摘要：
Sodium metal-based batteries have been identified as an exciting new solution to the challenge of Long Duration Energy Storage (LDES) applications. Enlighten Innovations, Inc. (EII) has developed a novel, low-cost Sodium Metal - Sodium Polysulfide Flow Battery (SPFB) enabled by its proprietary NaSICON (Sodium Super Ionic Conductor) ceramic solid-state separator. EII's SPFB truly decouples the energy and power, unlike other metal-based batteries. EII's SPFB operates at intermediate temperatures (below 125 degrees C) enabling the use of low-cost materials of construction avoiding expensive sealing and manufacturing technologies of the current state of the art that results in an estimated system-level Levelized Cost of Storage (LCOS) cost of similar to $0.1/kWh, which is the lowest among the current battery technologies. EII is now taking next steps towards kW scale stack performance demonstration and large-scale manufacturing.
