China’s Reliance Batteries is preparing to advance a planned €100.5 million ($118 million) battery factory in Serbia, with agreements on the investment scheduled for 31 August 2026 as the country develops a growing concentration of technology-oriented manufacturing around Inđija. Serbian President Aleksandar Vučić said on 29 August that contracts for the project would be signed on 31 August, moving the investment toward the construction phase after it was announced earlier in August.
- Battery and robotics projects expand Inđija’s industrial profile
- Local production will determine economic impact
- Labour constraints are pushing investment toward automation
- Battery demand is broadening beyond electric vehicles
- EU requirements could influence production decisions
- Chinese capital is moving into higher-technology industries
- August agreements will precede construction
The planned facility is expected to employ approximately 250 people and produce batteries for drones, unmanned vehicles, robots and other applications. Construction is targeted to begin in late October 2026. The investment comes as Serbia seeks to attract more capital into robotics, batteries and AI-enabled hardware while reducing its reliance on labour-intensive manufacturing.
Battery and robotics projects expand Inđija’s industrial profile
The Reliance project is developing alongside a wider technology investment pipeline.
China’s Minth Group opened an initial €20 million humanoid-robot manufacturing facility in Šabac on 29 August, while Serbian authorities have also presented plans for a larger robotics industrial park around Inđija. Together, the projects could create links between battery production, robotics, drones, automotive manufacturing and software. The extent of those potential connections, however, will depend on how much production and technology are ultimately located in Serbia.
For Reliance, the level of local integration will be particularly important. Battery manufacturing can cover activities ranging from assembling imported cells into modules and packs to higher-value operations such as cell production, battery-management systems, electronics, testing and engineering. Serbian officials have not yet provided sufficient technical information to determine where the planned Inđija facility will sit within that value chain.
Local production will determine economic impact
If the plant primarily assembles imported Chinese cells, it would still generate employment and exports but would create less domestic value added. Production of cells, electronics and control systems would represent a deeper technological investment and could create opportunities for Serbian engineering companies and suppliers. Potential local inputs could include metal structures, wiring, cooling systems, electronics, software, testing and battery-management technology. More advanced cell chemistry and manufacturing equipment could initially remain dependent on foreign technology.
The degree of localisation will also influence how much the investment improves the technological sophistication of Serbia’s exports rather than simply increasing overall manufacturing shipments. That issue is becoming more relevant as Serbia moves closer to the European Union and faces increasingly demanding requirements concerning product origin, industrial subsidies, environmental standards and supply-chain traceability.
Labour constraints are pushing investment toward automation
Inđija has developed into a major industrial location because of its position between Belgrade and Novi Sad, proximity to the A1 motorway and access to Belgrade airport. The municipality already hosts manufacturing and logistics investments. The addition of battery and robotics facilities would further shift its industrial profile toward more technology-intensive activities.
Serbia has attracted billions of euros in foreign investment over the past decade, particularly in automotive components, metals, machinery, tyres and electronics. At the same time, labour availability has tightened and wages have increased.
The country’s unemployment rate fell to 7.2% in the second quarter of 2026, while employment was also lower than a year earlier, indicating a shrinking available workforce rather than simply stronger job creation. For manufacturers, the resulting pressure is to increase production through automation, machinery and higher productivity. Battery and robotics facilities generally require greater capital and technical expertise per employee than traditional assembly operations.
Battery demand is broadening beyond electric vehicles
The Reliance project targets battery applications outside the passenger-car market. Electric vehicles remain a major source of global battery investment, but demand is also expanding in stationary energy storage, industrial equipment, drones, robotics and autonomous systems. Such applications can require different battery characteristics from passenger vehicles, including low weight, high power density, rapid charging, thermal management and long cycle life.
That creates opportunities for specialised battery manufacturers alongside large-scale electric-vehicle cell producers.
Serbia is simultaneously developing industrial segments that could eventually create domestic demand for these technologies, including robotics, unmanned systems and battery energy storage. Minth’s Šabac operation is expected to manufacture humanoid and quadruped robots primarily for export, creating a potential local market for specialised battery technologies. There is currently no confirmed indication that Reliance will supply Minth or other Serbian robotics manufacturers.
EU requirements could influence production decisions
Serbia is outside the European Union but is closely integrated with European manufacturing supply chains. This has made the country attractive to Chinese manufacturers seeking production locations near EU customers while maintaining lower operating costs than many Western European markets. Battery manufacturing is increasingly subject to European requirements covering carbon footprints, recycling and supply-chain due diligence, among other areas.
A Serbian factory targeting European customers will therefore need to comply with increasingly stringent technical and environmental requirements. Local engineering capabilities and traceability systems could become more important under those conditions. Renewable electricity procurement could also become relevant because the carbon intensity of battery production is increasingly considered by European buyers. Serbia’s power system remains relatively carbon intensive because of its reliance on lignite-fired generation, creating an additional consideration for manufacturers that may need renewable electricity contracts or on-site generation to address production-related emissions.
Chinese capital is moving into higher-technology industries
Reliance’s investment forms part of a broader change in the composition of Chinese investment in Serbia. Earlier Chinese projects were heavily concentrated in infrastructure and heavy industry. HBIS acquired the Smederevo steel mill, while Zijin Mining became a major investor in Serbia’s copper and gold sector. Chinese companies have also participated in major motorway and railway projects and established a substantial automotive supplier base.
The newer pipeline includes batteries, renewable energy, robotics and advanced manufacturing, offering Serbia an opportunity to increase the technological content of incoming foreign investment. At the same time, the expansion of Chinese capital and technology comes as the EU, Serbia’s largest trading partner, increases scrutiny of Chinese industrial investment.
August agreements will precede construction
The scheduled 31 August agreements represent the next milestone for Reliance’s Inđija project. Following the signing, the project will move toward issues including land, permits, financing, construction and production equipment. Maintaining the planned late-October 2026 construction start would leave a relatively short period between the agreements and the beginning of works.
Further technical information will be needed to establish the plant’s planned annual capacity, battery chemistry, cell sourcing, export destinations and level of Serbian content. Those parameters will determine the extent to which the €100.5 million project functions as an export-oriented assembly operation or develops into a more integrated addition to Serbia’s battery and technology manufacturing base. For Serbia, the investment forms part of a broader effort to attract factories that combine manufacturing with engineering, technology and domestic suppliers, as labour constraints increasingly affect traditional production models.
