Qaphela: ngokweemfuno zomsebenzisi we-nano particle inokubonelela ngeemveliso zobukhulu obuhlukeneyo.

Ukusebenza kwemveliso

Isakhiwo esikhethekileyo se-carbon nanotubes sinquma ukuba zineempawu ezininzi ezikhethekileyo zomzimba kunye neekhemikhali.I-C = C ibhondi ye-covalent ye-carbon nanotubes yeyona bhondi yeekhemikhali ezizinzile kwindalo, ngoko ke i-carbon nanotubes ineempawu ezibalaseleyo zomatshini.Izibalo zethiyori zibonisa ukuba i-carbon nanotubes amandla amakhulu kunye nokuqina.

Ulwalathiso lwesicelo

Ukusetyenziswa kwe-carbon nanotubes kwizinto ze-cathode kwiibhetri ze-lithium ion:

1. I-carbon nanotubes - i-silicon matrix composites

I-silicon, njengesixhobo se-cathode yebhetri ye-lithium, inomthamo ophezulu kakhulu wethiyori (4200 mAh / g). Kwangaxeshanye, izinto ze-silicon zinamandla aphantsi okukhutshwa, okulungele ukukhutshwa kwamandla aphezulu ebhetri ye-lithium ion, kwaye i-silicon ininzi. Nangona kunjalo, kwinkqubo yokutshaja kunye nokukhupha, umthamo we-silicon uguquka kakhulu (malunga ne-400%), okwenza izinto ze-silicon zibe ngumgubo ngokukhawuleza kwaye zisilele emva kwemijikelezo emininzi, okubangelwa ukuzinza kwebhayisikili kunye nokutshintsha ngokukhawuleza. Kwaye i-silicon ayiqhubeki kakuhle. Ukuqaliswa kwe-carbon nanotubes akunakunqanda kuphela ukuguqulwa kwevolumu ye-silicon ngexesha lokutshaja kunye nokukhupha inkqubo. Ngelo xesha, i-conductivity yombane egqwesileyo ye-carbon nanotubes iphinda incede ekuphuculeni ukuthuthwa kunye nesantya sokusasazwa kwe-lithium ion kwizinto eziphathekayo, ngaloo ndlela kuphuculwe ukusebenza kokugcinwa kwe-lithium yezinto ezidibeneyo.

2.I-Carbon nanotubes - i-metal oxide composites

Ngokufana nezixhobo ze-silicon, ii-oxide zetsimbi nazo zinengxaki ye-conductivity ephantsi kunye nokutshintsha umthamo omkhulu ngexesha lokutshaja kunye nokukhupha. I-Carbon nanotubes inokudityaniswa kunye nee-oxide zetsimbi kwi-nanoscale, ukuze unqobe ukungabikho kokungahambi kakuhle kwee-oxide zetsimbi kunye nokunciphisa i-polarization phenomenon kwinkqubo yokutshaja kunye nokukhupha. Ukongeza, i-carbon nanotubes ikwabonelela ngesakhelo soomatshini kwi-particle oxide oxide ukuphepha ukuthotywa komthamo ngenxa ye-pulverization yabo.

Iimeko zokugcina

Le mveliso kufuneka igcinwe kwindawo eyomileyo, epholileyo kunye nokutywinwa kokusingqongileyo, ayikwazi ukubonakaliswa emoyeni, ngaphezu koko kufuneka igweme uxinzelelo olunzima, ngokuhambelana nokuthuthwa kwempahla eqhelekileyo.

Umbuzo: Ngaba ungandenzela i-quote/invoyisi yeproforma? A: Ewe, iqela lethu lokuthengisa linokubonelela ngeengcaphuno ezisemthethweni kuwe.Nangona kunjalo, kufuneka uqale ucacise idilesi yokuhlawula, idilesi yokuthumela, idilesi ye-imeyile, inombolo yefowuni kunye nendlela yokuthumela. Asikwazi ukwenza isicatshulwa esichanekileyo ngaphandle kolu lwazi.

Umbuzo: Uyithumela njani iodolo yam? Ngaba ungathumela "impahla yokuqokelela"? A: Singathumela iodolo yakho ngeFedex, TNT, DHL, okanye EMS kwiakhawunti yakho okanye ngentlawulo yangaphambili. Sikwathumela "impahla yokuqokelela" kwiakhawunti yakho. Uya kufumana iimpahla ngeentsuku ezi-2-5 ezizayo emva kokuthunyelwa, Kwizinto ezingekho kwisitokhwe, ishedyuli yokuhanjiswa iya kwahluka ngokusekelwe kwinto.Nceda uqhagamshelane neqela lethu lokuthengisa ukuba ubuze ukuba ingaba impahla ikhona.

Umbuzo: Ngaba uyazamkela iiodolo zokuthenga? A: Siyazamkela iiodolo zokuthenga kubathengi abanembali yetyala kuthi, ungafeksa, okanye uthumele i-imeyile yomyalelo wokuthenga kuthi. Nceda uqinisekise ukuba iodolo yokuthenga ineletahedi yenkampani/yeziko kunye nesiginitsha egunyazisiweyo kuyo. Kwakhona, kufuneka ucacise umntu oqhagamshelana naye, idilesi yokuthumela, idilesi ye-imeyile, inombolo yefowuni, indlela yokuthumela.

Umbuzo: Ndingayihlawula njani iodolo yam? Umbuzo: Malunga nentlawulo, siyalwamkela utshintshiselwano lwetelegraphic, imanyano yasentshona kunye nePayPal. I-L/C ingaphezulu kwe-50000USD kuphela isivumelwano. Nokuba yeyiphi indlela yokuhlawula oyikhethileyo, nceda usithumele ucingo lwebhanki ngefeksi okanye nge-imeyile emva kokuba ugqibile intlawulo yakho.

Umbuzo: Ngaba zikhona ezinye iindleko? A: Ngaphandle kweendleko zemveliso kunye neendleko zokuthumela, asihlawulisi nayiphi na imali.

Umbuzo: Ngaba ungandenzela imveliso ngokwezifiso? A: Ewe kunjalo. Ukuba kukho i-nanoparticle esingenayo kwisitokisini, ngoko ewe, ngokuqhelekileyo kunokwenzeka ukuba siyivelisele yona. Nangona kunjalo, ihlala ifuna ubuncinci bemiyinge eodolweyo, kwaye malunga neeveki ezi-1-2 zokukhokela.

Q. Okunye. A: Ngokwemiyalelo yonke ethile, siya kuxoxa nomthengi malunga nendlela yokuhlawula efanelekileyo, sisebenzisane ukuze sigqibezele ngcono uthutho kunye neentengiselwano ezinxulumeneyo.
