May 20 (Asia Today) -- South Korean battery materials company POSCO Future M said Wednesday it has secured technology for mass production of silicon anode materials, with plans to commercialize the product by 2028 as demand grows for high-performance electric vehicle batteries.
The company said its silicon anode material can store more than four times the energy of conventional graphite-based anodes commonly used in lithium-ion batteries.
Silicon anodes are considered a key next-generation battery material because they can significantly improve energy density and charging speed. The technology is expected to see broader adoption in premium electric vehicles, robotics, humanoid systems and urban air mobility platforms.
POSCO Future M said battery tests using silicon anodes blended at more than 20% maintained over 80% of initial battery capacity after 1,000 charge-discharge cycles. The company said that level exceeds the single-digit blend ratios commonly used in existing commercial batteries.
