Battery electrode materials need to do a lot of things well. They need to be conductors to get charges to and from the ions that shuttle between the electrodes. They also need to have an open ...

The new cathode material is a crystal composed of sulfur and iodine. The cathode material has a low melting point of 65 Celsius, enabling self-healing of damaged interfaces. A test battery constructed ...

Massachusetts Institute of Technology (MIT) researchers have developed a new organic cathode material with an energy density higher than most cobalt-based cathodes. It can charge–discharge in as ...
