![]() ![]() ![]() Using cryogenic electron microscopy, the researchers found that lithium intrinsically forms perfect 12-face polyhedra, as pictured on the cover. In this week’s issue, Yuzhang Li and his colleagues probe the factors that influence lithium-metal deposition and reveal a way to achieve consistent, predictable results. Recharging these batteries requires lithium metal to be reformed at the anode, but this process is affected by the battery’s electrolyte and current collector, which causes the shape of the lithium deposits to vary unpredictably, impairing the battery’s performance. Lithium-metal batteries promise to charge rapidly and to hold more energy than batteries based on lithium ions. ![]()
