Critical Resources in solid-state battery breakthrough

Critical Resources Ltd managing director Tim Wither talked with Proactive about the company’s latest manufacturing milestone in its solid-state battery evaluation program, achieved using dynamic spray deposition, or DSD, at the South Dakota School of Mines & Technology within the US National Science Foundation-supported Centre for Solid-State Electric Power Storage research program. Wither explained that the company has successfully deposited a complete cathode, solid electrolyte and conductive network in a single dry step, describing the result as “another demonstration of the work that we are doing with the South Dakota School of Mines.” He said DSD involves applying material at supersonic velocities through a nozzle, with the process allowing control that is “pretty much like 3D printing a battery layer.” The milestone is significant because the process avoids solvents, binders, drying ovens, furnaces and presses, which Wither said could remove several stages normally associated with battery manufacturing. He also highlighted the importance of improving the interface between the cathode and electrolyte, a key technical challenge in solid-state battery development. Wither said the company is now moving from coin cells into full-size power cells, while further work will focus on applying the process to its AC and high-temperature electrolytes. He added that solid-state battery technology could support “more energy for less weight” and help move the industry toward next-generation battery systems.
