Isingeniso:
Njengamanje, kunenkinga evamile emotweni entsha yamandla kanyeibhethri le-lithiumizimakethe zokugcina amandla, futhi lokho ukwesaba ukubanda. Ngaphandle kwesinye isizathu ngaphandle kwezimo eziphansi kwezinga lokushisa, ukusebenza kwamabhethri e-lithium kuncipha kakhulu, okubonisa ukulahlekelwa okukhulu kwamandla namandla, ubunzima bokushaja, njll., noma ngisho nokwehluleka ukusebenza kahle.
Lapho kunezindawo ezibuhlungu khona, kunamathuba amakhulu okuthuthukiswa. Ibhethri eliyingqayizivele le-Xingdong Lithium Battery elinokushisa okuphansi lenzelwe "ukubanda". Ngomhlaka-8 Agasti, esithangamini se-"2024 China Energy Storage Industry Ecological Conference" ngosuku lwe-2024 World Battery and Energy Storage Industry Expo, i-Xingdong Lithium Battery yethule amabhethri amane asebenza kahle kakhulu angamelani nokushisa okuphansi ane-charge ephezulu kanye nokusebenza kahle kokukhipha okungaphezu kuka-97%, okwalungisa ukushiyeka kwamabhethri e-lithium iron phosphate futhi kwaqinisekisa ukuthi amabhethri e-lithium iron phosphate nawo angasebenza kahle nangokuzinzile ngaphansi kwezimo zezulu ezibandayo.
Ungakunqoba kanjani izinga lokushisa eliphansi lebhethri le-lithium?
"Ngaphansi kwezimo zokushisa eziphansi, izinga lokusabela kwamakhemikhali ngaphakathi kwebhethri liyehla futhi ijubane lokunyakaza kwama-ion ku-electrolyte liyehla, okuthintaamabhethri e-lithiumukushaja nokusebenza kahle kokukhipha. Ngaphezu kwalokho, amazinga okushisa aphansi angase abangele izinguquko esakhiweni sezinto ezingaphakathi kwebhethri, ngaleyo ndlela kuthinte ukusebenza kanye nokuphila kwebhethri." ULi Jia, umongameli webhizinisi lamazwe ngamazwe le-Xingdong Lithium Battery, uthe ukuze kuxazululwe inkinga yokusebenza kwamabhethri okushisa okuphansi, isihluthulelo ukuthuthukisa izinto ezinokubekezelela amazinga okushisa aphansi.
Kusukela ezintweni zokwakha nakwezinye izici, i-Xingdong Lithium Battery inqobe ubunzima futhi yathuthukisa ngempumelelo ubuchwepheshe obuningi obunelungelo lobunikazi. Iphinde yakhiqiza ngempumelelo ama-4 aphansi okushisa ngobuningi.amabhethri e-lithiumezingashajwa futhi zikhishwe ezindaweni eziphansi zokushisa ezingu--20℃, -25℃, -30℃, kanye no-35℃, ezinobubanzi bomthamo obungu-206Ah kuya ku-314Ah, kanye nokusebenza kahle kokushaja nokukhipha okuhambisanayo okungaphezu kuka-97%, 95%, 95%, kanye no-90%, ngokulandelana, okuhola imboni.
Uma sibhekisisa imfihlo, sizothola ukuthi inhlanganisela yegolide yebhethri le-Xingdong lithium "4+N" idlale indima ebalulekile. I-4 ibhekisela kubuchwepheshe obune obuyinhloko, kanti i-N ibhekisela kubuchwepheshe obuningi obunelungelo lobunikazi obusetshenziswa ngokuhlanganiswa:
1. Ngokuhlanganisa ama-carbon nanotubes kanye ne-graphene,ibhethri le-lithiumImpedance incishisiwe kakhulu, ukumelana kwangaphakathi kungu-≤0.25mΩ, ukusebenza kwesilinganiso kuthuthukisiwe kakhulu, futhi ingasekela ukukhishwa kwamanje okungu-15C ngokushesha;
2. Ubuchwepheshe bokumboza i-diaphragm obunelungelo lobunikazi buyasetshenziswa ukwenza ingxenye yensika iboshwe kakhulu ngesikhathi sokusebenza, okuthuthukisa ngempumelelo ukuphepha kwebhethri kanye nokusebenza komjikelezo;
3. I-electrolyte yejeli enelungelo lobunikazi etholakala endaweni ethile iyasetshenziswa, bese kufakwa i-initiator kanye ne-coagulant ehambisana nebhethri le-lithium iron phosphate ukuze kwenziwe ibhethri imelane kakhulu nokushisa okuphansi, futhi ububanzi bokushisa kokusebenza kwebhethri bungafinyelela ku--35℃～60℃;
4. Inqubo yokufaka inqwaba iyamukelwa, uma kuqhathaniswa nenqubo yokugoqa yendabuko, ukumelana kwangaphakathi kuncishiswa ngo-30%, ngokuqina okungcono kwesakhiwo, ukuphepha okuphezulu, impilo yomjikelezo omude, kanye nobuningi bamandla ≥180Wh/kg;
5. Ngama-patents angu-43 okusungula izinto ezintsha, uhlelo lwe-lithium iron phosphate luyasetshenziswa, luhlanganiswe nezinqubo ezihlukile, futhi imigqa yokukhiqiza ezenzakalelayo ngokuphelele kanye neyokucacisa okuphezulu isetshenziselwa ukuqinisekisa ukuvumelana okuphezulu kwamaseli ebhethri, futhi izokhuthaza ukuthuthukiswa okuqhubekayo kanye nokuphindaphinda kwemikhiqizo.
