Journal of Energy chemistry 2025年第1期100卷 125-143页

作者： Md Al Raihan c.adam Dyker Department of chemistry University of New Brunswick

As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct c.asses of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance c.aracteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.

1974至1986年期间,苏联煤炭工业部的煤矿约有8％的外因火灾是由矿井设备的故障造成的,而这些故障是由矿井设备部件中摩擦零件的表面摩擦发热引起的。例如,在以苏共第二十五次代表大会命名的矿井(属马卡耶夫煤炭公司)中СП—63М型输送机机头由于结构不符合规定,钢环卡在机头架固定侧板和驱动轴上右边旋转链轮间而产生摩擦引起发热,温度高达310℃。
