Causes of lithium battery detachment.18650 lithium battery 3.7 v

release time:2023-07-13 Hits:     Popular:AG11 battery

  

  (1) The start charging current is too large. Because the reduction of polar plate activated substances starts with the best grid of the conductivity, when the large current is charged, the lead sulfate at that area is quickly restored, so the lead sulfate far away from the grid is not as good as a chemical reaction. Because the lead sulfate volume is compared with the volume of the volume of the leading sulfate, which is compared Large, so the adhesion between the restored activated substances inside is poor, so it is easy to fall off from the pole plate.

  (2) The current current current is too large. In this way, a large amount of air bubbles are generated, and the surface of the pole plate is severely impacted, so that the restored softering leader of lead dioxide drops off.

  (3) Excessive charging. Although the over -charging current is not large, the lead sulfate on the pole plate has all been restored to lead and lead, and the charging current is all used on the electrolyte. Although the bubbles generated at this time The shocking effect on the surface causes the active substance to fall off.

  (4) The discharge current is too large. At this time, the chemical reaction is fierce, which will cause the polar plate warp, which will cause the active substance to fall off.
