Intshayelelo:
Iibhetri zeLithiumluhlobo lwebhetri olusebenzisa i-lithium metal okanye i-lithium alloy njengezinto ze-electrode ezingezizo ezamanzi kwaye lusebenzisa isisombululo se-electrolyte esingengomanzi. Ngenxa yeempawu zekhemikhali ezisebenzayo kakhulu ze-lithium metal, ukucubungula, ukugcina, kunye nokusetyenziswa kwe-lithium metal kuneemfuno eziphezulu kakhulu zokusingqongileyo. Okulandelayo, makhe sijonge iinkqubo ze-homogenization, coating, kunye ne-rolling ekulungiseleleni iibhetri ze-lithium.
Ukuhlanganiswa kwe-electrode okuhle nokubi
I-electrode yebhetri ye-lithium-ion yeyona nto ibalulekileyo kwiseli yebhetri. I-homogenization ye-electrode elungileyo nengalunganga ibhekisa kwinkqubo yokulungiselela i-slurry egqunywe kumaphepha e-electrode elungileyo nengalunganga e-lithium ion. Ukulungiswa kwe-slurry kufuna ukuxuba izinto ze-electrode ezilungileyo, izinto ze-electrode ezimbi, i-ejenti yokuqhuba kunye ne-binder. I-slurry elungisiweyo kufuneka ifane kwaye izinzile.
Abavelisi beebhetri ze-lithium ezahlukeneyo baneendlela zabo zenkqubo ye-homogenization. Ulandelelwano lokongeza izinto, umlinganiselo wokongeza izinto kunye nenkqubo yokuxuba kwinkqubo ye-homogenization zinempembelelo enkulu kwisiphumo se-homogenization. Emva kwe-homogenization, i-slurry kufuneka ivavanywe umxholo oqinileyo, i-viscosity, ubunono, njl.njl. ukuqinisekisa ukuba ukusebenza kwe-slurry kuyahlangabezana neemfuno.
Ukwaleka
Inkqubo yokugquma yinkqubo esekelwe kuphononongo lweempawu zolwelo, apho umaleko omnye okanye ngaphezulu wolwelo ugqunywa kwi-substrate. I-substrate idla ngokuba yifilimu eguquguqukayo okanye iphepha elingasemva, kwaye emva koko ulwelo olugqunywe luyomiswa kwi-oven okanye lucocwe ukuze lwenze umaleko wefilimu onemisebenzi ekhethekileyo.
Ukugquma yinkqubo ebalulekileyo ekulungiseleleni iiseli zebhetri. Umgangatho wokugquma unxulumene ngqo nomgangatho webhetri. Kwangaxeshanye, iibhetri ze-lithium-ion zinobuthathaka kakhulu kumswakama ngenxa yeempawu zenkqubo. Ubungakanani obuncinci bomswakama bunokuba nefuthe elibi ekusebenzeni kombane kwebhetri; inqanaba lokusebenza kokugquma linxulumene ngqo nezalathisi ezisebenzayo ezifana neendleko kunye nexabiso elifanelekileyo.
Inkqubo yokuvelisa uboya
I-substrate egqunyiweyo iyasuswa kwisixhobo sokukhulula ize ifakwe kumatshini wokugquma. Emva kokuba intloko nomsila we-substrate ziqhagamshelwe ukwenza ibhanti eqhubekayo kwitafile yokuqhawula, zifakwa kwisixhobo sokulungisa uxinzelelo kunye nesixhobo sokulungisa ukuphambuka ngokuzenzekelayo sisixhobo sokutsala, kwaye zingene kwisixhobo sokugquma emva kokulungisa ukuxinana kwendlela yeshiti kunye nendawo yendlela yeshiti. I-slurry yesiqwenga sepali igqunywe ngamacandelo kwisixhobo sokugquma ngokwenani lokugquma elimiselweyo kunye nobude obungenanto.
Xa kugqunywa icala elimacala mabini, ugqunywa olungaphambili kunye nobude obungenanto zilandelelwa ngokuzenzekelayo ukuze kugqunywe. I-electrode emanzi emva kogqunywa ithunyelwa kumjelo wokomisa ukuze yome. Ubushushu bokomisa bumiselwa ngokwesantya sogqunywa kunye nobukhulu bogqunywa. I-electrode eyomileyo igoqwa emva kokulungiswa koxinzelelo kunye nokulungiswa kokuphambuka ngokuzenzekelayo kwinqanaba elilandelayo lokucubungula.
Ukuqengqeleka
Inkqubo yokuqengqeleka kweziqwenga zepali zebhetri ye-lithium yinkqubo yemveliso ecinezela ngokufanayo izinto eziluhlaza ezifana nezinto ezisebenzayo, ii-conductive agents kunye nee-binders kwi-foil yesinyithi. Ngenkqubo yokuqengqeleka, isiqwenga sepali sinokuba nendawo esebenzayo ye-electrochemical ephezulu, ngaloo ndlela siphucula uxinano lwamandla kunye nokusebenza kwebhetri yokutshaja kunye nokukhupha. Kwangaxeshanye, inkqubo yokuqengqeleka inokwenza isiqwenga sepali sibe namandla aphezulu olwakhiwo kunye nokuhambelana okuhle, okunceda ukuphucula ubomi bomjikelo kunye nokhuseleko lwebhetri.
Inkqubo yemveliso yokuqengqeleka
Inkqubo yokuqengqeleka kweziqwenga zepali zebhetri ye-lithium ibandakanya ikakhulu ukulungiswa kwezinto eziluhlaza, ukuxuba, ukuxinana, ukubumba kunye nezinye iikhonkco.
Ukulungiswa kwezinto eziluhlaza kukuxuba izinto ezahlukeneyo ngokulinganayo kunye nokongeza isixa esifanelekileyo sesinyibilikisi ukuze kuxutywe ukuze kufunyanwe uthuli oluzinzileyo.
Ikhonkco lokuxuba lelokuxuba izinto ezahlukeneyo ngokulinganayo ukuze kuqiniswe kwaye kulungiswe izinto ezisetyenzisiweyo.
Ikhonkco lokuxinana kukucinezela udaka nge-roller press ukuze amasuntswana ezinto ezisebenzayo abekwe ngokusondeleyo ukuze enze i-pole piece enamandla athile olwakhiwo. Ikhonkco lokubumba likukunyanga i-pole piece ngobushushu obuphezulu kunye noxinzelelo oluphezulu ngezixhobo ezifana ne-hot press ukulungisa imo kunye nobukhulu be-pole piece.
