Kuongorora Kunodzora Murazvo uye Mazano eBattery Separator Coatings

Kuongorora Kunodzora Murazvo uye Mazano eBattery Separator Coatings

Mutengi anogadzira ma "separator" emabhatiri, uye pamusoro pe "separator" panogona kuputirwa ne "layer", inowanzo kuve "alumina" (Al₂O₃) ne "binder" shoma. Iye zvino vari kutsvaga zvimwe zvinodzora moto kuti zvitsive "alumina", nezvinodiwa zvinotevera:

• Kunonoka kwemurazvo kunoshanda pa140°C(semuenzaniso, kuora kuti kuburitse magasi asina simba).
• Kugadzikana kwemakemikari emagetsiuye kuenderana nezvikamu zvebhatiri.

Zvinokurudzirwa Zvinodzivirira Moto uye Kuongorora

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

Maitiro:

• Chitubu cheasidhi (APP) nechitubu chegasi (melamine) zvinobatana kuti zviburitse NH₃ neN₂, zvichideredza okisijeni uye zvichigadzira jira rechar kudzivirira moto.
  Zvakanakira:
• Kubatana kwephosphorus-nitrogen kunogona kuderedza tembiricha yekuora (inogona kugadziriswa kusvika ~140°C kuburikidza ne nano-size kana formula).
• N₂ igesi isina simba; NH₃ kukanganisa pa electrolyte (LiPF₆) kunoda kuongororwa.
  Zvaunofanira Kufunga nezvazvo:
• Tarisa kugadzikana kweAPP muma electrolytes (dzivisa hydrolysis kuita phosphoric acid neNH₃). Silica coating inogona kuwedzera kugadzikana.
• Kuongororwa kwekuenderana kwemagetsi (semuenzaniso, cyclic voltammetry) kunodiwa.

2. Zvinodzivirira Moto Zvinobva kuNitrogen (semuenzaniso, Masisitimu eAzo Compound)

Munyoreri:Azodicarbonamide (ADCA) ine activators (semuenzaniso, ZnO).
Maitiro:

• Tembiricha yekuora inogadziriswa kusvika 140–150°C, ichiburitsa N₂ neCO₂.
  Zvakanakira:
• N₂ igesi isina simba yakakwana, isingakuvadzi mabhatiri.
  Zvaunofanira Kufunga nezvazvo:
• Kudzora zvigadzirwa (semuenzaniso, CO, NH₃).
• Microencapsulation inogona kunyatsogadzirisa tembiricha yekuora.

3. Masisitimu eCarbonate/Acid Thermal Reaction (semuenzaniso, Microencapsulated NaHCO₃ + Acid Source)

Maitiro:

• Microcapsules dzinoputika pa140°C, zvichikonzera kusangana pakati peNaHCO₃ ne organic acid (semuenzaniso, citric acid) kuti CO₂ iburitswe.
  Zvakanakira:
• CO₂ haina simba uye yakachengeteka; tembiricha yekupindura inodzorwa.
  Zvaunofanira Kufunga nezvazvo:
• Maion eSodium anogona kukanganisa kutakurwa kweLi⁺; funga nezve lithium salts (semuenzaniso, LiHCO₃) kana kudzivirira kufamba kweNa⁺ mu coating.
• Gadzirisa kuvharwa kwemukati kuti kugadzikane nekupisa kwemukamuri.

Dzimwe Sarudzo Dzinogona Kuitwa

• Mafuremu esimbi-ezvinhu zvakasikwa (MOFs):Semuenzaniso, ZIF-8 inoora kana tembiricha yakakwira kuti ibudise gasi; inovhara MOF dzine tembiricha dzakafanana dzekuora.
• Zirconium Phosphate (ZrP):Inoita chigadziko chinodzivisa kupisa kana yaora, asi ingada saizi shoma kuti ideredze kupisa kana yaora.

Mazano Ekuyedza

1. Kuongorora Thermogravimetric (TGA):Sarudza tembiricha yekuora uye hunhu hwekuburitsa gasi.
2. Kuedzwa kweElectrochemical:Ongorora simba reionic conductivity, interfacial impedance, uye mashandiro ecycling.
3. Kuedzwa kweKudzoreredza Murazvo:semuenzaniso, bvunzo yekupisa yakamira, kuyerwa kwekupwanyika kwekupisa (pa 140°C).

Mhedziso

Iyophosphorus-nitrogen synergistic fire retardant yakagadziriswa (semuenzaniso, APP yakaputirwa + melamine)Inokurudzirwa kutanga nekuda kwekusadzora moto kwakaringana uye tembiricha yekuora inogadziriswa. Kana NH₃ ichifanira kudzivirirwa,masisitimu emakemikari eazokanamasisitimu ekuburitsa CO₂ akavharirwa muzvikamu zvidikidzimwe nzira dzinoshanda. Kuongororwa kwekuyedza kunokurudzirwa kuti kuve nechokwadi chekuti electrochemical yakagadzikana uye kuti maitiro acho anogona kushanda.
