Recycled LiNi1/3Mn1/3Co1/3O2 demonstrates superior rate and cycle performance, outperforming commercial materials and providing a green and sustainable solution for spent lithium-ion batteries.
Recycling spent lithium-ion batteries plays a significant role in alleviating the shortage of rawmaterials and environmental problems. However, recycled materials are deemed inferior to commercial materials, preventing the industry fromadopting recycledmaterials in new batteries. Here, we demonstrate that the recycled LiNi1/3Mn1/3Co1/3O2 has a superior rate and cycle performance, verified by various industry-level tests. Specifically, 1 Ah cells with the recycled LiNi1/3Mn1/3Co1/3O2 have the best cycle life result reported for recycled materials and enable 4,200 cycles and 11,600 cycles at 80% and 70% capacity retention, which is 33% and 53% better than the state-of-the-art, commercial LiNi1/3Mn1/3Co1/3O2. Meanwhile, its rate performance is 88.6% better than commercial powders at 5C. From experimental and modeling results, the unique microstructure of recycled materials enables superior electrochemical performance. The recycled material outperforms commercially available equivalent, providing a green and sustainable solution for spent lithium-ion batteries.
