“Strange, if true,” Musk said of those suggestions. He went on to add Tesla already uses iron-phosphate batteries in vehicles it produces at its Shanghai Gigafactory, and said a monocell design is “electrochemically impossible” as the resulting battery couldn’t produce a high enough max voltage to be useable. “Maybe they meant cells bonded together, like our structural battery pack?” he said. The report also mentioned the possibility of Apple adding LiDAR sensors to the vehicle. If you’ve been following Musk for a while, you’ll also know he has called LiDAR a “fool’s errand.” In other words, it’s safe to say Musk is unimpressed by the rumors.
In any case, we’ve reached out to Apple for comment on Musk’s tweets. The company is unlikely to respond, but we’ll let you know if we hear back.
