Apple may start building and selling a car within the next four years. According to Reuters, the vehicle may (or may not) use self-driving technology developed by Apple, and it may (or may not) involve a “breakthrough” battery design that would be cheaper and provide longer range than current technology.
Reuters says that Apple is working on lithium iron phosphate (LFP) battery chemistry, which is cheaper than battery cells that use nickel manganese cobalt chemistry. In July of this year, Tesla announced it would switch to this chemistry for Chinese-built Tesla Model 3s by the end of 2020.
Reuters also says that Apple’s battery design “bulks up the individual cells in the battery and frees up space inside the battery pack by eliminating pouches and modules that hold battery materials.”
