Honda’s Plan for Solid-State EV Batteries

Honda has established a demonstration facility in Japan to showcase its plans for mass-producing solid-state batteries at reduced costs. This development could be a game-changer in the production of electric vehicles with higher range and longer battery life.

The Challenge of Solid-State Batteries

Solid-state batteries have posed challenges for many companies due to the complexities involved in scaling up production. This innovative technology replaces the liquid electrolytes present in current lithium-ion batteries with dry conductive materials, offering the promise of higher energy density and longer lifespan. However, achieving success with solid-state batteries necessitates the establishment of an entirely new production process.

Honda’s Accelerated Research

Honda is ramping up its research efforts at a new 27,000 square-meter demonstration facility in Sakura City, Japan, with a focus on reducing the production time for a single unit. The facility is equipped with full-scale machinery distributed across three buildings: one for cathode formation and cell assembly, another for anode formation, and a third for electrolyte activation and module assembly.

Streamlined Production Process

Honda’s plan includes utilizing a continuous inline mixer that the company claims is three times faster than traditional cell batch processing methods. The goal is to commence battery production on this line by January.

Future Plans for Mass Production

Honda is preparing its solid-state technology for mass production in the latter half of the 2020s. CEO Toshihiro Mibe has hinted that solid-state batteries will also play a crucial role in making electric vehicles more affordable.
