Manufacturing method of aluminum shell pin type bluetooth earphone battery

Abstract

The invention discloses a manufacturing method of an aluminum shell pin type bluetooth earphone battery. The manufacturing method comprises the following steps: S1, coating a conductive coating layer:coating conductive slurry on the surface of an aluminum foil, wherein the coating thickness is 1-3 microns; coating the conductive slurry on the surface of a copper foil, wherein the coating thickness is 1-3 microns; S2, coating: mixing a positive electrode active material, a binder, a conductive agent, a solvent, etc. into a positive electrode slurry, mixing a negative electrode active material,a binder, a conductive agent, a solvent, etc. into a negative electrode slurry, coating the positive electrode slurry on the aluminum foil coated with the conductive coating layer to be prepared intoa positive electrode sheet, and coating the negative electrode slurry on the copper foil coated with the conductive coating layer to be prepared into a negative electrode sheet; and S3, slicing: cutting the positive and negative electrode sheets, the negative electrode sheet and the diaphragm into specified dimension for use in the next process. The structural design is reasonable, the contact resistance is low, charging can be performed under the condition of 5G charging and discharging, the service life is long and the working voltage is 3.7 V.

Description

technical field [0001] The invention relates to the technical field of bluetooth earphone batteries, in particular to a manufacturing method of an aluminum shell pin-type bluetooth earphone battery. Background technique [0002] With the rapid development of the electronics industry, the battery is called the heart of electronic products. One of the most critical components of the Bluetooth headset is naturally the battery. In the eyes of ordinary consumers, the battery of this Bluetooth headset is the most important thing. The intuitive evaluation basis is the standby time, battery life and charging efficiency. It plays an increasingly important role in the development of the national economy and people's lives. As smart devices become more and more ubiquitous in life, the biggest problem that plagues users is still battery life. Or more precisely, limited battery capacity is one of the biggest bottlenecks in smart devices right now. However, as smart devices become thin...

Problems solved by technology

The characteristics of fast charging, the charging current is large, up to 100 mA, the original pin-type Bluetooth headset battery uses a pair of lead strips as the positive and negative output, which cannot withstand the long-term impact of large current, which is easy to cause internal heating, and the capacity is fast drop, product failure

The characteristic of slow charging is a long time, and these two characteristics are exactly what our original needle-type Bluetooth headset battery cannot bear, so we propose a manufacturing method for aluminum-shell needle-type Bluetooth headset batteries
