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].

Cathode healing methods for recycling of lithium-ion batteries
There are significant technology gaps in the recovery of lithium-ion battery materials that threaten the sustainability of these industries. Cathode healing is introduced here as a new approach to produce low cost (i.e. < $10/kg), recycled, battery grade electrode material. The soft-chemical treatment non-destructively recycles cathodes.
Dry Electrode Process might prove to be a Battery Cost Saver
The new coating process essentially uses similar raw materials as in the slurry process. According to the company, the dry coating technology works without solvents but instead uses a special binder. The materials form a dry mixture that is fed into a calender gap — a gap between two rollers rotating in opposite directions.
