Apple has recently hired Tesla's senior engineer. They also have hired the top green battery people. It is secret but it has been going on for at least a year. The rumor is that their battery will be next gen, and unlike Tesla which has no cash and must borrow to build, Apple can literally plunk down billions in cash anywhere in the world. Their cash power , 700 million customers and #1 brand name in history makes them a formidable threat to Tesla. Similar to Apple Tv and Netflix. Just wait a year or two and see how secure those smaller companies feel.
