A groundbreaking development in solid-state battery technology has produced a new battery with significantly higher energy density than current lithium-ion batteries. Researchers in Europe have successfully created a solid-state battery with an energy density of 1,070 Wh/L, surpassing the current 800 Wh/L benchmark.
The prototype battery, developed by a consortium of 14 European partners in the SOLiDIFY project, was produced using an innovative manufacturing process that is compatible with existing lithium-ion battery production lines. This method is not only cost-effective but also enables the production of solid-state lithium-metal batteries that are commercially viable for electromobility.
One of the key advancements in the battery’s design is the use of a solid-state electrolyte that changes phase from liquid to solid. This breakthrough, developed by France-based tech company Solvionic, allows for the application of thin electrolyte layers on cathodes, resulting in higher volumetric energy densities and the creation of compact battery cell stacks.
The introduction of a thin lithium-metal anode, together with a sufficiently thin solid electrolyte separator, contributes to the battery’s higher energy density. This achievement was made possible through the careful evaluation and optimization of new materials and advanced coatings provided by the consortium partners.
The new solid-state battery also addresses safety concerns associated with traditional lithium-ion batteries. It exhibits reduced flammability due to its thermally stable cell and the use of nanometer-thin protective coatings. Additionally, the battery’s cathodes have been developed with reduced cobalt content, resulting in a lower environmental impact while maintaining higher capacity.
The successful development of this high-energy-density solid-state battery represents a significant breakthrough in the field of battery technology. It holds the potential to revolutionize various industries, including electric vehicles, by providing longer-lasting and more efficient power sources. As researchers continue to optimize the manufacturing process and overcome challenges, the widespread adoption of solid-state batteries could soon become a reality.
