Njengoko sichazile ngaphambili, inkqubo yokuvelisa ibhetri ye-lithium-ion eqhelekileyo inokwahlulwa ibe ngamanqanaba amathathu: inkqubo ye-front-end (imveliso ye-electrode), inkqubo yenqanaba eliphakathi (i-cell synthesis), kunye nenkqubo yokuphela (ukuqulunqwa kunye nokupakishwa). Ngaphambili sazisa inkqubo ye-front-end, kwaye eli nqaku liza kugxininisa kwinkqubo yenqanaba eliphakathi.
Inkqubo yenqanaba eliphakathi lokuvelisa ibhetri ye-lithium licandelo lendibano, kwaye injongo yalo yokuvelisa kukugqiba ukuveliswa kweeseli. Ngokukodwa, inkqubo yenqanaba eliphakathi kukuhlanganisa i-electrode (elungileyo kunye nembi) eyenziwe kwinkqubo yangaphambili kunye ne-separator kunye ne-electrolyte ngendlela ehlelekile.
Ngenxa yezakhiwo ezahlukeneyo zokugcina amandla eentlobo ezahlukeneyo zeebhetri ze-lithium ezibandakanya ibhetri ye-aluminium ye-prismatic, ibhetri ye-cylindrical kunye nebhetri ye-pouch, ibhetri ye-blade, njl., kukho umahluko ocacileyo kwinkqubo yabo yobugcisa kwinkqubo ephakathi.
Inkqubo yenqanaba eliphakathi yebhetri ye-aluminium yeprismatic kunye nebhetri yecylindrical iyajikajika, inaliti ye-electrolyte kunye nokupakishwa.
Inkqubo yenqanaba eliphakathi yebhetri yesingxobo kunye nebhetri yeblade is stacking, inaliti ye-electrolyte kunye nokupakishwa.
Umahluko ophambili phakathi kwezi zimbini yinkqubo yokujija kunye nenkqubo yokupakisha.
Ukugquma
Inkqubo yokujija iseli kukuqengqeleka i-cathode, i-anode kunye ne-separator kunye ngomatshini wokujija, kwaye i-cathode esecaleni kunye ne-anode yahlulwe yi-separator. Kwicala le-longitudinal yeseli, isahluli sidlula i-anode, kwaye i-anode idlula i-cathode, ukwenzela ukuba kuthintelwe i-short-circuited ebangelwa ukudibanisa phakathi kwe-cathode kunye ne-anode. Emva kokujija, iseli igxininiswe yi-tape yokubambelela ukukhusela ukuba ingawa. Emva koko iseli iphumela kwinkqubo elandelayo.
Kule nkqubo, kubalulekile ukuqinisekisa ukuba akukho mdibaniso womzimba phakathi kwee-electrode ezilungileyo kunye ne-negative, kwaye i-electrode e-negative inokuvala ngokupheleleyo i-electrode efanelekileyo kuzo zombini izikhokelo ezithe tye kunye nezithe nkqo.
Ngenxa yeempawu zenkqubo yokucima, ingasetyenziselwa kuphela ukwenza iibhetri ze-lithium ezinemilo eqhelekileyo.
Ukupakisha
Ngokwahlukileyo, inkqubo yokupakisha ibeka i-electrode echanekileyo kunye ne-negative kunye ne-separator ukwenza i-cell stack, engasetyenziselwa ukuvelisa iibhetri ze-lithium zemilo eqhelekileyo okanye engaqhelekanga. Ineqondo eliphezulu lokuguquguquka.
Ukupakisha kudla ngokuba yinkqubo apho i-electrode elungileyo kunye nengalunganga kunye nesahluli zipakishwe umaleko ngokomaleko ngokulandelelana kwe-electrode-positive-separator-negative electrode ukwenza isitakhi seseli kunye nomqokeleli wangoku.njengeethebhu. Iindlela zokupakisha zivela kwi-stacking ngokuthe ngqo, apho isahluli sinqunyulwa khona, ukuya kwi-Z-folding apho isahluli singanqunyulwa kwaye sifakwe kwi-z-shape.
Kwinkqubo yokupakisha, akukho nto yokugoba kwiphepha elifanayo le-electrode, kwaye akukho ngxaki "yekona ye-C" edibene nayo kwinkqubo yokucima. Ngoko ke, indawo yekona kwigobolondo yangaphakathi inokusetyenziswa ngokupheleleyo, kwaye umthamo weyunithi nganye uphezulu. Xa kuthelekiswa neebhetri ze-lithium ezenziwe ngenkqubo yokuphefumula, iibhetri ze-lithium ezenziwe ngenkqubo yokupakisha zineenzuzo ezicacileyo kubuninzi bamandla, ukhuseleko, kunye nokusebenza kokukhutshwa.
Inkqubo yokujija inembali yophuhliso ende, inkqubo evuthiweyo, ixabiso eliphantsi, isivuno esikhulu. Nangona kunjalo, ngokuphuhliswa kwezithuthi zamandla amatsha, inkqubo yokupakisha ibe yinkwenkwezi ekhulayo kunye nokusetyenziswa komthamo ophezulu, isakhiwo esizinzile, ukuchasana okuphantsi kwangaphakathi, ubomi bomjikelezo omde kunye nezinye iingenelo.
Nokuba yinkqubo yokujija okanye ukupakisha, zombini zineengenelo ezicacileyo kunye nezingeloncedo. Ibhetri ye-Stack ifuna ukunqunyulwa kwee-electrode ezininzi, okukhokelela kubukhulu becandelo elide elinqamlezayo kunesakhiwo esijikelezayo, kwandisa umngcipheko wokubangela i-burrs. Ngokubhekiselele kwibhetri ejikelezayo, iikona zayo ziya kuchitha isithuba, kwaye ukuxinezeleka okungahambelaniyo kunye nokuguqulwa kunokubangela uhomogeneity.
Ke ngoko, uvavanyo olulandelayo lweX-reyi luba lubaluleke kakhulu.
Uvavanyo lweX-reyi
Ukugqitywa kokugqitywa kunye ne-stack ibhetri kufuneka kuhlolwe ukujonga ukuba isakhiwo sazo sangaphakathi sihambelana nenkqubo yokuvelisa, njengokulungelelaniswa kwe-stack okanye iiseli ezijikelezayo, isakhiwo sangaphakathi seethebhu, kunye nokugqithisa kwee-electrodes ezintle kunye ezimbi, njl., ukwenzela ukulawula umgangatho weemveliso kunye nokuthintela ukuhamba kweeseli ezingafanelekanga kwiinkqubo ezilandelayo;
Kuvavanyo lwe-X-Ray, i-Dacheng Precision yasungula uluhlu lwezixhobo zokuhlola umfanekiso we-X-Ray:
