Infrared Drying Characteristics of Graphite Anode Coatings for Lithium Batteries

The infrared drying characteristics of graphite anode coatings for lithium batteries were studied experimentally. The influence of infrared heat source power and radiation distance on drying characteristics of graphite anode coatings and energy consumption of the system were explored. The experimental results show that the drying process of the coatings can be divided into three stages: increasing speed, constant speed and decreasing speed, and there is a linear relationship between the critical moisture content of the coatings and the thickness change of the coatings during drying. Under the experimental conditions, the radiation distance and heat source power have the following effects on the drying rate of the coating: the greater the power and the smaller the distance, the greater the drying rate of the pole. Based on the above experimental results, the reasons for their formation are analyzed and discussed, and the optimum drying parameters of the system are put forward: infrared heat source power 150W, radiation distance 155mm.
