Flame Retardant Analysis uye Mazano eBattery Separator Coatings

Mutengi anogadzira zvinoparadzanisa bhatiri, uye nzvimbo yekuparadzanisa inogona kuputirwa nedhiri, kazhinji alumina (Al₂O₃) ine hushoma hwebinder. Ivo zvino vanotsvaga dzimwe nzira dzinodzosa moto kuti dzitsive alumina, nezvinodiwa zvinotevera:

• Kushanda kunonoka kwemurazvo pa140°C(semuenzaniso, kuora kuburitsa gasi inert).
• Electrochemical kugadzikanauye kuenderana nemidziyo yebhatiri.

Yakakurudzirwa Flame Retardants uye Analysis

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

Mechanism:

• Acid sosi (APP) uye gasi sosi (melamine) synergize kuburitsa NH₃ uye N₂, kunyungudutsa okisijeni uye kugadzira char layer yekuvhara marimi.
  Zvakanakira:
• Phosphorus-nitrogen synergy inogona kudzikisira tembiricha yekuora (inochinjika kusvika ~140°C kuburikidza nano-kukura kana kuumbwa).
• N₂ igesi inert; NH₃ kukanganisa pa electrolyte (LiPF₆) inoda kuongororwa.
  Zvinotarisirwa:
• Simbisa kugadzikana kweAPP mu electrolytes (dzivisa hydrolysis mu phosphoric acid uye NH₃). Silica coating inogona kuvandudza kugadzikana.
• Electrochemical kuenderana kuyedzwa (semuenzaniso, cyclic voltammetry) inodiwa.

2. Nitrogen-Based Flame Retardants (semuenzaniso, Azo Compound Systems)

Mumiriri:Azodicarbonamide (ADCA) ine activators (semuenzaniso, ZnO).
Mechanism:

• Kuora tembiricha inogadziriswa kusvika 140-150 ° C, ichiburitsa N₂ uye CO₂.
  Zvakanakira:
• N₂ igasi rakanakira inert, risingakuvadzi kumabhatiri.
  Zvinotarisirwa:
• Kudzora byproducts (semuenzaniso, CO, NH₃).
• Microencapsulation inogona kunyatsogadzirisa tembiricha yekuora.

3. Carbonate/Acid Thermal Reaction Systems (semuenzaniso, Microencapsulated NaHCO₃ + Acid Source)

Mechanism:

• Microcapsules inoputika pa 140 ° C, zvichikonzera kugadzikana pakati peNaHCO₃ uye organic acid (eg, citric acid) kusunungura CO₂.
  Zvakanakira:
• CO₂ inert uye yakachengeteka; reaction tembiricha inodzoreka.
  Zvinotarisirwa:
• Sodium ions inogona kukanganisa Li⁺ kutakura; funga lithium munyu (semuenzaniso, LiHCO₃) kana immobilizing Na⁺ mukupfeka.
• Gadzirisa encapsulation yekamuri-tembiricha kugadzikana.

Zvimwe Zvingabvira Sarudzo

• Metal-Organic Frameworks (MOFs):semuenzaniso, ZIF-8 inoora pakupisa kwakanyanya kuburitsa gasi; chidzitiro cheMOFs chine tembiricha yekuparara inoenderana.
• Zirconium Phosphate (ZrP):Inoumba chipingamupinyi chinodzivirira pakuora kwemafuta, asi zvingada nano-sizing kudzikisa tembiricha yekuora.

Mazano ekuedzwa

1. Thermogravimetric Analysis (TGA):Sarudza decomposition tembiricha uye gasi kuburitsa zvivakwa.
2. Electrochemical Testing:Ongorora maitiro pane ionic conductivity, interfacial impedance, uye kuita bhasikoro.
3. Flame Retardancy Testing:semuenzaniso, vertical burning test, thermal shrinkage measurement (pa140°C).

Mhedziso

Theyakagadziridzwa phosphorus-nitrogen synergistic flame retardant (semuenzaniso, yakavharwa APP + melamine)inokurudzirwa kutanga nekuda kwekunonoka kwayo kwemurazvo uye tembiricha yekuora. Kana NH₃ ichifanirwa kudzivirirwa,azo compound systemskanamicroencapsulated CO₂-kusunungura masisitimudzimwe nzira dzinoshanda. Kusimbiswa kwechiyedzo kunorayirwa kuti kuve nechokwadi chekugadzikana kwe electrochemical uye kugona kwekuita.
