Qaphela: ngokwezidingo zomsebenzisi ze-nano particle ingahlinzeka ngemikhiqizo yosayizi ehlukene.

Ukusebenza komkhiqizo

Isakhiwo esiyingqayizivele sama-carbon nanotubes sinquma ukuthi anezinto eziningi ezikhethekile zomzimba namakhemikhali.I-C=C covalent bond ye-carbon nanotubes iyisibopho samakhemikhali esizinzile kakhulu emvelweni, ngakho-ke ama-carbon nanotubes anezakhiwo ezinhle kakhulu zemishini.Izibalo zethiyori zibonisa ukuthi ama-carbon nanotubes anawo. amandla amakhulu kanye nokuqina.

Isiqondiso sohlelo lokusebenza

Ukusetshenziswa kwe-carbon nanotubes ezintweni ze-cathode zamabhethri e-lithium ion:

1. Ama-nanotubes e-carbon - izinhlanganisela ze-silicon matrix

I-silicon, njenge-cathode material yebhethri ye-lithium, inomthamo othize ophakeme kakhulu (4200 mAh/g).Ngesikhathi esifanayo, izinto ze-silicon zinamandla aphansi okukhipha, okuhambisana nokukhishwa kwamandla aphezulu webhethri ye-lithium ion, futhi i-silicon iyiningi.Kodwa-ke, ngesikhathi sokushaja nokukhipha, umthamo we-silicon ushintsha kakhulu (cishe u-400%), okwenza izinto ze-silicon zibe yimpuphu ngokushesha futhi zihluleke ngemva kwemijikelezo eminingana, okuholela ekuzinzeni kwebhayisikili kanye noshintsho olusheshayo.Futhi i-silicon ayisebenzi kahle.Ukwethulwa kwe-carbon nanotubes akukwazi nje ukuvimbela ukushintsha kwevolumu ye-silicon ngesikhathi sokushaja nokukhipha inqubo.Ngasikhathi sinye, i-conductivity kagesi enhle kakhulu ye-carbon nanotubes iphinde isize ekuthuthukiseni izinga lokuthutha kanye nokusabalalisa kwe-lithium ion ku-material, ngaleyo ndlela kuthuthukiswe ukusebenza kwe-lithium yokugcina impahla eyinhlanganisela.

2.Ama-nanotubes e-Carbon - izinhlanganisela ze-metal oxide

Ngokufana nezinto ze-silicon, ama-oxide ensimbi nawo anenkinga ye-conductivity ephansi kanye nokushintsha kwevolumu enkulu ngesikhathi sokushaja nokukhipha.Ama-nanotubes e-carbon angahlanganiswa nama-oxide ensimbi ku-nanoscale, ukuze anqobe ubungozi bokungahambi kahle kahle kwama-oxide ensimbi futhi anciphise i-polarization enqubweni yokushaja nokukhipha.Ngaphezu kwalokho, i-carbon nanotubes iphinde inikeze uhlaka lwemishini lwezinhlayiya ze-metal oxide ukugwema ukuwohloka komthamo ngenxa ye-pulverization yazo.

Izimo zokugcina

Lo mkhiqizo kufanele ugcinwe endaweni eyomile, epholile futhi evala imvelo, awukwazi ukuchayeka emoyeni, ngaphezu kwalokho kufanele ugweme ukucindezela okunzima, ngokusho kokuthutha kwezimpahla ezijwayelekile.

Q: Ungakwazi ukungenzela i-quote/invoyisi ye-proforma?IMP: Yebo, ithimba lethu labadayisi lingakunikeza izingcaphuno ezisemthethweni. Nokho, kufanele uqale ucacise ikheli lokukhokha, ikheli lokuthumela, ikheli le-imeyili, inombolo yocingo kanye nendlela yokuthumela.Asikwazi ukudala isisho esinembile ngaphandle kwalolu lwazi.

Umbuzo: Ulithumela kanjani i-oda lami?Ungakwazi yini ukuthumela “impahla yokuqoqa”?A: Singakuthumela i-oda lakho nge-Fedex, TNT, DHL, noma i-EMS ku-akhawunti yakho noma ngokukhokha kusengaphambili.Siphinde sithumele "iqoqo lezimpahla" nge-akhawunti yakho.Uzothola izimpahla Ezinsukwini Ezilandelayo Ezingu-2-5 ngemva kokuthunyelwa, Ezintweni ezingekho esitokweni, ishejuli yokulethwa izohluka ngokusekelwe entweni.Sicela uxhumane nethimba lethu labadayisi ukuze ubuze ukuthi ingabe into ethile ikhona yini esitokweni.

Umbuzo: Uyawamukela ama-oda okuthenga?IMP: Samukela ama-oda okuthenga avela kumakhasimende anomlando wesikweletu kithi, ungasifeksela, noma usithumelele i-oda lokuthenga nge-imeyili.Sicela uqiniseke ukuthi i-oda lokuthenga linakho kokubili isihloko sencwadi yenkampani/isikhungo nesiginesha egunyaziwe kuyo.Futhi, kufanele ucacise umuntu oxhumana naye, ikheli lokuthumela, ikheli le-imeyili, inombolo yocingo, indlela yokuthumela.

Umbuzo: Ngingalikhokhela kanjani i-oda lami?Q: Mayelana nenkokhelo, siyakwamukela ukudluliswa kwezingcingo, inyunyana yasentshonalanga kanye ne-PayPal.I-L/C eyedili elingaphezu kuka-50000USD kuphela. Noma ngesivumelwano sobabili, izinhlangothi zombili zingamukela imigomo yokukhokha.Kungakhathaliseki ukuthi iyiphi indlela yokukhokha oyikhethile, sicela usithumelele ucingo lwasebhange ngefeksi noma i-imeyili ngemva kokuqeda ukukhokha kwakho.

Umbuzo: Ingabe zikhona ezinye izindleko?A: Ngaphandle kwezindleko zomkhiqizo nezindleko zokuthumela, asikhokhisi noma yiziphi izimali.

Umbuzo: Ungakwazi ukungenzela umkhiqizo ngokwezifiso?A: Yebo.Uma kukhona i-nanoparticle esingenayo esitokweni, ngakho-ke yebo, ngokuvamile kungenzeka ukuthi sikukhiqizele yona.Kodwa-ke, imvamisa idinga inani elincane lenani eli-odwe, futhi cishe amaviki angu-1-2 wokuhola.

Q. Okunye.IMP: Ngokwawo wonke ama-oda athile, sizoxoxa nekhasimende mayelana nendlela yokukhokha efanelekile, sibambisane ukuze siqedele kangcono ezokuthutha kanye nemisebenzi ehlobene.
