How to avoid fire accidents or explosions of rechargeable batteries that cannot be controlled by heat?
Safe to use! What looks like a battery is actually a bomb.
Lithium battery is a graphite negative electrode, non-aqueous electrolyte solution battery.
Most mobile phone batteries and electric cars are lithium batteries. Lithium battery, a high-energy lithium battery that causes heat and heat loss inside the lithium battery in the event of an accidental short circuit (high temperature, overload, list, etc.), which can cause the battery temperature to rise further, accelerate side reactions, and release more heat. Cause the temperature to rise, further reaction process, release more heat, and eventually cause the battery to lose control.
The reasons for the explosion of lithium batteries are: baking, high temperature, external short circuit, squeeze impact, overcharge, overdischarge, soaking, etc.
What looks like a battery is actually a bomb…
June 11, 2019, Dali, Yunnan Province
On June 11, a lithium battery caught fire while charging at the Tourist Information Service Center in Dali, Yunnan Province. The fire covered an area of 230 square meters and caused 6 deaths.
Ne quid est?
1. Buy reliable products
First of all, the battery must choose the product of the regular manufacturer, friends do not pay for the quality of the battery itself!
2. Cave
Try not to knock or pierce with sharp tools to prevent high temperature and low temperature from happening together. If the battery is damaged or inflated, do not use it again.
The discharge function of lithium battery greatly reduces the winter, when its internal crystallization temperature is low, the charge may pierce the separator, so it is recommended to use lithium batteries in winter to do a good job in battery insulation, and return to room temperature before charging.
3. External fuel charging
Although qualified lithium batteries are not so risky, people should still use batteries with caution. Try to observe when charging, charge as soon as possible after charging, and keep the battery away from fuel when charging.
