Elon Musk Schedules Tesla 'Battery Day' for Sept. 15Tesla's next big range increase looks set to come from battery technology, and Elon Musk plans to reveal all on Sept. 15.

Last week, Tesla announced it had managed toincrease the range of the Model S to 402 milesthanks to a range of vehicle improvements. However, the next big range increase looks set to come from battery technology, and Elon Musk plans to reveal all on Sept. 15.

AsReuters reports电池,即所谓的“天”最初planned for May, followed by a shareholder meeting on July 7. However, the coronavirus pandemic has meant both events were postponed and rescheduled (tentatively) for Sept. 15. Musk describes Battery Day as, "one of the most of exciting days in Tesla's history," but has said little about what will be revealed beyondconfirming in a tweetthat it will include a tour of the company's cell production system.

Earlier this month, Chinese battery manufacturer Contemporary Amperex Technology Co. Ltd. (CATL) revealed that it had developed a battery with a lifespan of 16 years and capable ofpowering a vehicle for 1.24 million miles. The cost of production is only 10 percent higher than the batteries being used in electric vehicles today. The one missing piece of the million-mile battery? Someone to place an order.

Seeing as Tesla is working with CATL, it seems likely that Musk is preparing to reveal some variant of this million-mile battery that will be used exclusively in Tesla's vehicles. Combine new battery tech with ongoing efficiency gains in the design of vehicle components, and we may hear a surprisingly high range being announced by Musk come September.
