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.
Does the wireless charger damage the phone? What should I pay attention to when using a wireless charger?
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. If you are interested in chargers, you might as well continue reading.
Generally, a 3.7V lithium battery needs to have a "protection circuit board" for overcharging and overdischarging. If the battery does not have a protection circuit board, it can only be charged with a voltage of about 4.2V, because the ideal full charge voltage of a lithium battery is 4.2V. If the voltage is exceed 4.2V, the battery may is damaged, it is necessary to monitor the condition of the battery at the same time when charging with this method.
The main components of lithium-ion batteries include positive electrode, negative electrode, electrolyte, separator, positive electrode lead, negative electrode lead, safety device and battery casing, etc. Most of the materials are combustible materials. The distance between the positive and negative electrodes of a lithium-ion battery is extremely short. Any small defect on the separator between the positive and negative electrodes may form a short circuit, causing local high temperature, and causing the separation of the positive and negative electrodes in nearby locations to decompose and chain The reaction will eventually cause the battery to catch fire or explode.
The nature of the ignition of lithium-ion batteries is that the heat in the battery fails to be released according to the design intent, causing internal and external combustion materials to ignite after ignition. The main reasons for the fire are external short circuit, external high temperature and internal short circuit.
