“Solid-state batteries—which pack more energy into each unit of volume than current batteries and will stretch the range of electric vehicles—have long felt just out of reach. 

But they are getting close, and recent progress helps to clarify when the first models may arrive.

Samsung SDI said in March that it will produce solid-state batteries for use in high-end vehicles by 2027. The vehicles would be able to travel more than 600 miles before needing to be recharged. Samsung, based in South Korea, didn’t say which automakers would use the battery, but the company has relationships with GM, Hyundai and Stellantis.

A range of 600 miles would be roughly double the ranges of today’s most popular models.”
