Samsung sampling solid state batteries

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.
