Analysis of the charging and discharging mechanisms of lithium batteries

source:Industry News release time:2024-05-09 Hits:     Popular:AG11 battery

  

  The superiority of lithium-ion batteries that we often talk about is related to traditional nickel cadmium batteries (Ni/Cd) and nickel hydrogen batteries (Ni/MH). It has the advantages of high working voltage, high specific energy, long cycle life, low self discharge rate, and no memory effect.

  The most important steps for charging a lithium battery are these three:

  Step 1: To determine if the voltage is less than 3V, pre charge with a current of 0.05C;

  Step 2: Determine that 3V

  Step 3: Determine if the voltage is greater than 4.2V, charge at a constant voltage of 4.20V, and the current decreases with the increase of voltage until it is fully charged.

  Since its inception in 1990, lithium-ion batteries have developed rapidly due to their excellent performance and have been widely used in society. Lithium ion batteries have rapidly occupied many fields with advantages that are unmatched by other batteries, such as well-known mobile phones, laptops, small cameras, and so on.
