Lithium Battery

Samsung note7 phone explosion caused a hubbub, to the Samsung Group has brought huge losses. Samsung cell phone explosion is due to cell phone lithium battery quality failure, the battery spontaneous combustion or explosion. Now almost all cell phones use lithium batteries, then, what kind of lithium battery will burn or explode?

First of all, we first look at the lithium battery. Lithium battery is a kind of lithium metal or lithium alloy as the anode material, the use of non-aqueous electrolyte solution of the battery. Lithium batteries can be divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain lithium metal, and can be charged. Lithium metal batteries are disposable batteries, can not charge.

Therefore, mobile phone lithium batteries are rechargeable lithium-ion battery. Lithium batteries mainly by the anode, cathode, diaphragm, electrolyte and other components. In some Samsung mobile phones note7, due to defects in the diaphragm, the original can not touch each other with the battery yin and yang bipolar touch together, a short circuit, resulting in abnormal heating of the battery, and ultimately the occurrence of combustion and explosion.

Well, Samsung mobile phone explosion reason has been understood. So, what kind of lithium battery is safe? This is closely related to the production process of battery manufacturers.

Mobile phone lithium battery mainly by the plastic shell cover, lithium batteries, protection circuit boards and recoverable fuse. Some manufacturers also configure the NTC (negative temperature coefficient thermistor), identify the resistance, vibration motor or charging circuit and other components. It can be seen, good quality lithium battery is a lot of security.

In fact, lithium batteries are durable goods, it is not precious, it will not easily explode. Only the poor quality of the lithium battery will happen bad things.
