Membrane Electrode

A novel membrane electrode was fabricated by coating conductive slurry (K/Graphene composites as its important component) on copper foil. The membrane electrode, as anode of lithium ion battery, exhibited excellent columbic efficiency and specific capacity of 831 mAh g-1 after 1000 cycles. The K/Graphene composites presented a multi-layer nanostructure. It provided not only more intercalation space and intercalation sites for Li+ during the Li+ intercalation/extraction, but also alleviated the agglomeration of dispersed nanocrystals, as well as decreased the electrochemical impedance. The results suggest that the membrane electrode holds great potential as an anode material for LIBs.

Curaua Fibers

A statistical evaluation based on the Weibull method was performed to correlate the mechanical properties and the diameter of different lignocellulosic fibers. The sisal, rami and curaua fibers were found to have a hyperbolic correlation between their ultimate strength and diameter. This permitted to select thinner high strength fibers, with over 1000 MPa, as reinforcement for the strongest polymer composites ever fabricated with these fibers. A structural analysis was conducted by electron microscopy to identify the strengthening mechanism for both, the high performance fiber and their improved polymer composites.
