Lithium Battery Cell Model
Voltage of single cell of lithium battery is 3.7V, but Ni-MH and
Ni-Cd is only 1.2V, which means one lithium battery cell could
replace three Ni-MH or Ni-Cd cells. Therefore, lithium battery pack
has much smaller size than Ni-MH and Ni-Cd battery pack.
Self-discharge rate of lithium battery is 5% per month, which is
much lower than Ni-MH and Ni-Cd (25% per month). Lithium battery
has around 800 times of cycle life, which is also longer than Ni-MH
and Ni-Cd(500 times). So lithium battery is replacing Ni-MH and
Ni-Cd in more and more fields.
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
Conductive Coating of Lithium Battery
A conductive coating is called pre coating, in the Lithium Battery
industry usually coated on the surface of the anode current
collector foil, a layer of conductive coating, coated with a
conductive coating of aluminum foil is called pre coated aluminum
foil or aluminum foil coating, the first experiment in the battery
can be traced back to 70s, in recent years, with the new energy
industry. Especially the lithium iron phosphate battery development
fast, which becomes the hottest new technology and new materials.
The conductive coating can effectively increase the adhesion of the
polar plate, reduce the usage of the binder and improve the
electrical performance of the battery.
