Electric tool protection board manufacturers come to popularize the working principle of lithium batteries

The manufacturer of electric tool protection plates stated that lithium-ion batteries use carbon materials as the negative electrode and lithium containing compounds as the positive electrode. During the charging and discharging process, there is no metallic lithium present, only lithium ions, which is known as lithium-ion batteries. When charging the battery, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move through the electrolyte to the negative electrode. As the negative electrode, carbon has a layered structure with many micropores. The 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 of the electric tool protection plate manufacturer.

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 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.

The absence of memory effect is also a prominent advantage of lithium-ion batteries, which other secondary batteries do not possess. Before charging lithium-ion batteries, it is not necessary to consider whether the battery has been used up. The major characteristic of lithium batteries is their high specific energy.

Generally, the charging current of lithium batteries is set between 0.2C and 1C. The larger the current, the faster the charging, and at the same time, the battery generates more heat. Moreover, excessive current charging results in insufficient capacity, as the electrochemical reactions inside the battery require time. Just like pouring beer, pouring too fast will produce foam, but dissatisfaction.
