　　What is the difference between ordinary batteries and lithium batteries?

　　"Lithium battery" is a kind of battery with lithium metal or lithium alloy as the negative electrode and non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and discussed by Gilbert N. Lewis. In the 1970s, M.S. Whittingham proposed and began to study lithium-ion batteries. Because the chemical characteristics of lithium metal are very vivid, the processing, preservation and application of lithium metal have very high requirements on the environment. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream.

　　Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and can be recharged. Lithium metal battery, the fifth generation of rechargeable battery, was born in 1996. Its safety, specific capacity, self discharge rate and performance price ratio are all better than lithium ion battery. Because of its high skill requirements, only a few countries are producing such lithium metal batteries.

　　1. Lithium battery is a rechargeable battery made of lithium cobalate as the primary raw material. It is characterized by high energy conversion, high voltage of each battery and large capacity (under the condition of equal volume). It is the most environmentally friendly battery with light volume and no memory.

　　But compared with other batteries, they are more expensive, In addition, due to the large energy, it is generally not possible to make a battery with very large capacity during operation, which may lead to a certain risk of explosion and fire. Of course, with the development of skills and the rationalization of maintenance circuits, lithium batteries have also been used in power cars.

　　2. General batteries are lead-acid batteries, which are mainly made of lead plates. These batteries are bulky, bulky and have memories. Lead pollution is severe, but it is cheap and can be used to make high-capacity and high voltage combination batteries.

　　Most of them are used for burning batteries in cars and standby power supply in machine rooms. Of course, there are also risks of fire. Now the country is controlling small enterprises to produce such batteries to avoid pollution expansion.

　　Lithium battery is a kind of battery with lithium metal or lithium alloy as cathode and non-aqueous electrolyte solution, which was created by Edison.

　　The reaction equation of battery application is: Li+MnO2=LiMnO2

　　The reaction is redox reaction and discharge. In the past, lithium batteries were not used for a long time because of the vivid chemical properties of lithium metal and the high environmental requirements for processing, storage and application.

　　With the development of modern science, lithium batteries have now become the mainstream. On February 22, 2016, the World Civil Aviation Arrangement announced that the mailing of lithium battery luggage was prohibited.
