Samsung is going to start using solid-state batteries for its wearables soon, as these can deliver higher energy density as well as more freedom to design them in weird shapes. That’s because they use a solid electrolyte, unlike traditional lithium-ion batteries which have liquid electrolytes. Thus, solid-state batteries come with less of a fire risk, and Samsung knows a thing or two about battery fires so it would obviously want to do all it can to avoid them.
This information comes from a new report out of Korea, which says Samsung’s first product with a solid-state battery will be a Galaxy Ring launching in the fourth quarter of this year – that’s probably the Galaxy Ring 2 or Galaxy Ring 3 if the Ring 2 launches sooner than that.
Then, solid-state batteries will be applied to earbuds in the fourth quarter of next year, and finally smartwatches in the fourth quarter of 2027. There’s no word about solid-state batteries for smartphones just yet out of Samsung Electro-Mechanics.
Unfortunately, the use of a solid-state battery in the next Galaxy Ring might make it even more expensive than its predecessor, which wasn’t cheap to begin with. That’s because the manufacturing cost for these batteries is much higher than for traditional ones.
