Lithium-ion bhatiri yekugadzira maitiro: yepakati-nhanho maitiro

Sezvatakambotaura, yakajairika lithium-ion bhatiri yekugadzira maitiro inogona kukamurwa kuita nhanho nhatu: yekumberi-yekupedzisira maitiro (electrode kugadzira), yepakati-nhanho nhanho (sero synthesis), uye kumashure-yekupedzisira maitiro (kuumbwa uye kurongedza). Isu takambozivisa iyo yekumberi-yekupedzisira maitiro, uye chinyorwa ichi chinotarisa pane yepakati-nhanho maitiro.

Iyo yepakati-nhanho maitiro ekugadzira lithium bhatiri chikamu chegungano, uye chinangwa chayo chekugadzira ndechekupedzisa kugadzirwa kwemasero. Kunyanya, iyo yepakati-nhanho maitiro ndeyekuunganidza iyo (yakanaka uye yakaipa) maelectrode akaitwa mune yapfuura muitiro nemuparadzi uye electrolyte nenzira yakarongeka.

Nekuda kweakasiyana masimba ekuchengetedza mabhatiri emhando dzakasiyana dzemabhatiri e-lithium anosanganisira prismatic aluminium shell bhatiri, cylindrical bhatiri uye pouch bhatiri, blade bhatiri, zvichingodaro, pane misiyano iri pachena muhunyanzvi hwavo hwekuita mukati mechikamu chepakati.

Iyo yepakati-nhanho maitiro eprismatic aluminium shell bhatiri uye cylindrical bhatiri iri mhepo, electrolyte jekiseni uye kurongedza.

Iyo yepakati-nhanho maitiro ehomwe bhatiri uye blade bhatiri iri stacking, electrolyte jekiseni uye kurongedza.

Musiyano mukuru pakati pezviviri ndeyekupeta muitiro uye stacking muitiro.

Winding

Iyo cell winding process ndeyekutenderedza cathode, anode uye separator pamwe chete kuburikidza nemhepo inomonereka muchina, uye iri padyo necathode uye anode inoparadzaniswa neinoparadzanisa. Muchikamu chelongitudinal chesero, muparadzi anodarika anode, uye anode inodarika cathode, kuitira kudzivirira kupfupika-kutenderera kunokonzerwa nekubatana pakati pecathode uye anode. Mushure mekuputika, sero rinogadziriswa ne tepi yekunamatira kuti irege kuparara. Ipapo sero rinoyerera kune rinotevera muitiro.

Mukuita uku, zvakakosha kuve nechokwadi kuti hapana kubatwa kwepanyama pakati peakanaka neasina kunaka maelectrode, uye kuti electrode isina kunaka inogona kuvhara zvachose iyo yakanaka electrode mumativi ese akatwasuka uye akachinjika.

Nekuda kwehunhu hwekuita mhepo, inogona chete kushandiswa kugadzira lithium mabhatiri ane chimiro chenguva dzose.

Stacking

Kusiyana neizvi, iyo stacking process inorongedza maelectrode akanaka uye asina kunaka uye anoparadzanisa kuti aite stack cell, inogona kushandiswa kugadzira lithium mabhatiri enguva dzose kana abnormal shapes. Iine mwero wepamusoro wekushanduka.

Kuturikidzana kunowanzo muitiro wekuti maelectrode akanaka neasina kunaka uye muparadzi akaturikidzana dandemutande muhurongwa hwepositive electrode-separator-negative electrode kuumba stack cell nemuunganidzi aripo.sematebhu. Kuturikidzana nzira dzinobva kune yakananga stacking, umo muparadzi anogurwa, kusvika kuZ-kupeta umo muparadzi asina kugurwa uye akaturikidzana mune z-chimiro.

Muchigadziro chekugadzirisa, hapana kukotama chiitiko cheiyo electrode sheet, uye hapana "C kona yekona" dambudziko rinosangana mukuita mhepo. Naizvozvo, nzvimbo yekona mugomba remukati inogona kushandiswa zvizere, uye huwandu hwevhoriyamu yeyuniti yakakwirira. Kuenzaniswa nemabhatiri e-lithium anogadzirwa nekuita mhepo, mabhatiri e-lithium anogadzirwa nekurongedza maitiro ane mabhenefiti ari pachena mukuwanda kwesimba, chengetedzo, uye mashandiro ekuburitsa.

The winding process ine yakati rebei budiriro nhoroondo, mature process, low cost, high goho. Nekudaro, nekuvandudzwa kwemotokari nyowani dzesimba, hurongwa hwekututira hwave nyeredzi inosimuka ine yakakwira vhoriyamu kushandiswa, yakagadzikana chimiro, kuderera kwemukati kuramba, hupenyu hurefu hwekutenderera uye zvimwe zvakanaka.

Kungave kuri kumonereka kana kurongedza maitiro, ese ari maviri ane mabhenefiti ari pachena uye akashata. Stack bhatiri inoda akati wandei kucheka-kubvisa kwe electrode, zvichikonzera kureba kwemuchinjiko-chikamu saizi pane inomonereka chimiro, ichiwedzera njodzi yekukonzera maburrs. Kana iri bhatiri rinomonereka, makona ayo achaparadza nzvimbo, uye kusaenzana kwemhepo kushushikana uye deformation inogona kukonzera unhomogeneity.

Naizvozvo, inotevera X-ray bvunzo inova yakakosha zvakanyanya.

X-ray kuongorora

Iyo yakapedzwa mhepo uye stack bhatiri inofanirwa kuongororwa kuti itarise kana chimiro chavo chemukati chinopindirana nemaitiro ekugadzira, senge kurongeka kwematanho kana maseru anomonereka, chimiro chemukati chematebhu, uye overhang yeakanaka uye yakaipa electrode, nezvimwewo, kuitira kudzora zvigadzirwa zvemhando uye kudzivirira kuyerera kwemasero asina kukodzera kupinda maitiro anotevera;

Yekuongorora X-Ray, Dacheng Precision yakatanga nhevedzano yeX-Ray imaging yekuongorora michina:
