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 nge-Fedex, TNT, DHL, okanye i-EMS kwiakhawunti yakho okanye ukuhlawula kwangaphambili.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 inazo zombini iiletahedi yenkampani/iziko 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. | ||||||||||||||||||||
