Lithium-ion battery operation principals

 

Lithium-ion (LIB) batteries are becoming more and more popular due to having more advantages in respect of competitors:

Electrodes of these batteries are made of light weight Lithium and Carbon. A lot of energy can be stored in lithium bonds due to its highly reactive nature. In the electrochemical reactions the main participants are the positive and negative electrodes and electrolyte serves as a conducting medium for ions to flow in between the electrodes.m In this process both electrodes acts as transparent materials and allow ions to completely cross through their bodies.
During this intercalation or insertion, ions move into the electrode. During the reverse process, de-intercalation or extraction, ions move back out. When a lithium-ion based cell is discharging, the positive Lithium ion moves from the negative electrode (normally graphite is used) and enters the positive electrode (lithium containing compound). And during charging process, reverse process is undertaken.
