Nitrogen doping has been shown to greatly improve the stability of solid electrolyte (SE) materials at the anode and cathode interfaces in all solid-state batteries (ASSBs) as widely demonstrated by the LiPON family of compositions. In an effort to expand the use of nitrogen in SEs, in this study, mixed oxy-sulfide nitride (MOSN) glasses were prepared by direct ammonolysis of the sodium oxy-sulfide phosphate Na4P2S7-xOx (NaPSO) glass series to understand the combined effects that oxygen and sulfur have on the incorporation of nitrogen. The short-range order (SRO) structures of the Na4P2S(7-x)-3/2yzOx-3/2y(1-z)Ny (NaPSON) glasses were investigated with Raman and infrared (IR) spectroscopies to understand the effect that nitrogen has in the glass structure. The N content of the glasses was quantified by elemental analysis and confirmed through weight change measurements. By combining this information, it was further possible to determine the anion exchange ratio, z, for the N substitution of O and S as a function of the base NaPSO glass chemistry, x. The composition-dependent glass transition temperature, Tg(x), measured with differential scanning calorimetry (DSC), was found to correlate well with the measured N/P ratio, y, in the NaPSON glasses.

混合氧硫化物氮化物 (MOSN) 玻璃的合成、短程有序结构和热性能

正如 LiPON 系列组合物所广泛证明的那样,氮掺杂已被证明可以大大提高所有固态电池 (ASSB) 中阳极和阴极界面处固体电解质 (SE) 材料的稳定性。为了扩大氮在 SE 中的使用,在本研究中,通过氧硫化钠磷酸钠 Na 4 P 2 S 7- x O x (NaPSO) 的直接氨解制备了混合氧硫化物氮化物 (MOSN) 玻璃玻璃系列以了解氧和硫对氮结合的综合影响。Na 4 P 2 S (7- x )-3/2 yz O的短程有序 (SRO) 结构x -3/2 y (1- z ) N y (NaPSON) 玻璃用拉曼光谱和红外 (IR) 光谱进行研究,以了解氮对玻璃结构的影响。玻璃的 N 含量通过元素分析进行​​量化,并通过重量变化测量进行确认。通过结合这些信息,可以进一步确定阴离子交换比z,即 O 和 S 的 N 取代作为基础 NaPSO 玻璃化学x 的函数。依赖于组成的玻璃化转变温度, T g ( x),用差示扫描量热法 (DSC) 测量,发现与NaPSON 玻璃中测量的 N/P 比y 有很好的相关性。
