Samsung says it has begun sampling solid state batteries to car manufacturers and will begin mass production of the batteries for EVs and other applications in 2027.

Last year, the company set up a pilot  line in Suwon and is using it to,refine the product and improve yields

The company says that its solid-state batteries will have an energy density of 900 watt-hours per litre which is 40% better than from its lithium-ion batteries.

As well as high energy density solid-state batteries have short charging times of around ten minutes and are lighter and safer than lithium-ion batteries.

Hyundai is also targeting 2027 for mass-production of solid state batteries and Toyota says it will start selling cars with solid state batteries in 2027-8.
