Nakhu kufika i-hardcore! Ikuyise ekuqondeni okuphelele kokuhlolwa kokungena kwezinzipho zebhethri le-lithium.
Izimoto ezintsha zamandla ziyizikhombisi-ndlela zokuthuthukiswa kwezimoto zesikhathi esizayo, futhi enye yezingxenye eziyinhloko zezimoto ezintsha zamandla ibhethri lamandla. Njengamanje, kunezinhlobo ezimbili eziyinhloko emakethe: i-ternary lithium ne-lithium iron phosphate. Iyiphi kulezi zinhlobo ezimbili zamabhethri esebenza kakhulu futhi ephephile? Ngaphambilini, ibhethri yeblade ye-BYD inikeze impendulo ngamandla ayo anamandla okuqamba kanye nokuqongelela okujulile kobuchwepheshe. Manje, ukuphepha okuphezulu kakhulu kwebhethri ye-Kenergy lithium kunqobe "i-Mount Everest" yensimu yokuhlola ibhethri - ukuhlolwa kokungena kwezipikili. Namuhla, ngizokhuluma ngokuphepha kwamabhethri e-lithium ngokusekelwe ekuhlolweni kokungena kwezipikili kwebhethri ye-Kenergy lithium.
Ngaphambi kokukhuluma ngokuhlolwa kokungena kwezinzipho, ake ngiqale ngichaze izindlela zamanje zokuhlola ezijwayelekile zikazwelonke zokuphepha kwebhethri. Ezimfuneko ezijwayelekile zikazwelonke zokuphepha kwebhethri, izingozi ezibangelwa amabhethri anamandla ezimoto zikagesi, amaphakethe amabhethri, noma amasistimu ahlanganisa: (1) ukuvuza, okungase kuholele kumandla kagesi aphezulu wesistimu yebhethri kanye nokwehluleka kokufakwa kwamanzi, okubangela ngokungaqondile izisebenzi zikagesi. ukushaqeka, umlilo wesistimu yebhethri, nezinye izingozi; (2) umlilo, oshisa umzimba womuntu ngokuqondile; (3) ukuqhuma, okufaka umzimba womuntu engozini ngokuqondile, okuhlanganisa ukusha kwezinga lokushisa eliphezulu, ukulimala kwamagagasi okwethuka, nokulimala kwezingcezu zokuqhuma, njll.; (4) ukushaqeka kukagesi, okubangelwa ukudlula kwamanje emzimbeni womuntu.
Kungani kudingekile ukuhlolwa kokungena kwezinzipho?
Ngokusho kwedatha efanelekile, ukuthatha izingozi zesikhathi esidlule zezimoto zamandla amasha njengesibonelo, iningi lezingozi zokusha ezizenzakalelayo ezihlobene namabhethri zihlobene eduze nokugijima okushisayo kwamaseli ebhethri. Ngakho-ke, yini i-thermal runaway? Ukushisa okushisayo kwebhethri kubhekisela esimweni lapho izinga lokukhiqiza ukushisa lokusabela kwamakhemikhali angaphakathi ebhethri liphezulu kakhulu kunezinga lokushabalalisa ukushisa. Inani elikhulu lokushisa linqwabelana ngaphakathi kwebhethri, okwenza izinga lokushisa lebhethri likhuphuke ngokushesha, futhi ekugcineni libangele ukuthi ibhethri libambe umlilo noma liqhume.
Ukuhlolwa kokungena kwezinzipho kungalingisa kokubili amasekhethi amafushane angaphakathi nangaphandle aholela ekubalekeni okushisayo. Njengamanje, kunezimbangela ezimbili ngokuyinhloko zokubaleka okushisayo: eyodwa izimbangela zemishini nezikagesi (njengokungena kwezinzipho, ukushayisana, nezinye izingozi); enye izimbangela ze-electrochemical (njengokushaja ngokweqile, ukushaja okusheshayo, amasekhethi amafushane azenzakalelayo, njll.). Ngemva kokushisa okushisayo kwebhethri elilodwa, lidluliselwa kumaseli aseduze, bese lisakazeka endaweni enkulu, ekugcineni liholele ekwenzeka kwezingozi zokuphepha.
Inqubo yokuhlolwa kokungena kwezipikili ayinzima. Ngokwendlela yokuhlola ukungena kwezinzipho ebalulwe ezingeni likazwelonke, ibhethri idinga ukushajwa ngokugcwele, bese kusetshenziswa inaliti yensimbi ye-tungsten ukuze kungene ibhethri iqonde mpo. Wonke amandla ebhethri azokhishwa endaweni yokungena yezinzipho esikhathini esifushane. Inaliti yensimbi ihlala ebhethrini, futhi ibonwa ihora elilodwa. Kubhekwa njengokufanelekile uma kungekho mlilo noma ukuqhuma. Phakathi kwezivivinyo ezingaphezu kuka-300 zokuphepha kwebhethri le-lithium, ukuhlolwa kokungena kwezinzipho kubonwa njengento eqinile nenzima kakhulu yokuhlola ukuphepha ukuze kufinyelelwe kuyo. Kodwa-ke, ibhethri ye-Kenergy lithium inqobe ngempumelelo ukuhlolwa okunzima kakhulu.
"Ukuphepha okuphezulu" kuyisici esikhulu kunazo zonke sebhethri ye-Kenergy lithium, futhi imiphumela yokuhlola ifakazela lokhu. Ngemva kokungena ngokuphelele ngenaliti, izinga lokushisa eliphakeme kakhulu lebhethri ye-Kenergy lithium lingaphansi kuka-50 ° C, futhi akukho ukusha noma ukuqhuma, futhi akukho ntuthu. Kuyabonakala ukuthi leli bhethri liphephe kakhulu ngaphansi kwezimo zesekethe emfishane.

Ibhethri ye-lithium iron phosphate prismatic esetshenziselwa ukuhlola okuqhathanisayo ayizange ikhiqize ilangabi elivulekile, kodwa kwakunomusi omningi owugqinsi, futhi nokushintsha kwezinga lokushisa kwakusobala kakhulu. Ukusebenza kwelinye ibhethri le-lithium ye-ternary kuyethusa kakhulu: ibhethri libe nokusabela kwamakhemikhali okunobudlova ngesikhathi sokungena kwezinzipho, izinga lokushisa elingaphezulu lebhethri ladlula ngokushesha ku-500 ° C, lase libamba umlilo futhi laqhuma. Uma lokhu kwenzeka ngesikhathi sokushayela kwangempela, ingozi yokuphepha isengaba nkulu kakhulu.

Ibhethri ye-Kenergy lithium iye yabonwa yimboni nabathengi.
Ukuhlolwa kokungena kwebhethri yizinga lebhizinisi lebhethri le-Kenergy lithium. Imikhiqizo yethu futhi inezici zamandla amakhulu, ukubekezela okukhulu, impilo ephezulu, amandla amakhulu, nokumelana okubandayo, okuyisisekelo sobuholi obuqhubekayo bebhethri ye-Kenergy lithium. Ngasikhathi sinye, ibhethri ye-Kenergy lithium iyaqhubeka nokuthengisa okushisayo, okuwukuqinisekisa okukhulu kwabathengi kanye nemakethe ebhizinisini.
Siyakwamukela ku-KELAN Lithium Battery. Isiteshi sethu sikagesi esiphathwayo,Ibhethri ye-LiFePO4 Lithium, futhiIbhethri le-EV elikhanyayowonke amaseli anesici aphumelele ukuhlolwa kokungena kwezinzipho. Zisebenzise ngokuzethemba.
