How PPGlob test battery
PPGlob Battery Cell Reliability Test
| PPGlob Polymer Battery Cell Safety Test Criteria for Acceptance | |||
|---|---|---|---|
| Item | State | Test Method | Good Performance |
| External Short-circuit Test | Fully Charged | Cell tabs are short-circuited to discharged state less than 0.1V or longer time with a resistance of 50mΩ or less. Tests can be conducted at a room temperature. | No explosion, No fire |
| Heating Test | Fully Charged | The temperature of the oven is to be raised at a rate of 5±2℃/min to a temperature of 130±2℃, and remains for 30 minutes at this temperature. | No explosion, No fire |
| Crush Test | Fully Charged | Crush between two flat plates. Applied force is about 13kN. | No explosion, No fire |
| Impact Test | Fully Charged | Impact between bar (15.8mm diamter) and 9Kg falling material (at a height of 50cm). Bar is laid across the center of the test sample. | No explosion, No fire |
| Drop Test | Fully Charged | Drop a fully charged cell into a concrete floor from the height of 1 meter for 2 times. | No explosion, No fire |
| Vibration Test | Fully Charged | Vibrate the cell in tria-axial directions each for 90~100 mins, in conditions of 10~55Hz with amplitude 0.8mm. | No explostion, no deformation, no fire |
| Nail Test | Fully Charged | The battery is fully charged in standard charging condition, standby for 2 hours. A nail is penetrated vertically through the center of the cell. (The nail diameter is 3.0mm) | No explosion, No fire |
