The Effect of Mud Cracking on the Performance of Thick Li‐Ion Electrodes

Will J. Dawson, Andrew R. T. Morrison, Francesco Iacoviello, Adam M. Boyce et autres

Abstract Electrode‐level fracture, or mud cracking, occurs during the drying process of Li‐ion electrodes and is known to be particularly prevalent in thick electrodes. Whilst these cracks are generally viewed as an obstruction to the production of thicker, more energy dense electrodes, …

Backside Power Distribution for Nanosheet Technologies Beyond 2nm

Ruilong Xie, Wonhyuk Hong, Chen Zhang, Joongku Lee et autres

This paper examines various approaches for integrating backside power distribution network (BSPDN) with nanosheet transistor technologies. Deep Trench Via (DTV) based BSPDN schemes, except for Shifted Frontside Via Backside Power rail (SFVBP), do not offer cell level scaling benefits, but via resistance …

Population inversion mechanism of optically pumped metastable rare gas based on laser-induced preionization

Shu Hu, Juntao Li, Baodong Gai, Peng‐Yuan Wang et autres

A 532 nm laser was used to induce ionization of Ar–He mixture, and metastable 4s [3/2] 2 level Ar atoms were prepared. The interaction mechanism between laser, Ar atoms, He atoms and free electrons in laser-induced plasma (LIP) was revealed. Through time-resolved …

Structure‐guided Capacitance Relationships in Oxidized Graphene Porous Materials Based Supercapacitors

Srinivas Gadipelli, Hanieh Akbari, Juntao Li, Christopher A. Howard et autres

Supercapacitors formed from porous carbon and graphene‐oxide (GO) materials are usually dominated by either electric double‐layer capacitance, pseudo‐capacitance, or both. Due to these combined features, reduced GO materials have been shown to offer superior capacitance over typical nanoporous carbon materials; however, there …

Synthesis and Optimization of Zeolitic Imidazolate Frameworks for the Oxygen Evolution Reaction

Juntao Li, Srinivas Gadipelli

Abstract Metal–organic frameworks/zeolitic imidazolate frameworks (MOFs/ZIFs) and their post‐synthesis modified nanostructures, such as oxides, hydroxides, and carbons have generated significant interest for electrocatalytic reactions. In this work, a high and durable oxygen evolution reaction (OER) performance directly from bimetallic Zn100−xCox‐ZIF samples is …

High-Performance Zinc–Air Batteries with Scalable Metal–Organic Frameworks and Platinum Carbon Black Bifunctional Catalysts

Juntao Li, Zhu Meng, Dan J. L. Brett, Paul Robert Shearing et autres

Metal–organic framework (MOF)-related derivatives have generated significant interest in numerous energy conversion and storage applications, such as adsorption, catalysis, and batteries. However, such materials’ real-world applicability is hindered because of scalability and reproducibility issues as they are produced by multistep postsynthesis modification …
