QuantumScape Corp., the electric-vehicle battery company that went public last fall, said Tuesday it has advanced to testing 10-layer cells, a sign it’s on track in efforts to develop a commercially viable solid-state battery.

QuantumScape, which counts Volkswagen AG as its biggest shareholder, is among a group of companies developing solid-state batteries, which could dramatically speed up EV adoption by providing a safer, cheaper alternative to current lithium-ion batteries. It has benefited from booming investor interest in electric cars and the technology needed to make and improve them.
