Integrally-formed rechargeable battery and production method thereof

Abstract

The invention discloses an integrally-formed rechargeable battery and a production method thereof, and the lithium battery comprises an integrally-formed metal sleeve which serves as the anode conductor of the lithium battery; the integrally-formed metal sleeve is a columnar shell, the end face of one side of the integrally-formed metal sleeve is of a closed structure, and the end face of the other side of the integrally-formed metal sleeve is an annular part with a middle hole. A battery cell assembly is arranged in the integrally-formed metal sleeve and is provided with a battery cell, a circuit board, an exposed charging interface and an exposed positive electrode conductor; a cathode conductor is exposed from the middle opening of the annular part. The invention relates to the integrally-formed rechargeable battery and the production method thereof. The battery cell assembly is surrounded in the integrally-formed metal sleeve which is integrally formed and provided with the end faces at the two ends, so that the appearance is smooth, the overall structure of the lithium battery is reliable, the battery cell assembly cannot be loosened, no burrs exist at the two ends of the metal sleeve, and the outer film of the battery cannot be damaged or a user cannot be scratched.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an integrally formed rechargeable battery and a production method. Background technique [0002] Batteries are commonly used items in daily life, such as remote controls, toy cars, etc. Batteries are often used. Most of the existing batteries are disposable batteries, and they are thrown away when the power is used up. High-grade batteries are easy to pollute the environment, so rechargeable batteries have appeared. Due to their rechargeable characteristics, they can be recharged after the power is used up, which can greatly save the cost of using batteries. The structure of the existing rechargeable batteries is not reliable and reasonable. Generally, the existing rechargeable batteries place the charging circuit board on the positive pole of the battery. Two nickel strips need to be connected to the positive and negative poles of the battery cell, and the battery cell needs t...

[0002] Batteries are commonly used items in daily life, such as remote controls, toy cars, etc. Batteries are often used. Most of the existing batteries are disposable batteries, and they are thrown away when the power is used up. The battery is easy to pollute the environment, so there is a rechargeable battery. Due to its rechargeable characteristics, it can be recharged after the power is used up, which can greatly save the cost of using the battery.

The structure of the existing rechargeable batteries is not reliable and reasonable. Generally, the existing rechargeable batteries place the charging circuit board on the positive pole of the battery. Two nickel strips need to be connected to the positive and negative poles of the battery cell, and the battery cell needs to be repaired. The head is cut off, and the whole battery is wrapped with a tubular steel sleeve. This structure uses a nickel strip to connect with the risk of desoldering, and the sleeve of the steel sleeve has a sharp edge that is easy to damage the outer membrane of the battery. uneven marks
