流動溶液電池flow battery,液流電池,redox flow battery,氧化還原液流電池)係用氧化還原嘅一種化學電池。由兩唔同嘅化學溶液,用佢哋,等佢哋向一個方向流,兩隻溶液到咗塊透釋膜上面,做離子交換嘅化學反應[2][3]

Redox Flow Battery
化學溶液存喺兩個缸裏面,將溶液去塊透釋膜上面做氧化還原[1]

流動溶液電池可以好似燃料電池咁,化學溶液嘅物質用完,可以加返啲新嘅溶液;亦可以好似充電池咁,化學溶液嘅物質用完,可以叉返電,即係用電源反轉氧化還原反應;好在幾乎可以無限次翻叉。個缸嘅容量決定cho2電嘅量,個缸越大,cho2嘅電量越多,亦即係好易擴大個規模(scale up),同埋透釋膜嘅面積大細影響輸出[4]

呢隻電池有唔同嘅種類型,包括無機流動溶液電池[5]同有機流動溶液電池[6]。喺每個類別之下,設計可以細分做全液流電池、半液流電池同冇膜液流電池。傳統電池同液流電池嘅根本區別係,能量存cho2喺傳統電池嘅電極材料之中;液流電池,能量儲喺電解液之中。
