NgoNovemba 19, Iforamu Yesibili Yokuthuthukiswa Kwezobuchwepheshe Nezimboni yabanjelwa eKunshan. Emcimbini wokuvula wenkundla, i-Qingtao (Kunshan) Energy Development Co., Ltd. imeme izihambeli ukuthi zivakashele ulayini wokuqala wokukhiqiza ibhethri le-lithium e-China. Kubikwa ukuthi lo mugqa wokukhiqiza ungakhiqiza amabhethri e-solid state ayi-2 ngosuku, futhi ukuminyana kwamandla amabhethri kungafinyelela ngaphezu kuka-10,000Wh. Njengamanje, imikhiqizo izosetshenziswa kakhulu emikhakheni esezingeni eliphezulu yedijithali neminye, futhi kulindeleke ukuthi ingene emkhakheni ngo-400 ukuhlinzeka ngamabhethri ezinkampanini zezimoto. Kuthe uma kuphuma lezi zindaba kwacishe kwaduma abantu kulo mkhakha.

Amabhethri e-lithium anamandla afana nenhliziyo yezimoto zikagesi, futhi intengo iphinde ithathe ngaphezu kwesigamu sayo yonke imoto. Ngakho-ke, ubuchwepheshe bebhethri bubaluleke kakhulu ekuthuthukisweni kwemboni entsha yamandla. Uma ibhodlela lamanje lomthamo webhethri le-lithium elisekelwe emanzini alikwazi ukuphulwa, yonke Imboni ingase iwele esimweni esinzima kakhulu. Esikhathini esizayo, hhayi izimoto zomndeni kuphela, kodwa ngisho nezimoto kungase kudingeke zisebenzise amandla kagesi, futhi izidingo zamabhethri zizoba ngaphezulu nakakhulu. Ngakho-ke, amabhethri e-state-state aqinile ane-plasticity ephakeme asephenduke isiqondiso semizamo yezinkampani eziningi, kuhlanganise nezinkampani zezimoto ezidumile emhlabeni jikelele njengeToyota, BMW, Mercedes-Benz, neVolkswagen, kanye nezinkampani ezinkulu ezixhaswe uMnyango Wezindaba Zomnotho. IJapan, isiqalile ukusebenza kulo mkhakha.

Kulo mbukiso womugqa wokukhiqiza we-Kunshan Qingtao Company, abantu babone lokhu: Ngemva kokuthi iphakethe lebhethri elinozipho oluwugqinsi kuphela lisikwe yisikelo, alizange liqhume nje kuphela, kodwa lalinikwe amandla ngendlela evamile. Ngaphezu kwalokho, noma ngabe ibigobile amashumi ezinkulungwane zezikhathi, umthamo webhethri awuzange ubole ngaphezu kuka-5%, futhi ibhethri ayizange ishise noma iqhume ngemva kokutshopa. Eqinisweni, amabhethri e-lithium esimo esiqinile anezinzuzo eziningi. Ngenxa yokuthi ama-electrolyte e-solid state awashi, awashisi, awaguquki, futhi awavuzi, ngeke abangele izenzakalo zokusha okuzenzakalelayo emotweni, okuthuthukisa kakhulu ukuphepha. Impela iwuhlobo lwe-Ideal battery material yezimoto zikagesi.

Njengamanje, izimoto zikagesi ezijwayelekile zivame ukusetshenziswa, empeleni, kuneziphambeko ezithile, ngoba kungakhathaliseki ukuthi isakhiwo samakhemikhali noma isakhiwo sebhethri, i-ternary lithium material kulula kakhulu ukukhiqiza ukushisa. Uma ingcindezi ingakwazi ukudluliselwa ngesikhathi, kunengozi yokuqhuma kwebhethri, futhi iningi lezigameko zokusha okuzenzakalelayo kwezimoto zikagesi ezenzeke kulo nyaka nazo zibangelwa yilokhu. Futhi mayelana nokukhuthazela, ukuminyana kwamandla okukodwa kwamabhethri e-lithium e-ternary okwamanje kubhekene nebhodlela, futhi kunzima ukugqobhoza. Uma ufuna ukwandisa ukuminyana kwamandla, ungakwazi ukwandisa kuphela okuqukethwe kwe-nickel noma wengeze i-CA, kodwa ukuzinza kokushisa kwe-nickel ephezulu kubi kakhulu, futhi kujwayele ukusabela ngobudlova. Ngakho-ke, okwamanje, ukuhwebelana kuphela kungenziwa phakathi komthamo webhethri nokuphepha.

