The boom in electric vehicles is ushering in a new era for the automotive industry. However, this comes with immense pressure regarding the management of Lithium-ion battery waste once they reach the end of their life cycle. Recycling precious metals from EV batteries is not only an environmental challenge but also a strategic economic opportunity for investors in Vietnam.
Strategic metals such as Lithium, Nickel, Cobalt, and Manganese play a key role in battery architecture. Efficiently recovering these components helps reduce reliance on natural mineral extraction and protects the global supply chain [2]. To better understand this roadmap, you can refer to the article on circular economy for electric vehicle batteries: recycling and reuse strategies.
Modern EV battery recycling technology
Currently, the world is applying various advanced methods to extract metals from batteries. Each technology offers unique advantages and limitations for businesses.
Hydrometallurgy – a high-purity solution
Hydrometallurgy uses chemical solutions to dissolve cathode materials. This method allows for the recovery of over 95% of precious metals like Lithium and Cobalt in pure form [1]. This is the technology chosen by many large corporations to ensure standards for new battery production.
Pyrometallurgy – large-scale processing
Pyrometallurgy uses extremely high temperatures to melt down batteries. Although it can process large volumes, this method often results in the loss of Lithium into slag. Additionally, the energy consumption of pyrometallurgy is very high, putting pressure on carbon emission reduction commitments.
Direct recycling
Direct recycling technology focuses on restoring the crystal structure of the cathode without completely destroying the material [3]. This is a potential pathway to maximize energy savings and reduce chemical costs in the future.
Current status and legal framework in Vietnam
Vietnam is facing a wave of end-of-life EV batteries expected to surge from 2030. The government has issued specific regulations to control this issue. Under Decree 08/2022/NĐ-CP, Extended Producer Responsibility (EPR) has become a key lever. Businesses are required to build professional battery collection and recycling systems.
Many domestic units have begun proactively cooperating with international partners. These alliances not only help with technology transfer but also enhance the capacity to manage hazardous waste.

Major challenges for investors
Despite the immense potential, recycling companies in Vietnam still face many technical and infrastructural barriers.
Lack of synchronized infrastructure
Currently, Vietnam primarily stops at the mechanical dismantling stage. Factories using advanced hydrometallurgical technology are still scarce. This leads many units to export "black mass" instead of refining it domestically.
Logistics and safety issues
Lithium-ion batteries are hazardous waste with a high risk of fire and explosion during transport. The investment cost for standardized storage systems and specialized transport teams is very high. This is a factor that investors need to consider carefully [4].
Specialized human resources
Operating a recycling line requires engineers with deep knowledge of material chemistry. Currently, this human resource pool in Vietnam is limited, requiring businesses to invest heavily in internal training. The scarcity of talent is also one of the challenges regarding strategic mineral supply globally.
The future of the battery recycling industry in Vietnam
To succeed, investors need to view battery recycling not just as an environmental obligation but as a sustainable business model. Applying direct or hydrometallurgical recycling technology will help optimize profits from precious metal recovery [5]. Close coordination between manufacturers, recyclers, and regulatory agencies will create a complete circular ecosystem.
In the long term, as the volume of end-of-life EV batteries increases, economies of scale will improve. This is the golden time for pioneer businesses to lay the foundation for recycling technology in Vietnam.
