Organic pH Buffer for Dendrite‐Free and Shuttle‐Free Zn‐I₂ Batteries

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(21)

Опубликована: Март 23, 2023

Aqueous Zn-Iodine (I2 ) batteries are attractive for large-scale energy storage. However, drawbacks include, Zn dendrites, hydrogen evolution reaction (HER), corrosion and, cathode "shuttle" of polyiodines. Here we report a class N-containing heterocyclic compounds as organic pH buffers to obviate these. We evidence that addition pyridine /imidazole regulates electrolyte pH, and inhibits HER anode corrosion. In addition, imidazole preferentially absorb on metal, regulating non-dendritic plating /stripping, achieving high Coulombic efficiency 99.6 % long-term cycling stability 3200 h at 2 mA cm-2 , mAh . It is also confirmed polyiodines shuttling boosts conversion kinetics I- /I2 As result, the Zn-I2 full battery exhibits long cycle >25 000 cycles specific capacity 105.5 g-1 10 A conclude buffer engineering practical dendrite-free shuttle-free batteries.

Boosting Reversibility and Stability of Zn Anodes via Manipulation of Electrolyte Structure and Interface with Addition of Trace Organic Molecules

Advanced Energy Materials, Год журнала: 2022, Номер 12(38)

Опубликована: Авг. 17, 2022

Abstract The practical application of aqueous zinc‐ion batteries (AZIBs) is significantly limited by poor reversibility and stability the Zn anode. Here, first time addition trace organic gamma butyrolactone (GBL) reported to a typical ZnSO 4 electrolyte controllably manipulate structure interface. Judiciously combined experimental characterization theoretical computation confirm that GBL additive weakens bonding strength between 2+ ion solvated H 2 O rearranges “Zn −H O−SO 2– GBL” network reduce water activity suppress corrosion side products. molecules preferentially absorb on surface anode give uniform compact deposition. As result, boosted run over 3105 cycles (6210 h) with average Coulombic efficiency 99.93% under 1 mA cm –2 mAh , exhibit stable cycling for 1170 h harsh testing conditions 10 . Additionally, Zn–MnO full cells using –GBL high capacity 287 g –1 at 0.5 A good retention 87% following 400 cycles. These findings will be immediate benefit design low cost AZIBs clean energy storage.

A Universal Molten Salt Method for Direct Upcycling of Spent Ni‐rich Cathode towards Single‐crystalline Li‐rich Cathode

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(25)

Опубликована: Апрель 21, 2023

Abstract With ever‐increasing pursuit for high‐value output in recycling spent lithium‐ion batteries (LIBs), traditional methods of cathodes tend to be obsolete because the complicated procedures. Herein, we first upcycle polycrystal LiNi 0.88 Co 0.095 Al 0.025 O 2 (S‐NCA) high value‐added single‐crystalline and Li‐rich cathode materials through a simple but feasible LiOH‐Na SO 4 eutectic molten salt strategy. The situ X‐ray diffraction technique series paratactic experiments record evolution process upcycling prove that excessive Li occupies transition metal (TM) layers. Beneficial from nature, regenerated NCA (R‐NCA) exhibits remarkably enhanced electrochemical performances terms long‐term cyclability, high‐rate performance low polarization. This approach can also successfully extended other e.g., x y Mn z (NCM) mixed NCAs with varied degree loss.

Costs, carbon footprint, and environmental impacts of lithium-ion batteries – From cathode active material synthesis to cell manufacturing and recycling

Applied Energy, Год журнала: 2023, Номер 353, С. 122132 - 122132

Опубликована: Окт. 23, 2023

Strong growth in lithium-ion battery (LIB) demand requires a robust understanding of both costs and environmental impacts across the value-chain. Recent announcements LIB manufacturers to venture into cathode active material (CAM) synthesis recycling expands process segments under their influence. However, little research has yet provided combined impact assessments several To address this gap, we provide cost assessment life cycle (LCA), covering CAM synthesis, cell manufacturing hydrometallurgy recycling. 1 kWh capacity (NMC811-C) is chosen as functional unit. Results for United States show total $94.5 kWh−1, global warming potential (GWP) 64.5 kgCO2eq (normalizing weighing 16 categories) 4.0 × 10−12 kWh−1. Material use contributes 69% 93% impacts. Energy demand, meanwhile, accounts 35% GWP. Initially, adds 5 10% costs, GWP, Including credits, recycled substitutes new virgin material, shows benefits Combined benefit most from (−75%), followed by (−44%) GWP (−37%). Further, present comprehensive dashboard which reveals how different scenarios, such as, using wind power instead grid electricity, influence segments. Switching low-carbon energy, example, reduces more than would. Also, our that or low scrap are suitable options if reduction objective.

Опубликована: Фев. 1, 2023

The huge amount of degraded NCM (LiNi0.5Co0.2Mn0.3O2) cathode materials from spent lithium-ion batteries is arising as a serious environmental issue well severe waste metal resources, and therefore, direct recycling them toward usable electrode again environmentally economically more attractive in contrast to present metallurgical treatments. In this work, we design robust two-step method for materials, which uses the aluminum impurity attached current collector supplement transition vacancies simultaneous elemental compensation structural restoration. This single-element strategy leads regeneration high-quality material with depressed cation disordering stabilized layered structure. Moreover, regenerated controllable Al doping delivered an outstanding electrochemical performance; specifically, capacity (158.6 mAh g-1), rate capability (91.6 g-1 at 5 C), cycling stability (89.6% retention after 200 cycles) are even comparable those fresh materials. as-established protocol has its chance simplifying industrial process
