Isingeniso:
Njengamanje, kunenkinga evamile emotweni entsha yamandla kanyeibhethri ye-lithiumizimakethe zokugcina amandla, futhi lokho ukwesaba amakhaza. Ngaphandle kwesizathu esithile ngaphandle kwezindawo ezisezingeni eliphansi lokushisa, ukusebenza kwamabhethri e-lithium kuncishiswa kakhulu, kubonisa ukulahlekelwa okukhulu kwamandla namandla, ubunzima bokushaja, njll., noma ngisho nokwehluleka ukusebenza kahle.
Lapho kukhona amaphuzu ezinhlungu, kukhona namathuba amakhulu okuthuthukiswa. Ibhethri le-Xingdong Lithium Battery eliyingqayizivele elisezingeni eliphansi lenzelwe "ukubanda". Ngo-Agasti 8, esithangamini esithi "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 anamandla aphansi aneshaja ephezulu kanye nokusebenza kahle kokukhipha okungaphezulu kuka-97%, okwenza amabhethri e-iron phosphate aphansi aqinisekisa ukuthi amabhethri e-lithium aphansi kanye nezinga lokushisa eliphansi. amabhethri e-lithium iron phosphate nawo angasebenza ngokuzinza nangempumelelo ngaphansi kwezimo zezulu ezibandayo.
Indlela yokunqoba izinga lokushisa eliphansi lebhethri ye-lithium?
Ngaphansi kwezimo zokushisa eziphansi, izinga lokusabela kwamakhemikhali ngaphakathi kwebhethri liyancipha futhi isivinini sokunyakaza kwama-ion ku-electrolyte siyehla, okuthintaibhethri ye-lithiumukushaja nokukhipha ukusebenza kahle. Ngaphezu kwalokho, amazinga okushisa aphansi angase futhi abangele izinguquko esakhiweni esibalulekile ngaphakathi kwebhethri, ngaleyo ndlela kuthinte ukusebenza nempilo yebhethri.” U-Li Jia, umongameli webhizinisi lamazwe ngamazwe le-Xingdong Lithium Battery, uthe ukuze kuxazululwe inkinga yokusebenza kwamabhethri aphansi, ukhiye uwukwakha izinto ezikwazi ukumelana nezinga lokushisa eliphansi.
Kusukela ezintweni zokwakha nezinye izici, Ibhethri ye-Xingdong Lithium inqobe ubunzima futhi yathuthukisa ngempumelelo inombolo yobuchwepheshe obunelungelo lobunikazi. Iphinde yakhiqiza ngempumelelo izinga lokushisa eli-4 eliphansiamabhethri e-lithiumengashajwa futhi ikhishwe ezindaweni ezinezinga lokushisa eliphansi elingu -20℃, -25℃, -30℃, kanye -35℃, nebanga lomthamo elingu-206Ah kuya ku-314Ah, kanye nekhono elihambisanayo lokushaja nokukhipha okukhulu kuno-97%, 95%, 95%, okuhola imboni ngo-9, kanye no-9% ngokulandelana.
Uma sibhekisisa imfihlo, sizothola ukuthi inhlanganisela yegolide ye-Xingdong lithium battery "4+N" idlale indima ebalulekile. I-4 ibhekisela kubuchwepheshe obune obuyisisekelo, futhi i-N ibhekisela kubuchwepheshe obunamalungelo obunikazi obuningi obusetshenziswa ngokuhlangene:
1. Ngokuhlanganisa i-carbon nanotubes ne-graphene, iibhethri ye-lithiumI-impedance iyancipha kakhulu, ukumelana kwangaphakathi kungu-≤0.25mΩ, ukusebenza kwezinga kuthuthukiswa kakhulu, futhi kungasekela ukukhishwa kwe-15C ngokushesha;
2. Ubuchwepheshe bokumboza i-diaphragm obunelungelo lobunikazi bamukelwa ukwenza isigxobo sesigxobo siboshwe kakhulu ngesikhathi sokusebenza, ukuthuthukisa ngempumelelo ukuphepha kwebhethri nokusebenza komjikelezo;
3. I-electrolyte yejeli ye-in-situ enelungelo lobunikazi iyamukelwa, futhi isiqalisi kanye ne-coagulant ehambisana nebhethri ye-lithium iron phosphate yengezwa ukwenza ibhethri imelane kakhulu nezinga lokushisa eliphansi, futhi izinga lokushisa lokusebenza kwebhethri lingafinyelela -35℃～60℃;
4. Inqubo yokunqwabelanisa iyamukelwa, uma kuqhathaniswa nenqubo yokugoqa yendabuko, ukumelana kwangaphakathi kuncishiswa ngo-30%, ngokuzinza okungcono kwesakhiwo, ukuphepha okuphezulu, impilo yomjikelezo omude, kanye nokushuba kwamandla ≥180Wh/kg;
5. Ngamalungelo obunikazi bokusungulwa kwe-43, uhlelo lwe-lithium iron phosphate luyamukelwa, luhlanganiswe nezinqubo eziyingqayizivele, futhi ukukhiqizwa okuzenzakalelayo ngokugcwele kanye nemigqa yokukhiqiza enembile isetshenziselwa ukuqinisekisa ukuhambisana okuphezulu kwamaseli ebhethri, futhi kuzokhuthaza ukuthuthukiswa okuqhubekayo nokuphindaphinda kwemikhiqizo.
