  How fast charging of mobile phones affects18650 battery 3.7v 6000mah life!

  "I feel safe! When the girl next to me shouted this sentence, I thought she was talking about the warm man, but it was actually the mobile phone she just bought - a mobile phone that charges for 5 minutes and can talk for n hours.

  Most people will feel restless and anxious when the18650 battery 3.7v 6000mah icon in the upper right corner of their mobile phone turns red when the18650 battery 3.7v 6000mah power drops below 10%. The practicality of fast charging also makes more and more people willing to choose mobile phones with fast charging function.

  Currently, the mainstream fast charging technologies used in mobile phone applications include Qualcomm QuickCharge2.0 (the latest is QuickCharge3.0), MediaTek PumpExpress and OPPOVOOC flash charging. Qualcomm and MediaTek both use high-voltage charging, while VOOC flash charging uses high-current charging.

  The latest Meizu PRO6 is also equipped with fast charging technology. Its poster has this sentence: "Why do they never talk about18650 battery 3.7v 6000mah life when they talk about fast charging?

  Will fast charging affect18650 battery 3.7v 6000mah life?

  Quickly learn about lithium-ion batteries

  First of all, we need to understand the charging and discharging principles of lithium-ion batteries. The18650 battery 3.7v 6000mah has two poles: the positive electrode is lithium compound, and the negative electrode is graphite.

  Charging and discharging are all conversions of electrical energy and chemical energy. During the movement of lithium ions in the positive and negative electrodes, they are also changing into different compounds.

  We can think of lithium ions as cars equipped with electric charges: when charging, due to the electric field, all the cars drive to the negative electrode to store a certain amount of energy (lithium ions are embedded in the micropores of the graphite carbon layer of the negative electrode); when discharging, These charged lithium ion cars run to the positive electrode due to chemical reactions (the deintercalation of lithium ions makes the positive electrode in a lithium-rich state). In this process, a current supply is formed.

  Ideally, as long as the chemical structure of the positive and negative electrode materials basically does not change, the reversibility of18650 battery 3.7v 6000mah charge and discharge is very good, and the lithium-ion18650 battery 3.7v 6000mah can ensure long-term circulation.