Ngisho nabakwaToyota, abazi kahle kakhulu kwezobuchwepheshe nokucwaninga nokuthuthukiswa kwezobuchwepheshe, bathi amabhethri aqinile ngeke akwazi ukukhiqiza ngobuningi ngo-2030. Kuyabonakala ukuthi kusenezinkinga ocwaningweni nasekuthuthukisweni kwe-solid- amabhethri wombuso. Eqinisweni, njengoba amabhethri e-solid-state engadingi ukungena kwe-liquid futhi adinga kuphela ama-electrolyte aqinile ukuze ahlukanise amapuleti amahle namabi, ukukhethwa kwezinto zensimbi kuba bucayi kakhulu. Inselele enkulu yalobu buchwepheshe ukuthi ukuguquguquka okuphelele kwe-electrolyte eqinile kuphansi kunaleyo ye-electrolyte ewuketshezi, okuholela ekusebenzeni kwesilinganiso esiphansi sebhethri yamanje yesimo esiqinile kanye nokumelana okukhulu kwangaphakathi. Ngakho-ke, ibhethri lesimo esiqinile okwamanje alikwazi ukuhlangabezana nezimfuneko zokushajwa ngokushesha. Dinga. Kodwa-ke, i-conductivity kagesi inobudlelwane obukhulu kakhulu nezinga lokushisa, ngakho-ke ukusebenza ezingeni lokushisa eliphezulu kuzokwenza ibhethri lenze kangcono. Ngaphezu kwalokho, i-conductivity yebhethri kufanele igcinwe ezingeni elijwayelekile, futhi yamanje iphezulu kakhulu noma iphansi kakhulu ingabangela ezinye izinkinga.

Namuhla, ubuchwepheshe bokucwaninga nokuthuthukiswa kwamabhethri e-lithium e-ternary yizinkampani eziholwa yi-Panasonic ne-CATL sezivele zisungulwe kahle. Ngisho noma amabhethri e-lithium e-solid state athuthukiswa ngesikhathi esifushane, kunzima ukufeza ukukhiqizwa ngobuningi. Phela, lapho ubuchwepheshe obusha buya emhlabeni, kuhlala kudingekile ukuthi inkampani ibe nevolumu yomkhiqizo ehambisanayo namandla okukhiphayo ukuze izuze ukukhuthazwa nokusetshenziswa ngezinga elikhulu. Nakuba amabhethri e-lithium akhona manje e-solid state asabhekene nezinkinga eziningi futhi engenayo inzuzo enkulu ekuminyana kwamandla okwamanje, anokuphepha okuphezulu kakhulu. Uma izinto zensimbi ezifanele zingathuthukiswa, mhlawumbe wonke amandla ebhethri le-lithium Imboni izoletha impumelelo entsha. Yilokhu esifuna ukukubona. Phela, ucwaningo olungaguquki luwumoya weqiniso wocwaningo lwesayensi. Isilinganiso sokuminyana kwamandla sisho umthamo webhethri ngeyunithi yesisindo. I-Cylindrical monomer ibalwa ngokuya ngesilinganiso sasekhaya esijwayelekile esingu-18650 (1.75AH), isilinganiso sokuminyana kwamandla singafinyelela ku-215WH/Kg, futhi i-monomer yesikwele ibalwa ngokuya ngo-50AH futhi isilinganiso sokuminyana kwamandla singafinyelela ku-205WH/Kg. Izinga lokuqoqwa kwesistimu lizungeze u-60% ngo-18650, futhi isikwele sizungeze u-70%. (Izinga lokuqoqwa kwesistimu lingacatshangwa ngokufaka i-ham ebhokisini. Igebe phakathi kwama-square hams lincane, ngakho izinga lokuqoqwa kwesistimu liphezulu.)

Ngale ndlela, isilinganiso sokuminyana kwamandla wesistimu yephakethe yebhethri engu-18650 silinganiselwa ku-129WH/Kg, futhi isilinganiso sokuminyana kwamandla wesistimu yephakethe lebhethri eliyisikwele silinganiselwa ku-143WH/Kg. Lapho isilinganiso sokuminyana kwamandla ka-18650 namaseli ayisikwele sifinyelela okufanayo ngokuzayo, amaphakethe ebhethri e-lithium ayisikwele anezinga eliphezulu lokuqoqa ayoba nezinzuzo ezisobala kakhudlwana.

Ukumaketha

Izinga lokushaja/lokukhipha=ukushaja/khipha umthamo wamanje/olinganisiwe, izinga eliphezulu kakhulu, sishesha isivinini sokushaja esisekelwa ibhethri. Ibhethri lamandla elivundlile elikhiqizwa ekhaya elijwayelekile elingu-18650 licishe libe ngu-1C, futhi isikwele singafinyelela cishe ku-1.5-2C (ngokuphathwa kahle kokushisa), futhi lisekhona ibanga elithile ukusuka ekuhlosweni kwenqubomgomo engu-3C. Nokho, kungenzeka ngokuphelele ukuthi inqubo yokukhiqiza isikwele izoba iphelele kakhulu ukuze kuzuzwe okuhlosiwe okuhlosiwe okungu-3C.
