Doped carbon for a reliable lithium sulfur battery
Scientists in South Korea developed a porous carbon material that, when applied as a coating to the separator film in a lithium-sulfur battery, was shown to reduce an unwanted side effect and improve the battery’s performance and reliability. The coating is based on methylene blue, a type of salt commonly used in textile dying.
A 15.2%-efficient solar cell that you can fold in half
Scientists in South Korea developed a foldable thin-film device with some promising characteristics. Integrating a perovskite cell material and a carbon nanotube electrode, the group fabricated a device that achieved 15.2% efficiency and could withstand being folded more than 10,000 times at a bending radius of 0.5mm.
