Volvo Cars has signed agreements with its two primary global battery suppliers — China-based CATL and South Korea's LG Chem — to implement blockchain-based traceability for cobalt used in electric vehicle batteries. The initiative is scheduled to launch this year and aims to enhance transparency across the supply chain for a material considered critical to battery production.

Volvo Cars is positioned to become the first automaker to deploy global cobalt traceability using blockchain technology. The system will track cobalt incorporated into lithium-ion batteries installed in Volvo's electric vehicles, recording data about the material's origin and its movement through each stage of the supply chain.

The company plans to leverage blockchain to create an immutable traceability record spanning from the cobalt source through the battery supply chain, giving customers greater assurance that materials in Volvo electric vehicles are responsibly sourced.

How Blockchain Supports Supply-Chain Transparency

Blockchain technology establishes a shared data network among supply-chain participants, enabling authorized parties to record and access relevant information. Because blockchain entries are designed to resist undetected alteration, the technology can bolster the reliability of data concerning the origin and handling of raw materials.

Cobalt Sourcing as an Industry Challenge

Responsible cobalt sourcing has emerged as a significant sustainability concern for automakers as demand for electric vehicles and lithium-ion batteries continues to grow. Cobalt is a key component in multiple battery chemistries, and persistent concerns about its sourcing have pushed manufacturers to seek deeper visibility into where and how the material is extracted and processed. The Democratic Republic of the Congo accounts for the majority of global cobalt production, and reports from organizations such as Amnesty International and the OECD have documented human rights issues — including child labor — at artisanal mining sites in the region, intensifying pressure on companies to verify the provenance of their battery materials.

Volvo Cars stated that the initiative forms part of its broader effort to build an ethical and transparent raw-material supply chain. Martina Buchhauser, the company's head of procurement, said Volvo has long prioritized responsible sourcing and views blockchain as an opportunity to enhance traceability and mitigate supply-chain risks through closer collaboration with suppliers.

Technology Partners and Implementation

The initiative involves multiple technology and responsible-sourcing organizations working alongside Volvo's battery suppliers.

For CATL's supply chain, blockchain technology is being operated by Circulor and Oracle following a successful pilot program conducted earlier in the year. The system is designed to provide greater visibility into cobalt as it moves through the relevant supply-chain stages.

For LG Chem, the Responsible Sourcing Blockchain Network is collaborating with responsible-sourcing specialists RCS Global and IBM to deploy comparable technology across the supplier's supply chain. The separate initiatives are intended to deliver traceability while promoting responsible sourcing practices among all participating companies.

Volvo's Broader Electric Vehicle Strategy

The blockchain initiative coincides with Volvo Cars' accelerated transition toward electrified vehicles. The company recently introduced the XC40 Recharge, its first fully electric model under the Recharge product family, as it prepares to expand its electric vehicle lineup.

Volvo Cars has set a target of having fully electric vehicles account for half of its global sales by 2025, with the remainder expected to come from hybrid models. The automaker has also established a goal of reducing carbon emissions per vehicle by 40 percent by the same year.

By connecting battery-material sourcing with blockchain-based traceability, Volvo aims to address supply-chain transparency in tandem with its wider electrification and emissions-reduction objectives. The initiative also aligns with emerging regulatory expectations, as the European Union has been developing battery due-diligence requirements that would obligate manufacturers to demonstrate responsible sourcing of raw materials.

The move underscores how automakers are increasingly looking beyond vehicle design and powertrain technology to improve the sustainability of materials used in electric cars. Greater visibility into cobalt sourcing could equip manufacturers with stronger tools for identifying supply-chain risks and demonstrating responsible procurement practices.

For Volvo, the initiative represents an effort to pair its electric vehicle expansion with greater accountability for the raw materials underpinning that transition. As demand for battery-powered vehicles grows, technologies capable of tracking critical materials may become an increasingly integral component of efforts to build more transparent and sustainable automotive supply chains.
