Panasonic Expanding Customer Base
Panasonic’s cylindrical batteries have predominantly been utilized in Tesla EVs. Recently, the company has been focusing on developing large, high-capacity 4680-type cylindrical cells, which could potentially be used in Subaru and Mazda EVs in addition to Tesla vehicles.
While specific details of the partnership have not been disclosed yet, both companies have mentioned that they will release more information at the appropriate time.
The negotiation process between Panasonic and Mazda mirrors the discussions Panasonic had with Subaru, resulting in a partnership for the supply of cylindrical automotive lithium-ion batteries.
Mazda and Subaru are likely interested in Panasonic’s advanced high-capacity cylindrical batteries, such as the upcoming 4680-type cells. Panasonic plans to launch the first 4680-type batteries between April and September 2024. Aside from the larger cells, Panasonic also offers smaller types like 1865 and 2170, though it’s the cylindrical design that stands out as the key focus.
Initial production of Panasonic’s 4680-type batteries in Japan may cater to Mazda and Subaru, while U.S. production could serve Tesla, prompting other manufacturers to place orders to qualify for local supply incentives.
