KRICT researchers develop cathode technology for high-capacity batteries

A research team at the Korea Research Institute of Chemical Technology (KRICT) has developed a new cathode technology that could help batteries store more energy without increasing their size or weight, the institute said Monday. The team, led by senior researchers Moon San and Suk Jung-don, developed a new dry thick cathode technology that improves the movement of lithium ions inside electrodes. The research was featured as the cover article of the international academic journal Exploration in August, with post-master's researcher Eun Hye-ji as the first author. The technology uses graphitic carbon nitride as an additive in dry cathodes for the first time, helping the electrolyte penetrate deeper into the electrode and reducing the energy required for lithium ions to enter the cathode material. One way to produce high-energy-density batteries is to make electrodes thicker, as this allows more active material to be packed into the same area. However, as electrodes become thicker, lithium ions have more difficulty moving through them, preventing the battery from fully utilizing the energ
