POSCO Future M is developing silicon anode materials to replace traditional graphite in batteries. This technology aims to increase energy storage capacity and reduce charging times for premium electric vehicles, humanoid robots, and urban air mobility systems. The company uses nano-scale processing and carbon composite coatings to prevent the material expansion that typically degrades silicon batteries. Their current tests show the material maintains over 80 percent capacity after 1,000 cycles with a silicon content exceeding 20 percent.
