Ukucaciswa Komkhiqizo

IsiceloofI-silicon (Si) nanoparticles:

Izimoto zamandla amasha, ezokuxhumana kanye namadivayisi aphathwayo adinga amabhethri e-lithium-ion ukuze abe nomthamo omkhulu nokukhuthazela okuphezulu.Amabhethri e-lithium-ion adinga ukubuyekezwa ngokushesha ukuze kwandiswe umthamo, umjikelezo nosayizi.Njengamanje, i-silicon-carbon negative electrode yebhethri ye-lithium iyizo zonke izinhlobo zezinto zekhabhoni ezakhiwe ikakhulukazi i-graphite, futhi umthamo wayo wethiyori ungama-372 mAh/g kuphela.Ekusetshenzisweni okusebenzayo, kuseduze nomthamo wethiyori, futhi umthamo we-theoretical we-nano-silica powder uphakeme kakhulu kune-graphite-based carbon material.Ingafinyelela ku-4200mAh/g futhi inezinsizakusebenza eziningi uma kuqhathaniswa.Kuyisinqumo esiyinhloko sezinto ezintsha ze-silicon carbon anode.

IsitorejiofI-silicon (Si) nanoparticles:

I-silicon (Si) nanoparticleskufanele ivalwe futhi igcinwe endaweni eyomile, epholile, kude nelanga eliqondile.

lAmanani Anengqondo

lIzinto ze-nano zekhwalithi ephezulu nezinzile

lIphakheji Lomthengi Linikelwe-Izinsizakalo zokupakisha ngokwezifiso ze-oda lenqwaba

lIsevisi Yokuklama Ihlinzekwa-Nikeza ngesevisi ye-nanopowder yangokwezifiso ngaphambi kwe-oda lenqwaba

lUkuthunyelwa okusheshayo ngemva kokukhokha i-oda elincane

Ilabhorethri

Ithimba labacwaningi lihlanganisa abacwaningi be-Ph. D. kanye noSolwazi, abakwazi ukunakekela kahle

we nano powder's ikhwalithi kanye nokusabela okusheshayo kuma-powder ngokwezifiso.

Izisetshenziswaukuhlola nokukhiqiza.

Inqolobane

Izifunda ezihlukene zokugcina ama-nanopowder ngokuya ngezakhiwo zawo.

Umbuzo: Ngingakwazi ukuthola amasampula?

A: Kuncike kusampula ye-nanopowder oyifunayo.Uma isampula likusitoko ngephakeji elincane, ungathola isampula yamahhala ngokukhava nje izindleko zokuthumela, ngaphandle kwama-nanopowder ayigugu, uzodinga ukukhokhela izindleko zesampula nezindleko zokuthumela.

Q: Ngingasithola kanjani isicelo?A:Sizokunikeza isilinganiso sethu sokuncintisana ngemuva kokuthola imininingwane ye-nanopowder njengosayizi wezinhlayiyana, ubumsulwa;imininingwane yokuhlakazeka njengesilinganiso, isixazululo, usayizi wezinhlayiyana, ubumsulwa.

Q: Ungakwazi yini ukusiza nge-nanopowder eyenziwe ngomthungo?A:Yebo, singakusiza nge-nanopowder eyenziwe ngomsiki, kodwa sizodinga inani elincane le-oda kanye nesikhathi esiholayo cishe amaviki angu-1-2.

Q: Ungaqinisekisa kanjani ikhwalithi yakho?A:Sinohlelo lokulawula ikhwalithi ye-strick kanye nethimba labacwaningi elizinikele, besigxile kuma-nanopowder kusukela ngo-2002, sazuza udumo ngekhwalithi enhle, siyaqiniseka ukuthi ama-nanopowder ethu azokunikeza umkhawulo ngaphezu kwezimbangi zakho zebhizinisi!

Umbuzo: Ngingakwazi ukuthola ulwazi lwedokhumenti?A: Yebo, i-COA, i-SEM, i-TEM iyatholakala.

Q:Ngingalikhokhela kanjani i-oda lami?A: Sincoma i-Ali trade Assurance, nathi imali yakho ivikele ibhizinisi lakho endaweni ephephile.

Ezinye izindlela zokukhokha esizamukelayo: PayPal, Western Union, Ebhange, L/C.

Q: Kuthiwani ngesikhathi esisheshayo nesokuthumela?A:Isevisi ye-Courier njenge: DHL, Fedex, TNT, EMS.
