BACK Beyond Lithium: Revealing the Upstream Mining Sources for Electric Vehicle Battery Production
Electric Vehicles (EVs) are gaining widespread popularity, especially in Thailand, due to their eco-friendliness and cost-saving benefits compared to gasoline-powered cars. However, behind this convenience lies a complex upstream industry, heavily reliant on extracting essential minerals required for EV battery production within industrial estates.
Key Minerals in EV Battery Production
- Lithium: Used as a cathode in EV batteries and is known for its excellent electric charge storage capabilities.
- Nickel: Utilized in the cathode alongside cobalt and manganese, contributing to the battery’s capacity and efficiency.
- Cobalt: Works with nickel in the positive electrode, enhancing battery stability and extending lifespan.
- Manganese: Combined with nickel and cobalt in the positive electrode, it helps lower costs and improve battery safety.
- Graphite: Serves as the anode in some types of EV batteries and is valued for its superior electrical conductivity.
In recent years, it has been discovered that Thailand holds reserves of potassium minerals, which are being actively researched and developed for use in the battery industry.
Potash Mining Discovery in Thailand
According to the Department of Primary Industries and Mines, the northeastern region of Thailand is rich in potash, from which sodium oxide can be extracted as a raw material for EV battery production. These reserves are estimated to hold up to 18 trillion tons, ensuring a supply that could last for 100 years. Additionally, Dr. Nonglak has noted that the production cost of sodium-ion batteries is half that of lithium batteries. Chinese companies like BYD have already begun testing sodium-ion batteries, but in Thailand, no industrial estate has yet invested in producing batteries from potash-derived sodium.
GPI Unveils Prototype Potash-Ion EV Battery
In addition to lithium-based batteries, sodium-ion batteries are now under development. In a promising development, a research team led by Associate Professor Dr. Nonglak Midthong from the Faculty of Science at Khon Kaen University has completed a prototype sodium-ion battery. The prototype utilizes sodium extracted from potash deposits in Thailand’s northeastern region, and the team is awaiting investors to begin large-scale production.
Investment promotion efforts by the Board of Investment (BOI) have already attracted major Chinese EV manufacturers to establish production facilities in Thailand’s industrial estates. As the availability of sodium from potash grows, mining and extraction processes are expected to develop locally, paving the way for investment in sodium-ion battery production. This will help transform Thailand into a comprehensive and fully integrated EV manufacturing hub.
Moreover, the 304 Industrial Park boasts a strategic geographic advantage, providing access to a large workforce from northeastern Thailand. This labor pool, combined with the region’s ample electrical infrastructure, offers a significant benefit to investors, allowing them to operate smoothly and efficiently in the battery manufacturing sector.
