Uhlalutyo lwe-Flame Retardant kunye neeNgcebiso zeBattery Separator Coatings

Umthengi uvelisa abahluli bebhetri, kwaye umphezulu wokwahlula unokugqithwa ngomqolo, ngokuqhelekileyo i-alumina (Al₂O₃) kunye nenani elincinci le-binder. Ngoku bafuna ezinye iiretardants zomlilo zokutshintsha i-alumina, ngezi mfuno zilandelayo:

• Ukubuyiswa komlilo okusebenzayo kwi-140°C(umzekelo, ukubola ukukhulula iigesi ezingasebenziyo).
• Ukuzinza kwe-Electrochemicalkunye nokuhambelana namalungu ebhetri.

IiRetardants ezicetyiswayo zeFlame and Analysis

1. Phosphorus-Nitrogen Synergistic Retardants Flame (umz., Modified Ammonium Polyphosphate (APP) + Melamine)

Inkqubo:

• Umthombo we-Acid (APP) kunye nomthombo wegesi (i-melamine) i-synergize ukukhulula i-NH₃ kunye ne-N₂, i-oxygen diluting kunye nokwenza i-char layer ukuvimba amadangatye.
  Izinto eziluncedo:
• I-Phosphorus-nitrogen synergy inokwehlisa ubushushu bokubola (bulungiseka ukuya ku- ~140°C ngokusetyenziswa kwe-nano-size okanye ukwakheka).
• I-N₂ yigesi engasebenziyo; Impembelelo ye-NH₃ kwi-electrolyte (LiPF₆) ifuna uvandlakanyo.
  Iingqwalasela:
• Qinisekisa ukuzinza kwe-APP kwi-electrolytes (ugweme i-hydrolysis kwi-phosphoric acid kunye ne-NH₃). Ukwaleka kwe-silica kunokuphucula ukuzinza.
• Uvavanyo lokuhambelana kwe-Electrochemical (umzekelo, i-cyclic voltammetry) iyafuneka.

2. INitrogen-Based Flame Retardants (umzekelo, iAzo Compound Systems)

Umviwa:I-Azodicarbonamide (ADCA) ene-activators (umzekelo, i-ZnO).
Inkqubo:

• Iqondo lokushisa lokubola lilungelelaniswa kwi-140-150 ° C, ukukhulula i-N₂ kunye ne-CO₂.
  Izinto eziluncedo:
• I-N₂ yigesi efanelekileyo ye-inert, engenabungozi kwiibhetri.
  Iingqwalasela:
• Ukulawulwa kweemveliso (umzekelo, CO, NH₃).
• I-Microencapsulation inokumisela ngokuchanekileyo ubushushu bokubola.

3. Iinkqubo zeCarbonate/Acid Thermal Reaction Systems (umzekelo, iMicroencapsulated NaHCO₃ + Umthombo we-Acid)

Inkqubo:

• I-Microcapsules iphuka kwi-140 ° C, ibangela ukusabela phakathi kwe-NaHCO₃ kunye ne-organic acid (umzekelo, i-citric acid) ukukhulula i-CO₂.
  Izinto eziluncedo:
• I-CO₂ inert kwaye ikhuselekile; iqondo lobushushu impendulo iyalawuleka.
  Iingqwalasela:
• Iiyoni zesodium zinokuphazamisana nothutho lweLi⁺; qwalasela i-lithium salts (umzekelo, i-LiHCO₃) okanye i-immobilizing Na⁺ kwi-coating.
• Lungiselela i-encapsulation yozinzo lobushushu begumbi.

Olunye Ukhetho Olunokwenzeka

• IMetal-Organic Frameworks (MOFs):umzekelo, i-ZIF-8 ibola kumaqondo obushushu aphezulu ukukhulula igesi; isikrini se-MOFs kunye namaqondo obushushu obuthile ahambelanayo.
• IZirconium Phosphate (ZrP):Yenza umaleko wesithintelo ekuwohlokeni kwe-thermal, kodwa inokufuna i-nano-sizing ukuthoba iqondo lobushushu lokubola.

Iingcebiso zoMfuniselo

1. Uhlalutyo lweThermogravimetric (TGA):Ukumisela iqondo lokushisa lokubola kunye neempawu zokukhupha igesi.
2. Uvavanyo lwe-Electrochemical:Vavanya impembelelo kwi-ionic conductivity, impedance interfacial, kunye nokusebenza kwebhayisikile.
3. UVavanyo lweNkangala yedangatya:umz., uvavanyo lokutshisa oluthe nkqo, umlinganiselo wokushwabana kwe-thermal (kwi-140°C).

Ukuqukumbela

Ii-phosphorus-nitrogen synergistic flame retardant elungisiweyo (umzekelo, i-APP egqunyiweyo + ne-melamine)iyacetyiswa kuqala ngenxa yokubuyiswa komlilo kunye nobushushu bokubola. Ukuba i-NH₃ kufuneka iphetshwe,Iinkqubo ze-azo compoundokanyei-microencapsulated CO₂-release systemsziindlela ezinokusetyenziswa. Ukuqinisekiswa kovavanyo lwesigaba kuyacetyiswa ukuba kuqinisekiswe ukuzinza kwe-electrochemical kunye nokusebenza kwenkqubo.
