MIT team improves liquid metal batteries for grid-scale storage; lower operating temperature, cost 22 September 2014 Researchers at MIT have improved a proposed liquid battery system that could enable renewable energy sources to compete with conventional power plants. Professor Donald Sadoway and colleagues have already started a company, Ambri (initially Liquid Metal Battery Corporation), to produce electrical-grid-scale liquid batteries, which comprise layers of molten material which automatically separate due to their differing densities. (Earlier post .) In a paper published in the journal Nature , they describe a lithium–antimony–lead liquid metal battery comprising a liquid lithium negative electrode, a molten salt electrolyte, and a liquid antimony–lead alloy positive electrode, which self-segregate by density into three distinct layers owing to the immiscibility of...
