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".
