Lithium-ion batteries have been widely used in people's daily lives, so its safety performance should definitely be the first indicator of lithium-ion batteries. For the safety performance evaluation indicators of lithium-ion batteries, very strict standards have been set internationally. A qualified lithium-ion battery should meet the following conditions in terms of safety performance:
1) Short circuit: no fire, no explosion;
2) Overcharge: no fire, no explosion;
3) Hot box test: no fire, no explosion (150 ° C constant temperature 10 min);
4) Acupuncture: no explosion (penetrate the battery with Φ3mm nail);
5) Flat impact: no fire, no explosion; (10kg weight from 1 meter high to the battery);
6) Incineration: Do not explode (gas flame burn test battery).
In order to ensure the safe and reliable use of lithium-ion batteries, experts have carried out a very strict and thorough battery safety design to achieve battery safety assessment indicators.
1.Diaphragm 135 °C automatic shutdown protection: the international advanced Celgard 2300PE-PP-PE three-layer composite film. When the battery temperature rises to 120 ° C, the PE film holes on both sides of the composite film are closed, the internal resistance of the battery is increased, and a large area of the battery is broken inside the battery, and the battery is no longer heated.
3. Battery cover composite structure: The battery cover adopts a scoring explosion-proof structure. When the battery heats up, the pressure reaches a certain degree and the nick is broken and deflated.
4, a variety of environmental abuse tests: conduct various abuse tests, such as external short circuit, overcharge, acupuncture, plate impact, incineration, etc., to examine the safety performance of the battery. At the same time, the battery is subjected to temperature shock test and mechanical tests such as vibration, drop and impact, and the performance of the battery under actual use environment is investigated.
Battery explosion causes:
1: Internal polarization is large.
2: The pole piece absorbs water and reacts with the electrolyte.
3: The quality of the electrolyte itself, performance problems.
4: The amount of liquid injection during the injection is not up to the process requirements.
5: Laser welding and welding performance in the assembly process is poor, leaking, leaking when measuring leaks.
6: Dust, extreme dust is easy to cause micro short circuit.
7: The positive and negative electrodes are thicker than the process range, and it is difficult to enter the shell.
8: Injecting and sealing problems, the steel ball sealing performance is not good, resulting in air drum.
9: The shell material has a thick shell wall, and the shell deformation affects the thickness.
