An anonymous reader quotes a report from Bloomberg: Apple Inc. is in talks to buy long-term supplies of cobalt directly from miners for the first time, according to people familiar with the matter, seeking to ensure it will have enough of the key battery ingredient amid industry fears of a shortage driven by the electric vehicle boom. The iPhone maker is one of the world's largest end users of cobalt for the batteries in its gadgets, but until now it has left the business of buying the metal to the companies that make its batteries. The talks show that the tech giant is keen to ensure that cobalt supplies for its iPhone and iPad batteries are sufficient, with the rapid growth in battery demand for electric vehicles threatening to create a shortage of the raw material. About a quarter of global cobalt production is used in smartphones. Apple is seeking contracts to secure several thousand metric tons of cobalt a year for five years or longer. Its first discussions on cobalt deals with miners were more than a year ago, and it may end up deciding not to go ahead with any deal, another person said.
