Lithium Battery Knowledge

Will Li-ion batteries explode if they are overcharged? Speaking of battery explosion, the first thing that comes to mind is the explosion of lithium-ion batteries. Many people think that lead-acid batteries will not explode. Compared with lithium-ion batteries, lead-acid batteries are slightly safer, but there are also many explosions. The current market competition is extremely fierce. In order to reduce the cost of batteries, some unscrupulous businesses use inferior plates, which can easily cause short circuits and even cause batteries to catch fire and explode.

Method 1: Check the appearance and packaging

Method 2: Look at the product battery

Method 3: Test live working

Method 4: compare weight

Method 5: Detect internal resistance and maximum current

Will lithium polymer batteries explode? How to prevent lithium ion battery from exploding? Polymer lithium ion battery is a kind of lithium ion battery product made of flexible packaging and polymer electrolyte. It will not explode under normal use and storage, unless it is caused by man-made damage to cause a short circuit. Lithium-ion batteries are flammable devices. Devices with built-in lithium-ion batteries such as mobile phones and scooters will always explode if used improperly.

People often have a misunderstanding when charging: it is best to maintain a fully charged state. Perhaps for obsessive-compulsive disorder, when the battery level jumps from 100% to 99%, it will kill him, but in fact, keeping the phone in a charged state is not a recommended behavior, especially after the device is fully charged. The battery of the mobile phone can't bear such a toss.

High-rate lithium-ion batteries can be divided into three common types: steel shell cylindrical batteries, square aluminum shell batteries, and aluminum plastic film soft-pack batteries according to the cell shell. They have their own advantages and disadvantages.

Because of the different processing methods, lithium ion batteries are divided into wound lithium ion batteries and laminated lithium ion batteries. They have different principles and have the same performance. Then what is the difference between the lithium ion batteries produced by these two methods? Which is better?

Many people are elusive about newly-purchased lithium batteries. The author summarized 10 tips on how to use lithium batteries, and share them with you, hoping to help.

The quality of the charger directly determines the length of the life of the lithium-ion battery, so it is very important to choose a good quality charger. The output voltage of the charger must be matched according to your battery.

I believe that most consumers have heard that the life of a lithium battery is "500 times", 500 times of charge and discharge, beyond this number, the battery will "end of life", many friends in order to be able to extend the battery life, every time The battery is charged only when it is completely exhausted. Does this really extend the life of the battery? the answer is negative. The life of a lithium battery is "500 times", which does not refer to the number of times of charging, but a cycle of charging and discharging.

The use of chargers allows many electronic devices to operate normally. Without chargers, our lives will be troubled to a certain extent. In order to enhance everyone's understanding of the charger, this article will introduce the wireless charger related content, mainly to analyze whether the wireless charger is harmful to the mobile phone and explain the precautions of the wireless charger.
