| 1 | Building Ultra-Stable and Low-Polarization Composite Zn Anode Interface via Hydrated Polyzwitterionic Electrolyte Construction显示文摘Aqueous zinc metal batteries are noted for their costeffectiveness,safety and environmental friendliness.However,the water-induced notorious issues such as continuous electrolyte decomposition and uneven Zn electrochemical deposition remarkably restrict the development of the long-life zinc metal batteries.In this study,zwitterionic sulfobetaine is introduced to copolymerize with acrylamide in zinc perchlorate(Zn(ClO;);)solution.The designed gel framework with hydrophilic and charged groups can firmly anchor water molecules and construct ion migration channels to accelerate ion transport.The in situ generated hybrid interface,which is composed of the organic functionalized outer layer and inorganic Clcontaining inner layer,can synergically lower the mass transfer overpotential,reduce water-related side reactions and lead to uniform Zn deposition.Such a novel electrolyte configuration enables Zn//Zn cells with an ultra-long cycling life of over 3000 h and a low polarization potential(~0.03 V)and Zn//Cu cells with high Coulombic efficiency of 99.18%for 1000 cycles.Full cells matched with MnO;cathodes delivered laudable cycling stability and impressive shelving ability.Besides,the flexible quasi-solid-state batteries which are equipped with the anti-vandalism ability(such as cutting,hammering and soaking)can successfully power the LED simultaneously.Such a safe,processable and durable hydrogel promises significant application potential for long-life flexible electronic devices. | Qiong He Guozhao Fang Zhi Chang Yifang Zhang Shuang Zhou Miao Zhou Simin Chai Yue Zhong Guozhong Cao Shuquan Liang Anqiang Pan | 2022 | Nano-Micro Letters2022，14，6： | 1 |
| 2 | Biodegradable composite polymer as advanced gel electrolyte for quasi-solid-state lithium-metal battery显示文摘The development of low-cost and eco-friendly gel polymer electrolytes (GPEs) with a wide window, ideal compatibility, and structural stability is an effective measure to achieve safe high-energy-density lithium-metal batteries. Herein, a biodegradable composite polyacrylonitrile/poly-L-lactic acid nanofiber membrane (PAL) is synthesized and used as a robust skeleton for GPEs. The 3D nanofiber membrane (PAL-3-C12) prepared with an adjusted weight ratio of polyacrylonitrile (PAN)/poly-L-lactic acid (PLLA) and spinning solution concentration delivers decent thermal stability, biodegradability, and liquid electrolyte absorbability. The “passivation effect” of PAN upon lithium metal is effectively alleviated by hydrogen bonds formed in the PAL chains. These advantages enable PAL GPEs to work stably to 5.17 V while maintaining high ionic conductivity as well as excellent corrosion resistance and dielectric properties. The interfacial compatibility of optimized GPEs promotes the stable operation of a Li||PAL-3-C12 GPEs||Li symmetric battery for 1000 h at 0.15 mA cm^(−2)/0.15 mA h cm^(−2), and the LiFePO4 full cell retains capacity retention of 97.63% after 140 cycles at 1C. | Simin Chai Yangpu Zhang Yijiang Wang Qiong He Shuang Zhou Anqiang Pan | 2022 | eScience2022，2，5： | 0 |
