Lithium batteries are a type of batteries that use lithium metal or lithium alloy as a negative electrode material and use a nonaqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison, using the following reaction: Li+MnO2=LiMnO2 This reaction is redox reaction and discharge. Because the chemical properties of lithium metal are very lively, the processing, preservation, and use of lithium metal require very high environmental requirements. Therefore, lithium batteries have not been applied for a long time. Lithium batteries have now become mainstream.
Application of Lithium Batteries With the development of microelectronics in the 20th century, miniaturized devices are increasing, placing high demands on power supplies. Lithium batteries have subsequently entered a large-scale practical stage.
The earliest applications were lithium sub-batteries for use in cardiac pacemakers. Since the lithium sub-battery has a very low self-discharge rate, the discharge voltage is very gentle. This makes it possible to implant pacemakers into the body for long periods of time.
Lithium-manganese batteries generally have a nominal voltage higher than 3.0 volts, and are more suitable for integrated circuit power, and are widely used in computers, calculators, and watches.
Nowadays, lithium-ion batteries are widely used in mobile phones, notebook computers, power tools, electric vehicles, street lamp backup power supplies, navigation lights, and household appliances, and can be said to be the largest application group.
Research and Development Prospects of Lithium Batteries In order to develop more excellent varieties, various materials have been studied. To create an unprecedented product. For example, lithium sulfur dioxide batteries and lithium thionyl chloride batteries are very characteristic. Their positive electrode active material is also a solvent for the electrolyte. This structure only appears in non-aqueous electrolyte systems. Therefore, the study of lithium batteries has also promoted the development of the electrochemical theory of non-aqueous systems. In addition to the use of various non-aqueous solvents, research has also been conducted on polymer thin-film batteries.
Lithium batteries are widely used in energy storage power systems such as hydraulic power, fire power, wind power and solar power stations, uninterrupted power supplies for post and telecommunications, and power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, and aerospace.
Lithium-ion batteries have been widely used in portable appliances such as laptops, video cameras, and mobile communications because of their unique performance advantages. The current development of large-capacity lithium-ion batteries has begun trials in electric vehicles and is expected to become one of the main power sources for electric cars in the 21st century, and will be used in artificial satellites, aerospace and energy storage. With the shortage of energy and the pressure of the world's environmental protection. Lithium is now widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate materials, but also promoted the development and application of lithium battery industry.
