What Is Lithium-air Battery in New Lithium Battery Technology?

Li-Air battery is a large-capacity lithium-ion battery jointly developed by the Japanese Technologies Institute (Japanese Technologies Institute, referred to as "Li-Air") and "Li-Air" (Japanese of Japanese, referred to as JSPS). The cathode of the battery is lithium metal, and the anode is oxygen in the air. The two electrodes are separated by a solid electrolyte; the electrode uses an organic electrolyte, and the electrode uses a water-based electrolyte.

During the discharge process, the negative electrode dissolves in the organic electrolyte solution as lithium ions, and then enters the aqueous electrolyte of the positive electrode through the solid electrolyte; this project plans to study a new renewable energy-electrode material-electrode material system, and use this system to electrode The material undergoes processes such as charging and discharging, discharging, and discharging to achieve effective control of the performance of the electrode material. During the charging and discharging process of the battery, electrons are transported to the negative electrode through the conductor wire, and lithium ions pass from the aqueous electrolyte of the positive electrode through the solid electrolyte, enter the negative electrode, and chemically react with the negative electrode to form a kind of metallic lithium. At the positive electrode, hydroxyl groups lose electrons to produce oxygen.

By replacing the positive electrolyte and negative lithium, the lithium-air battery does not need to be charged. Its discharge capacity is as high as 50,000 mAh/g and has high energy density. In theory, 30 kg of metallic lithium is equivalent to the release of 40 L of gasoline. energy of. The lithium hydroxide prepared by this method is easy to recover and has no pollution to the environment. However, issues such as the material's cycle stability, energy conversion efficiency, and high rate remain to be solved.

In 2015, the lithium-air battery developed by Gray of the University of Cambridge theoretically achieved an energy utilization rate of more than 90% under "more than 2,000" charge and discharge cycles, further promoting the practical application of lithium-air batteries. International business machine company IBM launched the "Sustainable Transportation" program in 2009, aiming to develop a lithium-air battery suitable for home electric vehicles, which is expected to have a range of about 500 kilometers after a single charge and discharge. Recently, Japan's Asahi Kasei Corporation, Central Glass and others have also participated in this project, and their research results will surely promote the practical application of lithium-air battery technology.

Lithium-air batteries have a wide range of applications and can be used in electric vehicles, drones, solar and wind energy storage and other fields. Compared with traditional lithium-ion batteries, lithium-air batteries have longer service life, higher energy density and lower cost. Moreover, lithium-air batteries also have innovative advantages, which can help us build a low-carbon and environmentally friendly future faster.
