摘要:
Disclosed is an electrode assembly of a lithium secondary battery, including an anode plate, a cathode plate, a separator for separating the anode plate and the cathode plate and conducting lithium ions of an electrolyte, and a composite film disposed between the anode plate and the separator and/or between the cathode plate and the separator. The composite film includes 5 to 95 parts by weight of an inorganic clay and 95 to 5 parts by weight of an organic polymer binder.

Disclosed are encapsulation materials including an 80 to 99.5 weight percentage (wt %) of ethylene vinyl acetate copolymers (EVA) and a 0.5 to 20 weight percentage(wt %) of a photoluminescent polymer, wherein the EVA and the photoluminescent polymers are evenly blended. The encapsulation materials can be applied to packaging solar cells, and the encapsulating structure may protect the EVA from UV damage and enhance light utilization efficiency of the solar cell.

A manufacturing method for manufacturing a substrate with a surface substrate by employing photothermal effect is described. Nanoparticles on the surface of the substrate excited by a beam convert light energy to thermal energy. The surface structure on the substrate is formed through the thermal energy generated by the excited nanoparticles. The substrate with a layer of the predetermined pattern is thus formed.

A composition of a thermal interface material is provided. The deficiencies of low thermal conductivity and high thermal resistance in the conventional thermal interface materials are resolved. By using carbon fibers with high thermal conductivity, the thermal conductivity of the thermal interface material can be about 7˜10 times higher than the traditional thermal interface materials. The added amount of carbon fibers is less than the added amount of metal or ceramic powders. The dispersion process is thereby improved. Further, the thermal interface material has a phase change temperature at about 40˜65° C. Holes, gaps and dents on the surface of device are filled at the normal operation temperature of device to reduce the thermal resistance of the entire device and to increase the interfacial bonding strength.

The invention provides a halogen-free and thermal resistant composition, including a mixture of bismaleimide and maleimide with molar ratio of 99:1-50:50; a barbituric acid, wherein the molar ratio of the mixture and the barbituric acid is 93:7-80:20; and an epoxy resin, wherein (the mixture with the barbituric acid) and the epoxy resin have a weight ratio of 5:95 to 50:50. The mixture undergoes reaction at 110-130° C. for about 2˜7 hours to form a maleimide modified epoxy resin. The procedure of forming the composition is solvent-free, thereby providing improved integrity for electronic packaging, lower curing temperature, and a simplified process.
