The SOLiDIFY consortium has successfully developed a high-performance lithium-metal solid-state battery. This innovative battery, produced in a state-of-the-art Belgian lab, features a unique electrolyte that is both cost-effective and compatible with existing lithium-ion battery manufacturing processes.
With an impressive energy density of 1070 Wh/L, this battery significantly outperforms current lithium-ion batteries, making it a promising candidate for commercialization in the electric vehicle market. The high energy density was achieved by combining a thick, high-energy-density cathode (NMC, containing nickel, manganese, and cobalt) separated from a thin lithium-metal anode by a thin solid electrolyte separator.
Importantly, this process is manageable at room temperature and adaptable to current lithium-ion battery production lines. Projected to cost less than €150 per kWh, it holds promise for affordable industrial transfer.
Additionally, the consortium overcame mechanical strength and cathode impregnation challenges to increase the cell’s charge rate to 3 hours and lifetime to 100 cycles.
The SOLiDIFY project represents a significant step forward in the development of solid-state batteries. By overcoming the hurdles associated with cost, performance, and manufacturing, the consortium has paved the way for the commercialization of this promising technology.
As the demand for electric vehicles continues to grow, the availability of high-performance, affordable batteries will be crucial in driving the transition to a sustainable transportation future.
