A strong Lewis acid imparts high ionic conductivity and interfacial stability to polymer composite electrolytes towards all-solid-state Li-metal batteries
Science China Materials - Tập 65 - Trang 2179-2188 - 2022
Litong Wang, Yunlei Zhong, Zhaorui Wen, Chaowei Li, Jingxin Zhao, Mingzheng Ge, Pengfei Zhou, Yanyan Zhang, Yuxin Tang, Guo Hong
The development of high-performance solid polymer electrolytes is crucial for producing all-solid-state lithium metal batteries with high safety and high energy density. However, the low ionic conductivity of solid polymer electrolytes and their unstable electrolyte/electrode interfaces have hindered their widespread utilization. To address these critical challenges, a strong Lewis acid (aluminum ...... hiện toàn bộ
Reduced-sized monolayer carbon nitride nanosheets for highly improved photoresponse for cell imaging and photocatalysis
Science China Materials - Tập 60 - Trang 109-118 - 2016
Qinghua Liang, Zhi Li, Yu Bai, Zheng-Hong Huang, Feiyu Kang, Quan-Hong Yang
Two-dimensional graphitic carbon nitride (g-C3N4) nanosheets (GCNNs) have been considered as an attractive metal-free semiconductor because of their superior catalytic, optical, and electronic properties. However, it is still challenging to prepare monolayer GCNNs with a reduced lateral size in nanoscale. Herein, a highly efficient ultrasonic technique was used to prepare nanosized monolayer graph...... hiện toàn bộ
Improving heat resistance of Al–Cu–Li alloy with the addition of Sc and Si
Science China Materials - Tập 66 - Trang 4285-4294 - 2023
Hao Xue, Jiaming Li, Zhiqi Wang, Junyuan Bai, Zhihao Zhao, Gaowu Qin
Al–Cu–Li alloys are important third-generation aluminum–lithium alloys in the aerospace field; however, they suffer from a service temperature below 100°C. In this work, we propose a new strategy for improving the heat resistance of Al–Cu–Li alloys at 200–300°C by promoting the nucleation of θ′ precipitates after dissolving T1 precipitates during thermal exposure with the minor addition of Sc and ...... hiện toàn bộ
Oxygen vacancies-rich cobalt-doped NiMoO4 nanosheets for high energy density and stable aqueous Ni-Zn battery

Yuenian Shen, Ke Zhang, Fang Yang, Zhihao Li, Zhe Cui, Rujia Zou, Qian Liu, Junqing Hu, Kaibing Xu
The enhancement of energy density and cycling stability is in urgent need for the widespread applications of aqueous rechargeable Ni-Zn batteries. Herein, a facile strategy has been employed to construct hierarchical Co-doped Ni-MoO4 nanosheets as the cathode for high-performance Ni-Zn battery. Benefiting from the merits of substantially improved electrical conductivity and increased concentration...... hiện toàn bộ
CoSe2 nanoparticles-decorated carbon nanofibers as a hierarchical self-supported sulfur host for high-energy lithium-sulfur batteries
Science China Materials - Tập 66 - Trang 3075-3083 - 2023
Juan Ao, Yonghui Xie, Yunda Lai, Ming Yang, Jing Xu, Fan Wu, Shuying Cheng, Xinghui Wang
Lithium-sulfur (Li-S) batteries have gained widespread attention owing to their high theoretical energy density and low cost. However, the commercial application of these batteries is hindered by the severe shuttle effect and slow redox reaction kinetics of polysulfides. In this study, a hierarchically porous membrane consisting of CoSe2 nanoparticle-decorated carbon nanofibers containing carbon n...... hiện toàn bộ
