IiNkqubo zokuVelisa zichaphazela njani ukusebenza kweSilicon yeNano-Hollow
Nano-hollow silicon ibe yenye yezona zinto zithethwa kakhulu malunga nokugcinwa kwamandla aphezulu kunye nezixhobo zokusebenza. Ubume bayo obungenanto bunceda ukujongana nemiceli mngeni emininzi ejongene nesilicon, ngakumbi xa kuziwa ekwandiseni umthamo kunye nokuqina. Kodwa into ehlala ingahoywa yile: ayizizo zonke ii-silicon ezi-nano-hollow ezenza okufanayo. Uninzi lwalo mahluko luvela kwindlela owenziwe ngayo.
Iinkqubo zokuvelisa zidlala indima enkulu kunokuba abantu abaninzi becinga.
Ulwakhiwo luqala kwinqanaba lenkqubo
Kwi-nanoscale, kwanotshintsho lweminithi kwinkqubo yokuvelisa lunokubangela ukungafani okukhulu ekusebenzeni. Ubukhulu beqokobhe lesilicon, ukufana kombindi ongenanto, kunye nokuhanjiswa kobungakanani bamasuntswana zonke zichatshazelwa ngokuthe ngqo yindlela yokudibanisa.
Ukuba iqokobhe lincinci kakhulu, iipellets zinokuwa okanye ziqhekeke phantsi koxinzelelo. Ukuba igobolondo likhulu kakhulu, iingenelo zesakhiwo esingenanto-ezifana nokuguquguquka kunye nokuxinzelela uxinzelelo-ziyancipha. Inkqubo yokuvelisa elawulwa ngononophelo ifezekisa ibhalansi efanelekileyo, ivelisa iipellets ezomelele kwaye ziguquguquke ngokwaneleyo ukuze zisetyenziswe ngokuphindaphindiweyo.
Ukunyamezela kubaluleke ngaphezu kokuzibaxa izinto.
Ukusebenza okuphezulu ephepheni akusoloko kuguqulela kwiziphumo zangempela. Ingxaki eqhelekileyo ngolawulo olubi lwemveliso kukungahambelani komgangatho wemveliso. Xa ubungakanani be-particle kunye nesakhiwo sihluka kakhulu phakathi kweebhetshi ezahlukeneyo, ukusebenza kwemveliso kuba yinto engalindelekanga.
Iimeko zokuvelisa ezizinzileyo zinceda ukuqinisekisa ukusebenza okuhambelanayo kwi-particle nganye. Oku kuhambelana kukhokelela kuqhagamshelwano oluthembekileyo ngakumbi lombane, iimpendulo ezigudileyo, kunye namanqaku ambalwa abuthathaka, ngaloo ndlela kwandiswa ubomi bezinto eziphathekayo. Kwizicelo ezifana neebhetri ze-lithium-ion, ukungaguquguquki kudla ngokubaluleke kakhulu njengokusebenza okuphezulu.
Indima yokwenziwa kwezinto ezihlanganisiweyo
Unyulu nano-hollow silicon sele ibonise inzuzo ebalulekileyo, kodwa ukusebenza kwayo kunokuphuculwa ngakumbi ngokucutshungulwa kwe-composite-ingakumbi i-silicon-carbon composites. Indlela i-silicon kunye nekhabhoni edityaniswe ngayo ichaphazela ngokuthe ngqo i-conductivity, ulawulo lokwandisa, kunye nokuqina okupheleleyo.
Iimbumba ze-silicon-carbon eziyilwe ngononophelo zinokuphucula ukuhanjiswa kwentlawulo, ukunciphisa uxinzelelo ngexesha lokuhamba ngebhayisikile, kwaye zikhusele izakhiwo ze-silicon ekuwohlokeni. Nangona kunjalo, oku kunokwenzeka kuphela ukuba inkqubo yokuvelisa ivumela ukugquma okufanayo, ukudibanisa okuqinileyo, kunye ne-porosity elawulwayo.
Ukulawula ukwandiswa kunye nokuzinza kwexesha elide
Enye yeenzuzo ezinkulu ze-nano-hollow silicon luxinzelelo lwayo olusezantsi lokwandiswa xa kuthelekiswa nesilicon eyomeleleyo. Nangona kunjalo, le nzuzo iyanyamalala ukuba inkqubo yokuvelisa ayilungiswanga. Ulwakhiwo olungenamngxunya olungasebenzi kakuhle lusenokubonisa ukwanda okungalinganiyo, ekugqibeleni lukhokelele ekuqhekekeni okanye ekulahlekeni kwezinto ngokuhamba kwexesha.
Ubuchwephesha obuphezulu bokusebenza bunceda ukugcina ingqibelelo yesakhiwo ngexesha lemijikelezo ephindaphindiweyo, ngaloo ndlela kuncitshiswa i-coefficient yokwandisa kunye nokwandisa ubomi bomjikelezo-zombini izinto ezibalulekileyo kurhwebo.
Ukusebenza kwakhiwe, kungekhona nje ukuyilwa
Abantu bagxila ngokulula kwingcamango yoyilo lwezinto, kodwa ukusebenza ekugqibeleni kuxhomekeke kumgca wemveliso. Kuyafana nano-hollow silicon Uyilo lunokuvelisa iziphumo ezahlukeneyo kakhulu ngokuxhomekeke ekuchanekeni kokwenziwa, ukudibanisa, kunye nobuchule bokuqhuba.
Imveliso ephezulu, ubomi bomjikelezo omude, kunye neendleko-zokusebenza azikho ngengozi-ziyisiphumo seenkqubo ezilawulwayo kunye nezigqibo zobunjineli obusebenzayo.
Iindlela ezisebenzayo zokusebenzisa imathiriyeli ye-silicon ene-nano-hollow
Igesi yeHuazhong isebenzisa i-silicon-hollow ye-silicon njengeyona nto ingundoqo kwaye isebenzisa inkqubo ehlanganisiweyo ye-silicon-carbon ukuvelisa. nano-silicon powder. Le ndlela idibanisa iingenelo ezifana izinga eliphezulu lokukwazi, ukwanda okuphantsi, ubomi bomjikelezo omde, kwaye ukusebenza kweendleko eziphezulu, iyenza ifaneleke kungekuphela nje kwindawo ezingqongileyo zaselabhorethri kodwa kunye nokubanga izicelo zelizwe lokwenyani.
Irhasi yeHuazhong igxile kuyilo lwezixhobo kunye nomgangatho wokuvelisa, ukuxhasa abathengi abafuna ukuthembeka, ukuhla, kunye ixesha elide izixazululo ze-nano-silicon eziphezulu zokusebenza.
