Japanese media said that Japanese companies have successively developed technologies that greatly increase the service life of air batteries. Service life is the biggest issue of air batteries known as the "ultimate battery." The hydrogen-air fuel cell developed by Fujitsu's FDK company is expected to be practical in 3 years. Japan Telecom and Telephone Corporation (NTT) trial-produced a lithium-air battery with a long service life. According to a report by Japan Economic News on March 18, air batteries are not only lightweight but also have high performance. Various devices need to collect data, and the demand for air batteries will increase day by day. If storage systems for surplus electricity generated by renewable energy such as solar energy are popularized, carbon dioxide emissions are expected to be greatly reduced. According to reports, with the advent of lithium batteries, portable devices are rapidly gaining popularity, supporting the development of the IT revolution. Lithium battery performance continues to improve and is an important component to support the electrification of automobiles. However, lithium battery technology is gradually approaching the limit, and it also has shortcomings such as flammability. Air batteries are a powerful candidate for a new generation of technology that can generate electricity by chemically reacting with oxygen in the air. Since oxygen can be supplied indefinitely, the storage capacity of air batteries can theoretically reach 5 to 10 times that of lithium batteries. It is reported that the air battery developed by FDK generates electricity by allowing hydrogen and oxygen to react chemically. The structure of a nickel-metal hydride battery used in a hybrid car or the like is effectively used, the positive electrode using nickel is replaced with oxygen, and fine particles whose main component is ruthenium are added to promote the reaction. Even after performing 500 charge and discharge, the performance degradation rate is less than 10%. If it is used to store renewable energy power, it can be used for about 10 years. NTT has developed a lithium-air battery that uses lithium as the negative electrode. Even if it is charged and discharged 100 times, its performance will not decrease. Adding a compound whose main component is manganese is the key, which can play a catalytic role and promote the chemical reactions necessary for charging and discharging. If according to the previous method, after several charge and discharge, battery performance will decline.
