The short -circuit of batteries is divided into external short circuits and internal short circuits. The external short -circuit generally refers to the short circuit caused by the direct contact of the positive and negative electrode; the internal short -circuit refers to the short circuit of the battery in the area of the foreign object when the battery is punctured or collided and squeezed by the sharp object.
External short -circuit security analysis
External short -circuit security studies are tested by direct connection of positive and negative poles on the outside. Li Yi and others conducted a short -circuit of the battery. They will study the lithium cobalt -type lithium -type lithium -ion battery, 6 -core laptop battery (6 18650 batteries, 3 series in one group, 2 groups, remove the protection circuit) The positive and negative pole uses a wire short circuit, and the thermocouple is pasted on the surface of the battery to detect changes in the surface temperature of the battery.
Internal short -circuit security analysis
Short -circuit security studies inside the battery generally use acupuncture, extrusion and other methods to test. The purpose is to simulate the battery's puncture, collision, and squeezing of the battery. Acupuncture caused the battery to short -circuit at the acupuncture point. The short -circuit area formed a local hot zone due to a large amount of scorched ear heat. When the temperature of the hot area exceeds the critical point, it will cause heat loss, and the danger of smoking, fire and even explosion. Squeeze is similar to acupuncture, which causes short circuit in the local area and may cause heat out of control. The difference is that squeezing does not necessarily cause damage to the battery shell. If the shell does not damage, it means that the flammable electrolyte will not leak from the hot area. The heat dissipation effect at the hot area is worse.
Tests that cause short -circuit internal internal internal internal internal internal circuit through squeezing and acupuncture are often more rare than passing the short -circuit testing outside the battery. This is because the battery is often uniformly put on the battery in the external short -circuit of the battery. Directly touched the thermal discharge of the battery.
Test conditions such as acupuncture and extrusion have a greater impact on the test results. This is because the internal short circuit conditions caused by acupuncture and extrusion tests under different conditions are different. Impact. There are 4 types of short -circuit in the battery: (1) between the album and the negative electrode material (LIC6, C6); (2) between 4) Between the positive material and the CU set.
By analyzing thermal stability of lithium -ion battery negative materials, positive poles and electrolytes, the main factors affecting the thermal stability of lithium -ion batteries are summarized. Sexual analysis is analyzed in detail, providing a reference for the safe use of lithium ion batteries. When more people pay attention to the danger of the lithium ion battery itself, and at the same time, the safety management of lithium ion electronics production, storage and use of lithium ion electronics will greatly reduce the lithium -ion battery fire.
