18650 battery 1800 mah.18650 lithium battery charging and discharging principles

release time:2024-01-04 Hits:     Popular:AG11 battery

  

  The working principle of lithium-ion batteries refers to their charging and discharging principles. When charging the battery, lithium ions are generated on the positive electrode of the battery, resulting in the generation of lithium

  Ions move through the electrolyte to the negative electrode. As the negative electrode, carbon has a layered structure with many micropores, and lithium ions that reach the negative electrode are embedded into the micropores of the carbon layer. The more lithium ions embedded, the higher the charging capacity.

  Similarly, when discharging the battery (i.e. during the process of using the battery), the lithium ions embedded in the negative carbon layer detach and move back to the positive electrode. The more lithium ions return to the positive electrode, the higher the discharge capacity. The battery capacity we usually refer to is the discharge capacity.

  It is not difficult to see that during the charging and discharging process of lithium-ion batteries, lithium ions are in a motion state from positive electrode to negative electrode to positive electrode. If we vividly compare lithium-ion batteries to a rocking chair, with the two ends of the rocking chair being the two poles of the battery, and lithium-ion batteries are like excellent athletes running back and forth between the two ends of the rocking chair. So, experts have given lithium-ion batteries a cute name, rocking chair battery.
