Figure 1: Schematic illustration of a coin cell design loaded with a TEM grid.
From: Phase evolution for conversion reaction electrodes in lithium-ion batteries
In the coin cell, a holey carbon supported TEM grid, which was loaded with a small amount of the anode material, was pressed against the bulk anode to ensure the materials on the grid are submerged in the same electrolyte environment as the bulk anode. From top to bottom: anode cap, spring, spacer, lithium anode, gasket, separator, TEM grid loaded with NiO nanosheets, working electrode and cathode cap. A NiO-based working electrode is considered as a ‘cathode’ in this half-cell configuration but as an ‘anode’ in the full-cell configuration. Therefore, a NiO-based working electrode is identified as an ‘anode’ in this paper.
