Lithium battery refers to a battery containing lithium (including metallic lithium, lithium alloy and lithium ion, lithium polymer) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are usually non-rechargeable and contain metallic lithium. Lithium ion batteries do not contain metallic lithium and are rechargeable. The contents of rechargeable lithium ion batteries and lithium ion polymer batteries are different. With the development of microelectronics technology at the end of the 20th century, the number of miniaturized devices has increased, and high requirements have been placed on power sources.
