项目摘要
All-solid state lithium secondary batteries are strongly desired as novel power sources with high performances because these solvent-free systems have higher safety and higher reliability than conventional lithium secondary batteries with liquid electrolytes. Thio-LISICON (LIthium SuperIonic CONductor), Li4-x Gel-x Px S4 is one of the best lithium ion conductive solids ever found in inorganic materials, and has sufficiently high conductivity, transport number, decomposition potential and thermal stability for practical use in battery. The purpose of the present study is to develop the all solid-state battery having excellent charge-discharge performance at high current density, and to characterize the interfacial behavior at various anode/electrolyte interfaces. The solid electrolyte interface (SEI) was found at Li-Al alloy/Li3.25Ge0.25P0.75S4 interface by x-ray diffraction pattern, x-ray photoelectron spectroscopy, ac impedance, and scanning electron microscopy. The SEI allowed the fastest electrochemical reaction between the anode and the electrolyte during charge-discharge process.The surface reaction and reaction mechanism of the lithium intercalation electrodes were studied using epitaxial cathode films of LiMO_2 (M=Co, Ni) and LiMn_2O_4 oxides with the layered rock-salt type and the spinel structure, respectively. The electrode films were successfully deposited on single crystal SrTiO_3 substrates by PLD method. The orientation of the epitaxial films was controlled with the substrate orientation. The anisotropic characteristics of lithium intercalation reaction and surface reaction for their cathode materials were clarified by in-situ synchrotron X-ray diffraction and reflectivity measurements in beam-line 14B1 at SPring-8.
全固态锂二次电池作为高性能的新型电源是人们强烈的需求,因为这些无溶剂系统比传统的液体电解质锂二次电池具有更高的安全性和可靠性。 Thio-LISICON(锂超离子导体),Li4-x Gel-x Px S4 是迄今为止在无机材料中发现的最好的锂离子导电固体之一,具有足够高的电导率、输运数、分解电位和热稳定性,适合在电池中实际使用。本研究的目的是开发在高电流密度下具有优异充放电性能的全固态电池,并表征各种阳极/电解质界面的界面行为。通过X射线衍射图、X射线光电子能谱、交流阻抗和扫描电子显微镜,在Li-Al合金/Li3.25Ge0.25P0.75S4界面处发现了固体电解质界面(SEI)。 SEI使得充放电过程中阳极和电解液之间发生最快的电化学反应。分别采用层状岩盐型和尖晶石结构的LiMO_2(M=Co,Ni)和LiMn_2O_4氧化物外延正极薄膜研究了插锂电极的表面反应和反应机理。采用PLD方法在单晶SrTiO_3基底上成功沉积了电极薄膜。外延膜的取向由衬底取向控制。通过原位同步加速器 X 射线衍射和 SPring-8 束线 14B1 反射率测量,阐明了其正极材料的锂嵌入反应和表面反应的各向异性特征。
