An interesting back of envelop math on battery tech and Apple's interest in Tesla. Apple is estimated to buy about 24,000 metric tons of batteries for 2014. Tesla is expected to put about 21,000 metric tons of batteries in their cars this year.
According to Tesla, the plant's capacity in 2020 will be higher than what the entire world produced in 2013.
A more likely explanation for Apple's conversation with Tesla might be something Apple does all the time: Sit with a potential supplier and discuss payment in advance as a way to secure supply of a critical component.
