As part of this collaboration, Panasonic Energy will produce and supply cylindrical lithium-ion batteries at its Suminoe factory in Osaka from fiscal 2027, 1 and at the new jointly established lithium-ion battery factory in Oizumi, Gunma Prefecture from fiscal 2028. 1 Subaru plans to install these batteries in its BEVs.
Panasonic Energy’s renovated plant in the western prefecture of Wakayama will serve as the main factory for producing the 4680 cells, which the company says have five times the capacity of its smaller 2170 cylindrical batteries.
Tokyo and Osaka, Japan, September 6, 2024 - Subaru Corporation (“Subaru”) and Panasonic Energy Co., Ltd. (“Panasonic Energy”), a Panasonic Group Company, today announced plans to prepare for the supply of automotive lithium-ion batteries and joint establishment of a new battery factory in Oizumi, Gunma Prefecture, Japan.
Panasonic Energy will supply its next-generation cylindrical automotive lithium-ion batteries for the battery electric vehicles (BEVs) Subaru plans to produce from the latter half of the 2020s. This follows their conclusion of a basic cooperative agreement and reflects their aim of establishing a medium- to long-term partnership.
Panasonic, one of Tesla’s long-standing battery suppliers, is currently building its second U.S. battery plant in Kansas that is set to start production next year, in addition to one in Nevada.
