The global automotive industry is undergoing a major shift toward electrification. Indonesia, possessing the world’s largest nickel reserves, plays a key role in the global supply chain [1]. However, long-term success does not depend on battery production alone. We must ensure that the batteries produced today do not become an environmental burden in the future.

The design for recycling (DfR) approach has become the gold standard for battery researchers and manufacturers. This concept requires that batteries be designed from the outset with ease of disassembly and material recovery in mind. By integrating these principles, we can create a sustainable circular economy [2].

The importance of design-for-recycling principles

Why is design from the start so crucial? Many current batteries use very strong permanent adhesives. This complicates mechanical separation processes when the battery reaches the end of its service life [3]. If manufacturers utilize modular designs, the disassembly process becomes significantly more efficient.

In addition to modularity, cell standardization also plays an important role. Researchers must focus on reducing the use of toxic binding agents. By simplifying chemical compositions, recycling facilities can process materials more quickly. This step also supports investing in electric vehicle battery recycling infrastructure: opportunities and challenges, which is currently being promoted in various regions.

The role of digitalization in battery management

Digital technology is a primary enabler in recycling strategies. The use of a digital battery passport allows for accurate tracking of a cell’s chemical history. This information is highly beneficial for recycling entities in determining the appropriate processing methods [4]. Without accurate data, the separation of cathode and anode materials becomes very difficult to perform.

The application of digital labels or QR codes on every battery pack ensures transparency. This also assists in effective collection systems for used electric vehicle batteries. With integrated data, manufacturers can predict when a battery will enter the recycling stage. This is a step forward for the ecosystem as the government encourages the development of an electric vehicle battery ecosystem in Indonesia.

Hydrometallurgy as a future solution

Once a battery is disassembled, the material extraction process becomes a critical stage. Hydrometallurgical methods are now preferred over pyrometallurgy. This wet chemical process offers a very high rate of material recovery [5]. Nickel, cobalt, and lithium can be recovered at rates of over 95 percent.

Beyond efficiency, this method consumes significantly less energy. Carbon emissions generated during the refining process are also drastically reduced. By leveraging the Ministry of Industry’s push to develop an electric vehicle battery recycling ecosystem, Indonesia can lead in the production of eco-friendly batteries.

Challenges in industrial implementation

Although the DfR concept is very promising, challenges in the field remain. The diversity of battery chemistries, ranging from NMC to LFP, requires high flexibility. Manufacturers must work with researchers to create uniform standards. Furthermore, the initial investment cost for hydrometallurgical facilities is still considered quite high.

Logistics systems or reverse logistics also need to be improved. Collecting used batteries from consumers to processing centers requires an integrated supply chain. Without strong policy support, these efforts will struggle to reach the expected economies of scale. The government must continue to strengthen hazardous waste (B3) management regulations to ensure environmental safety.

Building a sustainable future

A circular economy is no longer just an option, but a necessity. By designing batteries that are easy to recycle, we reduce dependence on mining new raw materials. This preserves Indonesia’s nickel reserves for long-term needs. Additionally, this step significantly reduces the carbon footprint of the automotive industry.

Manufacturers must begin to consider recycling aspects in every design decision. Collaboration between upstream and downstream sectors, as demonstrated by IBC’s focus on building an EV battery ecosystem from upstream to downstream, is the right model. With this synergy, Indonesia will become a major player in the global sustainable electric vehicle market.
