Ukuhlaziywa Kwe-Flame Retardant kanye Nezincomo Zezimbozo Ze-Battery Separator

Ikhasimende likhiqiza izihlukanisi zamabhethri, futhi indawo yokuhlukanisa ingambozwa ngesendlalelo, ngokuvamile i-alumina (Al₂O₃) ngenani elincane le-binder. Manje bafuna ezinye izinto zokuvimbela umlilo ukuze zithathe indawo ye-alumina, ngalezi zidingo ezilandelayo:

• Ukushisa okusebenzayo komlilo ku-140°C(isib., ukubola ukuze kukhishwe amagesi angasebenzi).
• Ukuzinza kwe-electrochemicalkanye nokuhambisana nezingxenye zebhethri.

Izinto Ezivimbela Umlilo Ezinconyiwe Nokuhlaziywa

1. Izinto Ezivimbela Umlilo Ezihambisanayo ze-Phosphorus-Nitrogen (isb., i-Modified Ammonium Polyphosphate (APP) + i-Melamine)

Indlela yokusebenza:

• Umthombo we-asidi (i-APP) kanye nomthombo wegesi (i-melamine) kuyasebenzisana ukuze kukhishwe i-NH₃ kanye ne-N₂, kuncibilikiswe umoya-mpilo futhi kwakhiwe ungqimba lwe-char ukuze kuvinjwe amalangabi.
  Izinzuzo:
• Ukusebenzisana kwe-phosphorus-nitrogen kunganciphisa izinga lokushisa lokubola (okulungiselelwa ku-~140°C nge-nano-size noma i-formulation).
• I-N₂ iyigesi engasebenzi; umthelela we-NH₃ ku-electrolyte (LiPF₆) udinga ukuhlolwa.
  Izinto okufanele uzicabangele:
• Qinisekisa ukuzinza kwe-APP kuma-electrolyte (gwema i-hydrolysis ibe yi-phosphoric acid kanye ne-NH₃). Ukuhlanganiswa kwe-silica kungathuthukisa ukuzinza.
• Ukuhlolwa kokuhambisana kwe-electrochemical (isb., i-cyclic voltammetry) kuyadingeka.

2. Izinto Ezivimbela Umlilo Ezisekelwe Ku-nitrogen (isb., Izinhlelo Ze-Azo Compound)

Umuntu ozongenela ukhetho:I-Azodicarbonamide (ADCA) eneziqalisi (isib., i-ZnO).
Indlela yokusebenza:

• Izinga lokushisa lokubola elilungiseka libe ngu-140–150°C, likhipha i-N₂ kanye ne-CO₂.
  Izinzuzo:
• I-N₂ iyigesi engasebenzi kahle, engenangozi kumabhethri.
  Izinto okufanele uzicabangele:
• Imikhiqizo engaphansi kokulawula (isb., i-CO, i-NH₃).
• I-Microencapsulation ingalungisa ngokunembile izinga lokushisa lokubola.

3. Izinhlelo Zokusabela Kokushisa zeCarbonate/Acid (isb., i-Microencapsulated NaHCO₃ + Umthombo we-Acid)

Indlela yokusebenza:

• Ama-microcapsule ayaqhuma ku-140°C, okubangela ukusabela phakathi kwe-NaHCO₃ kanye ne-organic acid (isb., i-citric acid) ukuze kukhishwe i-CO₂.
  Izinzuzo:
• I-CO₂ ayisebenzi futhi iphephile; izinga lokushisa lokusabela liyalawuleka.
  Izinto okufanele uzicabangele:
• Ama-ion e-sodium angaphazamisa ukuthuthwa kwe-Li⁺; cabanga ngosawoti we-lithium (isb., i-LiHCO₃) noma ukuvimba i-Na⁺ ekumbozweni.
• Lungiselela ukufakwa kwe-encapsulation ukuze kuqiniswe izinga lokushisa legumbi.

Ezinye Izinketho Ezingenzeka

• Izinhlaka Zensimbi Nezinto Eziphilayo (ama-MOF):isib., i-ZIF-8 iyabola emazingeni okushisa aphezulu ukuze ikhiphe igesi; ivikela ama-MOF anezinga lokushisa elifanayo lokubola.
• I-Zirconium Phosphate (ZrP):Yakha ungqimba lwesithiyo lapho ibola ngokushisa, kodwa ingadinga ubukhulu obuncane ukuze yehlise izinga lokushisa lokubola.

Izincomo Zokuhlola

1. Ukuhlaziywa kwe-Thermogravimetric (TGA):Nquma izinga lokushisa lokubola kanye nezakhiwo zokukhishwa kwegesi.
2. Ukuhlolwa Kwamakhemikhali:Hlola umthelela ekuqhutshweni kwe-ionic, impedance ye-interfacial, kanye nokusebenza kokujikeleza.
3. Ukuhlolwa Kokuvinjelwa Komlilo:isib., ukuhlolwa kokushisa okuqondile, ukulinganiswa kokushisa (ku-140°C).

Isiphetho

Ii-phosphorus-nitrogen synergistic flame retardant eguquliwe (isb., i-APP ehlanganisiwe + i-melamine)Kunconywa kuqala ngenxa yokulinganisela kokushisa komlilo kanye nokushisa okulungisekayo kokubola. Uma i-NH₃ kumele igwenywe,izinhlelo ze-azo compoundnomaizinhlelo zokukhulula i-CO₂ ezincane ezifakwe emaphakethenikuyizindlela ezingasebenza. Ukuqinisekiswa kokuhlolwa okunezigaba kuyelulekwa ukuqinisekisa ukuzinza kwe-electrochemical kanye nokwenzeka kwenqubo.
