锂空电池最新综述—麻省理工的杨绍红组的力作发表在EES上

最新一期的EES刊发了题为Lithium-Oxygen Batteries Bridging Mechanistic Understanding and Battery Performance 的综述,详细的介绍了锂空气电池的最新研究进展,特别讨论了non-carbonate electrolytes 基于充放电的 Li-O2氧化还原反应非碳酸盐电极质化学、基于放电的氧还原反应产物的表征、常用于氧电极的电解质和碳的化学不稳定性等方面,并对相关的电化学领域性质做了介绍。 Rechargeable energy storage systems with high energy density and round-trip efficiency are urgently needed to capture and deliver renewable energy for applications such as electric transportation. Lithium-air / lithium-oxygen (Li-O2) batteries have received extraordinary research attention recently owing to their potential to provide positive electrode gravimetric energies considerably higher (~3-5x) than Li-ion positive electrodes, although the packaged device energy density advantage will be lower (~2x). In light of the major technological challenges of Li-O2 batteries, we discuss current understanding developed in non-carbonate electrolytes of Li-O2 redox chemistry upon discharge and charge, oxygen reduction reaction product characteristics upon discharge, and the chemical instability of electrolytes and carbon commonly used in the oxygen electrode. We show that the kinetics of oxygen reduction reaction are influenced by catalysts at small discharge capacities (Li2O2 thickness less than ~ 1 nm), but not at large Li2O2 thicknesses, yielding insights into the governing processes during discharge. In addition, we discuss the characteristics of discharge products (mainly Li2O2) including morphological, electronic and surface features and parasitic reactivity with carbon. On charge, we examine the reaction mechanism of the oxygen evolution reaction from Li2O2 and the influence of catalysts on bulk Li2O2 decomposition. These analyses provide insights into major discrepancies regarding Li-O2 charge kinetics and the role of catalyst. In light of these findings, we highlight open questions and challenges in the Li-O2 field relevant to developing practical, reversible batteries that achieve the anticipated energy density advantage with a long cycle life. 1.jpg 2.jpg [ 来自科研家族 锂电池世界 ] [ Last edited by zlin on 2013-8-12 at 12:28 ] |
