What is a lithium battery?

Lithium battery refers to the battery containing lithium (including metal lithium, lithium alloy, lithium ion and lithium polymer) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium metal batteries are usually non rechargeable and contain metallic lithium. Lithium ion batteries do not contain metallic lithium and can be recharged. Lithium metal battery is a kind of battery with lithium metal or lithium alloy as cathode material and non-aqueous electrolyte solution.

What industry are lithium batteries mainly used in?

Lithium batteries are widely used in energy storage power supply systems such as hydraulic, thermal, wind and solar power stations, uninterruptible power supply for posts and telecommunications, as well as electric tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields. Lithium ion battery has been widely used in portable appliances such as laptop, camera and mobile communication because of its unique performance advantages.

Development prospect of lithium battery

At present, the developed high-capacity lithium-ion battery has been put into trial use in electric vehicles. It is expected to become one of the main power sources of electric vehicles in the 21st century, and will be applied in artificial satellites, aerospace and energy storage. With the shortage of energy and the pressure of environmental protection in the world. Lithium battery is now widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate battery, which promotes the development and application of lithium battery industry.

Lithium sulfur dioxide batteries and lithium thionyl chloride batteries have their own characteristics. Their positive active material is also the solvent of electrolyte. This structure only appears in the electrochemical system of non-aqueous solution. Therefore, the research of lithium battery also promotes the development of electrochemical theory of non-aqueous system. In addition to using various non-aqueous solvents, polymer thin film batteries have also been studied.

"Super" lithium battery: the newly developed super lithium battery can be charged quickly in a short time. For example, mobile phone charging is generally 20 seconds. This kind of battery may increase the future application field of the battery, for example, it can be used in electric vehicles, so that the midway charging is as convenient as refueling.
