Abstract
The present disclosure provide a battery shell assembly and a lithium-ion battery. The battery shell assembly includes a shell, a pole and a connection terminal. The shell is formed with an accommodating cavity. The pole is disposed at the first end of the shell and is insulatively connected to the shell. The connection terminal is disposed on one side of the pole away from the shell. The connection terminal has a first welding portion and a second welding portion. The second welding portion is protrudingly disposed on one side of the first welding portion away from the pole. The first welding portion is electrically connected with the pole. The second welding portion is disposed to be electrically connected with an external circuit.
Claims19
A battery shell assembly, comprising:
- a shell formed with an accommodating cavity, the accommodating cavity being configured to place a core;
- the shell having a first end and a second end that are opposite to each other, and the first end being provided with an opening communicating with the accommodating cavity;
- a pole disposed at the first end of the shell, the pole being insulatively connected to the shell, and one side of the pole facing the accommodating cavity being disposed to be electrically connected with the core;
- and
- a connection terminal disposed on one side of the pole away from the shell, the connection terminal having a first welding portion and a second welding portion connected to each other, the second welding portion being protrudingly disposed on one side of the first welding portion away from the pole;
- the first welding portion being electrically connected with the pole, and the second welding portion being configured to be electrically connected with an external circuit;
- wherein one side of the first welding portion facing the pole has a first welding area, the first welding portion is disposed on an upper surface of the pole, and a height of an upper surface of the first welding portion is greater than a height of the first welding area and a height of the upper surface of the pole;
- and
- wherein the pole comprises a first connecting portion extending into the accommodating cavity, the battery shell assembly comprises a first insulating member, and a pressing block is disposed between the first insulating member and the first connecting portion, and the pressing block has a hardness greater than that of the pole.
A lithium-ion battery comprising:
- a battery shell assembly;
- and
- a core disposed within an accommodating cavity of the battery shell assembly, wherein the core has a first electrode electrically connected to a pole of the battery shell assembly, and a second electrode electrically connected to a shell of the battery shell assembly;
