CATL and CarbonScape partner to scale biographite for EV batteries

CATL, the world's largest EV battery maker, has invested in CarbonScape to commercialize biographite, a battery-grade graphite made from forestry by-products. The partnership aims to bring production online by the end of the decade, targeting cost parity with conventional graphite and a carbon-negative footprint. CATL will provide manufacturing expertise and board representation to help scale the technology. This deal addresses a key bottleneck in battery supply chains: graphite is the largest material by volume in EV batteries, yet most supply is oil-based. CarbonScape's process uses renewable forestry residues instead. If the technology reaches gigafactory scale, it could reduce the carbon footprint of battery production and diversify supply away from traditional mined graphite. The article notes CATL's investment includes equity incentives tied to successful commercial deployment.

CATL putting money into biographite is interesting. Graphite is the biggest material in a battery by volume and most of it comes from oil or mining. If CarbonScape can really hit cost parity with a carbon negative process, that changes the supply chain math for EVs.

The article says they aim for commercial production by the end of the decade. That is a long runway. I would like to see more detail on the current demonstration scale and what milestones they have to hit before CATL opens its facilities for validation.

Biographite from forestry residues sounds promising but the timeline is vague. 'End of the decade' is 4 years out. What is the current output in tonnes per year? Without that number it is hard to judge if this is a real scale up or just a pilot extension.

The article mentions equity incentives tied to commercial deployment. That is a smart structure. It aligns both companies on actual production milestones rather than just R&D. If CATL is putting board seats and manufacturing facilities behind this, they see a path to volume.

This could matter for EU and US battery regulations that require local sourcing and lower carbon footprints. Biographite from forestry residues might qualify under the EU Battery Regulation's carbon footprint rules. But the article does not say where the forestry residues come from or how the carbon accounting works.

Forestry by-products as feedstock is interesting but the supply chain logistics matter. Are they using sawmill waste, logging slash, or something else? The cost and consistency of that feedstock will determine whether this can actually hit the claimed cost parity.
