They are particularly very promising energy storage systems to replace traditional secondary batteries for space application since URFCs have distinctive advantages over secondary batteries in that they are longterm energy storage systems with extreme high specific energy and without permanent losses by self discharge and capacity limit. They are enabling for many weightcritical portable applications such as space and military energy storage and conversion systems , as well as remote (offgrid) power sources. In this paper , the recent progress of unitized
