Lus Cim: Raws li cov neeg siv khoom xav tau ntawm nano particle tuaj yeem muab cov khoom sib txawv.

Khoom ua haujlwm

Cov qauv tshwj xeeb ntawm cov pa roj carbon nanotubes txiav txim siab tias lawv muaj ntau yam tshwj xeeb ntawm lub cev thiab tshuaj lom neeg.C = C covalent daim ntawv cog lus ntawm carbon nanotubes yog cov tshuaj ruaj khov tshaj plaws hauv cov xwm txheej, yog li cov pa roj carbon nanotubes muaj cov khoom siv zoo heev. zoo zog thiab toughness.

Daim ntawv thov kev taw qhia

Kev siv cov pa roj carbon nanotubes hauv cov ntaub ntawv cathode rau lithium ion roj teeb:

1. Carbon nanotubes – silicon matrix composites

Silicon, raws li cov khoom siv cathode ntawm lithium roj teeb, muaj lub peev xwm theoretical siab heev (4200 mAh / g).Nyob rau tib lub sijhawm, cov khoom siv silicon muaj qhov tso tawm tsawg, uas yog qhov tsim nyog rau cov khoom siv hluav taws xob ntau dua ntawm lithium ion roj teeb, thiab silicon muaj ntau.Txawm li cas los xij, nyob rau hauv tus txheej txheem ntawm kev them nyiaj thiab kev tso tawm, qhov ntim ntawm silicon hloov pauv ntau heev (li 400%), uas ua rau cov khoom siv silicon sai sai hmoov thiab ua tsis tiav tom qab ob peb lub voj voog, uas ua rau kev caij tsheb kauj vab thiab kev hloov pauv sai.Thiab silicon tsis ua haujlwm zoo.Kev taw qhia ntawm cov pa roj carbon nanotubes tuaj yeem tsis tsuas yog cuam tshuam lub ntim hloov ntawm silicon thaum lub sijhawm them nyiaj thiab tso tawm cov txheej txheem.Nyob rau tib lub sijhawm, cov khoom siv hluav taws xob zoo heev ntawm cov pa roj carbon nanotubes kuj tseem pab txhim kho kev thauj mus los thiab kev sib kis ntawm lithium ions hauv cov khoom, yog li txhim kho lithium cia kev ua tau zoo ntawm cov khoom sib xyaw.

2.Carbon nanotubes - hlau oxide composites

Zoo ib yam li cov ntaub ntawv silicon, cov hlau oxides kuj muaj qhov teeb meem ntawm cov khoom siv hluav taws xob tsawg thiab hloov pauv loj thaum lub sij hawm them thiab tawm.Cov pa roj carbon nanotubes tuaj yeem sib xyaw nrog cov hlau oxides ntawm nanoscale, kom kov yeej qhov tsis zoo ntawm kev ua tsis zoo ntawm cov hlau oxides thiab txo cov polarization tshwm sim hauv cov txheej txheem them thiab tawm.Tsis tas li ntawd, cov pa roj carbon nanotubes tseem muab cov txheej txheem ua haujlwm rau cov hlau oxide kom tsis txhob muaj peev xwm degradation vim lawv cov pulverization.

Cia tej yam kev mob

Cov khoom no yuav tsum tau muab cia rau hauv qhuav, txias thiab sealing ntawm ib puag ncig, tsis tuaj yeem raug rau huab cua, ntxiv rau yuav tsum zam qhov hnyav, raws li kev thauj khoom zoo tib yam.

Q: Koj puas tuaj yeem kos ib daim ntawv them nqi / proforma rau kuv?A: Yog lawm, peb pab neeg muag khoom tuaj yeem muab cov lus tshaj tawm rau koj.Txawm li cas los xij, koj yuav tsum xub qhia qhov chaw nyob them nqi, chaw nyob xa khoom, e-mail chaw nyob, xov tooj thiab txoj kev xa khoom.Peb tsis tuaj yeem tsim cov lus qhia tseeb yog tias tsis muaj cov ntaub ntawv no.

Q: Koj xa kuv li cas?Koj puas tuaj yeem nkoj "freight sau"?A: Peb tuaj yeem xa koj daim ntawv xaj los ntawm Fedex, TNT, DHL, lossis EMS ntawm koj tus as-qhauj lossis them ua ntej.Peb kuj xa "freight collect" tawm tsam koj tus account.Koj yuav tau txais cov khoom tom ntej 2-5 Hnub tom qab xa khoom, Rau cov khoom uas tsis nyob hauv Tshuag, lub sij hawm xa khoom yuav txawv raws li cov khoom.Thov hu rau peb pab neeg muag khoom kom nug seb cov khoom puas nyob hauv Tshuag.

Q: Koj puas kam txais kev txiav txim?A: Peb lees txais kev xaj xaj los ntawm cov neeg siv khoom uas muaj keeb kwm lees paub nrog peb, koj tuaj yeem fax, lossis xa email tuaj rau peb.Thov xyuas kom meej tias daim ntawv xaj yuav muaj ob lub tuam txhab / lub tsev ntawv tsab ntawv thiab daim ntawv tso cai kos npe rau ntawm nws.Tsis tas li ntawd, koj yuav tsum qhia tus neeg tiv tauj, chaw nyob shipping, email chaw nyob, xov tooj, txoj kev xa khoom.

Q: Kuv tuaj yeem them kuv li cas?Q: Txog kev them nyiaj, peb lees txais kev xa xov tooj xa mus, sab hnub poob union thiab PayPal.L / C tsuas yog rau saum toj 50000USD deal.Los yog los ntawm kev pom zoo, ob tog tuaj yeem lees txais cov nqe lus them nqi.Txawm tias koj xaiv txoj kev them nyiaj twg, thov xa peb lub txhab nyiaj xaim los ntawm fax lossis email tom qab koj them nyiaj tiav.

Q: Puas muaj lwm yam nqi?A: Tshaj li cov nqi khoom thiab cov nqi thauj khoom, peb tsis them tus nqi.

Q: Koj puas tuaj yeem kho qhov khoom rau kuv?A: Tau kawg.Yog tias muaj nanoparticle uas peb tsis muaj nyob rau hauv Tshuag, ces yog, nws yog feem ntau ua tau rau peb kom tau nws ua rau koj.Txawm li cas los xij, nws feem ntau yuav tsum muaj qhov tsawg kawg nkaus ntawm cov khoom xaj, thiab txog li 1-2 lub lis piam ua ntej.

Q. Lwm yam.A: Raws li txhua qhov kev txiav txim tshwj xeeb, peb yuav tham nrog cov neeg siv khoom txog txoj kev them nqi tsim nyog, koom tes nrog ib leeg kom ua tiav cov kev thauj mus los thiab lwm yam kev lag luam.
