Abstract Recent development of manganese-lithium borate glasses for applications as supercapacitor was reported. The glasses were prepared by melt-quench technique and characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), and Uv–visible spectroscopy (UV-VIS). The paramagnetism of synthesized glasses was observed at room temperature measured by vibrating sample magnetometry (VSM). The electrochemical properties were studied by cyclic voltammetry (CV). The specific capacitance of 0.2MnO2-0.8(Li2O-xB2O3) glasses were increase from 144 F g−1 to 196 F g−1 for x = 1 to x = 3 (mol%) with scanning rate of 5 mV s−1. However, the specific capacitance was decrease when x = 4. To understand the structure-function of these glasses, the x-ray absorption spectroscopy (XAS) was also used to study a local structure and oxidation state of Mn content in these glasses. Mixing of Mn2+/Mn3+ oxidation state was exhibited with the mean Mn–O bonding distance of approximately 2.0495 A.

摘要 报道了用于超级电容器应用的锰-锂硼酸盐玻璃的最新发展。玻璃采用熔融淬火技术制备，并通过 X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 和紫外-可见光谱 (UV-VIS) 进行表征。通过振动样品磁强计（VSM）在室温下观察合成玻璃的顺磁性。通过循环伏安法（CV）研究电化学性质。0.2MnO2-0.8(Li2O-xB2O3) 玻璃的比电容从 144 F g-1 增加到 196 F g-1，x = 1 到 x = 3 (mol%)，扫描速率为 5 mV s-1。然而，当 x = 4 时，比电容下降。为了了解这些玻璃的结构 - 功能，X 射线吸收光谱 (XAS) 也用于研究这些玻璃中 Mn 含量的局部结构和氧化态。Mn2+/Mn3+ 氧化态的混合表现出平均 Mn-O 键合距离约为 2.0495 A。
