Abstract Hard carbon (HC), as a promising anode material for sodium ion batteries, its sluggish diffusion performance hinders further improvement of electrochemical performance. In the preparation process HC materials, screening and treatment precursors can optimize structure morphology products, affecting Here, we use peptone precursor prepare flaky N-doped (PFNC) through one-step annealing method. Benefitting from this structure, prepared PNFC delivers specific capacity 315.5 mAh g −1 at current density 20 mA with excellent rate cyclic stability. This work proves that is valuable precursor, opening new avenue application development HC.

Turning waste tyres into carbon electrodes for batteries: Exploring conversion methods, material traits, and performance factors

Carbon Energy, Год журнала: 2024, Номер unknown

Опубликована: Июнь 7, 2024

Abstract Waste tyres (WTs) are a major global issue that needs immediate attention to ensure sustainable environment. They often dumped in landfills or incinerated open environments, which leads environmental pollution. However, various thermochemical conversion methods have shown promising results as treatment routes tackle the WT problem while creating new materials for industries. One such material is char, has properties comparable those of carbon used an active electrode batteries. Therefore, systematic review approaches convert WTs into applications was conducted. The shows pretreatment processes, process routes, and operating parameters affect derived its respective electrochemical performance. WT‐derived potential yield high specific capacity greater than traditional graphite (372 mAh g −1 ) commonly lithium‐ion Finally, outlines challenges well opportunities future research directions from WTs.

Coupling Ferricyanide/Ferrocyanide Redox Mediated Recycling Spent LiFePO₄ with Hydrogen Production

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(10)

Опубликована: Янв. 16, 2024

Abstract Replacing the oxygen evolution reaction with thermodynamically more favorable alternative oxidation reactions offers a promising to reduce energy consumption of hydrogen production. However, questions remain regarding economic viability for industrial‐scale Here, we propose an innovative cost‐effective, environment‐friendly and energy‐efficient strategy simultaneous recycling spent LiFePO 4 (LFP) batteries production by coupling LFP‐assisted ferricyanide/ferrocyanide ([Fe(CN) 6 ] 4− /[Fe(CN) 3− ) redox reaction. The onset potential electrooxidation [Fe(CN) is low at 0.87 V. Operando Raman UV/Visible spectroscopy confirm that presence LFP in electrolyte allows rapid reduction , thereby completing cycle as well facilitating conversion into LiOH ⋅ H 2 O FePO . electrolyzer consumes 3.6 kWh electricity per cubic meter produced 300 mA cm −2 which 43 % less than conventional water electrolysis. Additionally, this pathway not only minimizes chemical prevents secondary pollution but also presents significant benefits.
