About the safe use of lithium batteries

    Before we use lithium power as a source of power, there are many things that we should understand. Nothing is more important than security. We should treat them carefully regardless of the type of battery, because they are full of energy when they are fully charged.
Lithium batteries have the highest energy density, and they also have many unique characteristics that require us to make more special safety considerations. It is very important to understand these safety issues before beginning to explore other aspects of lithium batteries.
In general, if the lithium battery charger can correctly calculate the composition of the lithium batteryCellThe number (referring to a large lithium battery is composed of several single small lithium batteries), can be adapted to lithium-ion batteries (Li-ion) and polymer lithium battery (Li-Poly) the need for charging. Remember not to use nickel and cadmium (Ni-Cd) with nickel hydrogen (Ni-MHThe battery charger to charge the lithium battery! That is a very dangerous thing! ! !Charging the lithium battery is the most dangerous part when using lithium battery. When charging the lithium battery, please pay attention to the charging status of the lithium battery. The correct charging voltage is very important! If the charger is used improperly, it may cause overcharge of the lithium battery and cause an explosion! Recently, the news reported that several fires were caused by lithium batteries, so please charge the lithium battery in a responsible manner.
The following are some guidelines for charging and using lithium batteries:
1Use a lithium-ion battery charger that has been proven to be safe to use.
2Make sure that you have correctly set the voltage on the lithium battery charger or the number of batteries. If you don't know how to set it, please buy a lithium battery charger that you know how to set, otherwise it is Do not use lithium batteries to avoid an explosion when charging.
3When charging lithium batteries, someone must be present. Don't charge the lithium battery when no one is present. Someone used to burn the house and the car for this reason. Remember to remember.
4When charging, please prepare a suitable platform to place your charger and lithium battery to ensure that the lithium battery will not cause serious damage and danger due to accidental explosion or fire. It is necessary to reserve fire prevention space and do a good job in fire protection.
5Please do not charge with current exceeding the battery's capacity, otherwise explosions and fires are most likely to occur.
6If the lithium battery expands during charging, don't break it when it is still hot. Put the lithium battery in the brine, after cooling, carefully peel off the skin and then put the battery back into the brine before you can safely throw the problematic lithium into the trash.
7When the lithium battery is severely impacted, the battery may not appear damaged, but it is still necessary to carefully place the lithium battery in a safe place.20More than a minute to ensure that the lithium battery is really not damaged and there is no explosion. In the aircraft model world, there are several fire cases. After the lithium-powered aircraft crashed, the owner dropped the corpse in the car, and then the lithium battery that appeared to be damaged but actually damaged inside exploded in the car. Burn the entire car.
8Please charge the lithium battery in an open and ventilated place, because if the lithium battery really ruptures and explodes, dangerous and harmful smoke and substances will leak out of the battery.
9Please fully understand the dangers of lithium batteries. Don't have the idea that "I won't be so bad, this won't happen to me." Otherwise, the next person who saves his wife and children in a burning house or car is you. I attach great importance to this.
