According to a Financial Times’ report on Monday, Toyota’s long-awaited solid-state batteries are to be ready by 2027 or 2028.
The company is working on the batteries, which, according to the Financial Times, should have a range of 1,200 km, twice as long as Toyota’s current range.
The solid-state batteries are also to lower Toyota’s EV charging time to 10 minutes.
The batteries are costly and hard to manufacture. Challenges with the batteries include their heightened sensitivity to moisture and oxygen, along with the mechanical pressure required to prevent dendrite formation—metal filaments causing short circuits.
According to Toyota’s comment to FT, the hardest part is the battery assembly. The cathode-anode cell layers of a battery should be stacked quickly and precisely, as they are easily damaged.
