Problems solved by technology

In terms of battery design, a complete process is often used to produce new products after the new design. The production of new products requires frequent adjustments to the production parameters of the machines on the production line. At the same time, the production cycle is long and the cost of sample preparation is high. Not conducive to the development and design of batteries

Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0027] Such as figure 1 Shown is a method of 3D printing the positive electrode, negative electrode and electrolyte of the battery. The method uses 3D printing of the positive electrode, negative electrode and electrolyte of the battery, and forms a battery cell through lamination.

[0028] The positive electrode printing of the battery comprises the following steps:

[0029] S11: 3D printing the first paste on the aluminum foil;

[0030] S12: Bake at a temperature of 120° for 2 minutes to dry the paste on the first side;

[0031] S13 Turn over the aluminum foil and 3D print the second paste;

[0032] S14: Bake at a temperature of 120° for 2 minutes, and dry the paste on the second side to print the electrolyte.

[0033] The printing of...

Abstract

The invention discloses a three-dimensional (3D) printing method for a cathode, an anode and an electrolyte of a battery. According to the method, the cathode, the anode and the electrolyte of the battery are printed in a 3D manner, and a battery core is formed through lamination. According to the method, the cathode, the anode and the electrolyte of the battery are printed in the 3D manner, and the battery core is formed through lamination, so that the production of new products is carried out without adjusting the production parameters of machines on the production line, the production cycle is short, sample preparation can be completed within 24 hours, the sample preparation cost is low, the design is flexible, the rate of development is high, and different design samples can be quickly manufactured.

Description

technical field [0001] The invention relates to the field of battery production, in particular to a method for 3D printing a positive electrode, a negative electrode and an electrolyte of a battery. Background technique [0002] With the development of microelectronics technology in the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements on power supply. With the widespread use of digital products such as mobile phones and notebook computers, lithium-ion batteries have been widely used in such products due to their excellent performance, and are gradually developing into other product application fields. Lithium-ion batteries have also entered a large-scale practical stage. The earliest application was lithium-sub-primary batteries, which were used in cardiac pacemakers. Due to the extremely low self-discharge rate of lithium sub-battery, the discharge voltage is very gentle. It makes it possible to implant the pacemaker int...
