Samsung recently made a splash in the industry by showcasing its recent advancements in battery technology, especially related to solid-state batteries.

At the SNE Battery Day 2024 expo in Seoul, South Korea, the company revealed that its pilot solid-state battery production line is now fully operational.

“We built a pilot line last year to mass-produce all-solid-state batteries by 2027,” said Samsung SDI, as reported by The Elec.

Moreover, the battery’s initial batches have already been delivered to EV manufacturers for testing.

“We supplied samples to customers from the end of last year to the beginning of this year and are receiving positive feedback,” Samsung SDI stated.

Notably, these batteries could power electric vehicles with a 600-mile range, charge in 9 minutes, and have a lifespan of 20 years.

Some interesting details:

”Samsung’s oxide solid-state battery technology boasts an energy density of 500 Wh/kg, nearly double the 270 Wh/kg density of mainstream EV batteries.”

The article doesn’t say what kind of battery chemistry they are using, but at least the gravimetric energy density is impressive.

That's great to hear. Gravimetric energy density is the most important factor for EVs, I'm glad it sounds like it's an improvement.

At the moment, these batteries will be available in some really expensive applications, but I guess eventually they will become available in more common products as well. Hopefully, one day solid state batteries will be about as common as current NMC batteries are.
