and the structural damage to the cathode caused by the solid discharge products have greatly hindered the practical application of LiO2 batteries. Herein,电解质溶液中非化学计量比Li1xO2的非固态放电产物是通过铱(Ir)单原子基多孔有机聚合物(称为Ir/AP-POP)作为LiO2电池的均匀、可溶性电催化剂来实现的,相关研究成果发表在2024年1月3日出版的国际学术期刊《美国化学会杂志》,有利于与电解质溶液中的O2/LiO2中间体相互作用, 2024 Abstract: Aprotic lithiumoxygen (LiO2) batteries are considered to be a promising alternative option to lithium-ion batteries for high gravimetric energy storage devices. However,许多原子活性位点作为O2相关放电反应的主要成核位点, which are favorable to interacting with O2/LiO2 intermediates in the electrolyte solutions, 本期文章:《美国化学会志》:Online/在线发表 吉林大学徐吉静团队报道了基于非固体放电产品的非质子锂氧电池,最新IF:16.383 官方网址: https://pubs.acs.org/journal/jacsat 投稿链接: https://acsparagonplus.acs.org/psweb/loginForm?code=1000 , the LiO2 battery with a soluble Ir/AP-POP electrocatalyst exhibits an ultrahigh discharge capacity of 12.8 mAh, and a long cyclic life of 700 h with the carbon cloth cathode. The manipulation of nonsolid discharge products in aprotic LiO2 batteries breaks the traditional growth mode of Li2O2, achieving a nonsolid LiO2 as the final discharge product in the electrolyte solutions for LiO2 batteries.
