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.
Performance Curves of Lithium Cell:
