The battery reportedly uses sulfur as a key material in the cathode and a silicon-based anode. The company said it now aims to improve the durability of the anode , so it can commercialize the next-generation lithium-ion battery by 2020.

To formulate the cathode material, GS Yuasa fills sulfur into small holes on carbon rods, the company said.
