POSCO Future M said Wednesday it has secured mass production technology for silicon anode materials, a next-generation battery component seen as critical to extending electric vehicle driving range and cutting charging times.
The company said the breakthrough positions it to move aggressively into the premium EV market, where automakers are increasingly demanding higher energy density and faster charging performance.
Silicon anode materials can store more than four times the energy of conventional graphite-based anodes, making them one of the industry’s most closely watched battery technologies.
POSCO Future M said its newly developed material maintained more than 80 percent of its original capacity after 1,000 charge-discharge cycles, even when silicon content exceeded 20 percent in testing.
