Principles and uses of lithium batteries

What is a mobile phone lithium battery? What is a lithium battery? Lithium batteries are divided into lithium batteries and lithium batteries. Currently, mobile phones and notebook computers use lithium batteries, commonly known as lithium batteries, but real lithium batteries are rarely used in daily electronic products due to their dangers. Lithium batteries Lithium batteries use carbon data as the negative electrode and lithium-containing compounds as the positive electrode. There is no lithium metal, only lithium ions, and this is a lithium battery. Lithium battery refers to a data battery in which lithium ions are intercalated into a compound as a positive electrode. The charging and discharging process of lithium batteries is the intercalation and deintercalation process of lithium ions. In the process of lithium ion embedding and de-embedding, it is accompanied by the embedding and de-embedding of lithium ion equivalent electrons. During the charging and discharging process, lithium ions are inserted/pulled out between the positive electrode and the negative electrode, and lithium ions are inserted/pulled out. This is what we know as the rocking chair battery. Lithium battery has high energy density and uniform output voltage. Small self-discharge, no memory effect; good cycle performance, fast charging and discharging, charging power up to 100%, high output power; long service life, no toxic and harmful substances, and it is called a green battery. What is a mobile phone lithium battery? The mobile phone lithium battery is mainly covered by a plastic casing and moves up and down. Lithium batteries, repairs, circuit boards (PCB) and recyclable fuses (polysilicon). Some manufacturers are also equipped with components such as NTC, identification resistors, vibration motors or charging circuits. Lithium batteries are durable consumer goods, so they are not exquisite. We can wait for it with peace of mind. Don't give it expensive original seats. There is a brand of ordinary seats that can be charged. The price is 15-20 yuan, which directly eliminates the need for restricting mobile phones. Mobile phone lithium battery function (1) Lithium battery: supply rechargeable discharge power. (2) Maintain the circuit board (PCB): prevent the battery from overcharging, overdischarging and short circuit. (3) Recoverable fuse (PTC): The positive thermistor is used for high temperature maintenance together with secondary maintenance after the maintenance circuit board fails. (4) Recovery fuse (NTC): Negative thermistor, so that the internal temperature of the induction battery can achieve low-temperature maintenance. (5) Identification resistance: Identify original batteries and non-original batteries cannot be used. (6) Automatic storage of emergency power supply.
