Ongorora: zvinoenderana nemushandisi zvinodiwa zve nano particle inogona kupa akasiyana saizi zvigadzirwa.

Kuita kwechigadzirwa

Iyo yakasarudzika magadzirirwo ecarbon nanotubes inotaridza kuti ane akawanda akakosha emuviri nemakemikari zvinhu.Iyo C=C covalent bond yekabhoni nanotubes ndiyo yakagadzikana kwazvo chemikemikari bond muzvisikwa, saka kabhoni nanotubes ine yakanakisa mechanical properties.Theoretical calculations inoratidza kuti carbon nanotubes simba guru uye kuoma.

Maitiro ekushandisa

Kushandiswa kwekabhoni nanotubes mune cathode zvinhu zve lithium ion mabhatiri:

1. Carbon nanotubes - silicon matrix composites

Silicon, seye cathode zvinhu zve lithium bhatiri, ine yakakwira kwazvo theoretical chaiyo kugona (4200 mAh/g).Panguva imwecheteyo, silicon zvinhu ine yakaderera discharge kugona, iyo inobatsira kubuda kweyepamusoro voltage yelithium ion bhatiri, uye silicon yakawanda.Nekudaro, mukuita kwekuchaja nekuburitsa, huwandu hwesilicon hunochinja zvakanyanya (anenge 400%), izvo zvinoita kuti iyo silicon zvinhu ikurumidze kuita hupfu uye kukundikana mushure mekufamba kwakati wandei, zvichikonzera kugadzikana kwebhasikoro uye nekukurumidza shanduko.Uye silicon haina kuita zvakanaka.Iko kuunzwa kwekabhoni nanotubes haingovharidzi shanduko yevhoriyamu yesilicon panguva yekuchaja uye yekuburitsa.Panguva imwecheteyo, iyo yakanakisa yemagetsi conductivity yekabhoni nanotubes inobatsirawo kuvandudza kutakura uye kupararira mwero welithium ions muzvinyorwa, nekudaro kuvandudza kuita kwe lithium kuchengetedza kweiyo composite zvinhu.

2.Carbon nanotubes - metal oxide composites

Zvakafanana nesilicon zvinhu, simbi oxides zvakare ine dambudziko rekushomeka conductivity uye yakakura vhoriyamu shanduko panguva yekuchaja nekuburitsa.Carbon nanotubes inogona kusanganiswa nesimbi oxides pane nanoscale, kuitira kuti ikunde kushata kwehurombo conductivity yesimbi oxides uye kuderedza polarization phenomenon mukuchaja nekuburitsa.Pamusoro pezvo, kabhoni nanotubes inopawo mechanical framework yesimbi oxide particles kudzivirira kuderedzwa kwehuwandu nekuda kwekuputika kwavo.

Kuchengetedza mamiriro

Ichi chigadzirwa chinofanira kuchengetwa munzvimbo yakaoma, inotonhorera uye chisimbiso chezvakatipoteredza, haigone kuratidzwa nemhepo, uyezve inofanirwa kudzivirira inorema, zvinoenderana neyakajairwa kutakura zvinhu.

Mubvunzo: Unogona kundigadzirira quote / proforma invoice?A: Hongu, boka redu rekutengesa rinogona kupa zvinyorwa zvepamutemo kwauri.Zvisinei, unofanira kutanga wataura kero yekubhadhara, kero yekutumira, kero ye-e-mail, nhamba yefoni uye nzira yekutumira.Hatigone kugadzira quote chaiyo pasina ruzivo urwu.

Mubvunzo: Unotumira sei odha yangu?Unogona kutumira "kutakura zvinhu"?A: Tinogona kutumira odha yako kuburikidza neFedex, TNT, DHL, kana EMS kuaccount yako kana prepayment.Isu tinotumirawo "kutakura zvinhu" kuaccount yako.Iwe uchagamuchira zvinhu muInotevera 2-5 Mazuva mushure mekutumira, Nokuda kwezvinhu zvisiri muzvitoro, purogiramu yekutumira ichasiyana zvichienderana nechinhu chacho.Ndapota taura neboka redu rekutengesa kuti ubvunze kana zvinhu zviri muzvitoro.

Mubvunzo: Unobvuma maodha ekutenga here?A: Tinobvuma kutenga maodha kubva kune vatengi vane nhoroondo yechikwereti nesu, unogona fax, kana email yekutenga odha kwatiri.Ndokumbirawo muve nechokwadi chekuti odha yekutenga ine zvese zvekambani / masangano tsamba uye siginecha yakatenderwa pairi.Zvakare, iwe unofanirwa kutsanangura munhu wekusangana naye, kero yekutumira, email kero, nhamba yefoni, nzira yekutumira.

Mubvunzo: Ndingabhadhara sei kurongeka kwangu?Mubvunzo: Nezve mubhadharo, tinobvuma kutumira telegraphic, kumadokero mubatanidzwa uye PayPal.L/C ndeyepamusoro pe50000USD dhiri chete. Kana nechibvumirano chebvumirano, mativi ese ari maviri anogona kugamuchira mari yekubhadhara.Hazvinei kuti ndeipi nzira yekubhadhara yawakasarudza, ndapota titumire waya yekubhangi nefax kana email mushure mekunge wapedza kubhadhara kwako.

Mubvunzo: Pane mamwe mari here?A: Kupfuura mutengo wezvigadzirwa uye mutengo wekutumira, isu hatibhadharise chero mari.

Mubvunzo: Unogona kundigadzirira chigadzirwa here?A: Hongu.Kana paine nanoparticle yatisina mustock, saka hongu, zvinowanzoitika kuti isu tikugadzirire iwe.Nekudaro, kazhinji inoda hushoma hwehuwandu hwakaodha, uye anenge 1-2 mavhiki ekutungamirira nguva.

Q. Zvimwe.A: Zvinoenderana nechero maodha, isu tichakurukura nemutengi nezve nzira yekubhadhara yakakodzera, kushandira pamwe kuti tipedze zvirinani zvekufambisa uye zvine chekuita nekutengeserana.
