Introduce the discharge knowledge of 18650 lithium ion battery

Discharge of 18650 lithium-ion battery Common rechargeable 18650 lithium-ion battery, the voltage is standard 3.6 or 3.7v, when 4.2v is fully charged, irrelevant power (capacity), the mainstream capacity of 18650 battery is from 1800mah to 2600mah (capacity 18650 power lithium The battery is in the range of 1200~1600mah), and the mainstream capacity even marks the import of 3500 or more than 4000mah lithium-ion batteries. It is generally believed that the no-load voltage is 3.7V when the lithium-ion battery is exhausted. The no-load voltage is 3.7V when the lithium-ion battery is discharged. Otherwise, the battery cannot be over-discharged and the battery will be damaged. 4.2V is the highest limit of the battery voltage. The no-load voltage of 4.2V is that the battery voltage gradually increases during the charging process of the electric battery. The no-load voltage of lithium-ion batteries from 3.7V to 4.2V cannot exceed 4.2V, otherwise the battery will be damaged. Li-ion batteries are special places. The discharge benefit of 18650 lithium-ion battery: It is judged according to the internal resistance of the battery and the current and temperature of the battery during use. Lithium-ion batteries are usually different from old memory batteries. Lithium-ion batteries are manufactured to replace old batteries on the market, not only because they have no memory benefits, but also because they are environmentally friendly, portable, and easy to carry, and because lithium-ion batteries have greater discharge benefits. However, the most basic discharging benefits of lithium-ion batteries are also related to the use of lithium-ion battery raw materials. The choice of high-quality raw materials can reduce the internal resistance of the battery. The charging and discharging benefits of lithium-ion batteries with different anode and cathode materials are different. In addition to the unavoidable internal attenuation of the battery itself, the battery also changes with the use of the environment. Therefore, it is recommended to use 18650 lithium ion batteries at the best room temperature. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
