cartoon of crazed cat surrounded by fish and fish bones indicating positive and negative charges

An illustration, provided by the lab of Penn State researcher Huanyu "Larry" Cheng, of the manganese oxide @ cobalt manganese oxide capacitor. The bottom purple layer is N-doped graphene with upper purple layer manganese oxide @ cobalt manganese oxide separated by a filter paper separator. An induced electric field allows charging and discharging (blue lightning) of the capacitor, creating electrons (fish bones) and OH ions (fish). Shocking Tom (cat) represents shockingly fast electron and ion transport.
