Sentences with phrase «flow battery»
A "flow battery" is a type of rechargeable battery that stores and releases energy using two different liquids, called electrolytes. The liquids flow through the battery while producing electrical energy. Flow batteries are capable of storing large amounts of energy and can be used in renewable energy systems or as backup power sources. Full definition
