EG Corporation announced on November 8 that the company is focusing on development of non-carbon anode material for lithium-ion batteries.
According to the company, such material will be able to solve the volume expansion issue, which is an issue for existing silicon-based anode materials, and improve safety issue and discharge capacity.
Since 2014, it has been working on a national project regarding “development of 1,500 mAh/g non-carbon anode material for 10Ah lithium-ion battery” with the Industry & Academic Cooperation in Chungnam National University, Chungbuk National University Industry – Academic Cooperation Foundation, and TopBattery.
It registered a patent for “silicon-carbon composite anode material and lithium rechargeable battery manufactured in respect to silicon-carbon composite anode material manufacturing method”.
“Level of interest towards rechargeable batteries is picking up.” said an EG official. “Companies including us are putting efforts into development of key materials of rechargeable battery such as cathode material and anode material.”
