Ngaphambili, sazisa inkqubo yangaphambili kunye nenqanaba eliphakathi lokwenziwa kwebhetri ye-lithium ngokweenkcukacha. Eli nqaku liza kuqhubeka nokwazisa inkqubo yokuphela komva.
Injongo yemveliso yenkqubo yokubuyela emva kukugqiba ukubunjwa kunye nokupakishwa kwebhetri ye-lithium-ion. Kwinqanaba eliphakathi, isakhiwo esisebenzayo seseli senziwe, kwaye ezi seli kufuneka zisebenze kwinkqubo kamva. Inkqubo ephambili kumanqanaba amva ibandakanya: kwiqokobhe, ukubhaka ngevacuum (i-vacuum drying), inaliti ye-electrolyte, ukuguga, kunye nokwakheka.
Into iqokobhe
Kubhekiselele ekupakisheni iseli egqityiweyo kwiqokobhe le-aluminium ukuze kube lula ukongezwa kwe-electrolyte kunye nokukhusela ukwakheka kweeseli.
Vacuum yokubhaka (ivacuum drying)
Njengoko kwaziwa kubo bonke, amanzi ayabulala kwiibhetri ze-lithium. Oku kungenxa yokuba xa amanzi edibana ne-electrolyte, i-hydrofluoric acid iya kwenziwa, enokubangela umonakalo omkhulu kwibhetri, kwaye igesi eveliswayo iya kubangela ukuba ibhetri iqhume. Ke ngoko, amanzi angaphakathi kwiseli yebhetri ye-lithium-ion kufuneka asuswe kwindibano yocweyo ngaphambi kokuba i-electrolyte ifakwe ukuphepha ukuchaphazela umgangatho webhetri ye-lithium-ion.
Ukubhaka i-vacuum kubandakanya ukuzaliswa kwe-nitrogen, ukucoca, kunye nokufudumeza okuphezulu kobushushu. Ukuzaliswa kwe-nitrojeni kukutshintsha umoya kunye nokuphula i-vacuum (uxinzelelo olubi lwexesha elide luya kulimaza izixhobo kunye nebhetri. Ukuzaliswa kwe-nitrogen kwenza ukuba uxinzelelo lomoya lwangaphakathi nangaphandle lulingane ngokulinganayo) ukuphucula i-conductivity ye-thermal kunye nokuvumela amanzi ukuba aphephe kangcono. Emva kwale nkqubo, ukufuma kwebhetri ye-lithium-ion kuvavanywa, kwaye inkqubo elandelayo inokuqhubeka kuphela emva kokuba ezi seli ziphumelele uvavanyo.
Isitofu se-Electrolyte
Isitofu sibhekisa kwinkqubo yokutofa i-electrolyte ebhetrini ngokuhambelana nexabiso elifunekayo ngomngxuma wokutofa ebekelwe bucala. Yahlulwe kwinaliti yokuqala kunye nenaliti yesibini.
Ukuguga
Ukuguga kubhekisela ekubekweni emva kwentlawulo yokuqala kunye nokubunjwa, okunokwahlulwa ngokuguga okuqhelekileyo kweqondo lokushisa kunye nokuguga okuphezulu. Inkqubo yenziwa ukwenza iipropati kunye nokubunjwa kwefilimu ye-SEI eyenziwe emva kokuhlawulwa kokuqala kunye nokwakheka okuzinzile, ukuqinisekisa ukuzinza kwe-electrochemical yebhetri.
Formation
Ibhetri ivulwa kwitshajiso yokuqala. Ngethuba lenkqubo, ifilimu esebenzayo (ifilimu ye-SEI) yenziwa phezu kwe-electrode engafanelekanga ukufezekisa "ukuqaliswa" kwebhetri ye-lithium.
Ukuhlelwa
Ukuhlelwa, oko kukuthi, "uhlalutyo lwamandla", kukuhlawula kunye nokukhupha iiseli emva kokubunjwa ngokwemigangatho yokuyila ukuvavanya amandla ombane weeseli kwaye zibekwe ngokwamandla azo.
Kuyo yonke inkqubo yokubuyela emva, ukubhaka i-vacuum yeyona nto ibalulekileyo. Amanzi "yintshaba yendalo" yebhetri ye-lithium-ion kwaye ihambelana ngokuthe ngqo nomgangatho wabo. Ukuphuhliswa kweteknoloji yokumisa i-vacuum ixazulule ngokufanelekileyo le ngxaki.
Dacheng ukuchaneka vacuum dry imveliso series
Umgca we-vacuum wokumisa umgca wokuchaneka kwe-Dacheng uneemveliso ezintathu eziphambili: i-oven yokubhaka i-vacuum, i-oven yokubhaka i-monomer, kunye ne-oven yokuguga. Ziye zisetyenziswe ngabavelisi bebhetri be-lithium abaphezulu kwishishini, bafumana indumiso ephezulu kunye neempendulo ezilungileyo.
I-Dacheng Precision ineqela labasebenzi abaqeqeshiweyo be-R&D abanenqanaba eliphezulu lobugcisa, isakhono esikhulu sokwenza izinto ezintsha kunye namava atyebileyo. Ngokubhekiselele kwitekhnoloji yokumisa i-vacuum, i-Dacheng Precision iphuhlise uchungechunge lwetekhnoloji ephambili ebandakanya itekhnoloji yokudibanisa i-multi-layer fixture, iinkqubo zokulawula ubushushu, kunye nezithuthi ezijikelezayo zokulayisha ukuhambisa iinkqubo ze-oven yokubhaka i-vacuum, kunye neenzuzo zayo eziphambili zokukhuphisana.
