Samsung's 'dream battery' lands 2027, galaxy ring 2 poised to lead the charge

Samsung SDI is officially aiming to mass-produce all-solid-state batteries by late 2027, a move that could fundamentally reshape the future of mobile power and beyond. The announcement, made public today in the JoongAng Daily, signals a significant acceleration in the development of this next-generation battery technology – and potentially a game-changer for your next Galaxy device.

Solid-state batteries: a leap beyond lithium-ion

For nearly a decade, Samsung has been pursuing solid-state battery development, initially teasing a ‘dream battery’ for future Galaxy smartphones back in 2017. While 2019 and 2019 passed without a revolutionary phone, today’s news suggests the company is finally hitting its stride. The technology promises a dramatic shift – offering significantly higher energy density, faster charging speeds, and drastically improved safety profiles compared to traditional lithium-ion batteries.

Kim eun-ha's vision: days of battery life

According to Samsung SDI Vice President and Head of Production Development Group, Kim Eun-ha, initial testing with potential customers in the EV and robotics sectors has yielded overwhelmingly positive results. “We are conducting sample performance evaluations with multiple global customers who have responded positively about [the batteries’] energy density and safety,” she stated. This suggests a genuine market demand for the technology, driving Samsung to prioritize mass production.

Beyond the galaxy: evs and robotics

But the ambitions extend far beyond smartphones. Samsung’s “dream battery” is targeting electric vehicles (EVs), robotics, and wearable devices – starting with the Galaxy Ring 2. Industry insiders believe this ring will be the first gadget to incorporate the new technology, offering users the tantalizing prospect of days-long battery life.

The price of progress

Of course, the cost factor remains a significant hurdle. Solid-state batteries currently command a premium, with prices hovering between $400 and $600 per kilowatt-hour – compared to roughly $81 per kilowatt-hour for conventional lithium-ion. However, Samsung anticipates that mass production will drive costs down, though the Galaxy Ring 2 will likely come with a higher price tag than previous models. “Solid-state battery production costs are inevitably high in the early stages,” Eun-ha explained.

A galaxy s28 in sight?

While the Galaxy S27 series isn’t expected to feature the innovative battery, the Galaxy S28, slated for launch early 2028, could be the first flagship device to truly unlock the potential of solid-state power. Expect a battery that can genuinely last for days on a single charge – a prospect that, frankly, is starting to feel less like a dream and more like a reality.
