Researchers from the University of Southern California developed better performing and cheaper Li-Ion batteries. The researchers developed new cathode and anode materials.
The anode in the new batteries is made from Silicon, and they say that this anode is three times more powerful and longer lasting compared to a typical graphite anodes. The cathode they used is made from sulfur powder coated with graphene oxide.
Sulfur is a promising cathode material, but it has poor conductivity and poor cyclability. But coating the sulfur with GO proved to solve this issues, and the newly developed cathodes offer 5 times the capacity of commercial cathodes.
