Analyze the differences between lithium batteries and lithium-ion batteries in use

Lithium batteries and lithium-ion batteries are rapidly gaining popularity. In the literature and in real life, people find that lithium batteries and lithium-ion batteries are sometimes similar in use and sometimes interchangeable. The reason is that, Lithium batteries and lithium-ion batteries are a pair of concepts that are different from each other and have inheritance and development relationships. No wonder people confuse them.

The so-called lithium battery is a general term for batteries that use metallic lithium as a negative active substance, while lithium ion batteries refer to two different lithium embedded compounds that can be irreversibly embedded and deem bedded in lithium ions as the secondary battery system of the positive and negative poles of the battery, respectively., The similarities between lithium batteries and lithium-ion batteries are on positive poles and electrolytes. Both batteries use metal oxides and sulphides as positive poles, and organic solvents and inorganic salt systems are used as electrolytes.

Lithium batteries and lithium-ion batteries are a process of development. Lithium batteries are a type of material with lithium metal or lithium alloy as a negative electrode material. The chemical reaction is a Redox reaction. Later, Sony invented carbon material as a negative electrode. Lithium batteries with lithium-containing compounds as positive poles, during the charging and discharging process, there is no metallic lithium, only lithium ions, which is a lithium-ion battery.

Strictly speaking, the working mechanism of lithium batteries and lithium ion batteries is different. Lithium batteries are primary batteries, also known as lithium primary batteries. They can be discharged continuously or intermittently. Some lithium batteries can be used as reserve batteries. For example, applications in hydro power, wind power, solar power stations, etc.. The lithium-ion battery is a secondary battery that can be used repeatedly. Nowadays, many people customarily call "lithium-ion batteries" also known as "lithium-ion batteries". This is a convenient term.

From the point of view of use, lithium batteries and lithium ion batteries in the strict sense are also different. The negative electrode of the lithium battery is metallic lithium, and the positive electrode is MnO2, SOCl2, etc.. After it was put into practical use in the 1970s, it was mainly used in some military and civilian small appliances. Lithium-ion batteries have a wider range of applications, such as mobile phones, cameras, cameras, and laptops. The application of large-capacity lithium-ion batteries in electric vehicles has also entered the industrialization process. From the development trend of lithium-ion batteries and lithium-ion batteries, the application field of lithium-ion batteries has been expanding, while the application field of lithium-ion batteries has been shrinking.

Lithium batteries and lithium-ion batteries may be confused in practice, but there is a fundamental difference between them: Lithium-ion batteries react without lithium metals, and only lithium ions move between positive and negative poles. Therefore, they are also called "rocking chair batteries." Lithium batteries and lithium-ion batteries can be respected in life, but this does not prevent people from understanding the theoretical difference between the two.
