Electrodes are critical parts of every battery architecture – charge too fast, and you can decrease the charge-discharge cycle life or damage the battery so it won’t charge anymore. Scientists built a new design and chemistry for electrodes. Their design involves advanced, nanostructured electrodes containing molybdenum disulfide and carbon nanofibers. These composite materials have internal atomic-scale pathways. These paths are for both fast ion and electron transport, allowing for fast charging.
