Pakutanga, isu takaunza yekumberi-yekupedzisira uye yepakati-nhanho maitiro ekugadzira lithium bhatiri mune zvakadzama. Ichi chinyorwa chicharamba chichiunza maitiro ekumashure.
Chinangwa chekugadzira chekumashure-yekupedzisira maitiro ndechekupedzisa kuumbwa uye kurongedza kwe lithium-ion bhatiri. Muchikamu chepakati-chepakati, chimiro chekushanda kwesero chakaumbwa, uye masero aya anofanira kushandiswa mune imwe nguva inotevera. Maitiro makuru mumatanho ekupedzisira anosanganisira: mugoko, vacuum baking (vacuum drying), jekiseni re electrolyte, kuchembera, uye kuumbwa.
Into shell
Zvinoreva kurongedza sero rakapedzwa mugoko realuminium kuti rifambise kuwedzera kwe electrolyte uye kuchengetedza sero chimiro.
Vacuum baking (vacuum drying)
Sezvinozivikanwa kune vese, mvura inouraya kune lithium mabhatiri. Izvi zvinodaro nekuti kana mvura ikasangana ne electrolyte, iyo hydrofluoric acid inoumbwa, inogona kukonzera kukuvadzwa kukuru kwebhatiri, uye gasi rinogadzirwa rinoita kuti bhatiri riwedzere. Naizvozvo, mvura iri mukati melithium-ion bhatiri sero inoda kubviswa mumusangano wemusangano pamberi pejekiseni reelectrolyte kudzivirira kunaka kwe lithium-ion bhatiri.
Vacuum kubika kunosanganisira nitrogen kuzadza, vacuuming, uye yakakwirira-tembiricha kupisa. Kuzadza nitrojeni ndiko kutsiva mhepo uye kuputsa vacuum (kurebesa kusina kunaka kunokanganisa midziyo uye bhatiri. Kuzadza nitrogen kunoita kuti mukati nekunze kwemhepo kuenzane kuenzana) kunatsiridza kupisa kwekushisa uye kubvumira mvura kuti iwedzere zviri nani. Mushure mekuita uku, hunyoro hwelithium-ion bhatiri inoedzwa, uye iyo inotevera nzira inogona kungoenderera mberi mushure mekunge masero aya apfuura bvunzo.
Electrolyte injection
Jekiseni inoreva nzira yekubaya electrolyte mubhatiri zvichienderana nehuwandu hunodiwa kuburikidza negomba rejekiseni rakachengetwa. Inopatsanurwa kuita jekiseni rekutanga uye jekiseni rechipiri.
Kuchembera
Kuchembera kunoreva kuiswa mushure mekutanga kubhadharisa uye kuumbwa, iyo inogona kukamurwa kuva yakajairika tembiricha kuchembera uye kuchembera kwakanyanya. Iyo nzira inoitwa kuti zvigadziriswe uye kuumbwa kweiyo SEI firimu yakaumbwa mushure mekutanga kubhadharisa uye kuumbwa kwakasimba, kuve nechokwadi chekuti electrochemical kugadzikana kwebhatiri.
Formation
Bhatiri rinoitwa kuburikidza nechaji yekutanga. Munguva yemaitiro, firimu rinoshanda rinoshanda (SEI firimu) rinoumbwa pamusoro peiyo negative electrode kuti iwane "initialization" ye lithium bhatiri.
Grading
Grading, kureva kuti, "capacity analysis", ndeyekuchaja uye kuburitsa maseru mushure mekuumbwa zvinoenderana nemaitiro ekugadzira kuyedza kugona kwemagetsi emaseru uye anobva aiswa magiredhi zvichienderana nekugona kwawo.
Mune yese yekumashure-yekupedzisira maitiro, vacuum baking ndiyo inonyanya kukosha. Mvura ndiyo "muvengi wechisikigo" we lithium-ion bhatiri uye yakanangana nemhando yavo. Kuvandudzwa kwevacuum drying tekinoroji kwakagadzirisa dambudziko iri.
Dacheng chaiyo vacuum kuomesa chigadzirwa akatevedzana
Vacuum yekuomesa zvigadzirwa mutsara weDacheng chaiyo ine matatu makuru echigadzirwa akateedzana: vacuum yekubheka tunnel oveni, vacuum kubika monomer oveni, uye kuchembera oveni. Izvo zvakashandiswa nevagadziri vepamusoro lithium bhatiri muindasitiri, vachigamuchira kurumbidzwa kukuru uye mhinduro yakanaka.
Dacheng Precision ine boka revashandi veR&D vane hunyanzvi hwepamusoro, kugona kukuru kwekuvandudza uye ruzivo rwakapfuma. Panyaya yevacuum yekuomesa tekinoroji, Dacheng Precision yakagadzira akateedzana epakati matekinoroji anosanganisira akawanda-layer fixture yekubatanidza tekinoroji, tembiricha yekudzora masisitimu, uye inotenderera inotakura mota dzinotumira masisitimu evacuum yekubikira oveni, ine zvakakosha zvemakwikwi.
