Honda Advances Solid-State Battery Tech With New Production Facility

The automaker's demonstration line in Japan marks a key step toward mass production, aiming to double EV range by the late 2020s.

Honda has unveiled a demonstration production facility in Tochigi, Japan, to develop all-solid-state batteries for electric vehicles.
The pilot line, set to begin operations in January 2025, is part of a $277 million investment, with nearly half funded by Japanese government subsidies.
Solid-state batteries promise to double EV driving range by the late 2020s and potentially increase it 2.5 times by the 2040s compared to current lithium-ion technology.
Honda aims to reduce battery size by 50%, weight by 35%, and cost by 25% within five years, accelerating its transition to EVs and fuel-cell vehicles by 2040.
The facility will refine manufacturing techniques, and Honda plans to launch EVs with this technology in the second half of the 2020s, while exploring potential collaborations with other automakers like Nissan.
