Lithium-ion batteries are a key technology for e-mobility.

HiQ-CARB

The HiQ-CARB project team has set itself the goal of developing more sustainable carbon black additives for lithium-ion batteries.

Supported by EIT RawMaterials

HiQ-CARB –
what is it about?

Among other things, carbon black additives are an important factor in battery performance – but commercially available carbon black has a high carbon footprint.
At the laboratory scale, environmentally friendly alternatives such as acetylene carbon black with a low carbon footprint and resource-efficient carbon nanotubes already exist.

To provide the fast-growing battery industry with affordable, sustainable and high-quality carbon additives, these alternative carbon blacks are being upscaled, combined and commercialized by the HiQ-CARB consortium. The performance of the upscaled „greener“ carbon blacks will be evaluated at laboratory and pilot scale, as will their environmental footprint through a sophisticated life cycle assessment.

Press release on the achievements after first half of the project work

Upscaling in progress!

By the end of 2021, a major upscaling success has already been achieved: the Carbon Nano Tube synthesis has been improved and brought to batch size > 1 t. And wet-beaded acetylene black production was also ramped up to a batch size of > 80 t. A great success in...

Stepstone for sustainable batteries – greener carbons

Lithium-ion batteries require in addition to lithium ions a number of sophisticated functional materials for their performance. Some of them sound rather unspectacular: conductive additives. In fact, conductive additives like carbon black or carbon nanotubes are a...

IN A NUTSHELL

The HiQ-CARB project aims to provide the European industry with more sustainable and hiqh-quality carbon additives for advanced lithium-ion batteries.

MOTIVATION/AIMS

Lithium-ion batteries with high energy density and long lifetime have been regarded as promising energy storage and conversion devices for applications in electric vehicles and smart grids. The European Green Deal and various supporting actions aim to exploit the employment, growth and investment potential of batteries. A competitive manufacturing value chain in Europe is to be created – last but not least to foster green battery technologies with improved environmental performance.

TECHNOLOGIES

Carbon black is usually produced with high energy and material input. HiQ-CARB is replacing the conventional conductive carbon black with a new and much more environmentally friendly high quality acetylene carbon black. This contributes significantly to improving the environmental footprint. Already commercialized standard carbon nanotubes (made from a renewable bioethanol feedstock) are replaced by thinner carbon nanotubes. This results in a lower amount of carbon materials for the same or even better battery performance and improved resource efficiency.

SUSTAINABILITY ASPECTS

Lithium-ion batteries are essential for electric vehicles, portable electronic devices, or a variety of other applications where renewable energy is stored and delivered. Sustainable, cost-efficient and hiqh-performance conductive additives are required for all these battery applications.

PARTNERS

The project consortium includes the leading materials manufacturers Orion Engineered Carbons and Arkema as well as the innovative cell manufacturer Customcells. Application-oriented battery R&D competences and a life cycle assessment are provided by Fraunhofer ISC, Aalto University and the University of Bordeaux.

PRODUCTS

To provide sustainable, high-quality carbon additives to the rapidly growing battery industry, Orion’s Acetylenes Black and Arkema’s resource-efficient carbon nanotubes are being used, combined and commercialized on a larger scale.

Reduce CO2

reduce co2 emissions –
we are working on it

If more and more batteries are needed for the energy and mobility transition, then we must also do more for sustainability and climate protection here.

HiQ-CARB wants to significantly reduce carbon dioxide emissions in the production of conductive additives for batteries – and thus make an important contribution, because the production of conventional conductive additives accounts for a large part of the carbon footprint of batteries.
