Flame-retardant GPEs were prepared by in-situ thermal polymerization for quasi-state sodium ion batteries. The as-prepared flexible and self-supported GPE, PGT32-5%, delivers a high ionic conductivity of 9.1 × 10 -4 S cm −1 at room temperature and a high oxidation degradation potential of 4.8 V vs. Na + /Na.
Every year, fires kill more than 3,000 people, injure more than 20,000, and result in property damages exceeding an estimated $11 billion in the United States alone (Karter 2001) re incidence has dropped over the past 25 years, which is partly because of the fire prevention policies requiring the presence of flame retardant chemicals in many …
Preparation of CPCM containing PEG, EG, MXene and FR (APP:ZHS = 2:1) was achieved using a melt blending technique, as illustrated in Fig. 1, the pure PEG was put into a beaker in an oven at 100 C for 30 min until it melted, followed by addition of predetermined amount of MXene and EG with stirring for 30 min, the flame retardant …
Flame retardants (FRs) have received greater attention over time due to their occurrence in environmental media and biological matrices 1,2.Certain FRs have been classified as persistent ...
The APP binder employed here not only improves the polysulfide adsorption capability but also endows sulfur electrode with flame-retardant properties to effectively improve the safety of Li–S batteries. To demonstrate the flame-retardant property of APP, sulfur cathodes with APP and PVDF binders were exposed to a direct …
Because of the flame retardant properties as well as higher ionic conductivity and electrochemical stability, the battery with [Bmim]PF 6-5% exhibits excellent performance. Compared to CE, the IIL-E with 5% of [Bmim]PF 6 has a higher initial discharge capacity and a higher capacity retention rate after the 100th cycle of charge …
Rechargeable batteries that can operate at elevated temperatures (>70 °C) with high energy density are long-awaited for industrial applications including mining, grid stabilization, naval, aerospace, and medical devices. However, the safety, cycle life, energy density, and cost of the available high-temperature battery technologies remain an …

Due to their extraordinary theoretical energy density, high specific capacity, and environment-friendly nature, lithium–sulfur batteries (LSBs) have been considered the most promising candidates for energy storage. However, in recent years, fire hazards and explosions caused by batteries have seriously endan Journal of Materials Chemistry A …
The advancement of lithium-based batteries has spurred anticipation for enhanced energy density, extended cycle life and reduced capacity degradation. However, these benefits are accompanied by potential risks, such as thermal runaway and explosions due to higher energy density. Currently, liquid organic electrolytes are the predominant …
The separator plays a significant role in influencing electrochemical performances and monitoring battery safety in lithium-ion batteries. Nevertheless, suffered by commercial polyolefin separator intrinsic drawbacks of intolerable electrolyte affinity, low ionic conductivity, poor thermal stability and terrible flammability with large thermal …
