So what are hollow batteries? Basically if you’ve ever charged a phone or a laptop, you’ll know that it sometimes can get a bit warm. This is natural, but obviously if the battery can stay cool, it would be more efficient. With these alleged hollow batteries, apparently airflow is not an issue which in turn allows it to cool better, and also reduce the need to install separate cooling devices.
It also helps ensure the battery doesn’t overheat and explode, which obviously is a big no-no when it comes to cars. These hollow batteries are said to be made by a small Korean company whose employee count is around 20. The company’s name was not mentioned due to an NDA, but MacRumors, after some digging, have speculated it could be a company called Orange Power.
Never heard of them? Don’t worry, we haven’t either, but assuming this is true, it looks like Apple’s work on their rumored Project Titan electric vehicle is progressing rather nicely.
