Samsung has made significant progress in electric vehicle battery technology, unveiling its operational solid-state battery pilot production line at SNE Battery Day 2024 in Seoul. This development marks a potential milestone for the EV industry.
The company has already shipped sample cells to customers and received positive feedback. Samsung aims to begin mass production of these batteries by 2027, targeting an impressive energy density of 900 Wh/L – 40% higher than its current prismatic cells.
Key features of Samsung’s new solid-state batteries include:
- Extended range: Up to 600 miles (ca. 950 km) on a single charge
- Rapid charging: Just 9 minutes to reach full capacity
- Longevity: Estimated 20-year lifespan
- Improved energy density: 500 Wh/kg, nearly double current EV Li-ion batteries
These advances address key concerns in EV adoption, namely range anxiety and charging times. The solid-state design also promises improved safety and reduced size and weight compared to traditional lithium-ion batteries.
Samsung has already provided initial samples to EV manufacturers for testing and received positive feedback. However, due to high production costs, the technology will initially target the premium EV market. The company aims to mass produce these advanced batteries by 2026, while developing more affordable alternatives such as lithium iron phosphate (LFP) and cobalt-free options.
As the EV market expands, Samsung faces competition from Chinese manufacturers in this rapidly evolving sector. The focus on extending battery life to 20 years aligns with the industry trend toward “million-mile” batteries, potentially reducing long-term costs for consumers and environmental impact.
