Charging Up Lithium-Ion Battery Cathodes [PDF]

open access: yesJoule, 2018
Lithium-ion battery cathode materials are layered with complexity. In this issue of Joule, Tian and coworkers probe NMC622 (LiNi0.6Mn0.2Co0.2O2) oxide interfacial and bulk behavior in a comparative study of chemical versus electrochemical (de)lithiated processed samples. Spatially resolved nickel oxidation state mapping reveals flaws in particle charge

Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

open access: yesAdvanced Functional Materials, EarlyView.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Charge transport phenomena in thin-film cathodes

open access: yesSolid State Ionics, 1992
Abstract The OCV, chemical diffusion coefficient and thermodynamic enhancement factor has been determined as a function of lithium content in MOCVD TiS 2 films. The films were deposited in a cold-wall reactor at 7.5 mbar, 207 and 250°C, and a feed gas composition of 0.25 vol% TiCl 4 and 1.4 vol% hexamethyldisilathiane.
