Brief description of the principle of lithium battery

The so-called lithium battery is a secondary battery that uses two materials that can intercalate and deintercalate lithium ions as the positive and negative electrodes of the battery to realize the function of recharging and discharging repeatedly. Lithium batteries rely on the transfer of lithium ions between the positive and negative electrodes to complete battery charging and discharging operations. When the battery is charged and discharged, Li+ flows between the positive and negative electrodes. When discharging, the anode oxidizes and loses electrons, while the cathode reduces to obtain electrons; when charging, the direction of charge movement is opposite. Lithium battery principle structure Lithium battery is divided into lithium battery and lithium battery. Currently, mobile phones and notebook computers use lithium batteries, which are commonly referred to as lithium batteries. Lithium batteries are currently used in mobile phones, but real lithium batteries are not used in daily electronic products because of their high risk. In the process of intercalation and deintercalation of lithium ions, it is accompanied by the intercalation and deintercalation of electrons equivalent to lithium ions (the positive electrode is used to declare the insertion or deintercalation, and the negative electrode is used for the piercing or deintercalation declaration). During the charging and discharging process, lithium ions are intercalated/deintercalated and pierced/deintercalated back and forth between the positive and negative electrodes, which is vividly called the rocking chair battery. Lithium batteries have high energy density and high uniform output voltage. The self-discharge is small, below 10% per month. There is no memory effect. The wide operating temperature range is -20～60. Excellent cycle performance, fast charging and discharging, charging power up to 100%, and high output power. Long service life. There is no environmental pollution and it is called a green battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
