As lithium-ion batteries continue to improve in both performance and cost, it is becoming increasingly difficult for alternative technologies to challenge the incumbent. However, interest in solid-state batteries, which promise better energy density and safety, has increased significantly recently.
Like lithium-ion batteries, solid-state batteries store and release energy to devices. But instead of the liquid or polymer gel electrolytes used in lithium-ion cells, solid-state batteries rely on a solid electrolyte.
Building on this principle, researchers at the University of Chicago have developed a new sodium-based solid electrolyte that reportedly can maintain performance even at subzero temperatures.
