Direct Electrochemical Leaching Method for High-Purity Lithium Recovery from Spent Lithium Batteries

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(11), P. 4591 - 4597

Published: March 7, 2023

Recovering lithium from batteries (LIBs) is a promising approach for sustainable ternary battery (T-LIB) development. Current recovery methods spent T-LIBs mainly concentrated on chemical leaching methods. However, relying the additional acid seriously threatens global environment and nonselective also leads to low Li purity. Here, we first reported direct electro-oxidation method (Li0.8Ni0.6Co0.2Mn0.2O2); 95.02% of in was leached under 2.5 V 3 h. Meanwhile, nearly 100% purity achieved, attributed no other metal agents. We clarified relationship between metals during T-LIBs. Under optimized voltage, Ni O maintain electroneutrality structure assisting leaching, while Co Mn their valence states. A achieves high meanwhile overcomes secondary pollution problem.

Self‐Reconstruction of Highly Degraded LiNi_0.8Co_0.1Mn_0.1O₂ toward Stable Single‐Crystalline Cathode

Advanced Materials, Journal Year: 2023, Volume and Issue: 36(5)

Published: Oct. 20, 2023

Abstract The ever‐growing demand for resources sustainability has promoted the recycle of spent lithium‐ion batteries to a strategic position. Direct outperforms either hydrometallurgical or pyrometallurgical approaches due high added value and facile treatment processes. However, traditional direct recycling technologies are only applicable Ni‐poor/middle cathodes. Herein, Ni‐rich LiNi 0.8 Co 0.1 Mn O 2 (S‐NCM) performance‐enhanced single‐crystalline cathode materials is directly recycled using simple but effective LiOH‐NaCl molten salt. evolution process Li‐supplement grain‐recrystallization during regeneration systematically investigated, successful recovery highly degraded microstructure comprehensively proven, including significant elimination Ni 2+ vacancies. Beneficial from favorable reconstructed particles, regenerated NCM (R‐NCM) represents remarkably enhanced structural stability, electrochemical activity, cracks suppression charge/discharge, thus achieving excellent performances in long‐term cycling high‐rate tests. As result, R‐NCM maintains 86.5% reversible capacity at 1 C after 200 cycles. Instructively, present salt can be successfully applied NCMs with various Li compositions (e.g., 0.5 0.2 0.3 ).

Published: July 24, 2024

Abstract Effective recycling of end-of-life Li-ion batteries (LIBs) is essential due to continuous accumulation battery waste and gradual depletion metal resources. The present closed-loop solutions include destructive conversion compounds, by destroying the entire three-dimensional morphology cathode through thermal treatment or harsh wet extraction methods, direct regeneration lithium replenishment. Here, we report a solvent- water-free flash Joule heating (FJH) method combined with magnetic separation restore fresh cathodes from cathodes, followed solid-state relithiation. process called recycling. This FJH exhibits merits milliseconds duration high recovery yields ~98%. After FJH, reveal intact core structures hierarchical features, implying feasibility their reconstituting into new cathodes. Relithiated are further used in LIBs, show good electrochemical performance, comparable commercial counterparts. Life-cycle-analysis highlights that has higher environmental economic benefits over traditional processes.