Umthelela embonini yamabhethri e-lithium
Ezingeni lobuchwepheshe, amabhethri amaningi emakethe okwamanje angasebenza ezingeni lokushisa elingu--20℃ ~ 60℃, kuyilapho izinga lokushisa eliphansi le-Xingdong Lithium Batteryibhethri le-lithiumingasebenza ebangeni lokushisa elingu--35℃～60℃, okuzovuselela ukuthuthukiswa kanye nokusungulwa kobuchwepheshe bebhethri lokushisa eliphansi futhi ihole;
Ezingeni lemboni, i-Xingdong Lithium Battery ibhekana ngenkuthalo nenkinga yamabhethri anokushisa okuphansi futhi yethula imikhiqizo ehamba phambili embonini. Phakathi kwayo, izinga lokushisa eliphansi elingu--35℃ibhethri le-lithiumine-charge kanye nokusebenza kahle kokukhipha amandla okungaphezu kuka-90%, okungagcini nje ngokwakha inzuzo ehlukile, kodwa futhi kusho ukuthi imboni izofinyelela ngempela amalungelo alinganayo kagesi enyakatho naseningizimu, ibe esinye isenzakalo esibalulekile ekuthuthukisweni kobuchwepheshe bebhethri;
Ezingeni lemakethe, enye yezinselelo ezibhekene nemishini yezempi ephakeme njengamanje ukuthi njengoba ukuphakama kokundiza kukhuphuka, indawo ephansi yokushisa ezindaweni eziphakeme ingabangela ukusebenza kwebhethri kwehle; izindawo eziphansi zokushisa ebusika njenge-Inner Mongolia ne-Xinjiang zisebenza kanzima ukukhuthaza ukwakhiwa kwezimayini eziluhlaza; izimakethe zaphesheya kwezilwandle ezifana ne-Europe ne-United States zinezimo zezulu zasebusika ezinzima, amakhono okuxhumanisa igridi abuthakathaka, kanye namanani aphezulu kagesi. Izakhamuzi zidinga ukulinganisa izinhlelo zokugcina amandla eziphansi zokushisa ukuqinisekisa ukusetshenziswa kukagesi okuzinzile ebusika...
Isidingo semakethe sokushisa okuphansi okusebenza kahle kakhuluamabhethri e-lithiumkuyaphuthuma impela, futhi amabhethri e-Xingdong Lithium anokushisa okuphansi awakwazi nje kuphela ukuhlangabezana ngokugcwele nezidingo zezimo zokusetshenziswa ezishiwo ngenhla, kodwa futhi akhiqizwe ngobuningi futhi angasetshenziswa ngokushesha.
Ezingeni lokunciphisa izindleko eziluhlaza, kuphela ngokushayela ubuchwepheshe obusha kanye nokusungula izinto ezintsha kwezimboni lapho singasheshisa khona ukuthuthukiswa komkhiqizo omusha wekhwalithi futhi sifeze kangcono imigomo "yekhabhoni ephindwe kabili". Amabhethri e-Xingdong Lithium anokushisa okuphansi aphula imikhawulo yendawo futhi angasetshenziswa kabanzi ekufakeni ugesi kwemishini yobunjiniyela esindayo, kanye nokugcina amandla/amandla ezindaweni ezinokushisa okuphansi emhlabeni jikelele.
Isiphetho
Sekukonke,izinkampani zamabhethri e-lithiumbebelokhu besabela ngenkuthalo ezinseleleni zemakethe, bethuthuka futhi bephumelela njalo, futhi behlinzeka njalo ngezixazululo zobuchwepheshe ezintsha nezingabizi kakhulu zabantu abafuna amabhethri e-lithium asebenza kahle kakhulu. Kusukela ezinkingeni zamakhasimende, basebenza kanzima ukuze kuthuthukiswe imboni esimeme esikhathini esizayo. Lokhu futhi kuyincazelo nomusa wentuthuko yezobuchwepheshe.
Uma unemibuzo noma ungathanda ukwazi okwengeziwe, sicela ungangabazi ukungithumelelaxhumana nathi.
