Indonesia Battery Ecosystem Project Moves Forward With New Chinese Partnership

Aneka Tambang

The Indonesia battery ecosystem project is moving into a new phase with a fresh Chinese partnership. Antam, Industri Baterai Indonesia, and HYD Investment signed a framework agreement to develop an integrated battery ecosystem in Indonesia. This follows the exit of LG Energy Solution in 2025. As a result, the Indonesia battery ecosystem project remains alive and strategically important.

The change in partners matters because the project scale remains significant. Antam said the planned investment value is around $5-6 billion. A joint feasibility study will now define the next steps. Therefore, the Indonesia battery ecosystem project is shifting from partner transition into renewed execution planning.

HYD brings a strong industrial base to the table. The consortium includes Zhejiang Huayou Cobalt, EVE Energy, and Daaz Bara Lestari. That mix adds processing, battery, and investment capability. Consequently, the project gains a broader foundation across the battery value chain.

Indonesia Nickel Battery Chain Expands From Ore to Cells

The Indonesia nickel battery chain is central to this project’s logic. Planned facilities include an RKEF plant with 100,000 t/yr of nickel metal equivalent capacity. The project also includes an HPAL plant with 50,000 t/yr of nickel metal equivalent capacity. Therefore, upstream and midstream nickel conversion remain core pillars.

The downstream ambition is equally important. The project is expected to produce 105,000 t/yr of precursors and 30,000 t/yr of cathode materials. It also aims to build 20 GWh per year of nickel-based battery capacity. As a result, the Indonesia battery ecosystem project goes well beyond raw material processing.

Battery recycling also appears in the plan. The proposed recycling capacity is capped at 10,000 t/yr. That addition supports a more circular industrial model. Meanwhile, Antam will supply the nickel ore required for the project.

Antam Battery Project Reinforces Indonesia’s Downstream Strategy

The Antam battery project fits directly into Indonesia’s long-term downstream policy. Jakarta wants to build a local battery industry from mining to refining to final battery production. This new agreement supports that goal with another large integrated platform. Therefore, the project has national strategic value, not just commercial relevance.

This also shows Indonesia’s flexibility in partner management. LGES may have exited, but the broader industrial objective did not disappear. Instead, the project has been restructured around a new consortium. As a result, Indonesia continues pushing its battery ambitions despite partner turnover.

Antam’s role is becoming even more central. The company is involved in this project and also has a separate EV battery joint venture with CATL. That CATL-linked venture is expected to start operations by 2026. Consequently, Antam is emerging as one of the key anchors in Indonesia’s nickel battery chain.

The Metalnomist Commentary

This partnership matters because it shows Indonesia’s battery strategy is bigger than any one foreign partner. The country is still determined to convert nickel strength into downstream battery power. If execution improves, Indonesia could become one of the most integrated battery manufacturing hubs outside China.
