Product Description
Aluminum Shell Case
As shown in the above explosion diagram, the main components of a typical prismatic lithium battery include: top cover, shell, positive plate, negative plate, laminated or winding composed of diaphragm, insulation parts, safety components, etc. Among them, two in the red circle are safety structures, NSD needling safety devices; OSD overcharge protection device.
Nail Safety Device (NSD). This is done by adding a metal layer, such as a copper sheet, to the outer part of the coil. When
needling occurs, the local large current generated at the needling position rapidly reduces the current per unit area through the large copper sheet, which can prevent local overheating at the needling position and slow down the occurrence of battery thermal runaway.
OSD (Overcharge Safety Device), currently this Safety design can be seen on many batteries. Normally it is usually a thin metal sheet and can be used together with fuse, which can be designed on the positive terminal fluid collector. When overcharged, the pressure generated inside the battery causes the OSD to trigger an internal short circuit and generate a large instantaneous current. Fuse is fused to cut off the current loop inside the battery.
The shell is usually steel or aluminum shell. With the market's pursuit of energy density and the progress of production
technology, aluminum shell has gradually become the mainstream.
