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.
Application :
Mobile phones, tablets, Bluetooth earphone, smart watches and other smart wearable devices, GPS, electric toys, beauty instruments, aromatherapy machines, LED lights, quad copters, drones ,etc.
Handling of Cells
Consideration of strength of film package
Soft Aluminium foil
Easily damaged by sharp edge parts such as pins and needles, Ni-tabs, comparing with metal-
can-cased LIB.
Sealed edge may be damaged by heat above 100°C, bend or fold sealed edge.
Prohibition short circuit
Never make short circuit cell. It generates very high current which causes heating of the cells
and may cause electrolyte leakage, gassing or explosion that are very dangerous.
The LIP tabs may be easily short-circuited by putting them on conductive surface.
Such outer short circuit may lead to heat generation and damage of the cell.
An appropriate circuitry with PCM shall be employed to protect accidental short circuit of the
battery pack.
Mechanical shock
LIP cells have less mechanical endurance than metal-can-cased LIB.
Falling, hitting, bending, etc. may cause degradation of LIP characteristics.
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
