水系二次电池因其安全性高、成本低以及对环境友好等特点,在大规模储能领域展现出广阔的应用前景。电极材料作为电池的关键组成部分,其性质直接影响电池电化学性能。锰氧化物具有晶体结构丰富、理论比容量高、氧化还原电位高、成本低等优势,被认为是最具发展潜力的正极材料之一。然而,锰氧化物存在导电性差、结构不稳定、锰溶解等问题,使电池面临倍率和循环性能差的严峻挑战,限制了其实际应用。此外,锰氧化物的反应机制较为复杂。针对上述问题,本文通过调研有关锰氧化物的文献,首先分析了其晶体结构类型和特点,进一步按照电解液酸度梳理归纳了锰氧化物在(弱)酸性和碱性条件下的反应机制,简要阐述了其在水系碱金属离子、多价金属离子以及非金属离子二次电池体系的研究进展,最后对未来高性能锰氧化物正极的发展方向进行了展望。

为克服不锈钢摩擦副零件摩擦因数大、易磨损的不足,利用粉末冶金不锈钢基体贯通孔隙特征和异质结纳米润滑剂超滑效应,采用真空浸渍和水热合成两步法工艺制备出了MoSe_(2)/石墨烯-不锈钢自润滑材料,并对其摩擦学特性与减摩机理进行了研究。研究发现:摩擦过程中,加入到基体孔隙的MoSe_(2)/石墨烯异质结润滑剂在摩擦表面形成了均匀润滑膜,显著减小了摩擦副的摩擦因数和磨损率。在常温、载荷40 N、转速100 r/min工况下,MoSe_(2)/石墨烯-不锈钢自润滑材料的摩擦因数低至0.106,磨损率降至6.45×10^(-5)mm^(3)/(N·m),与不锈钢基体相比,其摩擦因数和磨损率分别降低了86%和93%。
