报告摘要:Rechargeable lithium ion batteries (LIBs), as one of the most important electrochemical energy storage (EES) devices, currently provide the dominant power source for a range of devices including portable electronic devices and electric vehicles due to their high energy and power densities. The interest in exploring new electrode materials for LIBs has been drastically increasing due to the surging demands for clean energy. However, the challenging issues essential to the development of electrode materials are their low lithium capacity, poor rate ability and low cycling stability, strongly limiting their practical applications. Recent remarkable advances in material sciences and nanotechnology enable rational design of heterostructured nanomaterials with optimized composition and fine nanostructure, providing new opportunities for enhancing electrochemical performance. Herein we propose the Nanoscale Engineering of Transition–Metal Chalcogenides/Hydroxides for Boosting Electrochemical Energy Storage. This talk provides some successful examples in designing new electrode materials for boosting EES. It puts special emphasis on the design and engineering of novel heterostructured electrode materials with reduced size, large surfaces area, excellent electrical conductivity, structural stability, fast electron and ion transport, which necessarily lead to enhanced EES performance in terms of high capacity, long cycling lifespan, and high rate durability.

个人简介:Hongmei Luo earned her Ph.D in Chemical Engineering from Tulane University, USA in 2006. Dr. Luo was a postdoctoral research associate in Los Alamos National Laboratory during 2006-2009 and she joined Chemical and Materials Engineering Department at New Mexico State University (NMSU) in the fall of 2009. She was early promoted to Associate Professor with tenure in 2014. She is principal investigator of the Thin Films and Nanomaterials Laboratory at NMSU and she serves as Graduate Student Admission Director in the department. Dr. Luo’s group research focuses on epitaxial thin films for magnetic, superconducting, and battery applications, and nanostructured materials for photocatalyst, electrocatalyst, lithium-ion batteries, supercapacitors, and solar cells applications.
