Indonesia-China EV battery joint venture to start output by 2026

PT AnekaTambang

Indonesia-China EV battery joint venture is set to start operations in 2026, marking a milestone in Southeast Asia’s battery industry. PT Aneka Tambang (Antam) and CATL are leading the $5.9bn project, which will significantly expand Indonesia’s role in global EV supply chains. The Indonesia-China EV battery joint venture aims for 15GWh capacity by 2028, supporting up to 300,000 EVs annually.

A $5.9bn integrated ecosystem for battery materials

The joint venture begins with a 6.9GWh capacity, expanding to 15GWh by 2028. Additionally, officials highlighted potential integration with solar panel battery storage, raising capacity to 40GWh. Most of the investment—around $4.7bn—will fund nickel smelters, mining, and precursor plants in North Maluku. Meanwhile, the battery cell project in West Java accounts for $1.2bn of the total budget.

Indonesia’s mineral advantage meets China’s battery expertise

Indonesia holds abundant nickel, cobalt, and manganese, essential for EV batteries, but lacks lithium and advanced technology. Therefore, Antam partnered with CATL to secure the expertise and technology required. By 2026, smelting and hydrometallurgy plants, alongside a nickel-cobalt-manganese precursor facility, are expected to strengthen Indonesia’s midstream value chain. This partnership underscores a growing alignment between Indonesia’s resource base and China’s global battery leadership.

Energy independence and EV market expansion

The Indonesia-China EV battery joint venture could supply batteries for 300,000 EVs annually, potentially reducing fuel imports by 300,000 kilolitres per year. President Prabowo stated that Indonesia could reach full energy self-sufficiency within five to seven years, provided battery production grows to 100GWh annually. As a result, Indonesia is positioning itself not just as a raw material supplier but as an integrated EV hub.

The Metalnomist Commentary

Indonesia’s partnership with CATL cements its role in the global EV battery supply chain. However, success depends on infrastructure, environmental safeguards, and balancing resource nationalism with foreign investment. If executed effectively, Indonesia could become a strategic alternative to China-dominated supply routes.
