Abstract As Sodium‐ion battery (SIB) technology progresses toward commercial viability, sustainable end‐of‐life (EOL) management is critical. Methods for recycling key components such as hard carbon (HC), a negative electrode material, remain underexplored. This study introduces direct and efficient approach HC from production scrap EOL cells using “ice‐stripping” followed by low‐temperature binder negation at 300 °C under nitrogen. The effects of temperature on structural integrity electrochemical performance are comprehensively characterized XRD, Wide‐Angle X‐ray Scattering (WAXS), XPS. Heating above 400 induces irreversible damage to HC's graphene layers modifies the surfaces, resulting in poor performance. However, reclaimed retains near‐pristine performance, with capacities 243 mAh g⁻¹ (scrap) 228 after 50 cycles. Full‐cell configurations demonstrates robust cycling stability, 86% 89% capacity retention 200 cycles derived cells, respectively. work highlights potential lower‐temperature, enable circular economy SIBs. findings set benchmark developing methods other SIB components.

Separation and Recovery of Cathode Materials from Spent Lithium Iron Phosphate Batteries for Sustainability: A Comprehensive Review

Industrial & Engineering Chemistry Research, Год журнала: 2024, Номер 63(32), С. 13945 - 13965

Опубликована: Авг. 1, 2024

In the past decade, traditional fuel vehicles have gradually been replaced by electric (EVs) to help reduce consumption of fossil fuels and emissions greenhouse gases, lithium iron phosphate (LFP) batteries stand as one promising power such EVs, because their cost-effectiveness high energy density. However, with increasing number EVs each year end-of-life LFP batteries, proper recycling spent (SLFP) has become an unavoidable challenge. As such, development a green, efficient, low-cost method recycle SLFP is crucial importance, which will benefit industries for manufacturing EVs. To this end, we provide review focus on understanding current summarizing research status technological challenges existing in batteries. Specifically, detailed elucidations regarding environmental risks common techniques deployed separating cathode materials, state-of-the-art methods used materials. Additionally, after comprehensive comparison methodologies perspectives optimizing deployments toward industry-scale processing are provided.

Effect of Gas Oversaturation Degree on Flotation Separation Performance of Electrode Materials from Spent Lithium-Ion Batteries

Minerals, Год журнала: 2025, Номер 15(6), С. 560 - 560

Опубликована: Май 24, 2025

The electrode materials from spent lithium-ion batteries consist of graphite and lithium cobalt oxides (LCO), which cannot be efficiently separated by the conventional flotation technique due to fine size distributions LCO. In this work, nanobubbles were introduced system materials. Nanobubbles produced with method temperature difference. Different degrees gas oversaturation in water/slurry achieved raising cold water (stored at 4 °C for least 72 h) target values 20 °C, 25 30 °C. It was found that height lateral distance increased degree water. addition, larger agglomerations observed form presence nanobubbles. D50 (chord length) 8 μm, 11 21 respectively, compared natural More adhered a captive bubble aid than case no nanobubbles, indicated wrapping angles (agglomerations) adhering bubble. Furthermore, maximum adhesion force between substrate increases 220, 270, 300 μN as 20, 25, respectively. frost on surface resulting through bridging effect are thought responsible improved performance present results indicate minerals can regulated regulating slurry.
