Lithium-ion flow battery : ウィキペディア英語版 | Lithium-ion flow battery A lithium-ion flow battery is a flow battery that uses a form of lightweight lithium as its charge carrier. The flow battery stores energy separately from its system for discharging. The amount of energy it can store is determined by tank size; its power density is determined by the size of the reaction chamber. Dissolving a material changes its chemical behavior significantly. Flow batteries suspend grains of solid material in a liquid, which preserves its characteristics, making lithium's high energy density available to flow systems. == Lithium polysulfide ==
One device uses dissolved sulfur as the cathode, lithium metal as the anode and an organic solvent as the electrolyte. Officially "membraneless", it uses a coating to separate anode from cathode. It uses a single tank and pump and reacts the LiS with lithium to produce power. The device operated for more than 2000 cycles without substantial degradation.〔 When discharging, the lithium polysulfide absorbs lithium ions; releasing them when charging.〔 The demonstration device yielded energy density of 97 Wh/kg and 108 Wh/L with a 5M catholyte.〔
