Grinding-modification integrated production device and technique, and application thereof

Abstract

The invention relates to a grinding-modification integrated production device and production technique. The grinding-modification integrated production device comprises a stirrer (1), a size mixing tank (2), a pump (3), a filter unit (6) and a heating drier (7), wherein the upper end of the stirrer (1) is communicated with the upper end of the size mixing tank (2) through a channel (4); the pump (3) is respectively connected with the stirrer (1) and size mixing tank (2) through pipelines; a plurality of metal balls and zirconium balls are arranged in the stirrer (1); the filter unit (6) is positioned on the downstream of the stirrer (1); and the heating drier (7) is positioned on the downstream of the filter unit (6). The grinding-modification integrated production device can integrate grinding and modification, can simplify the technical process, can save the equipment investment, and is applicable to the field of graphite deep finishing.

Description

technical field [0001] The invention belongs to the field of conductive materials, in particular to the field of graphite electrode materials. Background technique [0002] Graphite is an allotrope of elemental carbon. The periphery of each carbon atom is connected with three other carbon atoms (multiple hexagons arranged in a honeycomb pattern) to form a covalent molecule. Graphite is an electrical conductor because each carbon atom emits an electron and those electrons are free to move. Graphite is one of the softest minerals, and its uses include making carbon brushes, anode materials for lithium-ion batteries, and more. [0003] Graphene is a two-dimensional carbon material, which is a general term for single-layer graphene, double-layer graphene and multi-layer graphene. It came out in 2004. Two scientists from the University of Manchester, Andre Jem and Kostya Novoselov found that they could obtain thinner and thinner graphite flakes in a very simple way. As a resul...

Problems solved by technology

[0004] In the existing graphite deep-finishing process, graphite powder is usually jet-milled into particles. When the graphite particles are stacked together, the surface of the graphite particles is not smooth, some have edges and corners, and some are wrinkled and irregular. shape, the direction of graphite particles is inconsistent, when used as a conductor to conduct electricity, the resistivity increases, and the material is prone to heat; when used as a heat-conducting material, the thermal conductivity will be compromised
