New MIT research: grid-scale batteries one step closer to reality?
Promising news last week from MIT Professor Donald Sadoway's research on liquid-metal batteries for grid-scale storage. MIT News and The Boston Globe report on a new battery structure using innovative metal-mesh membranes, which appear to solve a vexing cost/reliability challenge faced in prior ceramic membrane designs. Says Sadoway, "I consider this a breakthrough."
Full details can be found in the team's new Nature Energy paper "Faradaically selective membrane for liquid metal displacement batteries."
You may recall meeting Professor Sadoway in a Climate Conversations podcast last year. Among other topics, we discussed cost-effective grid-scale batteries ("if you want to make something dirt cheap, make it out of dirt"), and how innovative uses of electrochemistry could reduce the climate impacts of steel manufacturing.
