[0002] Rechargeable batteries bring convenience to people with their rechargeable characteristics. They not only solve the pollution caused by disposable batteries to the environment, but also greatly reduce the cost of use.

[0003] Existing rechargeable batteries generally include an upper cover and an outer shell that are closed to each other, and a battery cell is installed in the enclosed space between the upper cover and the outer shell, and a positive electrode cap is installed on the upper cover. An integrated circuit board that is conductively connected to the battery cell and the positive electrode cap is also included in the enclosed space between the upper cover and the outer shell. The integrated circuit board is provided with a positive electrode spring that is conductively connected to the positive electrode of the battery cell and a negative electrode spring that is conductively connected to the outer shell. The positive electrode spring is conductively connected to the positive electrode cap of the integrated circuit board through the integrated circuit board.

[0004] However, the positive and negative electrode springs are easily degraded after prolonged contact with the battery core and the outer shell, leading to poor contact and failure of the rechargeable battery. Utility Model Content

[0006] To achieve the above objectives, the present invention provides a novel battery, comprising a positive electrode cap, an upper cover, an integrated circuit board, a battery cell, and a negative electrode shell, wherein the positive electrode cap is mounted on the upper cover, and a pin of the positive electrode cap is conductively connected to the positive electrode of the integrated circuit board. The battery cell is mounted in a receiving space of the negative electrode shell, and the negative electrode of the battery cell is conductively connected to the negative electrode shell. The upper cover is mounted on the negative electrode shell, and the integrated circuit board is located between the upper cover and the battery cell. The integrated circuit board comprises a first terminal conductively connected to the positive electrode of the integrated circuit board and a second terminal conductively connected to the negative electrode of the integrated circuit board.

The insulating sheet is provided with an opening therethrough, and the first abutting portion of the first terminal passes through the opening and abuts against the positive electrode of the battery cell.

[0008] Further, the first elastic portion is formed by arcuately bending and extending from one end of the first welding portion and is suspended above the first welding portion, and the first abutting portion is formed by arcuately bending and extending upward from the end of the first elastic portion.

[0009] Further, a solder blocking groove that arcuately bends and extends upward is provided between the first welding portion and the first elastic portion.

[0010] Further, first side plates extend vertically upward on both sides of the first welding portion, and at least one upper end edge of the first side plates extends horizontally toward the other first side plate to form a first limiting plate. The first welding portion, the first side plates and the first limiting plate jointly enclose a first space, and at least a part of the first elastic portion is located in the first space.

[0011] Further, the second elastic portion is formed by arcuately bending and extending from one end of the second welding portion, and the second abutting portion is formed by arcuately bending and extending outward from the end of the second elastic portion.
