LITHIUM BATTERIES

High energy and long cycles

All-solid-state lithium batteries typically suffer from low coulombic efficiencies and lithium dendrite growth at high current densities. Now, a silver–carbon composite anode is demonstrated that mitigates some of these problems, even for a prototype cell with a high energy density of over 900 Wh L–1.