Umthelela embonini yebhethri ye-lithium
Ezingeni lobuchwepheshe, amabhethri amaningi emakethe okwamanje angasebenza ezingeni lokushisa -20℃～60℃, kuyilapho izinga lokushisa eliphansi le-Xingdong Lithium Batteryibhethri ye-lithiumingasebenza ebangeni lokushisa elingu -35℃～60℃, elibophezelekile ukuthi ligqugquzele ukuthuthukiswa nokuqanjwa kabusha kobuchwepheshe bebhethri obusezingeni eliphansi futhi lihole;
Ezingeni lemboni, i-Xingdong Lithium Battery ibhekana nenkinga yamabhethri asezingeni eliphansi futhi yethula imikhiqizo ehamba phambili embonini. Phakathi kwazo, izinga lokushisa eliphansi -35 ℃ibhethri ye-lithiuminezindleko zokushaja kanye nokukhipha amandla okungaphezu kwama-90%, okungagcini nje ngokwenza inzuzo ehlukene, kodwa futhi kusho ukuthi imboni izozuza ngempela amalungelo alinganayo amandla enyakatho naseningizimu, ibe enye ingqophamlando ekuthuthukisweni kobuchwepheshe bebhethri;
Ezingeni lemakethe, enye yezinselelo okwamanje ebhekene nempahla yezempi yokuphakama okuphezulu ukuthi njengoba ukuphakama kwendiza kukhuphuka, indawo yokushisa ephansi endaweni ephakeme ingase ibangele ukusebenza kwebhethri kwehle; izindawo ezinezinga eliphansi lokushisa ebusika njenge-Inner Mongolia ne-Xinjiang zisebenza kanzima ukuze zikhuthaze ukwakhiwa kwezimayini eziluhlaza; Izimakethe zaphesheya njenge-Europe ne-United States zinezimo zezulu ezinzima zasebusika, amandla abuthaka okuxhumana kwegridi, namanani aphezulu kagesi. Izakhamuzi zidinga ukufanisa amasistimu okugcina amandla okushisa aphansi ukuze kuqinisekiswe ukusetshenziswa kukagesi okuzinzile ebusika...
Isidingo semakethe sokusebenza okuphezulu kwezinga lokushisa eliphansiamabhethri e-lithiumkuyaphuthuma, futhi amabhethri e-Xingdong Lithium anezinga lokushisa eliphansi awakwazi nje ukuhlangabezana ngokugcwele nezidingo zezimo zokusetshenziswa ezishiwo ngenhla, kodwa futhi akhiqizwa ngobuningi futhi angasetshenziswa ngokushesha.
Ezingeni lokwehliswa kwezindleko eziluhlaza, kuphela ngokushayela ukusungula izinto ezintsha zobuchwepheshe kanye nokuqanjwa kabusha kwezimboni lapho singasheshisa khona ukuthuthukiswa kokukhiqiza kwekhwalithi entsha futhi sifeze kangcono imigomo "yekhabhoni ekabili". Amabhethri e-Xingdong Lithium anezinga lokushisa eliphansi aphula imikhawulo yendawo futhi angasetshenziswa kabanzi ekufakeni ugesi emishinini yobunjiniyela esindayo, kanye nokugcinwa kwamandla/amandla ezindaweni ezinezinga lokushisa eliphansi emhlabeni jikelele.
Isiphetho
Sekukonke,izinkampani zebhethri ze-lithiumbebelokhu besabela ngenkuthalo ezinseleleni zemakethe, bethuthuka njalo futhi bebhodloza, futhi behlinzeka ngokuqhubekayo izixazululo zobuchwepheshe ezintsha nezingabizi kakhulu zabafuna ibhethri ye-lithium esebenza kahle kakhulu. Kusukela kumaphuzu obuhlungu bamakhasimende, basebenza kanzima ekuthuthukisweni okusimeme kwemboni esikhathini esizayo. Lokhu futhi kuyincazelo kanye nokukhangayo kwentuthuko yezobuchwepheshe.
