Falanqaynta Dib-u-Celinta Ololka iyo Talooyinka loogu talagalay Dahaarka Kala-duwayaasha Batteriga

Macmiilku wuxuu soo saaraa kala-soocida baytariga, dusha sare ee kala-soocida waxaa lagu dahaadhay karaa lakab, sida caadiga ah alumina (Al₂O₃) oo leh qadar yar oo binder ah. Hadda waxay raadiyaan dab-demis kale oo ay ku beddelaan alumina, oo leh shuruudaha soo socda:

• Dib u dhac ku yimaadda ololka 140°C(tusaale, qudhuntay si loo sii daayo gaas aan shaqaynayn).
• Degganaanshaha korantadaiyo waafaqsanaanta qaybaha batteriga.

Dib-u-dhigayaasha Ololka lagu taliyay iyo Falanqaynta

1. Fosfooraska-Nitrogen Dib-u-celinta Ololka Isku-dhafka ah (tusaale, Ammonium Polyphosphate (APP) + Melamine oo la beddelay)

Farsamaynta:

• Ilaha aysiidhka (APP) iyo isha gaaska (melamine) waxay is kaashadaan si ay u sii daayaan NH₃ iyo N₂, oo la milo ogsijiinta iyo samaynta lakabka dhuxusha si uu u xannibo ololka.
  Faa'iidooyinka
• Isku-dhafka Fosfooraska-nitrogen wuxuu hoos u dhigi karaa heerkulka burburka (la hagaajin karo ~ 140 ° C iyada oo loo marayo nano-sizing ama qaabaynta).
• N₂ waa gaas aan shaqayn; Saamaynta NH₃ ee elektrolytka (LiPF₆) waxay u baahan tahay qiimayn.
  Tixgelin:
• Xaqiiji xasilloonida APP ee elektirolytka (ka fogow hydrolysis galay phosphoric acid iyo NH₃). Dahaarka silica ayaa laga yaabaa inuu hagaajiyo xasilloonida.
• Tijaabada ku-habboonaanta korantada (tusaale, voltammetry cyclic) ayaa loo baahan yahay.

2. Dib-u-celiyayaasha ololka ku salaysan Nitrojiin (tusaale, Nidaamyada Isku-dhafka Azo)

Musharax:Azodicarbonamide (ADCA) oo leh hawl-wadeenayaal (tusaale, ZnO).
Farsamaynta:

• Heerkulka burburka oo lagu hagaajin karo 140-150°C, isagoo sii deynaya N₂ iyo CO₂.
  Faa'iidooyinka
• N₂ waa gaas aan shaqaynayn oo ku habboon, oo aan waxyeello u lahayn baytariyada.
  Tixgelin:
• Xakamaynta badeecadaha (tusaale, CO, NH₃).
• Microencapsulation waxay si sax ah u hagaajin kartaa heerkulka burburka.

3. Nidaamyada Falcelinta Kulaylka Kaarboonate/Aashitada (tusaale, NaHCO₃ Microencapsulated NaHCO₃ + Isha Asiidhka)

Farsamaynta:

• Microcapsules ayaa dilaaca 140°C, taasoo kicinaysa falcelinta u dhaxaysa NaHCO₃ iyo organic acid (tusaale, citric acid) si loo sii daayo CO₂.
  Faa'iidooyinka
• CO₂ waa mid aan firfircoonayn oo ammaan ah; heerkulka falcelinta waa la xakameyn karaa.
  Tixgelin:
• Iions Sodium waxay faragelin kartaa gaadiidka Li⁺; Tixgeli cusbada lithium-ka (tusaale, LiHCO₃) ama Na⁺ ma-dhaqaajinaysa dahaarka.
• U wanaaji koobabaynta xasilloonida heerkulka qolka.

Ikhtiyaarada kale ee suurtagalka ah

• Qaab-dhismeedka Birta-Organic (MOFs):tusaale, ZIF-8 waxay ku qudhuntaa heerkulka sare si uu u sii daayo gaaska; shaashada MOF-yada leh heerkulka burburka ee u dhigma.
• Zirconium Fosfate (ZrP):Waxay samaysaa lakabka xannibaadda marka kulaylku xumaado, laakiin waxa laga yaabaa inuu u baahdo nano-cabbir si loo yareeyo heerkulka burburka.

Talooyin tijaabo ah

1. Falanqaynta Thermogravimetric (TGA):Go'aami heerkulka burburay iyo sifooyinka sii daynta gaaska.
2. Tijaabada Electrochemical:Qiimee saamaynta ay ku leedahay hab-dhaqanka ionic, waji gabagabada, iyo waxqabadka baaskiilka.
3. Tijaabada Dib u Dhaca Ololka:tusaale, tijaabada gubashada tooska ah, cabbirka kulaylka yaraynta (heerka 140°C).

Gabagabo

TheFosfooraska-nitrojiinka dab-demiska oo wax laga beddelay (tusaale, dahaarka leh APP + melamine)marka hore waxaa lagula talinayaa iyadoo ay ugu wacan tahay dib-u-dhaca ololka oo dheellitiran iyo heer kulka qudhunka ee la hagaajin karo. Haddii NH₃ ay tahay in laga fogaado,nidaamyada isku dhafan azoamaNidaamyada CO₂-ku-xiran ee lagu sii daayowaa beddelaad macquul ah. Xaqiijin tijaabo ah oo weji leh ayaa lagula talinayaa si loo hubiyo xasilloonida korantada iyo habka suurtogalka ah.
