Rational design of dual-ion doped cobalt-free Li-rich cathode materials for enhanced cycle stability of lithium-ion pouch cell batteries.

The synergistic effect of single-crystal structure and dual doping in Li-rich cobalt-free cathode materials was thoroughly investigated. Lithium-ion pouch cells employing Sb/Sn doped LiMnNiO and graphite exhibited a specific capacity of 191.01 mA h g at 1C rate and exceptionally stable performance upon cycling, with capacity retention of 87.

Advancing lithium-sulfur battery efficiency: utilizing a 2D/2D g-CN@MXene heterostructure to enhance sulfur evolution reactions and regulate polysulfides under lean electrolyte conditions.

Lithium-sulfur batteries (LSBs) show promise for achieving a high energy density of 500 W h kg, despite challenges such as poor cycle life and low energy efficiency due to sluggish redox kinetics of lithium polysulfides (LiPSs) and sulfur's electronic insulating nature. We present a novel 2D TiC Mxene on a 2D graphitic carbon nitride (g-CN) heterostructure designed to enhance LiPS conversion kinetics and adsorption capacity. In a pouch cell configuration with lean electrolyte conditions (∼5 μL mg), the g-CN-Mx/S cathode exhibited excellent rate performance, delivering ∼1061 mA h g at C/8 and retaining ∼773 mA h g after 190 cycles with a Coulombic efficiency (CE) of 92.

Regioselective Protection and Deprotection of Nanocellulose Molecular Design Architecture: Robust Platform for Multifunctional Applications.

Regioselectively substituted nanocellulose was synthesized by protecting the primary hydroxyl group. Herein, we took advantage of the different reactivities of primary and secondary hydroxyl groups to graft large capping structures. This study mainly focuses on regioselective installation of trityl protecting groups on nanocellulose chains.

One-pot fabrication of flexible and luminescent nanofilm by in-situ radical polymerization of vinyl carbazole on nanofibrillated cellulose.

Photoresponsive functionalized nanofilms were prepared via radical polymerization of carbazole units on a nanofibrillated cellulose (NFC) backbone via one-pot procedure. Herein, NFC was functionalized with active carbazole units as pendant organic moieties. The nanofilms were characterized by UV-vis and fluorescence spectroscopy, Fourier transformed infrared (FTIR) and Raman spectroscopy, C NMR and proton NMR spectra, contact angle analysis, mechanical testing, and scanning electron microscopy (SEM).

Non-Isothermal Crystallization Behavior and Thermal Properties of Polyethylene Tuned by Polypropylene and Reinforced with Reduced Graphene Oxide.

This research work is the first to report thermal stability, heat deformation resistance, and crystallization behavior of a Polyethylene (PE)-based biphasic polyolefin system reinforced with Reduced Graphene Oxide (RGO), which was obtained through Graphene Oxide (GO) chemical reduction. Polypropylene (PP) represented the polymeric dispersed phase. A strategic PE/PP/RGO manufacturing procedure was employed to thermodynamically localize RGO at the PE/PP interface, as confirmed by Transmission Electron Microscopy (TEM), bringing a uniform micro phase dispersion into the macro phase.
