Imec Doubles Its Solid-State Battery Energy Density

They now reach 400 Wh/liter, enough for a 100 kWh EV battery pack.

EV fans eagerly wait for solid-state batteries to become commercially viable. Not for any sort of technology interest – at least not alone – but rather out of the benefits they will offer to electric cars. Imec is one of the research institutes trying to bring them to the market. And they recently announced doubling their solid-state batteries’ energy density from 200 Wh/liter to 400 Wh/liter.

The main innovation Imec proposes is a solid nanocomposite electrolyte that can be applied first as a liquid, through wet coating. It later solidifies and keeps elastic, something that is considered vital for solid-state batteries long term durability.

Imec claims the 400 Wh/liter and 0.5C (2 hours) charging speeds are “a record combination for a solid-state battery”, but the company believes there is a lot of room for improvement. 

It expects, for example, to reach 1,000 Wh/liter and a 2C (half an hour) to 3C charging speed by 2024.

The main advantage the new technology offers – according to Imec – is the room for improving the range of vehicles by achieving a higher power density. But solid-state batteries are also said to be more resistant and cheaper to build.

Imec, the world-leading research and innovation hub in nanoelectronics, energy and digital technologies and partner in EnergyVille, has fabricated an innovative type of solid-state Li-ion battery achieving an energy density of 200 Wh/liter at a charging speed of 0.5C (2 hours). This battery is a milestone on our roadmap to surpass wet Li-ion battery performance and reach 1000Wh/L at 2C by 2024. With this clear performance engineering path, imec’s battery technology is ready to become a contender to power tomorrow’s fast-charging, long-haul vehicles.
