Nitrogen-doped porous graphite with expanded interlayer distance as a high-performance anode for lithium-ion batteries

C Zhu, Qing Wen, Jiaxin Yao, Jinling Yin et autres

Abstract To solve the problem of slow ion transport kinetics in natural graphite anodes, which stems from its two-dimensional layered structure and narrow interlayer distance, N-doped porous graphite (N-Gr etch ) was prepared through a synergistic strategy of potassium hydroxide (KOH) etching …

Valorization of graphite tailings into high-value silicon-carbon anodes: A spray-drying strategy for superior lithium storage

Huibang Feng, Jing Zhao, Jiaxin Yao, Y F et autres

Abstract The large dimensional variation of silicon during lithiation/delithiation usually causes electrode pulverization and unstable cycling behavior, which restricts the use of silicon-based anodes in lithium-ion batteries. Herein, a graphite tailing-derived silicon-carbon anode was designed by using natural graphite spheronization tailings (NGST) …

In situ polymerized LATP/PAN-reinforced solid-state electrolyte for stable lithium-metal batteries

Fengda Yu, ZongBo Jiang, Jing Zhao, Jiaxin Yao et autres

The flammable liquid electrolyte (LE) in lithium metal batteries continuously undergoes side reactions with lithium metal, not only consuming active substances but also potentially triggering thermal runaway, thereby limiting the practical viability of these high-energy-density systems 1. Solid polymer electrolytes (SPEs), with …

Adsorption of fluoride on polyfunctional γ-AlOOH/EG composites: adsorption behavior and mechanism

Hang Sun, Jinling Yin, Jing Zhao, Guiling Wang et autres

Adsorption is commonly used for the treatment of fluoride-containing wastewater, a series of multifunctionalized EG/γ- AlOOH composite defluorination adsorbents was synthesized. Among these, the mesoporous D-A@EG exhibited an adsorption capacity (Qe) of 89.33 mg/g, which is 7.30 times higher than that of …

Ni-decorated porous dendritic Cu film on Cu foam for enhanced hydrazine oxidation catalysis

R. Liu, Yuting Luan, Shuang Sheng, Jinling Yin

Two major challenges limit the widespread use of direct hydrazine fuel cells (DHFCs): slow hydrazine oxidation reaction (HzOR) kinetics and the reliance on expensive noble-metal catalysts. To overcome these limitations, a Ni-Cu film/Cu foam (CF) electrode was developed through a two-stage electrochemical …
