Do you know anything about the working principle of lithium batteries?

Lithium batteries are a type of batteries that use lithium metal or lithium alloy as the negative electrode material and use a non-aqueous electrolyte solution. Lithium battery is a kind of rechargeable battery, it mainly depends on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when recharging the battery, Li+ deintercalates from the positive electrode and inserts into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Generally, batteries that use materials containing lithium as electrodes are representative of modern high-performance batteries. The working principle of lithium battery refers to its charging and discharging principle. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon as the negative electrode has a layered structure. It has many micropores. The lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer. The more lithium ions are inserted, the higher the charging capacity. Lithium batteries use carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. There is no metal lithium, only lithium ions, which is a lithium battery. The charging and discharging process of lithium batteries is the process of intercalation and deintercalation of lithium ions. In the process of intercalation and deintercalation of lithium ions, it is accompanied by the intercalation and deintercalation of electrons equivalent to lithium ions. During the charging and discharging process, lithium ions are intercalated/deintercalated and intercalated/deintercalated back and forth between the positive and negative electrodes, which is vividly called the rocking chair battery. During charging, Li+ in the positive electrode and Li+ in the electrolyte gather to the negative electrode to obtain electrons, which are reduced to Li and embedded in the carbon material of the negative electrode. During discharge, Li embedded in the carbon material of the negative electrode loses electrons and enters the electrolyte, and the Li+ in the electrolyte moves to the positive electrode. Generally, the charging current of lithium batteries is set between 0.2C and 1C. The larger the current, the faster the charging and the greater the battery heat. Moreover, charging with an excessive current will result in insufficient capacity because the electrochemical reaction inside the battery takes time.
