Incorporating Ionic Liquid 1‐Ethyl‐3‐Methylimidazolium Bromide Into PVA‐LiAc–Based Solid Polymer Electrolytes to Achieve Advanced Solid‐State Lithium‐Ion Batteries

Journal of Applied Polymer Science, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 18, 2025

ABSTRACT Solid polymer electrolytes (SPEs) serve as both separators and electrolytes, enhancing the safety of energy storage devices by eliminating liquid components. In this study, we present SPEs prepared from a blend polyvinyl alcohol (PVA), lithium acetate (LiAc), ionic 1‐ethyl‐3‐methylimidazolium bromide ([EMIm]Br). This combination prevents leakage issues common with addresses low conductivity typical solid electrolytes. The are easy to produce, highly transparent, thermally stable up 271°C, exhibit high conductivity, values 2.21 × 10 −5 S cm −1 when 40% [EMIm]Br is added PVA/10% LiAc membrane. Additionally, composition demonstrates mechanical strength 20.40 MPa an elongation 485.12%. These findings highlight strong potential [EMIm]Br–based for lithium‐ion batteries.

Research Progresses on Nano-Structured Silicon-Based Materials as Anode for Lithium-Ion Batteries

Materials, Journal Year: 2025, Volume and Issue: 18(4), P. 830 - 830

Published: Feb. 14, 2025

Silicon-based materials are considered the most promising next-generation anode for lithium-ion batteries due to their high theoretical specific capacity, rich reserves, and advantages of low discharge potential. However, significant volume expansion silicon during cycling process leads detachment active substances loss electrical contact between current collector, ultimately resulting in a decline battery performance. Nanostructured anodes have surface area, short diffusion path, ability effectively alleviate electrode material circulation. Therefore, how rationally design nanostructured silicon-based is currently one research hotspots. This article first reviews evaluates disadvantages microstructured nano-structured rate performance, discusses cycle stability volumetric energy density, summarizes lithium storage mechanism materials, with focus on influence some silicon/carbon composites conductive polymers silicon/metal electrochemical properties materials. Finally, suggestions prospects future development proposed.

Anisotropic Conductivity and Mechanical Strength Enhancements in Gel Polymer Electrolyte Films by Hot Pressing

Materials, Journal Year: 2025, Volume and Issue: 18(8), P. 1751 - 1751

Published: April 11, 2025

Gel polymer electrolyte (GPE) with a matrix swollen in liquid electrolytes offers several advantages over conventional electrolytes, including no leakage, lightweight properties, and high reliability. While poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)-based GPEs show promise for lithium-ion batteries, their practical application is hindered by the intrinsic trade-off between ionic conductivity mechanical robustness PVDF systems. Typical strategies relying on excessive plasticizers (e.g., liquids) compromise integrity. Here, we propose novel hot-pressing-induced recrystallization strategy to synergistically enhance both anisotropic puncture strength PVDF-based GPE films. By blending controlled amounts of 1-hexyl-3-methylimidazolium chloride ([HMIM]Cl), followed solution casting hot pressing, achieve microstructural reorganization that dramatically improves through-thickness ion transport performance. Crucially, hot-pressed only 25 wt% [HMIM]Cl exhibits 12.5-fold increase (reaching 4.7 × 10−4 S/cm) compared its solution-cast counterparts. Remarkably, this formulation surpasses PVDF-HFP composites higher content (35 wt%, 1.7 S/cm), demonstrating performance optimization conductivity. What more, piercing perpendicular film after pressing increased 42% film. This work establishes scalable processing route break conductivity–strength dichotomy GPEs, offering critical insights designing high-performance electrolytes.

Mo-Doped Na4Fe3(PO4)2P2O7/C Composites for High-Rate and Long-Life Sodium-Ion Batteries

Materials, Journal Year: 2024, Volume and Issue: 17(11), P. 2679 - 2679

Published: June 1, 2024

Na4Fe3(PO4)2P2O7/C (NFPP) is a promising cathode material for sodium-ion batteries, but its electrochemical performance heavily impeded by low electronic conductivity. To address this, pure-phase Mo6+-doped Na4Fe3−xMox(PO4)2P2O7/C (Mox-NFPP, x = 0, 0.05, 0.10, 0.15) with the Pn21a space group successfully synthesized through spray drying and annealing methods. Density functional theory (DFT) calculations reveal that Mo6+ doping facilitates transition of electrons from valence to conduction band, thus enhancing intrinsic electron conductivity Mox-NFPP. With an optimal level Mo0.10-NFPP exhibits lower charge transfer resistance, higher diffusion coefficients, superior rate performance. As result, offers initial discharge capacity up 123.9 mAh g−1 at 0.1 C, nearly reaching theoretical capacity. Even high 10 it delivers 86.09 g−1, maintaining 96.18% after 500 cycles. This research presents new straightforward strategy enhance NFPP materials batteries.
