Sustainable synthetic graphite anodes
Vianode anode materials for lithium-ion batteries enable electrification, which is key to reduce emissions in the power system and transportation sector by:
- Enabling electrification of transportation.
- Facilitating the transition to variable renewable energy sources, such as wind and solar.
- Facilitating an efficient grid that requires less investments.
- Supporting energy efficiency through smart applications.

The power system and transportation sector together account for about 40% of total GHG emissions, according to McKinsey and World Economic Forum.
Today, anode materials are one of the largest greenhouse gas emission contributors in battery production. Most synthetic graphite anode materials have a footprint of 20 – 30 kg. CO2 equivalents per kWh, which can account for a fourth of the battery production footprint.
Vianode anode materials have more than 90 percent lower embedded CO2 emissions compared to conventional production and paves the road to low-footprint batteries.
This is made possible thanks to specialised and proprietary know-how in high temperature, closed production processing systems, lower energy consumption and access to clean renewable energy from hydro power at our production site in Norway.
Better batteries that last longer
Synthetic graphite, the most common anode material, has exceptional cycle life compared to other anode materials. In addition to enhancing product quality, improved cycle life is also sustainable:
- It enables increased lifetime of batteries and electric vehicles (EV), supporting faster EV adoption and a functioning second-hand EV market
- It will assist critical infrastructure innovations, such as vehicle-to-grid or vehicle-to-home applications, necessary to support global electrification
Cleaner production technology
Vianode's production processes use innovative, closed furnace technology, which implies:
- Reduced energy consumption (approximately 50% reduction in the graphitisation part of production compared to conventional production)
- Minimal other direct emissions, including dust and sulphur dioxide (SO₂)
- Enabling efficient energy recovery processes to facilitate district heating, for example
Access to renewable energy
Despite the reduced energy consumption, production of synthetic graphite is still energy intensive. Vianode's production is based on electricity from renewable hydro power, reducing the greenhouse gas footprint as low as possible.
Recycling throughout the process
Recycling is also an integral part of Vianode's business model and we have a circular approach to our production. This means that we recycle by-products throughout the production process.
We also invest in R&D to replace our raw materials with recycled graphite from production scrap or end-of-life batteries in the long-term. Vianode has successfully recycled graphite from used batteries back into new battery grade graphite with similar performance as virgin graphite.
How Vianode addresses the UN Sustainable Development Goals (SDGs)
Vianode anode materials drive electrification by enabling low-footprint batteries. Vianode believes SDGs 7, 8, 9, 12 and 13 most accurately sums up our impact.
Affordable and clean energy
Vianode facilitates more renewable energy production from variable sources, such as wind and solar, by enabling energy storage both in front and behind the meter. In addition, energy storage reduces grid investment needs through bottleneck relief, peak shaving and off-grid solutions.
Decent work and economic growth
Vianode plans to recruit 300 additional employees by 2026. In 2030, we estimate to have created about 1,000 new direct jobs and many more indirect jobs, for a high variety of skillsets. Vianode promotes ethical work conditions with a focus on health and safety.
Industry, innovation and infrastructure
Vianode has developed an innovative technology with significant sustainability benefits, that will support the fast-growing battery industry. With our new technology, we set the stage for further innovation on virgin and recycled anode materials for batteries.
Responsible consumption and production
Vianode produces synthetic graphite anode materials with more than 90% lower embedded emissions than conventional production, partly because of lower consumption of energy and input materials. Our main raw material is coke, which is a waste product from oil refineries that Vianode processes into a key material for the green transition. That’s until we can get enough volumes of graphite from recycled batteries, which our R&D team has proven the feasibility of.
Vianode enables batteries which drive electrification and reduce emissions in the power system and the transportation sector, which together account for about 40% of total GHG emissions. The faster the world scales up a sustainable battery industry, the more time we have to reduce emissions in hard-to-abate sectors.
