Positioning Organic Electrode Materials in the Battery Landscape
A battery chemistry shall provide an E mater of ∼1,000 Wh kg −1 to achieve a cell-level specific energy (E cell) of 500 Wh kg −1 because a battery cell, with all the inert components such as electrolyte, current collectors, and packing materials added on top of the weight of active materials, only achieves 35%–50% of E mater. 2, 28 Figure …
Cathode
Diagram of a copper cathode in a galvanic cell (e.g., a battery). Positively charged cations move towards the cathode allowing a positive current i to flow out of the cathode. A cathode is the electrode from which a conventional current leaves a polarized electrical device such as a lead-acid battery..
