Requirements


Crush


Fresh,

Fully charged


Crush between two flat plates. Applied force is about 13kN(1.72Mpa) for 30min.


No explosion,

No fire


Short

Circuit


Fresh,

Fully charged


Each test sample battery, in turn, is to be short-

circuited by connecting the (+) and (-) terminals of the battery with a Cu wire having a maximum resistance load of 0.1Ω.Tests are to be conducted at room temperature(20±2℃ ).


No explosion,

No fire The Temperature of the surface of the Cells are lower than 150℃

Prick through the sample battery with a nail having a diameter of 3mm and remain 2h.


No explosion,

No fire



Packing for Polymer Lithium-Ion Cell 4Ah 936060 3.7v For Big Capacity Power Bank

Due to avoid short circle, we pack the battery by specially plastic pallet

20pcs for one pallet and 8pallets for one standard paper carton.


The outer carton stick UN Lithium-ion label with international transportation rules



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.
