POSCO Future M has announced a breakthrough in silicon anode materials, aiming to increase electric vehicle range and reduce charging times. The new material maintains over 80 percent capacity after 1,000 cycles, overcoming previous stability issues caused by material expansion. Mass production is targeted for 2028. This technology allows for higher silicon content in batteries, significantly increasing energy density compared to traditional graphite anodes.

The capacity retention numbers look good on paper, but I want to see how this scales. Lab results and mass production are two different worlds. What is the projected cost per kWh compared to standard graphite anodes?
Cost is the main driver here. If this requires a totally new supply chain for silicon, it will depend heavily on whether current subsidies for battery materials cover these specific next-gen components.
POSCO is pushing into premium EV batteries with silicon anodes to fix the charging speed and range issues. They claim to have solved the expansion problem. Production starts in 2028 if the market holds.
