Nano-Micro Letters 2023年第2期15卷 182-197页

作者： Huan Liu Xiang Cai Xiaojuan Zhi Shuanlong Di Boyin Zhai Hongguan Li Shulan Wang Li Li Department of Chemistry College of ScienceNortheastern UniversityShenyang 110819LiaoningPeople’s Republic of China School of Light Industry and Chemical Engineering Dalian Polytechnic UniversityDalian 116034LiaoningPeople’s Republic of China State Key Laboratory of Rolling and Automation Northeastern UniversityShenyang 110819LiaoningPeople’s Republic of China School of Metallurgy Northeastern UniversityShenyang 110819People’s Republic of China

Developing advanced electrode materials is crucial for improving the electrochemical performances of proton ***,the anodes are primarily crystalline materials which suffer from inferior cyclic stability and high electrode ***,we propose amorphous electrode materials for proton batteries by using a general ion-exchange protocol to introduce multivalent metal cations for activating the host *** Al^(3+)as an example,theoretical and experimental analysis demonstrates electrostatic interaction between metal cations and lattice oxygen,which is the primary barrier for direct introduction of the multivalent cations,is effectively weakened through ion exchange between Al^(3+)and pre-intercalated K+.The as-prepared Al-MoOx anode therefore delivered a remarkable capacity and outstanding cycling stability that outperforms most of the state-of-the-art *** assembled full cell also achieved a high voltage of 1.37 *** work opens up new opportunities for developing high-performance electrodes of proton batteries by introducing amorphous materials.
