POSCO Future M develops‘Dream Material’

Targeting Mass-Production of Silicon Anode Materials by 2028

Applying new silicon nano-sizing technology
Expected to be a game changer in K-battery

 POSCO Future M has secured mass-production technology for silicon anode material, considered one of the core next-generation battery materials. The company plans to target future battery markets, including premium electric vehicles, humanoid robots and urban air mobility (UAM), with the goal of commercialization by 2028. Silicon anode materials are often referred to within the battery industry as a ‘dream battery material’ because they are considered next-generation technology that can significantly improve the battery performance of electric vehicles.

In batteries, the anode material stores electricity. Until now, graphite has been widely sued due to its stability and price competitiveness, but it faces limitations when it comes to storage capacity. Silicone, on the other hand, has a thinner structure and enables faster electron movement, allowing it to store significantly more lithium ions than graphite. This means that a battery of the same size can store more electricity.
For this reason, it is attracting attention as core technology — not only for premium electric vehicles but also for industries where energy efficiency and lightweight design are critical, including humanoid robots, UAM, and drones.
A POSCO Future M official explained, “Competition in battery performance is expanding beyond cathode materials into anode materials. Commercializing silicon anodes is an area drawing intense interest from global battery manufacturers because it can improve both driving range and charging speed.”
While other battery makers have also been developing silicon and anode technologies, POSCO Future M stands out for increasing the proportion of silicon anodes to over 20% of its total anode materials.
