Uhlolojikelele:
I-Crush ilula kakhuluejwayelekileukuhlola ukuze kuqinisekiswe ukuphepha kwe-cells, elingisa ukushayisana kwe-cellsnoma umkhiqizo wokugcinasekusetshenzisweni kwansuku zonke. Ngokuvamile kunezinhlobo ezimbili zechobozaizivivinyo: flatchobozafuthi ingxenyechoboza. Uma kuqhathaniswa nefulethichoboza, ingxenyeukuhlehlisaokubangelwa i-indenter eyindilinga noma eyi-cylindrical cishe kubangeleiseli engasebenzi. Lapho i-indenter ibukhali, yilapho ingcindezi igxila kakhulu esakhiweni esiyinhloko sebhethri ye-lithium, kulapho kugqashuka khona ingaphakathi.umnyombo, okuzodala ukuwohloka nokugudluzwa komnyombo, futhi kuholele emiphumeleni engathi sína njengokuvuza kwe-electrolyte noma ngisho nomlilo. Pho kwenzeka kanjanichobozakuholele kuukuvala ukusebenzakwe cell? Laphasikwethulela ekuthuthukisweni kwesakhiwo sangaphakathi somongo ekuhlolweni kwe-extrusion kwasendaweni.
Gcobainqubo:
- Amandla okukhama asetshenziswa endaweni ebiyelwe yiseli kuqala, bese kuthi indawo ebiyelwe ikhubazeke. Amandla abe esedluliselwa ngaphakathi kwebhethri, futhi ukuhlanganiswa kweseli nakho kuqala ukonakala.
- Ngokucindezelwa okwengeziwe kwekhanda elichotshozwayo, i-deformation iyanda futhi kwakhiwa indawo. Ngesikhathi esifanayo, isikhala sesendlalelo phakathi kwesendlalelo ngasinye se-electrode sifinyezwa kancane kancane. Ngaphansi kokucindezelwa okuqhubekayo, umqoqi wamanje ugobile futhi ukhubazekile, futhi amabhande okugunda ayakhiwa. Lapho ukuguqulwa kwezinto ze-electrode kufinyelela umkhawulo, impahla ye-electrode izokhiqiza imifantu.
- Ngokukhula kwe-deformation, ukuqhekeka kancane kancane kudlulela kumqoqi wamanje, okuzodatshulwa futhi kukhiqize ukuphuka kwe-ductile. Ngaphezu kwalokho, ukuqhekeka kwe-radial kunwetshiwe ngenxa yokwanda kokucindezeleka nokuhamba kwe-radial.
- Kuleli qophelo, amandla e-extrusion ayaqhubeka nokucindezela ingqamuzana, okwenza izingqimba eziningi zama-electrode zibe nokuwohloka, okuholela ekwandeni kwendawo yokugunda, ukuguquka kwe-engeli yokuthambekela (45°), nokwanda okuqhubekayo kobubanzi bendawo yokugunda.
- Ekugcineni, njengoba i-diaphragm iqhubeka nokunwetshwa nokusonteka, imifantu ifinyelela ku-diaphragm. Uma ifika endaweni yokuvala ukusebenza, i-diaphragm iyadatshulwa futhi ama-electrode aseduze ahlangane, enze i-short-circuit yangaphakathi. Kuleli qophelo, umthamo omkhulu we-short-circuit current ukhiqizwa endaweni ye-short-circuit, okuholela ekushiseni okunamandla nokwenyuka ngokushesha kwezinga lokushisa, okuzobangela ukusabela kwezinhlangothi ngaphakathi kweseli futhi ekugcineni kungase kwenzeke ukuhlukumeza okushisayo.
Isifinyezo:
Ukuhlolwa kwe-Crush kuwuhlobo lokuhlukumeza komshini. Ukuhlukunyezwa kwemishini kuyingozi yokuphepha engenakugwenywa ekusetshenzisweni kwansuku zonke kwamabhethri e-lithium-ion, okungaholela ekuqhekekeni kwe-diaphragm futhi kubangele ukujikeleza okufushane kwangaphakathi. Kodwa-ke, ngenxa yokuma kwekhanda elichotshoziwe, ubukhulu bokucindezela kokuchotshozwa namandla esitokisi ngokwawo kuyahlukahluka, imiphumela yokuhlolwa kwe-crush ngokuvamile ihluka kakhulu. Ukuthuthukiswa kokubalulekile kweseli noma ukwakheka kuyadingeka ukuze kugwenywe ukwenziwa kungasebenzi kweseli okulethwe ukuhlolwa kokuchotshozwa okuningi ngangokunokwenzeka. Isibonelo, ukusetshenziswa kwe-diaphragm ephephile, ene-ductile eyengeziwe noma ukuthuthukiswa kokusebenza kokukhipha ukushisa kweseli kungavimbela kakhulu ukuhlukumeza okushisayo uma kwenzeka i-short-circuit yangaphakathi.
