POSCO Future M's silicon anode material demo plant (prototype factory) in Yeongilman Industrial Complex, Buk-gu, Pohang-si, Gyeongsangbuk-do on the 7th. After entering the product warehouse, the researcher entered the password and opened a humidity sample storage box that looked like a large safe. Inside, a number of fine dark gray powders were displayed in several tens of mL glass bottles. This powder is the actual silicon anode material, which is expected to become the ‘dream material’ for the future battery market. This is the first time that the plant, which began operation in 2024, has been revealed to the media. Silicon anode material, a key material that acts as a storage device when lithium-ion batteries are charged, is made of silicon instead of graphite. Thanks to silicon's unique swelling characteristics, it can store more than four times more energy than graphite anode materials. The charging speed is also faster. ● “Prepared for mass production in 2028” In the battery industry, there are many predictions that the ‘era of silicon cathode materials’ will open when the related markets such as high-performance autonomous electric vehicles and humanoid robots, which require high-efficiency batteries, become in full swing.
