Origin of additional capacities in metal oxide lithium-ion battery electrodes

TL;DR: High-resolution multinuclear/multidimensional solid-state NMR techniques are used with in situ synchrotron-based techniques to study the prototype conversion material RuO2, demonstrating a protocol for studying the structure and spatial proximities of nanostructures formed in this system, including the amorphous solid electrolyte interphase that grows on battery electrodes.
Journal ArticleDOI

Conversion Reaction Mechanisms in Lithium Ion Batteries: Study of the Binary Metal Fluoride Electrodes

TL;DR: These results offer the first experimental evidence explaining the origins of the high lithium reversibility in FeF(2), and suggest that the massive interface formed between nanoscale solid phases provides a pathway for ionic transport during the conversion process.
Journal ArticleDOI

Comprehensive Study of the CuF2 Conversion Reaction Mechanism in a Lithium Ion Battery

TL;DR: In this paper, the reaction mechanisms that occur in the first and subsequent cycles and the reasons for the poor charge performance of CuF2 are studied via a variety of characterization methods, including in situ pair distribution function analysis.
Journal ArticleDOI

Multiple Redox Modes in the Reversible Lithiation of High-Capacity, Peierls-Distorted Vanadium Sulfide

TL;DR: V NMR shows that the material, despite having V formally in the d(1) configuration, is diamagnetic, suggesting potential dimerization through metal-metal bonding associated with a Peierls distortion of the linear chains, supported by density functional calculations and consistent with the observed alternation in V-V distances.
Journal ArticleDOI

Flash Infrared Annealing for Antisolvent-Free Highly Efficient Perovskite Solar Cells

TL;DR: In this article, an antisolvent-free method that can be used to prepare methylammonium lead iodide (MAPbI3) PSCs with stabilized power conversion efficiencies up to 18.3% is presented.
