Lithium air batteries were developed

According to foreign media reports, researchers have designed new lithium batteries that may have five times more electricity than current lithium batteries. The design uses lithium to react with oxygen extracted from the air, reducing the weight of the lithium battery, which may be used in mobile phones, laptops and electric vehicles in the future, and may even extend the range of electric vehicles.

The team was led by Amin Salehi-Khojin of the University of Illinois and Larry Curtics of the Argonne National Laboratory. The team put forward many design ideas aimed at limiting the chemical reactions in the battery so that the product prototype of its lithium air battery can successfully achieve 700 charge and discharge.

The battery is coated with a thin, amorphous carbon coating of lithium carbonate on the anode of the battery, which facilitates the flow of lithium ions while blocking larger oxygen molecules and carbon dioxide. The team also developed a new electrolyte that uses an Ionic solution called 1-ethyl-3-methylimidazole tetrafluorobonate and dimethyl sulfoxide.

The key to this lithium air battery is its cathode, where negatively charged electrodes enter the battery and pull oxygen out of the air. After the metal edges and Ionic solutions in the electrolyte are combined, a catalyst is synthesized to react lithium with oxygen to produce lithium peroxide.

The catalyst can inhibit other reactions as much as possible, such as the formation of lithium oxide. This reaction process can not be avoided. Lithium oxide can react with carbon dioxide, nitrogen, or water in the air, affecting the performance of the battery.
