How do lithium-ion batteries happen to use lithium-ion batteries? Lithium-ion battery short circuit is due to direct contact of the positive and negative bipolar, the lithium ion battery must be recognized in addition to the manufacturer must recognize and prevent the safety risks that the use of lithium ion batteries may also be responsible for the lithium-ion battery. Danger, understand how to use it safely, so only everyone has a safe consensus to reduce the injury caused by the occurrence of lithium-ion batteries. The cause (1) of a lithium-ion battery short circuit occurs (1) positive material is not pure or in the air, the drying is not thorough; the transition metal impurities in the positive electrode slurry will result in piercing the diaphragm or promote the negative electrode lithium delegated crystal.

Generation results in internal short circuits; (2) short circuits between copper / aluminum aggregates, battery production or non-trimming metal foreign matter puncture diaphragm or electrodes, battery packs, or extreme ear displacement cause positive, negative set fluid Caused by contact; (3) The quality of the lithium core membrane does not meet the standard, and the lithium-ion battery pack is often high in the use process, and the diaphragm is undergoing a large-scale lithium ion stream through a short period of time. Directly lead to dramatic heat, damage; (4) Lithium-ion battery during cycle use, low or longevity of the negative electrode material is low, and the lithium ion breaks from the positive electrode, free too much Lithium ions, in a long time, a dendrite crystallization is formed, and the dendrite is long to have a certain length. It is easy to pierce the diaphragm caused the battery.

Low temperature also helps the growth of lithium dendrites, so low temperatures will also cause micro-short circuits of lithium-ion batteries. How to use lithium ion batteries safer? 1. Do not contact the positive and negative electrode portion of the lithium ion battery in use to contact the metal item, which is also far from the metal item and high temperature, so as to avoid short circuit of the lithium-ion battery.

2, the lithium ion battery should be stored in a low temperature and dry environment when not in use, and should not be placed in direct sunlight from the heat source; it is generally considered to be filled with a temperature of about 40% at a temperature of 10 to 30 degrees Celsius. And make up the electricity every half a year. 3, before the charging and discharging of lithium battery is recommended to detect how much the battery per piece of the battery is; the battery voltage in the factory is about 3.

8V, the maximum limit voltage of the battery is 4.25V, minimum voltage 2.75V, when the battery voltage is higher than 4.

25V or less than 2.75V, the charge and discharge performance and safety performance of the battery may result in heat generation, leakage, and flatulence. 4, the lithium ion battery is different from nickel-chromium and nickel-hydrogen batteries because it has a very bad "aging" characteristic, that is, even if it is stored for a while, it will be lost, and the lithium-ion battery should be permanently lost.

After filled with re-stored capacity loss, "aging" is different in different temperatures and different power states. 5, the charging process should not be charged or over, we often like to charge the power of the equipment and then charge for a while, so that your equipment can resist more time. Long-term overchaling and overplay will seriously damage and destroy the performance of lithium ion batteries, which will cause extreme conditions such as explosions, so the electricity of lithium-ion batteries is full.

To usually we should pay special attention to the use of lithium-ion batteries, the equipment that can be replaced battery is used to use the original battery. When charging, it should be kept through the wind, especially if the phone is best not placed on the bed, so as to avoid heat generation, the battery explosion. In the future, the lithium-ion battery is still mainstream, and the security of the strengthening the battery is also the direction of most manufacturers.

I believe that the lithium-ion battery has become more secure in soon.
