Abstract: A graphene heat-dissipation LED lamp, comprising an LED light source module, a power supply module, a lamp housing (9) and a waterproof power strip (22). The LED light source module is connected to the power supply module by means of the power strip (22) to form an LED module assembly. A graphene heat-conducting material is added to the LED module, so that the heat conduction efficiency is improved and the service life is prolonged. In addition, the lighting performance of the LED lamp is further improved. By configuring independent modules and using a quick connector, the LED lamp can be quickly mounted without a disassembling tool.

Abstract: Provided is a method for preparing a graphene/ternary material composite for use in lithium ion batteries, comprising the following preparation steps: (a) mixing a ternary material and a graphene oxide powder in an organic solvent to form a mixed dispersion; (b) adding a reducing agent to the mixed dispersion from step (a), and carrying out a reduction reaction at a reduction temperature of 80-160° C. while stirring, to obtain a reduction reaction mixture after a reduction time of 60-240 min; and (c) evaporating the solvent from the reduction reaction mixture from step (b) while stirring, and drying and then annealing the mixture at a low temperature in an inert atmosphere to obtain a graphene/ternary material composite having a three-dimensional network structure.

Abstract: An aluminum laminated packaging film, and lithium-ion battery using same. The aluminum laminated film (1) comprises an aluminum layer (12), a graphene layer (14), and a sealing layer (13) in sequence. The graphene layer (14) comprises graphene sheets and a thermoplastic polymer adhesive. The platelet structure of the graphene and irregular arrangement of the graphene enable locations between sheets to form indirect and complex paths, creating a huge barrier for lithium ions moving toward the aluminum layer, thus preventing the lithium ions from forming aluminum-lithium alloy with the metal aluminum, and avoiding corrosion of the aluminum layer (12).
