Earlier this year, it was reported that Apple was holding discussions with cobalt miners to secure a long-term supply of the metal. Notably, cobalt is used in the production of lithium-ion batteries. And while Apple could simply want more control over its supply chain, there’s another possibility, too.
As we’ve seen, Apple likely wants to produce as many of its own components as possible. There’s no reason that can’t expand to batteries — particularly with its recent battery-related controversy. While this is purely speculation, an Apple-designed and produced battery could allow the company finer control over a component that’s caused it trouble. And it could fit into Apple’s larger plans to be its own supplier.
