Product performance:
1.The working voltage of single cell is as high as 3.6-3.8v.
2.Greater than the energy. At present, the actual specific energy
of hyb steel shell battery is 100-135w.h/kg & 280-353w.h/l (2 times
of Ni Cd and 1.5 times of Ni MH). With the development of
technology, the specific energy can reach as high as150 w.h/kg and
400 & w.h/l.
3.Long service life. The service life of 18650 lithium battery is
very long. The cycle life of 18650 lithium battery is more than 500
times, which is more than twice that of ordinary battery.
4.Good safety performance, no pollution, no memory effect. As the
predecessor of Li ion, Li ion battery has short circuit due to its
easy formation of dendrite lithium, which shortens its application
fieldThere are some pollution elements in the environment. One of
the disadvantages of some Ni Cd batteries is "memory effect", which
seriously restricts the use of batteries, but there is no such
problem in Li ion.
5.Large capacity. The capacity of 18650 lithium batteries is
generally between 1200mAh and 3600mAh, while the capacity of
general batteries is only about 800. If 18650 lithium batteries are
combined to form 18650 lithium batteries, then 18650 lithium
batteries will be used Group a can break through 5000 MAH at will.
Application:
1. Toys
2. Smoke alarm
3. Electric scales
4. Electric toothbrush
5. Wireless doorbell
6. Remote controller
7. Electronic instrument
8. Electronic thermometer
9. Cordless telephone/Microphone etc.
Performance Curves of Lithium Cell:
1.Lithium Cell Charge Curve (Charge at 1C)
2. Lithium Cell Discharge Curve (Discharge at 1C )
3. Lithium Cell Cycle Life Curve
What is the Equalization Treatment of Lithium Battery Packs?
Lithium battery packs are made up of multiple batteries. Since the
batteries are independent individuals, there will be some slight
differences. After the combination is welded, it will be affected
by the direction and length of the connecting piece and the welding
process. Increasing the generation of differences, each charge and
discharge will increase the value of individual differences. When
the value reaches a certain height, it will eventually lead to
partial overcharge and overdischarge of the cell. This situation
will cause damage to the cell and ultimately As a result, the
entire set of lithium batteries cannot work effectively.
The equalization treatment of lithium battery pack can solve this
problem. When there is a large difference in the value of a single
string of lithium-ion batteries, the equalization voltage of the
battery is controlled by the BMS, which can maximize the service
life of the lithium battery pack. To put it bluntly, the balance is
to maintain all lithium battery packs in all normal categories to
ensure overall safety.
The balance link is to ensure that the input and output of the
lithium battery pack are reasonable to each lithium battery, so
that they can be used reasonably and effectively without damage. At
present, the two most common equalization methods for lithium
battery packs are energy-consumption equalization and
transfer-energy equalization.
Lithium battery equalization technology means that after the
lithium batteries are grouped, the overall performance of all
batteries in the battery pack is brought to the same level through
human intervention. The purpose is to ensure that the performance
of the lithium battery pack can be fully utilized and to ensure the
safety of the battery during use.
