Product performance:
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.
1. High working voltage for single battery cells
2. Pollution-free
3. Long cycle life
4. No memory effect
5. PCM inside with short-circuit protection
function,over-discharge, over charge, over current protection
6. Good consistency, low self discharge
7. Light weight, small and customized size
8. Wide application for electronics and industry
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.
Application :
Lighting, backup power supply, wind energy storage, communication
equipment, IT products, IC card terminal, GPS system, LED lights,
medical equipment,instrumentation, beauty and hair products,
electric toys, flashlight, miner's lamp, agricultural machinery
equipment, electric tools, 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.
Handling of tabs
The battery tabs are not so stubborn especially for aluminum tab.
Don’t bend tab.
Do not bend tabs unnecessarily.
