Abstract

The invention discloses a thermal-method powdery electrode printing material. The thermal-method powdery electrode printing material is prepared from the following raw materials in percentage by mass: any one of nickel cobalt lithium manganite, lithium manganite, lithium cobaltate, lithium iron phosphate, lithium titanate and graphite, which accounts for 79.5 percent to 98.57 percent of the total mass; any one of graphene, a carbon nanotube, onion carbon and a nano silver wire, serving as an electrode enhancing phase, which accounts for 1 to 10 percent of the total mass; phenol-formaldehyde resin powder which accounts for 0.3 percent to 5.0 percent of the total mass; urotropine which accounts for 10 percent of the amount of the phenol-formaldehyde resin; any one of calcium stearate and zinc stearate, which accounts for 0.1 percent to 0.5 percent of the total mass, wherein the total sum is 100 percent. The invention further discloses a preparation method of a printing electrode of the thermal-method powdery electrode printing material. The printing material disclosed by the invention has the advantages that a selection range of the raw materials is wide and a process is simple; the shape of an electrode can be finely controlled within a micro-scale dimension and the electrochemical performance is good.

Description

technical field [0001] The invention belongs to the technical field of material forming, and relates to a thermal powder electrode printing material, and also relates to a preparation method of the thermal powder electrode printing material printing electrode. Background technique [0002] In recent years, with the increasing popularity of miniaturized devices such as sensors, wireless transmission equipment, personal health monitoring systems, and micro-electromechanical systems, the demand for matching miniature power components has also increased. As a general-purpose electronic device, a battery is an essential part of various instruments and equipment. Traditional batteries are often prismatic, cylindrical or coin-shaped, which are bulky and not portable enough, making them unable to adapt to miniaturized equipment in various industries. demand. In order to adapt to the development and needs of various electronic devices, scholars from various countries have launched r...
