Biopolymer‐Based Flame Retardants and Flame‐Retardant Materials

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 8, 2025

Abstract Polymeric materials featuring excellent flame retardancy are essential for applications requiring high levels of fire safety, while those based on biopolymers highly favored due to their eco‐friendly nature, sustainable characteristics, and abundant availability. This review first outlines the pyrolysis behaviors biopolymers, with particular emphasis naturally occurring ones derived from non‐food sources such as cellulose, chitin/chitosan, alginate, lignin. Then, strategies chemical modifications flame‐retardant purposes through covalent, ionic, coordination bonds presented compared. The is placed advanced methods introducing biopolymer‐based retardants into polymeric matrices fabricating materials. Finally, challenges sustaining current momentum in utilization further discussed.

2D Covalent Organic Framework Covalently Anchored with Carbon Nanotube as High‐Performance Cathodes for Lithium and Sodium‐Ion Batteries

Small, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 3, 2024

Covalent organic frameworks (COFs), featuring structural diversity, permanent porosity, and functional versatility, have emerged as promising electrode materials for rechargeable batteries. To date, amorphous polymer, COF, or their composites are mostly explored in lithium-ion batteries (LIBs), while research other alkali metal ion is still infancy. This can be due to the challenges that arise from large volume changes, slow diffusion kinetics, inefficient active site utilization by Na

Restraining Lattice Oxygen Escape by Bioinspired Antioxidant Enables Thermal Runaway Prevention in Ni−Rich Cathode Based Lithium−Ion Batteries

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: 14(31)

Published: May 21, 2024

Abstract Ni−rich cathodes are hopeful materials for advanced lithium−ion batteries (LIBs) due to high capacity. Nonetheless, the chemical crosstalk triggered by reactive oxygen (O * ) represents a critical factor in thermal runaway (TR). Currently, there few effective means prevent this parasitic reaction. Here, inspired O scavenging effect of β−carotene living organisms, it is innovatively identified that can impede TR restraining escape during decomposition nickel−rich cathodes. Using LiNi 0.6 Co 0.2 Mn 2 as model and extending higher nickel content (LiNi 0.8 0.1 , 0.9 0.05 ), demonstrated undergo an situ copolymerization reaction trapping thereby attenuating crosstalk. Additionally, generated copolymer also adjust band center 2p orbitals delithiated cathode, alleviating charge compensation behavior anions, thus delaying phase transition charged . As result, trigger temperature NCM811∣Graphite pouch cell increased from 131.0 195.0 °C maximum reduced 657.8 412.4 °C. This work introduces new simple strategy designing functional additives block TR, offering promising avenue advancing safety LIBs.
