LiFePO4 Prismatic Cells Description:

Square lithium battery structure
The main components of a typical square lithium battery include: top cover, housing, positive plate, negative plate, laminating or winding separator, insulation, safety components, etc. Among them, two in the red circle are safety structures, NSD acupuncture safety device; OSD overcharge protection device.

NSD, Nail Safety Device, adds a metal layer, such as a copper sheet, to the outside of the jelly-roll. When acupuncture, the local large current generated at the acupuncture site rapidly reduce the current per unit area through the large-area copper sheet, which can prevent local overheating at the acupuncture site and prevent battery thermal runaway.

The OSD (Overcharge Safety Device) is a safety design that can be found on many batteries. Generally, it is a metal sheet, which can be used with fuse. The fuse can be designed on positive collector. The pressure generated in the battery during overcharging causes the OSD to trigger an internal short circuit, generating an instant large current, which fuses the fuse and cuts off the internal current circuit of the battery.

Square lithium iron phosphate battery is usually referred to aluminum or steel shell square battery. Domestic power battery manufacturers mostly use aluminum shell square battery with high battery energy density, because the structure of the square battery is relatively simple. Otherwise, cylindrical battery has stainless steel with high strength as the shell and accessories with explosion-proof safety valve. The overall accessories should have light weight and relatively high energy density. The square cell has two different processes: winding and laminating.

Super long service life -- The battery pack has a long cycle life, which can reach more than 2000 cycles.

Low cost -- The comprehensive cost is lower than lead-acid battery and lithium manganate battery.

Reliable safety -- Lithium iron phosphate has stable structure and reliable safety, which is different from other lithium ion batteries. There will be no explosion or combustion in the event of impact, heavy load, puncture, short circuit, overcharge, overheating and other extreme conditions.

Excellent temperature adaptability -- Lithium iron phosphate battery has stable structure, excellent high temperature performance and good low temperature performance. It has stable performance and small capacity attenuation during storage and transportation.

Environmental friendly - Lithium iron phosphate batteries do not contain mercury, cadmium, lead and other harmful elements. It is known as the "new generation of green power".
