Degradable cellulose acetate/poly-l-lactic acid/halloysite nanotube composite nanofiber membranes with outstanding performance for gel polymer electrolytes

Abstract

The biodegraded cellulose acetate (CA)/poly-l-lactic acid (PLLA)/halloysite nanotube composite nanofiber membranes were fabricated for the preparation of gel polymer electrolytes (GPEs) used in lithium-ion batteries.

Cation Redistribution along the Spiral of Ni‐Doped Phyllosilicate Nanoscrolls: Energy Modelling and STEM/EDS Study

“…The outer and inner hydrosilicates surfaces saturated with OH‐groups can be modified by various organic compounds as well as be decorated by metallic or oxide phases ,. High aspect ratio affects on particles aggregation: entangling of nanotubes and nanoscrolls is used for production of self‐supported and composite membranes ,. Individual nanoscrolls demonstrate good mechanical properties,, which are appropriate for reinforcement of polymer composites.…”

“…[18,19] High aspect ratio affects on particles aggregation: entangling of nanotubes and nanoscrolls is used for production of self-supported and composite membranes. [20,21] Individual nanoscrolls demonstrate good mechanical properties, [22,23] which are appropriate for reinforcement of polymer composites. Change of Mg by a delement like Ni enhances magnetic properties of the particles.…”

Recent progress on biomass‐derived ecomaterials toward advanced rechargeable lithium batteries

“…However, owing to the insolubility in organic solvents, natural polymers are generally difficult to use directly as gel polymer skeletons to reserve organic liquid electrolytes in conventional Li batteries. Modification strategies through grafting or combining with other macromolecules have also been demonstrated . For instance, by combining starch with γ‐(2,3‐epoxypropoxy)propyltrimethoxysilane, organic electrolyte can be gelled via the chemical substitution reaction between ─OH groups and ─Si─(OCH 3 ) 3 (Figure A,B) .…”

“…Modification strategies through grafting or combining with other macromolecules have also been demonstrated. 51,[57][58][59][60][61][62][63] For instance, by combining starch with γ-(2,3-epoxypropoxy)propyltrimethoxysilane, organic electrolyte can be gelled via the chemical substitution reaction between ─OH groups and ─Si─(OCH 3 ) 3 (Figure 2A,B). 57 Recently, Dong et al reported a new kind of bio-based poly (methyl vinyl ether-alt-maleic anhydride) composite electrolyte layer supported by natural bacterial cellulose and demonstrated its effectiveness in Li metal anode protection.…”

Synergistically Suppressing Lithium Dendrite Growth by Coating Poly‐l‐Lactic Acid on Sustainable Gel Polymer Electrolyte

“…Nevertheless, its inherent brittleness, poor heat resistance, poor barrier properties, and slow crystallization rate largely restrict its application in LMBs. Thus, a proper polymer blend system comprising cellulosic materials and PLLA would enable good thermal properties and promote the transmission of Li ions …”
