In developing a versatile new electrolyte, a team of University of Wisconsin–Madison engineers has taken the next step toward a more efficient, energy-dense battery that could supplant today’s ubiquitous lithium-ion batteries. This new battery type—an initially anode-free sodium-ion battery—is a leading candidate for powering future electric vehicles or storing energy in the electrical grid.
