Breakthrough in Battery Technology: European Researchers Develop High-Energy Solid-State Battery

A European research consortium has made a significant breakthrough in battery technology by developing a prototype solid-state battery with a remarkable energy density. The “SOLiDIFY” consortium, comprising 14 European research institutes and partners, has successfully created a lithium-metal battery with a solid electrolyte that offers 20% higher energy density than current lithium-ion batteries.

The team achieved an impressive energy density of 1,070 Wh/L in a pouch cell, surpassing the 800 Wh/L energy density typically found in standard lithium-ion batteries. This major advancement was made possible through the use of a thick cathode made of nickel, manganese, and cobalt (NMC), combined with a thin lithium-metal anode and a solid-state electrolyte separator.

The research consortium utilized Solvionic’s solid-state electrolyte, which underwent a phase change from liquid to solid. This transformation enabled the application of thin electrolyte layers, resulting in compact battery cell stacks and higher volumetric energy densities. The manufacturing process created by the consortium operates at room temperature and can be seamlessly integrated into existing lithium-ion battery production lines.

Not only does this new battery technology exhibit superior energy density, but it also offers improvements in charging time and thermal stability. The cell’s charging time has been reduced to a mere three hours, while thermal stability has been enhanced when compared to traditional lithium-ion batteries.

While this prototype solid-state battery shows immense promise, the consortium is already looking to scale up the technology in the next phase. They aim to make this groundbreaking battery technology accessible on a larger scale, opening up possibilities for a multitude of applications, ranging from electric vehicles to renewable energy storage.

Although the cost of the batteries is estimated to be around €150 ($166)/kWh, which is higher than current lithium iron phosphate and high-nickel NMC batteries, the Swiss Federal Laboratories for Materials Science and Technology (Empa) believes this cost is still viable for affordable technology transfer in the industry.

The development of this high-energy solid-state battery is a significant step forward in addressing the growing demand for more efficient and powerful energy storage solutions. With continued research and advancements, this technology could potentially revolutionize various industries, leading to a greener and more sustainable future.
