The cell electrode pressure is required to keep the cell operating at it’s peak performance over it’s lifetime. However, is there an optimum pressure and why exactly does the cell need it? As the cell is charged lithium ions move into the graphite anode and the cell will increase in thickness.
Outperforming prior organic electrodes, pressurized organic electrodes excel under challenging/extreme condition including high mass loadings (50–150 mg cm −2), active material fraction (up to 95%), low N/P ratio (0.8–2), and lean electrolyte, delivering high areal/volumetric capacity in full cells.
As a result, organic electrodes treated with higher pressure demonstrate better capacity, rate, and cycling performance in batteries.
The improved capacity, rate, and cycling performance of pressurized electrodes result from pressure-induced structural and property changes in organics including crystal orientation, enhanced π-π interaction, favorable electrode porosity/tortuosity, accelerated chemical reactivity, and boosted electronic conductivity.
Pressure densification was evident at both the material and electrode level, as reflected in reduced occupied space at the same mass and higher density attained in POEs (Fig. 6f). Comparative evaluations against unpressurized electrodes demonstrated lower sheet and bulk resistance in all organics within POEs (Fig. 6g).
Therefore, it is essential to clarify the mechanism of the influence exerted by stack pressure on the electrode - SE interface in SSBs, and to ascertain the optimal mode and level of the stack pressure applied, in order to ensure the formation of a superior contact between the electrode and the SE, enhancing the overall performance of SSBs.
