米国におけるフロー電池エネルギー貯蔵技術の新たなブレークスルー-リチウムイオンバッテリー機器
2023年7月21日
A new combination of materials developed by researchers at Stanford University in the US could help create a rechargeable battery that can efficiently store large amounts of emerging renewable energy from wind to solar. With further development, this technology could deliver energy to the grid quickly, at low cost, and at normal ambient temperatures.(Lithium - Ion Battery Equipment)
Known as flow battery technology, the technology has long been considered one of the options for storing intermittent renewable energy. However, to date, the types of liquids in which an electric current can occur have the following disadvantages: being limited by the amount of energy that can be transferred; requiring extremely high temperatures; and requiring the use of highly toxic or very expensive chemicals.
An assistant professor of materials science and engineering at Stanford University and his doctoral students decided to try potassium and sodium. They mixed potassium and sodium at room temperature into a liquid metal that serves as the battery's electron donor or fluid for the negative electrode. In theory, this liquid metal has at least 10 times more usable energy per gram than other materials. The researchers said: "We still have a lot of work to do. This is a new type of affordable flow battery that can use earth-abundant materials to make more efficient use of solar and wind energy." (Source: Stanford University, USA)
