- The facility is expected to reach an annual capacity of 10 GWh and will play a key role in expanding Mazda’s range of electrified products.
The Mazda Motor Corporation today signed an agreement with Iwakuni City and the Yamaguchi Prefecture to build the "Mazda Motor Corporation Iwakuni Plant," a new facility for producing module packs using cylindrical lithium-ion battery cells supplied by Panasonic Energy Co., Ltd. Construction of the plant will begin in November, with operations scheduled to start in 2027.
