Isesengura rya Flame Retardant Isesengura hamwe nibyifuzo byo gutandukanya Bateri

Umukiriya akora batandukanya bateri, kandi ubuso butandukanya bushobora gutwikirwa urwego, mubisanzwe alumina (Al₂O₃) hamwe na binder nkeya. Ubu barashaka ubundi buryo bwa flame retardants kugirango basimbure alumina, nibisabwa bikurikira:

• Kurinda umuriro neza kuri 140 ° C.(urugero, kubora kurekura imyuka ya inert).
• Amashanyarazi ahamyeno guhuza nibice bya batiri.

Basabwe Flame Retardants hamwe nisesengura

1. Fosifore-Azote Synergistic Flame Retardants (urugero, Ammonium Polyphosphate Yahinduwe (APP) + Melamine)

Urwego:

• Inkomoko ya acide (APP) nisoko ya gaze (melamine) irahuza kugirango irekure NH₃ na N₂, igabanya umwuka wa ogisijeni hanyuma igakora char char yo guhagarika umuriro.
  Ibyiza:
• Fosifore-azote ikora irashobora kugabanya ubushyuhe bwo kubora (irashobora guhinduka ~ 140 ° C ikoresheje nano-sizing cyangwa formulaire).
• N₂ ni gaze ya inert; NH₃ ingaruka kuri electrolyte (LiPF₆) ikeneye gusuzuma.
  Ibitekerezo:
• Kugenzura ituze rya APP muri electrolytite (irinde hydrolysis muri aside fosifori na NH₃). Ipitingi ya silika irashobora kunoza ituze.
• Ikizamini cyo guhuza amashanyarazi (urugero, voltammetry cyclic) irakenewe.

2. Azote ishingiye kuri Azote (urugero, Sisitemu ya Azo)

Umukandida:Azodicarbonamide (ADCA) hamwe nabakora (urugero, ZnO).
Urwego:

• Ubushyuhe bwo kubora bushobora guhinduka kuri 140-150 ° C, kurekura N₂ na CO₂.
  Ibyiza:
• N₂ ni gaze ya inert nziza, itagira ingaruka kuri bateri.
  Ibitekerezo:
• Kugenzura ibicuruzwa (urugero, CO, NH₃).
• Microencapsulation irashobora guhuza neza ubushyuhe bwangirika.

3. Carbonate / Acide Ubushyuhe bwa Acide (urugero, Microencapsulated NaHCO₃ + Acide Source)

Urwego:

• Microcapsules yaturika kuri 140 ° C, bigatuma habaho reaction hagati ya NaHCO₃ na aside kama (urugero, aside citric) kugirango irekure CO₂.
  Ibyiza:
• CO₂ inert kandi ifite umutekano; ubushyuhe bwa reaction burashobora kugenzurwa.
  Ibitekerezo:
• Sodium ion irashobora kubangamira ubwikorezi bwa Li⁺; tekereza umunyu wa lithium (urugero, LiHCO₃) cyangwa uhagarika Na⁺ muri coating.
• Hindura uburyo bwo kubika ibyumba-ubushyuhe butajegajega.

Ubundi buryo bushoboka

• Ibyuma-ngengabihe (MOFs):urugero, ZIF-8 ibora ku bushyuhe bwo hejuru kugirango irekure gaze; Mugaragaza kuri MOFs hamwe nubushyuhe bwo kubora.
• Zirconium Fosifate (ZrP):Ikora inzitizi kumurongo wangirika, ariko irashobora gusaba nano-nini kugirango ubushyuhe bwangirika.

Ibyifuzo byubushakashatsi

1. Isesengura rya Thermogravimetric (TGA):Menya ubushyuhe bwangirika hamwe nuburyo bwo kurekura gaze.
2. Ikizamini cy'amashanyarazi:Suzuma ingaruka ku mikorere ya ionic, impedance interedance, hamwe nigikorwa cyo gusiganwa ku magare.
3. Kwipimisha Ikirimi cya Flame:urugero, ikizamini cyo gutwika gihagaritse, gupima ubushyuhe bwo kugabanuka (kuri 140 ° C).

Umwanzuro

Uwitekayahinduye fosifore-azote synergistic flame retardant (urugero, APP + melamine)irasabwa mbere kuberako iringaniza ya flame idahwitse hamwe nubushyuhe bwo kubora. Niba NH₃ igomba kwirindwa,sisitemu ya sisitemucyangwasisitemu ya microencapsulated CO₂-kurekura sisitemuNibishoboka. Iyemezwa ryikigereranyo ryicyiciro kirasabwa kwemeza amashanyarazi kandi bigahinduka.
