These 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].
