Introduction to the charging and discharging principles of high-temperature lithium batteries.

The principle of high-temperature lithium batteries refers to its basic principles of charging and discharging. When charging a battery, lithium iron phosphate will enter the positive stage of the charging battery, and the resulting lithium iron phosphate will enter the negative stage based on the electrolyte of the high-temperature lithium battery. Carbon, as a negative layer, has a layered structure with many micropores. Lithium iron phosphate that reaches the negative level is placed into the micropores of carbon. The more lithium iron phosphate is placed, the greater the charging capacity of the battery. Like manufacturers of high-temperature lithium batteries, when rechargeable batteries are charged and discharged (i.e. the entire process of using rechargeable batteries), lithium iron phosphate placed in the negative carbon layer is adsorbed by epoxy resin and moves back to the positive stage again. The larger the reflux rate of lithium iron phosphate, the greater the charge and discharge capacity; The capacity of a rechargeable battery, individually referred to as the capacity for charging and discharging.    

  

During the charging and discharging of high-temperature lithium batteries, lithium iron phosphate moves from positive to negative and then to positive; If everyone compares the image of high-temperature lithium battery companies to a armchair, with two layers of rechargeable batteries on either side of the armchair, and high-temperature lithium batteries are like active fitness enthusiasts, running back and forth on both sides of the armchair. Therefore, experts have given high-temperature lithium batteries another despicable name - chair rechargeable batteries. The charging control of high-temperature lithium battery is divided into two stages. The stage is the constant current power supply battery charging. When the battery voltage decreases, the charging head uses a DC circuit to charge the battery; The second stage is the constant current source charging stage. When the battery voltage is guaranteed to a certain value, due to the characteristics of high-temperature lithium batteries, if the working voltage is even higher, it will be damaged. The charging head will fix the working voltage unchanged, and the current will drop rapidly. When the total current drops to a certain value (some cases are set to 1/10 of the total current), the battery charging circuit is disconnected, and the indicator light for the end of battery charging is on, indicating the end of battery charging.
