Apple is aiming to have its own self-driving car on the market by 2024 that could include a new battery design optimized for longer ranges, sources familiar with the plans told Reuters.

Two unnamed sources told the news service that Apple’s so-called Project Titan aims to have a product ready for consumers within just a few years that would feature Apple’s own design for a battery which one source said would “radically” reduce the cost of automobile batteries.

Central to the project is the development of a “monocell” battery meant to save space with a more efficient design, allowing the company to create a potentially longer-lasting device. One source also indicated that Apple was pursuing a material known as lithium iron phosphate in the hopes of developing batteries with lower risks of overheating.
