Coronene: A High-Voltage Anion De-insertion Cathode for Potassium-Ion Battery

revised on 07.12.2020, 07:00 and posted on 08.12.2020, 05:17 by Minami Kato, Titus Masese, Kazuki Yoshii
Potassium-ion batteries have been envisioned to herald the age of low-cost and high-performance energy storage systems. However, the sparsity of viable components has dampened the progress of these energy devices. Thus, herein, we report coronene, a high-voltage cathode material that manifests a high-voltage of 4.1 V enkindled by anion (de)insertion. This work not only illuminates the broad class of polycyclic aromatic hydrocarbons as prospective cathode materials but also sets a new benchmark for the performance of future organic cathode materials.
