Honda set up a demonstration facility in Japan to show off its plans to mass-produce solid-state batteries at lower costs, which could be crucial to unlocking higher-range, longer-lasting electric vehicles for the future.

Solid-state batteries have been elusive for many companies due to the complexity of scaling up production. The technology swaps out the liquid electrolytes found in current lithium-ion batteries with dry conductive materials, promising higher energy density and longer lifespans. But it will require a whole new production process to be successful.

Several companies are actively pursuing solid-state batteries, including Volkswagen-backed QuantumScape, Nissan, and Factorial, which is testing semi-solid-state batteries that…
