State-owned coal miner Bukit Asam has launched a pilot project to convert coal into artificial graphite and anode sheets for lithium-ion (Li-ion) battery production. This initiative, in collaboration with the National Research and Innovation Agency (BRIN), is claimed to be the first of its kind globally.
Artificial graphite is a key material in anode production, while anode sheets serve as the positive electrode for oxidation reactions, making them essential components of Li-ion batteries.
Dilo Seno Widagdo, Director of Portfolio & Business Development at Bukit Asam's parent company MIND ID, said that all companies under the MIND ID Group are committed to maximizing the value of Indonesia's mineral and coal resources.
The pilot project is expected to advance toward commercial stages, and Dilo emphasized that its sustainability requires comprehensive support and thorough economic analysis.
“MIND ID is focused on supporting the electric vehicle battery ecosystem. Therefore, this potential must be fully backed by the entire MIND ID Group. This project is a strategic step that not only diversifies PTBA's business but also strengthens our position in the future supply chain of electric vehicle batteries,” Dilo said in an official statement on Tuesday.
PTBA President Director Arsal Ismail added that converting coal into artificial graphite and anode sheets reflects the company's commitment to supporting government policies aimed at enhancing coal downstream processing and ensuring national energy resilience.
"Bukit Asam aims to provide continuous energy for the nation. One of our efforts is to develop the coal industry using clean technology in Indonesia. The implementation of anode sheets made from coal is a world first, representing a significant breakthrough in coal downstream processing. This conversion will also support the advancement of the domestic electric vehicle industry," Arsal said.
Demand for artificial graphite and anode sheets is expected to rise, driven by growth in the electric vehicle sector. These materials are critical not only for electric vehicles but also for industries such as energy storage, electronics, and medical equipment.
Mulyadi Sinung Harjono, Director of Research Utilization & Innovation at BRIN said that the pilot project will strengthen Indonesia's position in the strategic raw materials industry.
"We hope that the collaboration with PTBA continues to produce beneficial research and that the pilot project proceeds as planned," he said.
