1. What is a cylindrical lithium battery?
Cylindrical lithium batteries
are divided into different systems such as lithium iron phosphate,
lithium cobalt oxide, lithium manganate, cobalt-manganese hybrid, and
ternary materials. The outer shell is divided into two types: steel
shell and polymer. Different material systems have different advantages.
At present, steel cylinders are mainly steel-shell cylindrical lithium
iron phosphate batteries, which have the characteristics of high
capacity, high output voltage, good charge-discharge cycle performance,
stable output voltage, large discharge current, stable electrochemical
performance, safe use, and wide operating range. temperature range.
Environmental protection, widely used in solar lights, lawn lights,
back-up energy, power tools, toy models.
2. Cylindrical battery structure
The
structure of a typical cylindrical battery includes: a case, a cap, a
positive electrode, a negative electrode, a separator, an electrolyte, a
PTC element, a gasket, a safety valve, and so on. Generally, the
battery case is the negative electrode of the battery, and the cap is
the negative electrode of the battery. The positive electrode of the
battery, and the battery case is made of nickel-plated steel plate.
3. the advantages of cylindrical lithium batteries
Compared with soft-packed lithium batteries
and square lithium batteries, cylindrical lithium batteries have the
longest development time, with a higher degree of standardization, a
more mature process, a high yield and a low cost.
1. Mature production technology, low PACK cost, high battery product yield, and good heat dissipation performance
2.
Cylindrical batteries have formed a series of internationally unified
standard specifications and models with mature technology and suitable
for continuous mass production.
3. The cylinder has a large specific surface area and a good heat dissipation effect.
4. Cylindrical batteries are generally sealed batteries, and there are no maintenance problems during use.
5.
The battery shell has a high pressure resistance, and there will be no
phenomena such as square, flexible packaging battery expansion during
use.
