"With a global fleet of more than 1 million electric vehicles that are capable of connecting to and sharing power with the grid, Tesla's goal is to achieve the status of a power company, competing with such traditional energy providers as Pacific Gas & Electric and Tokyo Electric Power. The new "million mile" battery at the center of Tesla's strategy was jointly developed with China's Contemporary Amperex Technology Ltd and deploys technology developed by Tesla in collaboration with a team of academic battery experts recruited by Musk. Eventually, improved versions of the battery, with greater energy density and storage capacity and even lower cost, will be introduced in additional Tesla vehicles in other markets, including North America. Tesla's plan to launch the new battery first in China and its broader strategy to reposition the company have not previously been reported. "
