AG13 battery.Working principle of lithium-ion batteries

　　A lithium battery with carbon material as the negative electrode and lithium containing compounds as the positive electrode does not exhibit any charge and discharge processes

　　Lithium metal exists, only lithium ions exist, which is the lithium-ion battery. When charging the battery, the positive voltage of the battery

　　Lithium ions are generated on the electrode, and the generated lithium ions move through the electrolyte to the negative electrode. And as the negative electrode, carbon forms a layer

　　The shaped structure has many micropores, and the lithium ions that reach the negative electrode are embedded into the micropores of the carbon layer, and the embedded lithium ions are separated from each other

　　The more seeds there are, the higher the charging capacity. Similarly, when discharging the battery (i.e. the process of using the battery),

　　The lithium ions embedded in the negative carbon layer are released and then move back to the positive electrode. The more lithium ions are returned to the positive electrode, the higher the discharge capacity. The battery capacity we usually refer to is the discharge capacity. During the charging and discharging process of Li ion, the lithium ion is in a state of motion from positive electrode to negative electrode to positive electrode. Li ion Batteries are like a rocking chair, with the two ends of the rocking chair serving as the poles of the battery, while lithium ions run back and forth like athletes. So Li ion

　　Batteries, also known as rocking chair batteries.

　　Generally, the charging current of lithium batteries is set between 0.2C and 1C. The higher the current, the faster the charging. At the same time

　　The heat generated by the pool also increases. Moreover, excessive current charging results in insufficient capacity due to the electrochemical reactions inside the battery

　　It should take time. Just like pouring beer, pouring too fast will produce foam, but dissatisfaction.
