Description

Technical Field

[0001] The utility model relates to the technical field of the production of positive electrode materials for sodium ion batteries, in particular to a novel sintering device for positive electrode materials of sodium ion batteries. Background Technique

[0002] At present, the electric track kiln is a kind of thermal equipment widely used in the battery anode and cathode material industries. It is a high-energy-consuming equipment that mainly uses electricity as its heat source. The heat source of the electric track kiln mainly uses electric heating rods for heating. The electric heating rods not only have a relatively high production cost themselves, but also are prone to attenuation after long-term use and need to be frequently replaced, further increasing the use cost, and generally need to be replaced once every 3 - 4 months. In addition, in order to ensure the sintering atmosphere, achieve the sealing effect, and prevent material pollution caused by metals such as copper and zinc, the shell of the sintering equipment needs to use stainless steel material, resulting in high fixed investment costs;

[0003] The publication number CN219995866U discloses a novel sintering device for positive electrode materials of sodium ion batteries, including a kiln body and a feeding mechanism; the kiln body includes a furnace cavity and a combustion cavity. The combustion cavity is provided with an output structure for providing heat to the furnace cavity, and the combustion cavity is also connected with a combustible fuel conveying structure;

[0004] When in use, after the sintering of the positive electrode material of the sodium ion battery is completed, it is necessary to wait for the high temperature inside the device box to decrease, which makes it not easy for personnel to be scalded when taking materials, but the waiting time is relatively long and a large amount of heat is lost. Therefore, we propose a novel sintering device for positive electrode materials of sodium ion batteries. Content of the Utility Model
