Condition

 

Test Method

 

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℃

Impact

 

Fresh,

Fully charged

 

A 56mm diameter bar is inlayed into the bottom of a 10kg weight. And the weight is to be dropped from a height of 1m onto a sample battery and then the bar will be across the center of the sample.

No explosion,

No fire

 

Forced

Discharge

 

Fresh,

Fully charged

 

Discharge at a current of 1 C5A for 2.5h.

 

No explosion,

No fire

 

Nail

Pricking

 

Fresh,

Fully charged

 

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 batteryby specially plastic palltet

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

 

The outer carton stick UN Lithium-ion label with internation 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.
