Safety Test Method And Standard
Due to more stringent regulations in dealing with dangerous goods, Tac make the safe test follow UN38.3
and submit the MSDS UN38.3 when the cargo shipped out for most LP battery
Item | Battery 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℃ |
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 temperature(60±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 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.
