Synergetic modulation on ionic association and solvation structure by electron-withdrawing effect for aqueous zinc-ion batteries

Proceedings of the National Academy of Sciences (2023)

Rui Wang Minjie Yao Min Yang Jiacai Zhu Jun Chen

Aqueous zinc-ion batteries are emerging as one of the most promising large-scale energy storage systems due to their low cost and high safety. However, Zn anodes often encounter the problems of Zn dendrite growth, hydrogen evolution reaction, and formation of by-products. Herein, we developed the low ionic association electrolytes (LIAEs) by introducing 2, 2, 2-trifluoroethanol (TFE) into 30 m ZnCl 2 electrolyte. Owing to the electron-withdrawing effect of -CF 3 groups in TFE molecules, in LIAEs, the Zn 2+ solvation structures convert from larger aggregate clusters into smaller parts and TFE will construct H-bonds with H 2 O in Zn 2+ solvation structure simultaneously. Consequently, ionic migration kinetics are significantly enhanced and the ionization of solvated H 2 O is effectively suppressed in LIAEs. As a result, Zn anodes in LIAE display a fast plating/stripping kinetics and high Coulombic efficiency of 99.74%. The corresponding full batteries exhibit an improved comprehensive performance such as high-rate capability and long cycling life.

Rationally designing a Ti₃C₂T_x/CNTs-Co₉S₈ heterostructure as a sulfur host with multi-functionality for high-performance lithium–sulfur batteries

Nanoscale (2022)

Tuo Xiao Youfang Zhang Wen Xi Rui Wang Yansheng Gong

Lithium-sulfur (Li-S) batteries have been regarded as potential next-generation batteries owing to their ultrahigh theoretical capacity and abundance of sulfur. However, polysulfide shuttling, poor electronic conductivity, and severe volume expansion limit their commercial prospects. In this work, we rationally constructed a 3D porous Ti3C2Tx/CNTs-Co9S8 heterostructure derived from a zeolite imidazole framework (ZIF)/Ti3C2Tx MXene composite via carbonization and subsequent sulfidation. In this 3D porous Ti3C2Tx/CNTs-Co9S8 heterostructure, the 3D porous Ti3C2Tx MXene structure can provide facilitated ion and electron transport, good structural stability, and polar bonds to anchor sulfur and polysulfides. The formed CNTs can enhance ion diffusion and electron transport. The Co9S8 nanoparticles can accelerate the conversion reaction of polysulfides to Li2S, which can further prevent polysulfide shuttling. The 3D porous structure can buffer the electrode volume change upon cycling. This rationally designed Ti3C2Tx/CNTs-Co9S8/S cathode exhibits a high initial capacity of 1389.8 mA h g-1 at 0.1C, good cyclic stability (730.7 mA h g-1 at 0.2C after 100 cycles), and excellent rate capacities (530.7 mA h g-1 at 1C). When the S loading was 2.5 mg cm-2, the Ti3C2Tx/CNTs-Co9S8/S cathode still exhibited a reversible capacity of 472.8 mA h g-1 at 0.5C after 300 cycles.

Constructing LiF‐Enriched Solid Electrolyte Interface on Graphene Arrays with Abundant Edges on Microscale Si‐C Anodes Toward High‐Energy Lithium‐Ion Batteries

Advanced Functional Materials (2024)

Ke Ge Zhenhong Wang Jie Liu Yongbiao Mu Rui Wang

Abstract Silicon (Si) anodes offer excellent lithium storage capacity for lithium‐ion batteries but face practical limitations due to significant volume expansion and low intrinsic electrical conductivity. These issues lead to side reactions that consume the electrolyte and impede ion‐electron transport, resulting in low areal loading (<2 mg cm⁻²) and restricted energy density. To address this, a scalable method is developed using spray drying of commercial graphite flakes (s‐Gr) and nanosilicon particles (n‐Si), followed by chemical vapor deposition to create microscale Si/C anodes (s‐Gr/n‐Si/VGs). Thin vertical graphene nanosheets (VGs) are grown on the surfaces and within the internal pores, forming a robust, micron‐sized Si/C spherical composite material. The VGs construct the conductive network, allowing the electrodes to operate at high areal loadings without pulverization and promoting LiF‐enriched solid electrolyte interphase for improved cycling stability. The s‐Gr/n‐Si/VGs maintain a capacity of 641.9 mAh g⁻¹ after 1000 cycles at 11.0 mg cm⁻², retaining 95.9% capacity. In pouch cells with NCM811 cathodes, the 5.0 Ah‐level cells achieved 80.0% capacity retention after 510 cycles at 1.0 C. This research provides a feasible pathway for manufacturing high‐performance, low‐cost, and scalable Si/C anodes suitable for high‐energy‐density lithium‐ion batteries.

Enhanced Electrochemical Performance of LiNi1/3Co1/3Mn1/3O2 at a High Cut-Off Voltage of 4.6 V by Li1.3Al0.3Ti1.7(PO4)3 Coating

Coatings (2022)

Ming Zhang Peng Zhang Weidong Wen Huanwen Wang Beibei He

At present, LiNi1/3Co1/3Mn1/3O2 (NCM) is a widely used material in the commercial market due to the easy control of the preparation process and usage environment. However, its capacity keeps fading when the cut-off voltage increases. In this research, an Li1.3Al0.3Ti1.7(PO4)3 (LATP) coating method is proposed to improve the cycle performance of LiNi1/3Co1/3Mn1/3O2 at a high cut-off voltage of 4.6 V. The battery prepared with LATP-modified NCM exhibits an increased discharge capacity retention of 92.37% after 100 cycles at 0.2C (1C = 200 mA g−1), while the bare NCM only presents 64.28%. Our results indicate that LATP-surface coating might be a useful method to increase the cycle stability of NCM and other high-capacity cathode materials.
