18650 lithium battery 2600mah

release time:2024-04-19 Hits:     Popular:AG11 battery

  Why do 18650 lithium battery 2600mah phosphate batteries expand?

  1. Overcharging causes the lithium battery to bulge.

  Excessive charging will cause the lithium molecules in the battery cathode material to completely enter the battery cathode material, causing the original round grid of the cathode to deform and collapse. This is the main reason for the reduction in battery capacity of 18650 lithium battery 2600mah phosphate batteries. As the number of lithium-ion batteries on the negative stage increases, the excessive deposition of lithium molecules causes them to grow into tree-shaped crystals, which in turn causes the lithium battery to expand.

  2. Bulge caused by power loss.

  When the lithium liquid rechargeable battery is first charged, the metal electrode and the lithium battery electrolyte react on the solid liquid phase to form a passivation layer that covers the surface of the metal electrode.

  The passivation film formed can effectively block the basis of the molecular structure in the lithium battery electrolyte, but Li+ can be freely inserted and resin-adsorbed through the passivation layer, and has the characteristics of a solid electrolyte, so this passivation film is called It's called SEI. The SEI film is not static. A small amount of changes will occur during the charging process, mainly because some organic compounds will undergo reversible changes.

  Excessive charging and discharging of the 18650 lithium battery 2600mah phosphate battery pack caused reversible damage to the SEI plastic film, which protected the battery's positive electrode material SEI and caused it to collapse, thus causing the packaging phenomenon.

  3. It’s a matter of production and manufacturing standards.

  The manufacturing level of 18650 lithium battery 2600mah phosphate battery packs has problems with packaging, the electroplating of lithium battery packs is uneven, and the production process is relatively rough.

  4. The 18650 lithium battery 2600mah phosphate battery pack may bulge if it is not used for a long time. Since gas is conductive to a certain extent, charging and discharging for too long is equivalent to direct contact between the positive and negative electrodes of the battery, resulting in long-term short circuit failure.
