Can a soft bag polymer lithium ion battery burns explosion? In general, soft bag polymer lithium ion battery explosion is rarely burned because of external circuitry, which means the vast majority of lithium-ion battery explosion combustion events, and is from the design defect inside the battery. Today, the lithium-ion polymer battery has been promoted today, the most important thing to do with big lithium-ion battery manufacturers is undoubtedly the control of battery safety. Can a soft bag polymer lithium ion battery burns explosion? The soft bag polymer lithium ion battery has a variety of energy densities, smaller, ultra-thin, lightweight, and high safety, etc.
, is a new battery. In shape, the lithium polymer battery has ultra-thin characteristics, which can be used in combination with various products, making batteries of any shape and capacity. The minimum thickness of this type of battery can reach 0.
5mm, no memory effect. The soft bag polymer lithium ion battery is a lithium ion battery product made of soft packaging and polymer electrolyte. Under normal circumstances, storage will not explode, unless people are strong destruction leads to short circuits.
The current polymer lithium ion battery is mostly a soft bag battery, which is made of an aluminum-plastic film. When the organic electrolyte is used inside, even if the liquid is hot, it does not explode, because the aluminum-plastic film polymer battery uses a solid or colloidal state without leakage Liquid, just naturally broken. But anything is not absolute.
If the instant current is large enough, short circuits have occurred, and the battery spare or burst is not impossible, and the occurrence of mobile phones and tablet safety accidents caused by this situation. In order to reduce the occurrence of the explosion, the polymer lithium ion battery is increasing, although the lithium ion battery is still in the process, but in the lithium ion battery type, the polymer lithium ion battery has begun. In some category replacing a general lithium ion battery.
The conditions of the polymer lithium ion battery exploded combustion combustion, the soft boiled lithium-ion battery is severely overchaled, the chemical system of the lithium ion battery determines that the LicoO2 inside the battery core becomes CO3O4 after the battery cell is overcharged, CO3O4 is very Strong oxidant, can be reactive with electrolyte (O2). When the electrical core voltage reaches 5V, with the increase of the temperature of the cell and the gas pressure is used, most of the cells will burn or explode due to internal short circuits. 2, the battery is heated by high temperature, when the battery is heated by high temperature, the electrolyte will vaporize while analyzing, the internal pressure of the battery is increased, the isolation film inside the battery can be melted to cause a short circuit inside the battery, and the cathode When the material is overflowing, at a certain temperature, a self-catalytic reaction occurs, a combustion occurs.
3, the battery is short-circuited, the battery is overcharged, and it is suddenly short-circuited. This is likely to cause safety accidents in the battery. Handling problems for the above aspects, currently adopting a protective board, PTC, special charger, and fuses, etc.
Among them, the protective plate is the overcharge of the battery, and the excessive overcurrent is protected. The PTC is the cut-off current for the secondary protection when the battery is too hot, and the dedicated charger is The charging current and voltage of the battery are limited, and the fuse currently uses less use, and its important use is to completely cut off the connection of the battery and the external circuit when the battery voltage or current is abnormal, thereby ensuring that the battery is not used again. To ensure that the battery does not have a serious safety accident.
How to prevent polymer lithium ion battery explosions? All lithium ion battery explosions are caused by fever caused by short-circuited batteries, but caused by short-circuit, over-depth, positive and negative poles direct docking, electrolyte leaks, etc. Therefore, in the lithium ion battery design, it can be started from the following: 1. The battery is prohibited from over 4.
2V; 2. Prohibiting the battery over 2.75V; During the process, anti-short circuit.
The best way is of course designed to have a lithium-ion battery protection circuit board. Although it will add a lithium-ion battery manufacturing cost, but the safety use of lithium-ion batteries is necessary, all regular lithium-ion batteries plus the manufacturer's products are inevitably. Polymer Lithium Ion Battery Correct Charge Meption 1 Slow, while at a high temperature, the battery will be unstable, even caused explosion! 2, the number of charging pays attention to "less food" has a statement: each mobile phone battery has a fixed number of charge, if there is too much charging, it will speed up the capacity of the battery aging! In fact, this is wrong, the polymer lithium-ion battery is the same, paying attention to less food, frequent charging is actually a slight advantage for the battery! 3, should the new battery are activated? The batteries in the past have to be done, but today's polymer lithium-ion batteries are not! 4, charging should not be too long to charge, don't make anything wrong for 12 hours, charging as long as it is the same as usual charging! Regarding consumers, choose a reliable soft bag polymer lithium-ion battery, and use a lithium-ion battery correctly in an appropriate environment, it is the key to alert accident.
Soft bag polymer lithium ion battery has become an important power supply of portable electronic products such as mobile communications, laptops, etc.
