Solid-state batteries could be safer and more energy-dense than today’s lithium-ion technology, but finding materials that allow ions to move quickly through solid electrolytes has been difficult.

Earlier this month, a little-known Finnish startup shocked the world when it claimed to have beaten Toyota, Samsung, LG Energy, Quantumscape and any number of Chinese automakers at commercializing the ...

VTT testing says Donut Lab’s “solid-state” battery likely matches lithium-ion; energy density measured at 298 Wh/kg, claims ...

A new manufacturing technique is helping to overcome some of the major hurdles in developing more reliable and durable all-solid-state batteries. Combining a controlled sintering step with precise ...

What if the future of energy storage wasn’t just an incremental improvement but a complete reimagining? Solid-state batteries, long considered the holy grail of energy technology, could be the key to ...

The Donut Lab solid-state battery was heated to the boiling point of water. Here’s what happened next.

A Swiss research team has developed a low-temperature sintering and interface-coating process that significantly improves the durability of argyrodite-based solid-state batteries. The approach ...
