Lithium battery baking oven

Abstract

The invention discloses a lithium battery round baking oven, which comprises a case and an oven body arranged in the case, wherein the oven body uses a round structure; a heater and a heat insulation layer are arranged on the inner wall of the case; an air inlet opening and an air outlet opening are formed in the top of the case; a blower device positioned on the top of the oven body is arranged in the case, and is connected with a motor; when the blower device is driven by the motor, eddy current is generated between the case and the oven body; after a plurality of exhaust holes are formed in the oven body, high-speed flowing hot air is formed in the oven body, so that each corner in the oven body can receive heat radiation; in addition, the heated condition is uniform; the baking effect is greatly improved. A certain number of adsorbent fiber materials are arranged on the inner wall of the oven body. The lithium battery round baking oven has the characteristics that the battery temperature can fast reach the process baking temperature; drying and dewatering are performed; the cost is lower; the humidity and temperature control on the external environment is not needed; the equipment and the energy sources are saved; the baking cost is reduced.

Description

technical field [0001] The invention belongs to the field of drying equipment, and in particular relates to a lithium battery baking equipment. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to its high working voltage, small size, light weight, high energy, no memory effect, no pollution, small self-discharge, and long cycle life, lithium-ion batteries are ideal energy carriers for development in the 21st century. [0003] In the production process of lithium batteries, the moisture content of its raw materials must be strictly controlled, because the electrolyte of lithium batteries is an organic substance without water molecules, and the existence of moisture has a great impact on the battery, including voltage, internal resistance, self-discharge and other indicators. Excessive moisture content can lead to product rejection, qu...

Problems solved by technology

[0004] The above two ovens are used to remove water. The first type requires special vacuum equipment and nitrogen source as support, and has high requirements on the sealing performance of the box. The baking process requires a lot of vacuum and nitrogen (or argon, It is used to break the vacuum) resources, resulting in higher baking costs, and the heating is transmitted through thermal radiation, the temperature difference between different areas of the oven is large, and the baking effect is poor; the second type is the need to control the external environment Humidity, additional equipment is required to control the humidity of the environment, and the heat cannot be recovered, which constitutes a waste of energy and higher baking costs
