Abstract

The invention discloses a flashlight battery. A support is fixedly connected to an electric top end, a positive electrode nickel sheet is fixedly connected with the positive electrode of a battery cell and is positioned in the support, and a protection plate is fixedly connected in the support and is positioned at the top end of the positive electrode of the battery cell. One surface of a negativeelectrode steel cap is in spot welding connection with the protection plate, and the other surface of the cathode steel cap is in spot welding connection with the cathode of the battery cell. A negative electrode bottom sheet is connected with the negative electrode of the battery cell in a spot welding manner and is positioned at the bottom end of the battery cell, and a sleeve sleeves the outersurface wall of the battery cell. By adopting a battery anode protection scheme to replace a battery cathode protection scheme, the cathode of the battery cell is directly connected with the protection plate and the cathode of the battery cell through the cathode steel cap in the spot welding manner, and the bottom of the battery cell only needs to be subjected to spot welding with the cathode negative film, so that the purposes of reasonable and compact structural design and simple and smooth production process are fulfilled.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a flashlight battery. Background technique [0002] With the development of society and the improvement of people's living standards, flashlights have become a necessary small household appliance for every household. Lithium batteries have various advantages such as small size, light weight, high specific energy, environmental protection and no pollution. Its application has penetrated into many fields. The use of lithium batteries in the flashlight industry has become very common. [0003] At present, due to structural limitations, many lithium flashlight batteries are designed as a negative electrode protection scheme. Therefore, spot welding of nickel sheets is required from the negative electrode to the positive electrode, and a second spot welding of the positive electrode steel cap is required. Due to the complicated production process, the production efficiency i...
