple to the beam through a wave propagating in the beam-ion system. A beam-ion instability is studied for a multibunch train, taking into account the decoherence of ion oscillations due to the ion frequency spread.

Journal of Non-Crystalline Solids, 1985
Abstract General aspects of fast ion conducting glasses are first presented. Conduction processes in such glasses are discussed in terms of the “random site model”, the “weak electrolyte model” and the “conduction path model”; the applicability of the conduction path model to some systems is tested.

Publisher Summary This chapter discusses that neutron scattering techniques have been applied to study a variety of phenomena in relation to the structure and dynamics of fast ion conductors. The structural studies give descriptions of the average crystallographic order with the distribution of atoms in the unit cell presented, either in terms of ...

Fast Sodium‐Ion Conductivity in Supertetrahedral Phosphidosilicates
Angewandte Chemie, 2018AbstractFast sodium‐ion conductors are key components of Na‐based all‐solid‐state batteries which hold promise for large‐scale storage of electrical power. We report the synthesis, crystal‐structure determination, and Na+‐ion conductivities of six new Na‐ion conductors, the phosphidosilicates Na19Si13P25, Na23Si19P33, Na23Si28P45, Na23Si37P57, LT ...

Fast Charging Lithium-Ion Batteries
SAE Technical Paper Series, 2017<div class="section abstract"><div class="htmlview paragraph">We try to understand the fast recharge capability of automotive lithium-ion batteries and its effect of fast charge on capacity degradation. We find out that 5 Ah prismatic Li-ion cells can be fully recharged in 3 minutes under a constant rate of 20C, or in 2 min (25.5C) from 0 ...

It is now several decades since the subject of fast ion conduction in crystalline materials was first seriously examined. Scientists were and still remain fascinated with the source of the anamalously high ion conductivities and technologists with the possibilities for these materials in high energy density batteries, sensors, displays, etc.

Fast ion transport in composites
Solid State Ionics, 1986Abstract Calorimetric investigations on AgI-AgBr and AgI-AI 2 O 3 composites yield large enthalpies. Results are interpreted in terms of enhanced defect interactions at interphase intrefaces. Evidence for a Lix·1/2H 2 O composition is presented.

Fast-ion-beam photoelectron spectrometer
Review of Scientific Instruments, 1995A high-collection-efficiency fast-ion-beam photoelectron spectrometer is described. In a straight time-of-flight mode, the spectrometer collects ∼1% of the photoelectrons and achieves an energy resolution of ΔE/E of ∼5%. For coincidence experiments requiring greater collection efficiency, a paraboloidal electrostatic mirror is used. The mirror collects

Fast ion beams reveal structures of molecular ions
Physics Today, 1979Of the many ionic species that normally emerge from the ion source of an electrostatic accelerator, it has traditionally been only the monatomic ions that are considered to provide “useful” beams. The remaining beams of molecular ions (H2+, H3+, HeH+, OH+, etc.), which frequently constitute as much as 90% of the total ion-beam current, are seldom used ...
