| 1 | Nanostructured transition metal nitride composites as energy storage material显示文摘There are growing demands for the next generation lithium ion batteries with high energy density as well as high power performance for renewable energy storage and electric vehicles application.Recently,nanoscale materials with outstanding energy storage capability have received considerable attention due to their unique effect caused by the reduced dimensions.This review describes some recent developments of our group in research of transition metal nitride nanocomposites in application of energy storage,especially for lithium ion battery and supercapacitor.The strategies of mixed conduction(electron and ion) network with a favorable charge transportation interface in the design of the nanocomposites for such devices are highlighted. | YUE YanHua HAN PengXian DONG ShanMu ZHANG KeJun ZHANG ChuanJian SHANG ChaoQun CUI-GuangLei | 2012 | Chinese Science Bulletin2012，57，32： | 3 |
| 2 | An insight into failure mechanism of NASICON-structured Na3V2(PO4)3 in hybrid aqueous rechargeable battery显示文摘NASICON (Na-super-ionic-conductors)-structured materials have attracted extensive research interest due to their great application potential in secondary batteries. However, the mechanism of capacity fading for NASICON-structured electrode materials has been rarely studied. In this paper, we synthesized the NASICON-structured Na3V2(PO4)3/C composite by simple sol-gel and high-temperature solid-phase method and investigated its electrochemical performance in Na-Zn hybrid aqueous rechargeable batteries. After characterizing the structure, morphology and composition variations as well as the interfacial resistance changes of Na3V2(PO4)3/C cathode during cycling, we propose a mechanical and interfacial degradation mechanism for capacity fading of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries. This work will shed light on enhancing the mechanical and in terfacial stability of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries. | Xinxin Zhang Jun Ma Pu Hu Bingbing Chen Chenglong Lu Xinhong Zhou Pengxian Han Lihua Chen Guanglei Cui | 2019 | Journal of Energy Chemistry2019，28，5： | 3 |

| 5 | Optimization on transport of charge carriers in cathode of sulfide electrolyte-based solid-state lithium-sulfur batteries显示文摘Lithium-sulfur(Li-S)batteries are considered as promising candidates for novel energy storage technology that achieves energy density of 500 Wh·kg^(−1).However,poor cycle stability resulting from notorious shuttle effect and the safety concerns deriving from flammability of ether-based electrolyte hinder the practical application of Li-S batteries.Because of low solubility to polysulfide,high ionic conductivity,and safety property,sulfide-based electrolytes can fundamentally address above issues.It is widely known that the effective transports of both electrons and ions are basic requirement for redox reaction of active materials in cathode.Thereby,construction of fast and stable ionic and electronic transport paths in cathode is especially pivotal for cycle stability of solid-state Li-S batteries(SSLSBs).In this review,we provide research progresses on facilitating transport of charge carriers in composite cathode of SSLSBs.From perspective of materials,intrinsically conductivity of electrolyte and carbon shows dramatic effect on migration of charge carriers in cathode of SSLSBs,thereby the conductive additives are summarized in the manuscript.Additionally,the charge transport in cathode of SSLSBs fully depends on the physical contact between active materials and conductive additives,therefore we summarized the strategies optimizing interfacial contact and reducing interfacial resistance.Finally,potential future research directions and prospects for SSLSBs with improved energy density and cycle performance are also proposed. | Zengqi Zhang Yantao Wang Tao Liu Gang Li Jun Ma Jianjun Zhang Pengxian Han Shanmu Dong Xuedong Yan Yue Tang Guanglei Cui | 2023 | Nano Research2023，16，6： | 0 |
