Gas furnace for lithium battery cathode material and production method

Abstract

The invention relates to the field of lithium battery cathode material processing, in particular to a gas furnace for a lithium battery cathode material and a production method. The gas furnace comprises a shell and a rotating mechanism, fixing plates are installed on the two sides of the shell through bolts, gas igniters are installed at the tops of the fixing plates through bolts, and blowpipes are welded to the output ends of the gas igniters. Controllers are installed on the two sides of the shell through bolts, the output ends of the controllers are electrically connected with the gas igniters through electric leads, temperature thermocouples are inserted into the two sides of the shell, a side plate mechanism is arranged on one side of the shell, the bottom of the side plate mechanism is rotationally connected with a side wall supporting shaft, and a refractory material layer is arranged in the shell. A combustion chamber is arranged in the refractory material layer. The gas furnace has the beneficial effects that the comprehensive energy efficiency of the gas furnace is higher than that of traditional electric heating equipment, the gas furnace is short in heating and cooling time and high in speed, production starting and stopping are flexible, the interior of the gas furnace is conveniently cleaned, and the problem that the energy efficiency of the gas furnace is reduced is solved.

Description

technical field [0001] The invention relates to the field of lithium battery cathode material processing, in particular to a gas furnace and a production method for lithium battery cathode materials. Background technique [0002] Lithium-ion batteries are widely used in communications, electric tools, electric bicycles and electric vehicle power batteries and other fields. Cathode material is the key material of lithium-ion battery. The cost of cathode material accounts for about 20%-50% of the cost of lithium-ion battery, and the performance of cathode material also largely determines the overall performance of lithium-ion battery. [0003] The current production process of lithium-ion battery cathode materials is mostly produced by high-temperature solid-phase method; the production equipment used is mostly heated roller furnace and pusher furnace. However, my country's electricity is mainly based on thermal power generation, and devices that require a large amount of hea...
