1Ultrathin Al2O3-coated reduced graphene oxide membrane for stable lithium metal anode显示文摘Lithium(Li) metal has been considered as the most attractive anode materials for Li-ion batteries(LIBs)due to its high theoretic specific capacity. The formation of unstable solid electrolyte interphase(SEI) and dendritic Li on the metal anode, however, hindered its practical application. Herein, to address the issues, a Li-free electrode with ultrathin Al_2O_3 coated on reduced graphene oxide(rGO) membrane that covers a Cu foil current collector was developed. The composite electrode exhibits excellent interfacial protection of lithium metal deposited between Cu foil and rGO electrochemically. Firstly, it affords good Li^+ permeability from the electrolyte. Secondly, the ultrathin Al_2O_3 has sufficient mechanical strength to inhibit the penetration of Li dendrite. Li metal was observed uniformly deposited between rGO membrane and Cu collector, and stable cycle performance of Li plating/stripping with Coulombic efficiency of ~91.75% at the 100 th cycle is achieved in organic carbonate electrolyte without any additives.Fan Zhang Fei Shen ZhaoYang Fan Xin Ji Bin Zhao ZhouTing Sun YingYing Xuan XiaoGang Han 2018Rare Metals2018,37,6:11
22020 roadmap on two-dimensional materials for energy storage and conversion显示文摘Energy storage and conversion have attained significant intere st owing to its important applications that reduce CO2 emission through employing green energy.Some promising technologies are included metalair batteries,metal-sulfur batteries,metal-ion batteries,electrochemical capacitors,etc.Here,metal elements are involved with lithium,sodium,and magnesium.For these devices,electrode materials are of importance to obtain high performance.Two-dimensional(2 D) materials are a large kind of layered structured materials with promising future as energy storage materials,which include graphene,black phosporu s,MXenes,covalent organic frameworks(COFs),2 D oxides,2 D chalcogenides,and others.Great progress has been achieved to go ahead for 2 D materials in energy storage and conversion.More researchers will join in this research field.Under the background,it has motivated us to contribute with a roadmap on ’two-dimensional materials for energy storage and conversion.Baolin Xu Shihan Qi Mengmeng Jin Xiaoyi Cai Linfei Lai Zhouting Sun Xiaogang Han Zifeng Lin Hui Shao Peng Peng Zhonghua Xiang Johan E.ten Elshof Rou Tan Chen Liu Zhaoxi Zhang Xiaochuan Duan Jianmin Ma 2019Chinese Chemical Letters2019,30,12:2
