Battery technology is constantly evolving, and the latest advancement comes from Panasonic, which revealed a prototype of its new 4680 battery cell. Automotive News reports that the advanced-technology battery is due to power future Teslas, saying the 4680 batteries will have five times the storage capacity of current Tesla battery packs and will cost 50 percent less to build.
This is the first time Panasonic has unveiled the 4680 battery. Tesla’s earnings report issued earlier this month said it was testing battery packs using the 4680 cells. Panasonic constructed a test line for the new format earlier this year. 4680 refers to the battery’s dimensions: 46 millimeters (1.6 inches) wide by 80 mm (3.1 in) tall. Tesla claims that there will be a 100-fold increase in battery production by 2030 thanks to the new battery type, and that the new cell design produces six times the power of current cells.
Tesla is one of the only automakers using cylindrical cells, and the additional energy capacity of the new 4680 cell isn’t magic, it’s simply a lot larger than the current ones Tesla employs. On a purely volume basis, the 4680 is 5.5 times larger than the 2170 cells currently used in the Model 3 and Y battery packs and 8.0 times larger than the 18650 cells used in the Model S and X (the 18650 is slightly larger than a typical AA battery).
The head of Panasonic’s battery operations, Kazuo Tadanobu, said at the meeting, “We have developed this because of the strong desire of the other party, and we think this can only lead to stronger ties.” Panasonic has a battery manufacturing plant in Nevada, supplying the Tesla Gigafactory. According to Electrek, Tesla claims the first vehicles with the 4680 battery cells will be delivered next year. Tadanobu also said that Panasonic does not intend to build cheaper lithium-iron phosphate (LFP) batteries for standard-range Teslas, even though Tesla’s report said the company plans to start using those in its “standard range” vehicles worldwide.
Along with building the 4680 batteries for Tesla, Panasonic will also supply batteries to American electric startup Canoo, which recently announced an agreement with the Japanese electronics corporation. The batteries will power the Lifestyle Vehicle that Canoo predicts will begin production in the fourth quarter of 2022, with Dutch contractor VDL Nedcar building the vanlike vehicle for the European and American markets. Canoo said they chose the Panasonic batteries—which will not be the Tesla-specific 4680 format—for their proven reliability. Canoo is claiming a range of 250 miles from a 80.0-kWh battery, with the base panel van version starting at $34,750.
