At the cutting edge of battery technology, Imec, a leading research centre, has unveiled a major breakthrough in electric vehicle (EV) power systems. In collaboration with 13 European partners under the H2020 SOLiDIFY project, Imec has developed a lithium-metal solid-state battery boasting an impressive energy density of 1070 watt-hours per litre (Wh/L). This development outpaces current lithium-ion batteries, which max out at around 800 Wh/L, and offers exciting possibilities for the future of EVs.
Why This Matters for Car Leasing
As electric vehicles become more popular, potential customers are prioritising longer ranges and quicker charging times. The new solid-state battery from Imec addresses these consumer demands by offering a much higher energy density than traditional batteries, meaning more energy can be stored in the same amount of space. This could translate into EVs with longer driving ranges, a crucial selling point for car leasing firms aiming to offer cutting-edge, efficient vehicles to their clients.
The Advantages of Solid-State Batteries
Standard lithium-ion batteries use a liquid electrolyte, which carries some safety risks, including leaks and even fire hazards. Solid-state batteries, however, replace the liquid with a solid material, significantly reducing these risks while also providing better energy efficiency and thermal stability. Until now, the main challenge for solid-state batteries has been the cost of production. But Imec's innovation introduces a cost-effective solution that aligns with existing lithium-ion production lines, making it more feasible for mass production.
Game-Changing Energy Density and Efficiency
The standout feature of Imec’s battery is its exceptional energy density. Thanks to advanced materials and innovative designs such as a thin lithium metal anode and a solid electrolyte separator the battery achieves 1070 Wh/L. For electric vehicles, this translates into more powerful performance and extended range, both of which are highly attractive to drivers.
Affordable, Scalable Manufacturing
One of the most significant barriers to solid-state battery adoption has been cost. Imec’s battery production process, however, is both affordable and scalable. The new method can be implemented in existing lithium-ion battery factories, meaning manufacturers won’t need to invest heavily in new equipment. Even better, the battery is projected to cost less than €150 per kilowatt-hour (kWh), making it an economically viable option for widespread use in electric vehicles.

Improved Safety and Sustainability
In addition to enhancing energy efficiency, this new battery offers improved safety, reducing the risk of overheating or fire thanks to its solid-state design. The use of cobalt-lean NMC cathodes also addresses environmental concerns, as it reduces the reliance on cobalt, a material linked to significant ethical and environmental issues in its sourcing.
What This Means for the Future of EV Leasing
As Imec and its partners work on scaling up production, the potential for these batteries in the EV market is clear. With longer ranges, faster charge times, and improved safety, leasing companies could soon offer electric vehicles that appeal to a broader audience. As battery technology continues to advance, the cost of leasing EVs could become more competitive, giving consumers even more reason to make the switch.
