1Ah cells with recycled NMC111 achieve 4200 cycles and 11600 cycles at 80% and 70% capacity retention, a 33% and 53% improvement compared to state-of-the-art commercial NMC111.
Recycled materials have optimized microstructures for larger surface area, cumulative pore volume, and larger internal voids.
This yields a higher Li chemical diffusion coefficient, mitigating the strain during cycling and leading to less phase transformation. Producing high-performing recycled materials comparable to pristine cathode materials will be essential in driving a circular economy.
