About Photovoltaic Energy StorageThese effects have resulted in a decrease in the use of active materials in the positive electrode. The transition from α-PbO 2 (>10 μm) to β-PbO 2 (<1.5 μm) could change the structural property of the PAM. The small-size β-PbO 2 particles could induce softening and shedding of the active material in the positive electrode [49, 67, 68].
About Photovoltaic Energy StorageThe porosity of the positive electrode is an important parameter for battery cell performance, as it influences the percolation (electronic and ionic transport within the electrode) and the mechanical properties of the electrode such as the E-modulus and brittleness [4,5,6,7,8]. Furthermore, the porosity is key for the cell design, as it co ...
