Kuwunika kwa Flame Retardant ndi Malangizo a Zopaka Zolekanitsa Battery

Makasitomala amatulutsa zolekanitsa mabatire, ndipo cholekanitsa pamwamba pake chimakutidwa ndi wosanjikiza, nthawi zambiri alumina (Al₂O₃) yokhala ndi zomangira pang'ono. Tsopano amafunafuna njira zina zochepetsera malawi kuti alowe m'malo mwa alumina, ndi zofunika izi:

• Kuchepetsa mphamvu yamoto pa 140 ° C(mwachitsanzo, kuwola kuti atulutse mpweya woipa).
• Kukhazikika kwa Electrochemicalndi kuyanjana ndi zigawo za batri.

Analimbikitsa Flame Retardants ndi Analysis

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

Njira:

• Gwero la asidi (APP) ndi gwero la gasi (melamine) zimagwirizanitsa kuti zitulutse NH₃ ndi N₂, kusungunula mpweya ndi kupanga char layer kuti atseke malawi.
  Ubwino:
• Phosphorus-nitrogen synergy imatha kutsitsa kutentha kwapang'onopang'ono (kusinthika kufika ~140°C kudzera mu nano-size kapena kupanga).
• N₂ ndi mpweya wochepa; NH₃ kukhudzidwa kwa electrolyte (LiPF₆) kumafunika kuunika.
  Zoganizira:
• Tsimikizirani kukhazikika kwa APP mu ma electrolyte (peŵani hydrolysis kukhala phosphoric acid ndi NH₃). Kupaka silika kungapangitse kukhazikika.
• Kuyesa kaphatikizidwe ka Electrochemical (mwachitsanzo, cyclic voltammetry) ndikofunikira.

2. Nayitrojeni-Motengera Flame Retardants (monga, Azo Compound Systems)

Wosankhidwa:Azodicarbonamide (ADCA) yokhala ndi ma activator (mwachitsanzo, ZnO).
Njira:

• Kutentha kwa kuwonongeka kosinthika mpaka 140-150 ° C, kutulutsa N₂ ndi CO₂.
  Ubwino:
• N₂ ndi gasi woyenera, wopanda vuto kwa mabatire.
  Zoganizira:
• Control byproducts (mwachitsanzo, CO, NH₃).
• Microencapsulation imatha kusintha kutentha kwa kuwonongeka.

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

Njira:

• Ma Microcapsules amaphulika pa 140 ° C, kumayambitsa kugwirizana pakati pa NaHCO₃ ndi organic acid (mwachitsanzo, citric acid) kuti amasule CO₂.
  Ubwino:
• CO₂ ndi inert komanso yotetezeka; kachitidwe kutentha ndi controlable.
  Zoganizira:
• Ma ions a sodium amatha kusokoneza mayendedwe a Li⁺; ganizirani za mchere wa lithiamu (mwachitsanzo, LiHCO₃) kapena kusasunthika kwa Na⁺ mu zokutira.
• Konzani encapsulation kuti chipinda chikhale chokhazikika.

Zina Zotheka

• Zitsulo-Organic Frameworks (MOFs):mwachitsanzo, ZIF-8 imawola pa kutentha kwambiri kuti itulutse mpweya; chophimba cha ma MOF okhala ndi kutentha kofananira ndi kuwonongeka.
• Zirconium Phosphate (ZrP):Amapanga chotchinga chosanjikiza pakuwola kwa matenthedwe, koma angafunike nano-sizing kuti achepetse kutentha.

Malangizo Oyesera

1. Thermogravimetric Analysis (TGA):Dziwani kutentha kwa kuwonongeka ndi katundu wa gasi.
2. Kuyesa kwa Electrochemical:Unikani momwe ma ionic conductivity amakhudzira, interfacial impedance, ndi kuyendetsa njinga.
3. Kuyesa kwa Flame Retardancy:mwachitsanzo, kuyesa kuwotcha koyima, kuyeza kwa kuchepa kwa kutentha (pa 140°C).

Mapeto

Thekusinthidwa kwa phosphorous-nitrogen synergistic flame retardant (mwachitsanzo, yokutidwa APP + melamine)amalimbikitsidwa poyamba chifukwa cha kuchedwa kwake kwa lawi komanso kutentha kwake komwe kumawola. Ngati NH₃ iyenera kupewedwa,azo compound systemskapenama microencapsulated CO₂-release systemsndi njira zina zotheka. Kutsimikizika kwapang'onopang'ono koyeserera kumalangizidwa kuti zitsimikizire kukhazikika kwa electrochemical ndi kuthekera kwa njira.
