Description

Technical Field

[0001] The invention belongs to the technical field of conductive slurry production equipment, and in particular relates to a high-performance graphene composite conductive slurry production device. Background Art

[0002] Graphene, a magical material composed of a single layer of tightly arranged carbon atoms, has attracted much attention since its discovery due to its unique physical and chemical properties. Its electrical, mechanical, optical and thermal properties are extremely excellent, making it show great application potential in many fields. In composite materials, graphene can enhance the strength and toughness of materials; in energy storage materials, it can improve the capacity and charge and discharge efficiency of batteries; in electronic devices, it can be used as a high-performance conductive material; even in the field of biomaterials, graphene shows great potential due to its unique biocompatibility and bioactivity.

[0003] Although graphene has so many advantages, it faces a severe challenge in its practical application - agglomeration. Graphene dry powder is easy to restack and agglomerate during the drying process, which greatly weakens its excellent performance. In order to solve this problem, scientists have used a series of methods, such as using dispersants and solvents, to redisperse graphene dry powder into conductive slurry. This method has improved the agglomeration phenomenon of graphene to a certain extent, allowing the excellent performance of graphene to be better exerted. However, there are still some problems in the preparation and application of graphene conductive slurry. Due to the high viscosity of the conductive slurry, when additives such as conductive carbon black powder are mixed into the slurry, the performance of subsequent products is often affected due to uneven mixing. This is mainly due to the lack of dedicated mixing equipment, which makes it impossible for the additives to be evenly distributed in the slurry.
