Analyze the difference between lithium batteries and ordinary batteries from the characteristics of materials and energy conversion

What are the differences between lithium batteries and ordinary batteries? The differences between lithium batteries and ordinary batteries can be roughly analyzed from the characteristics of materials and energy conversion: 1. Lithium batteries use lithium cobalt oxide as an important raw material to make rechargeable batteries. It is characterized by high energy conversion, high voltage per battery, and large capacity (same volume). Lightweight, no memory battery, it is the most environmentally friendly battery. But related to other batteries, the price is more expensive. In addition to the large energy, in use, batteries with large capacity are generally not used, and there is a certain risk of explosion and fire. Of course, with the development of technology and the rationalization of protection circuits, lithium batteries are now also used in power vehicles. 2. Ordinary storage batteries are lead-acid batteries, which are mainly made of lead-plate batteries. Lead pollution is serious. But it is very cheap and can be used to make large-capacity, high-voltage batteries. Lithium battery is a kind of battery invented by Edison that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. The reaction equation for battery operation is: Li+MnO2u003dLiMnO2. The reaction is redox reaction and electric discharge. In the past, lithium batteries have not been used for a long time due to the very active chemical properties of metal lithium and high requirements for production, storage, use, and environmental protection. With the development of modern science, lithium batteries have become the mainstream. On February 22, 2016, the International Civil Aviation Organization (icao) announced the prohibition of carrying lithium batteries in luggage. In order to cultivate better varieties, various materials have been studied. Process products that have never been processed before. For example, lithium sulfur dioxide batteries and lithium thionyl chloride batteries are very characteristic. Their positive active materials are also solvents for the electrolyte. This structure only appears in non-aqueous electrochemical systems. Therefore, the research on lithium batteries has also promoted the development of electrochemical theory of non-aqueous systems. In addition to using a variety of non-aqueous solvents, polymer thin film batteries have also been studied.
