Classification Of Lithium Batteries

With the development of science and technology, lithium battery products have now become mainstream. Lithium batteries are a type of battery made of lithium metal or lithium alloy as a negative electrode material and using a non-aqueous electrolyte solution. They can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. In the literature and in real life, lithium batteries and lithium ion batteries are a pair of concepts that are different from each other and have a relationship of inheritance and development. With the more and more widespread use of lithium ion batteries, people generally refer to lithium ion batteries as lithium battery.

Lithium metal batteries were first developed and researched in 1912. They can also be called lithium primary batteries. It is a kind of disposable battery, mainly including lithium manganese and lithium iron batteries. Lithium metal batteries can be discharged continuously or intermittently. Once the power is exhausted, they can no longer be used and cannot be recharged. Charging can easily cause an explosion.

Lithium-ion batteries refer to two different, reversible, lithium-intercalation compounds that intercalate and deintercalate lithium ions as the battery's positive and negative electrodes, respectively. The lithium-ion battery can be recharged. Lithium batteries and lithium-ion batteries have the same point on the positive electrode and the electrolyte. Both batteries use metal oxides and sulfides as the positive electrode, and organic solvents or inorganic salt systems as the electrolyte.
