Indonesia's first export of electric vehicle batteries marks a shift for the Southeast Asian country, from exporting resources to exporting battery products. According to reports, on October 8, 2026, Indonesian President Prabowo Subianto witnessed Indonesia's first EV battery export at the Weda Bay Industrial Park in North Maluku, and launched 11 downstream industrial projects with total investment of US$10.2 billion — 4 projects entering commercial operation at US$3.4 billion and 7 new projects at US$6.8 billion, expected to create more than 10,000 jobs, covering nickel-based battery materials, power battery production, separators, electrolytes and battery recycling. For buyers in Indonesia and nearby markets, this is not an isolated news item but a sign that a regional battery supply chain is taking shape.

1. What do this export and investment actually mean?

Two levels should be kept apart. First, the export itself shows Indonesia already has EV battery products ready to deliver. Second, the investment structure — US$10.2 billion spread across materials, batteries, separators, electrolytes and recycling — shows the plan targets the whole chain, not a single plant. Nickel is Indonesia's traditional advantage, and turning nickel into battery materials and then into batteries and systems is a classic downstream extension. For buyers, a more complete chain can improve local supporting supply, delivery times and after-sales response, but product performance and certification still need to be checked item by item, not judged by the headline investment figure alone.

2. Why should overseas buyers watch Indonesia's battery chain?

Indonesia is one of the four overseas markets in focus this quarter, for three reasons: first, Southeast Asia's EV and energy storage markets are themselves growing, and local battery capacity can shorten regional supply chains; second, industrial parks such as Weda Bay concentrate materials and battery projects together, which helps a supplier cluster form; third, battery recycling is included in the same batch of projects, showing planners are already thinking about the full battery life cycle. For Indonesian PACK, module and system integrators, this means more local cell and material options may become available, and local supply stability can become one more factor in supplier evaluation.

3. What does a battery chain landing have to do with tab welding?

Facts and inference should be separated here. The fact is: battery chain expansion means output of cells, modules and battery packs grows together. The inference is: as output grows, metal welding steps such as cell tab welding and module busbar joining grow in number too, and demands on welding consistency and yield rise with them. An ultrasonic power battery welding machine is a common choice for such steps: the process produces no sparks, needs no solder, and suits thin copper, aluminium and other non-ferrous metals. It should be stressed that public reports do not disclose the process details of the Weda Bay projects, this article covers no order or tender information, and the welding angle is an inference based on common industry practice.

4. What is the advice for Indonesian and nearby buyers?

Three steps are suggested: first, check products and certification, and confirm whether cells and systems meet the standards and use cases of the target market; second, validate the welding process with real samples — weld with the actual tab material and stack structure and check pull force, weld appearance and consistency; third, check delivery and after-sales coverage, including commissioning, spare parts and operator training in Indonesia. Chain projects take time from launch to full output, and progress should be confirmed against later company and park announcements.
