At present, many electric bicycles have used lithium-ion batteries. The charge and discharge of the lithium-ion battery is a chemical reaction process. Under the calm surface, the lithium ions are running back and forth in the positive and negative poles.

When the lithium-ion battery is charged, the lithium atom of the positive electrode will lose electrons, oxidized to lithium ions, and lithium ions enter the negative electrode via the electrolyte, and obtain an electron, and reduce the lithium atom. When discharged, the process reverse. The flatulence, high temperature, explosion of the lithium-ion battery is usually related to overcharge, overlapping, and high currents, and the three will damage the battery.

When the excess charge occurs, the remaining number of lithium atoms in the positive electrode material is too small, causing the battery capacity to form a permanent drop. After the negative electrode, the lithium atom is saturated, the recharge will cause the lithium metal in the surface of the negative electrode material to form a dendrite crystallization. For a long time, the lithium branch crystal will wear the diaphragm and cause the positive and negative short circuit.

At the time of charge, the materials such as electrolyte tend to lysis of the gas, resulting in a battery case or pressure valve bumping, and the oxygen is stacked with a lithium atomic reaction on the surface of the negative electrode, resulting in an explosion. Similarly, the material will also cause damage to the material. Further, when the current is too large, the lithium ion is not asked inside the material, which will be concentrated on the surface of the material.

After the lithium ion obtains electrons, the lithium atomic crystallization occurs on the surface of the material. Since lithium is the most active metal, lithium atoms on the chemical cycle table Oxidation reaction with oxygen and exploding. When the fire related to the power lithium-ion battery occurs, people will always be associated with the quality of the dynamic lithium-ion battery, which is the maximum misunderstanding of the power lithium-ion battery.

The usage habit of power lithium-ion batteries, especially the charging process, which affects the dynamic lithium ion battery. Even if the quality is completely compliant with the power lithium-ion battery of the national standard, it is also unable to operate the user's violation. This time, the use of fires in Chaoyang District, the dynamic lithium-ion battery, sounded the alarm, and the heart is often caused by a big disaster.

The fire department reminds: electric vehicles generally use during the day, parking at night, 6 to 8 hours in the charging time, the user is inserted at night, 9 o'clock in the evening, two in the morning, three points are essential, if you continue to charge, Battery, charger will be charged, fever, may cause fire. At this time, people are generally asleep, and it is difficult to find and save in time. Further, when the current is too large, the lithium ion is not asked inside the material, which will be concentrated on the surface of the material.

The usage habit of power lithium-ion batteries, especially the charging process, which affects the dynamic lithium ion battery. Even the quality of the quality is fully compliant with the national standard power battery, and it is also unable to operate the user's illegal operation. This time, the use of fires in Chaoyang District, the dynamic lithium-ion battery, sounded the alarm, and the heart is often caused by a big disaster.
