Capacity loss of non-aqueous Li-Air battery due to insoluble product formation: Approximate solution and experimental validation [PDF]

, 2019
In this paper, we present a study of Lithium (Li)-air battery capacity by accounting for the voltage loss associated with the electrode passivation and transport resistance caused by insoluble product formation.

How Voltage Drops are Manifested by Lithium Ion Configurations at Interfaces and in Thin Films on Battery Electrodes

, 2015
Battery electrode surfaces are generally coated with electronically insulating solid films of thickness 1-50 nm. Both electrons and Li+ can move at the electrode-surface film interface in response to the voltage, which adds complexity to the "electric ...

Sulfur Reduction Pathways and Through-thickness Distribution in Positive Composite Electrodes of All-solid-state Li–S Batteries: Elucidation of Two-stage Discharge Plateaus

Electrochemistry
Sulfur positive electrodes in liquid-type lithium–sulfur (Li–S) batteries exhibit two discharge plateaus at approximately 2.4 and 2.1 V (vs. Li). However, conventional sulfur composite electrodes in all-solid-state Li–S batteries typically do not display

Unique compounds functionalized with three-membered cyclic structures

Green Chemical Engineering
Three-membered cyclic compounds are a fascinating class of compounds: they have the maximum torsional and angular strain (sp3 hybridization but bond angles deviate from 109°28’), and possess unique physical and chemical properties.

A composite cathode with a three-dimensional ion/electron-conducting structure for all-solid-state lithium–sulfur batteries

Communications Materials
All-solid-state lithium–sulfur batteries exhibit high energy densities, operate safely, and suppress polysulfide shuttling. However, their electrochemical performance is restricted by the insulating nature of sulfur and Li2S, and by severe cathode ...
