    摘要： The synthesis of layered freestanding papers composed of acid-functionalized, few-layer molybdenum disulfide (MoS2) and reduced graphene oxide (rGO) flakes for use as a binder-free conducting electrode in NIB applications are described. The mechanical and electrochemical performance of the layered freestanding papers is also described. Synthesis was achieved through vacuum filtration of highly homogenous dispersions comprising varying weight percentages of exfoliated MoS2 flakes in graphene oxide in DI water, followed by thermal reduction. The electrochemical behavior of the composite paper was evaluated as a counter electrode against pure Na foil in a half-cell configuration. In addition, the uniaxial tensile testing of the composite papers demonstrated their exceptionally high fracture strength.

    摘要： The synthesis of layered free-standing papers, films, tapes, and painted coatings. composed of acid-functionalized, few-layer molybdenum disulfide (MoS2) and reduced graphene oxide (rGO) flakes for use as a binder-free conducting electrode in NIB applications are described. The mechanical and electrochemical performance of the layered free-standing papers is also described. Synthesis was achieved through vacuum filtration of highly homogenous dispersions comprising varying weight percentages of exfoliated MoS2 flakes in graphene oxide in DI water, followed by thermal reduction. The electrochemical behavior of the composite paper was evaluated as a counter electrode against pure Na foil in a half-cell configuration. In addition, the unaxial tensile testing of the composite papers demonstrated their exceptionally high fracture strength.

    摘要翻译： 分层自立纸，薄膜，胶带和涂漆的合成。 描述了在NIB应用中用作无粘合剂的导电电极的酸官能化的少层二硫化钼（MoS2）和还原型氧化石墨（rGO）薄片。 还描述了层状自立式纸的机械和电化学性能。 通过真空过滤高度均匀的分散体来实现合成，所述高均匀分散体包含不同重量百分比的去离子水中氧化石墨烯中的剥离的MoS2薄片，然后进行热还原。 复合纸的电化学行为被评估为与半电池构型中的纯Na箔相反的对电极。 此外，复合材料纸的单轴拉伸试验显示出其特别高的断裂强度。
