Panasonic Corp announced that deliveries of its automotive-grade lithium-ion battery cells for Tesla’ Model S electric sedan will surpass 100 million units by the end of this month.
For several years, Panasonic has built its partnership with Tesla, starting with the battery supply for Tesla’s luxury sports car, the Roadster. The relationship was extended to the battery supply for the Model S as well as collaboration on the development of next-generation lithium-ion battery cells for EVs.
The battery cell used in the Model S has been developed by Panasonic and Tesla together to achieve maximum energy density and performance. This cylindrical cell is based on Panasonic’s unique technology and optimized specifically for electric vehicle quality and life. These cells are integrated by Tesla Motors into the battery pack that powers the Model S.
Panasonic said it is strengthening the technology development and business of rechargeable battery cells for eco-friendly cars, which are expected to increase rapidly in the coming years.
