According to the industry sources, the Korean secondary battery materials maker will establish a new anode materials production facility near Sihwa multi-techno valley (MTV) in Korea. Once established, it will be capable of producing 150 tons of anode materials.

Meanwhile, Daejoo Electronic Materials will also expand the anode material production capacity of it headquarter facility in Sihwa, an one hour drive south of capital Seoul from 5 tons up to 20 tons per month.

What is characteristic of Daejoo Electronic Materials’ anode material is that silicon oxide is mixed with graphite to make the anode material. As silicon has 4times more energy capacity (or density) than graphite, it greatly increases the energy density of EV batteries. Thus, it will help increase a driving distance of EVs on a single charge.

Yet technological impediments still remain. Silicon bulges during battery charge and discharge processes, which significantly decreases the life-span of EV battery. The Korean anode materials maker is working on tackling the problem.

Daejoo Electronics plans to expand its business and sales to China and overseas market within the year.

It is the first to commercialize and mass-produce silicon-oxide-based anode materials in the industry.

Founded in 1981, Daejoo Electronic Materials is a manufacturer focused on developing electronic materials from epoxy insulation materials to conductive paste to phosphor to polymer materials. It recently jumped into battery business developing anode materials and graphite oxide.
