What are the differences between lithium batteries and mobile phone lithium batteries

Lithium batteries use carbon material as the negative electrode and lithium-containing compounds as the positive electrode. There is no metal lithium, only lithium ions, which is a lithium battery. Lithium battery refers to the general term for batteries with lithium ion intercalation compound as the cathode material. The charging and discharging process of lithium batteries is the process of intercalation and deintercalation of lithium ions. In the process of intercalation and deintercalation of lithium ions, it is accompanied by the intercalation and deintercalation of electrons equivalent to lithium ions. In the process of charging and discharging, lithium ions are intercalated/deintercalated and intercalated/deintercalated back and forth between the positive and negative electrodes, which is vividly called the rocking chair battery. Lithium battery has high energy density, high average output voltage; low self-discharge, no memory effect; superior cycle performance, fast charge and discharge, charging efficiency up to 100%, and high output power; long service life, no toxic and harmful substances, It is called a green battery. What is a mobile phone lithium battery? A mobile phone lithium battery is mainly composed of a plastic shell upper and lower cover, a lithium battery cell, a protective circuit board (PCB) and a recoverable fuse (polyswitch). Some manufacturers are also equipped with components such as NTC, identification resistors, vibration motors or charging circuits. Lithium batteries are durable goods, so they are not delicate. You can treat them calmly and don’t equip them with expensive original chargers. Generally, there are brands of ordinary chargers, and the price is 15-20 yuan, which is omitted. Direct charging depends on the limitations of mobile phones. Mobile phone lithium battery function (1) Lithium battery: supply rechargeable power supply. (2) Protect the circuit board (PCB): prevent the battery from being overcharged and short-circuited. (3) Recoverable fuse (PTC): The positive thermistor is used for high temperature protection and at the same time is a double protection to protect the circuit board after failure. (4) Recoverable fuse (NTC): negative thermistor, which senses the internal temperature of the battery for low-temperature protection. (5) Identification resistance: Identify original batteries and non-original batteries cannot be used. (6) Automatic reserve of emergency power.
