| 1 | Extraordinarily stable and wide-temperature range sodium/potassium-ion batteries based on 1D SnSe2-SePAN composite nanofibers显示文摘Developing electrodes with long lifespan and wide-temperature adaptability is crucial important to achieve high-performance sodium/potassium-ion batteries(SIBs/PIBs).Herein,the SnSe2-SePAN composite was fabricated for extraordinarily stable and wide-temperature range SIBs/PIBs through a coupling strategy between controllable electrospinning and selenylation,in which SnSe2 nanoparticles were uniformly encapsulated in the SePAN matrix.The unique structure of SnSe2-SePAN not only relieves drastic volume variation but also guarantees the structural integrity of the composite,endowing SnSe2-SePAN with excellent sodium/potassium storage properties.Consequently,SnSe2-SePAN displays a high sodium storage capacity and excellent feasibility in a wide working temperature range(-15 to 60℃:300 mAh g^(-1)/700 cycles/-15℃;352 mAh g^(-1)/100 cycles/60℃at 0.5 A g^(-1)).At room temperature,it delivers a record-ultralong cycling life of 192 mAh g^(-1)that exceeds 66000 cycles even at 15 A g^(-1).It exhibits extremely superb electrochemical performance in PIBs(157 mAh g^(-1)exceeding 15000 cycles at 5 A g^(-1)).The ex situ XRD and TEM results attest the conversion-alloy mechanism of SnSe2-SePAN.Also,computational calculations verify that SePAN takes an important role in intensifying the electrochemical performance of SnSe2-SePAN electrode.Therefore,this study breaks new ground on solving the polyselenide dissolution issue and improving the wide temperature workable performance of sodium/potassium storage. | Yiyi Wang Fuyu Xiao Xi Chen Peixun Xiong Chuyuan Lin Hong-En Wang Mingdeng Wei Qingrong Qian Qinghua Chen Lingxing Zeng | 2023 | InfoMat2023，5，9： | 1 |
| 2 | Progress in Electrolyte Engineering of Aqueous Batteries in a Wide Temperature Range显示文摘Aqueous rechargeable batteries are safe and environmentally friendly and can be made at a low cost;as such,they are attracting attention in the field of energy storage.However,the temperature sensitivity of aqueous batteries hinders their practical application.The solvent water freezes at low temperatures,and there is a reduction in ionic conductivity,whereas it evaporates rapidly at high temperatures,which causes increased side reactions.This review discusses recent progress in improving the performance of aqueous batteries,mainly with respect to electrolyte engineering and the associated strategies employed to achieve such improvements over a wide temperature domain.The review focuses on fi ve electrolyte engineer-ing(aqueous high-concentration electrolytes,organic electrolytes,quasi-solid/solid electrolytes,hybrid electrolytes,and eutectic electrolytes)and investigates the mechanisms involved in reducing the solidifi cation point and boiling point of the electrolyte and enhancing the extreme-temperature electrochemical performance.Finally,the prospect of further improving the wide temperature range performance of aqueous rechargeable batteries is presented. | Lingjun He Chuyuan Lin Peixun Xiong Hui Lin Wenbin Lai Jingran Zhang Fuyu Xiao Liren Xiao Qingrong Qian Qinghua Chen Lingxing Zeng | 2023 | Transactions of Tianjin University2023，29，5： | 0 |
