Analysis of Tesla's upcoming battery, the 4680 cell. "The enlarged, cylindrical 4680 cell, which Tesla first teased at its Battery Day last September, brings its own sky-high hopes and challenges: If Tesla can pull off in-house, vertically integrated battery manufacturing, and the cell performs as advertised, the 4680 could fuel Musk's dreams to build millions of EVs a year around the world. Tesla's goals include boosting driving range by more than 50 percent -- 16 percent of that due to the 4680's newfound punch -- while halving battery costs and bringing a $25,000 Tesla to showrooms. Tesla continues to dominate EV sales in America, but its seemingly insurmountable lead in driving range is under assault. The Arizona-built Lucid Air sedan, the work of Musk's former Model S chief engineer, has demonstrated it can travel up to 517 miles, a lofty record for any EV. Tesla's best, the Model S Long Range, is EPA-rated for 405 miles."
