Episode 115 of the Professor Alex Volinsky podcast. Potassium is abundant and its redox potential runs close to lithium's — but the K+ ion is substantially bigger, so each cycle strains the host more. Metal coordination materials (MOFs, Prussian blue analogues) offer open frameworks of cages and tunnels. No capacities or voltages are invented. Based on the paper: Recent Advances and Perspective on Metal Coordination Materials-based Electrode Materials for Potassium-ion Batteries: A Review; Fei Wang, Yong Liu, Hui-Jie Wei, Teng-Fei Li, Xun-Hui Xiong, Shi-Zhong Wei, Feng-Zhang Ren, Alex A. Volinsky; Rare Metals, 2021, Vol. 40(2), pp. 448-470. Hosts Elena and Marcus. AI-generated voices.
