Security is the foundation for higher performance. we secure the heart of power
you need. Tianneng Group offers high-quality lithium ion battery cells for sale
at great prices.

APPLY BOTH NCM AND LFP TECHNOLOGY
Tianneng Battery produces both cylindrical and pouch cell with NCM and LFP
technology. From material research to cell production, Tianneng Battery takes
every step with strict simulation and configuration to secure the heart of the
power you needed. Security is the foundation for Tianneng Battery's li-ion cell
performance. Above that, the best lithium ion cells boasts other excellent
performance, like high energy density, long cycle life, outstanding high and
low-temperature performance, great consistency, etc. In particular, the NCM
cells are highly suited for electric vehicles, with a high energy density of up
to 200Wh/kg and a long lifespan of a maximum of 1500 cycles@100%DOD. The LFP
cells are capable of reach 10C continuous discharge current, which is a perfect
match for UPS, telecom and energy storage applications. Besides battery
performance, Tianneng Battery has a 5GWh production capacity for power lithium
battery, which means at least 1 million cells can be produced every day, and
after we cooperated with SAFT, a company of total, the production will continue
to expand up to 18GWh to ensure stable delivery for global customers.

How To Charge Lithium Cell?
With the development of science and technology, now lithium-ion batteries have
gradually become the mainstream in the industry. But what is the correct way to
charge a lithium-ion battery cell?

The charging for new Li-ion cells

As the lithium cell will enter the hibernation state if it is not used for a
long time, the capacity of the battery will be lower than the normal value
under this circumstance, and the use time of the cell will also be shortened.
Therefore, it is necessary to activate the lithium-ion battery cells before the
first use. The activation method of a lithium-ion rechargeable battery cell is
very simple. The 3-5 times of normal charge and discharge process can activate
the cell and restore its normal capacity.

The recharging of li ion coin cell
The life of a lithium ion rechargeable battery cell is independent of the
number of charges and discharges. It has no memory effects. That is to say, no
matter how you charge the lithium-ion rechargeable cell, it will not affect the
number of charge cycles. The safe operating voltage range of lithium cell
batteries is 2.8 to 4.2V. Below or above this voltage range, the lithium ions
in the cell will become unstable. Thus, to ensure that the lithium-ion
rechargeable cell is working in a safe range, it is better to use the special
chargers specifically designed for the lithium power cells. The chargers for
rechargeable lithium cells can automatically adjust the charging mode based on
the current state of the battery. And as for the lithium cell batteries that
are not used for a long time, they should be stored in a cool and dry place in
a semi-electric state. If the battery is stored with a full charge, it will be
damaged. If the lithium battery cells for sale are stored without power, they
may get destroyed and lose their basic function. During the storage process, it
is better to complete a charging cycle every 3 to 6 months, so as to further
conduct a power calibration.
