The battery event, which Musk has touted as being “one of the most of exciting days in Tesla’s history”, had previously been scheduled in May while the shareholder meeting was due to take place on July 7. The Battery Day event will include a tour of the company’s cell production system, Musk tweeted, without elaborating. Tesla and China’s Contemporary Amperex Technology Ltd (CATL) <300750.SZ> are jointly developing batteries designed to last a million miles of use and enable electric Teslas to sell profitably for the same price or less than a gasoline vehicle, people familiar with the plans have said.
