Researchers at the Korea Research Institute of Chemical Technology have created a novel cathode technology that could enable batteries to store more energy without increasing their size or weight, according to a statement released Monday. Led by senior scientists Moon San and Suk Jung-don, the team brought forth a new dry thick cathode technology that enhances the flow of lithium ions within electrode materials.
The research was showcased as the cover story in the August issue of the prestigious academic journal Exploration, with post-master's researcher Eun Hye-ji leading the effort. The groundbreaking technology introduces graphitic carbon nitride as an additive in dry cathodes for the very first time, facilitating the electrolyte to penetrate deeper into the electrode.
This innovation reduces the energy needed for lithium ions to enter the cathode material. One approach to creating high-capacity batteries is by making electrodes thicker, allowing for more active material to be packed into the same space. However, as electrodes become thicker, lithium ions face greater challenges moving through them, limiting the battery's ability to fully leverage its energy potential.
