L&F Co. (066970.KQ), a KOSDAQ-listed cathode-material maker that supplies Tesla and Korea's three largest battery cell makers, said on July 7 it has launched an "ABB" (AI, big data, blockchain) smart factory at its Daegu Guji No. 1 plant, designed to automatically measure and share the carbon footprint of its products (Yonhap; ET News).
Why a cathode maker is wiring itself for carbon data
The reason this matters to an upstream supplier: under the EU Battery Regulation (the bloc's sustainability rulebook for batteries), every EV battery placed on the EU market has had to carry a carbon-footprint declaration since Feb. 18, 2025, and a machine-readable "battery passport" — storing lifecycle carbon, recycled content and supply-chain data — becomes mandatory on Feb. 18, 2027 (EUR-Lex). Because the cathode is the single largest contributor to a battery cell's carbon footprint, cell makers and automakers must pull that data from suppliers upstream. A cathode maker that cannot certify its emissions risks being designed out of Europe-bound battery programs.
What L&F actually built
Over a project begun in 2024, the company installed a life-cycle assessment (LCA) system that automatically calculates carbon emissions from raw-material input through finished-product shipment, plus a blockchain-based "data space" to share those figures with external partners (ET News). In December 2025, L&F said it became the first Korean company to pass sandbox validation with Catena-X — the automotive industry's standard data-sharing network founded in 2021 by a consortium including BMW, Mercedes-Benz, Volkswagen, BASF, ZF, Bosch, SAP and Deutsche Telekom, whose standards have since been integrated into BMW's procurement requirements as of April 2025 (ET News; Catena-X). "The core achievement is a system where data becomes trust itself," an L&F official said, naming the EU Battery Regulation as the target (ET News).
Sizing: defensive infrastructure, not a revenue line
This spending protects existing business rather than opening a new one. L&F's trailing-12-month revenue was $1.17 billion as of March 31, 2025 (PitchBook), and it is one of the few makers able to mass-produce nickel-cobalt-manganese-aluminum (NCMA) cathodes for Tesla, LG Energy Solution, SK On and Samsung SDI — Korea's three largest battery cell makers (KED Global). Nearly all of those customers ship cells into Europe, so the carbon-tracking layer touches the bulk of L&F's order book rather than a niche product.
The timing is not incidental. L&F is funding compliance infrastructure after the EV demand "chasm" that gutted its 2024 revenue (down about 59% year-on-year to 1.91 trillion won, or roughly $1.4 billion), even as its first-quarter 2026 results returned to profit on a high-nickel shipment recovery. The headline value of its 2023 Tesla supply contract was also significantly revised downward from an initial projection of $2.9 billion as volumes were rebooked (KED Global). Building auditable carbon data now is aimed at defending the customer relationships that survive the downturn.
The open question
L&F says it is still stabilizing the system across production lines and "targeting full deployment completion," without giving a date (ET News). Two markers will show whether the effort converts into retained business: whether the same LCA/blockchain layer is extended to subsidiary L&F Plus's new lithium-iron-phosphate (LFP) cathode plant — Korea's first, with 30,000 tonnes of annual capacity due to begin mass production at the end of Q3 2026 (BigGo Finance) — and L&F's next quarterly earnings, where management commentary on European order flow will indicate whether compliance readiness is translating into contracts.
