与插层型锂离子电池(LIB)相比,转换型锂硫(Li-S)电池因为其高理论能量密度(2600 Wh kg-1)而受到越来越多的关注。但是,多硫化物穿梭效应、缓慢的反应动力学和锂金属枝晶生长等问题阻碍了锂硫电池的进一步应用。硫正极的多步转化反应涉及电极/电解质之间一系列Li+的交换,这些反应也亟需克服脱溶剂和电荷载体扩散的能量势垒,这导致了缓慢的转化动力学以及多硫化物中间体的积累。
The leaves of trees and plants have been called the Earth’s lungs because they take in carbon dioxide and give out oxygen. But beneath the soil’s surface, the roots of those plants are doing their bit...
The key to electrochemical energy storage systems such as Li/Na-ion batteries is materials. The traditional method for exploring new materials is trial-and-error, which often takes a dozen years durin...
Batteries made from an electrically conductive mixture the consistency of molasses could help solve a critical piece of the decarbonization puzzle. An interdisciplinary team from MIT has found that an...
Cornell bioengineer Buz Barstow, Ph.D. ’09, is trying to solve a big problem: How to build a low-cost, environmentally friendly and large-scale system for storing and retrieving energy from renewable ...
2020年,国际著名期刊《Journal of Hydrology》刊发了中国地质大学资源学院“油气藏渗流力学与数值模拟”团队特任教授王磊及地空学院蔡建超教授合作的最新研究成果——“Unsteady flow to a partially penetrating pumping well with wellbore storage in a dual-permeability confined a...
近日,上海交通大学制冷与低温工程研究所王如竹教授领衔的能源-空气-水(ITEWA)创新团队,在Energy Storage Materials上发表了题目为“Sorption Thermal Energy Storage: Concept, Process, Applications and Perspectives”的综述论文,总结了吸附储热技术在材料、工作循环、系统设计和系统运新特性等方面的研...
A team of National Science Foundation-funded researchers has made substantial progress in creating a new type of data storage system.As the data universe continues to expand, much work is being done t...
2020年1月22日,王如竹教授领导的能源-空气-水(ITEWA)创新团队,在Energy Storage Materials上发表了题目为“Air Humidity Assisted Sorption Thermal Battery Governed by Reaction Wave Model”的研究论文,发现吸附反应床内的反应波现象并提出反应波模型,阐释了吸附热池实现稳定输出的机理,以及新型...
The sea is Earth's most formidable carbon dioxide storage machine, but mysteries abound about the interlocking processes and the myriad organisms involved.Now, thanks to NSF-funded research published ...
You might expect that plants hoping to thrive in California's boom-or-bust rain cycle would choose to set down roots in a place that can store lots of water underground to last through drought years.B...
The effects of a simple saline solution prepared using two different pH (4.4 and 8.5) on sperm motility in burbot were investigated. Results were recorded during a 96-hour chilled storage (4°C) in 24-...
The Gordon Research Seminar (GRS) on Carbon Capture, Utilization and Storage (CCUS) is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and ed...
Interfaces and interphases are at the heart of the electrochemical reactions. Manipulating interfaces and interphases so that the electrochemical reactions and processes take place in a controlled and...
The development of high energy density electrochemical energy storage is dependent upon the identification of new materials and new mechanisms. To date, the most successful electrochemical energy stor...
