Idatha ibonisa ukuthi ezinyangeni ezine zokuqala zalo nyaka, ukuthunyelwa kwe-iron phosphate ne-iron phosphate kuye kwanda uma kuqhathaniswa nesikhathi esifanayo ngonyaka odlule. Phakathi kwazo, umthamo wokuthunyelwa wamabhethri e-lithium iron phosphate ngu-2.6Gwh, futhi umthamo wokuthunyelwa wamabhethri we-ternary lithium uphezulu njengo-771.51MWh.

Ngaphezu kwalokho, izinga lokungena kwezinto ezisetshenziswayo ze-ternary zezimoto ezikhethekile ngo-2015 lalingama-61%, futhi isidingo safinyelela ku-1.1GWh. Ngo-2016, izinga lokungena lizofinyelela ku-65%, futhi isidingo sizoba ngu-2.9Gwh; ngo-2020, izinga lokungena lizofinyelela ku-80%, futhi isidingo semakethe sizoba ngu-14.0Gwh.

Kuyabonakala ukuthi izinto ze-ternary kanye ne-lithium iron phosphate kancane kancane zithatha indawo evamile ekusetshenzisweni kwezimoto ezihlanzekile zikagesi, futhi ingxenye yezinto ezisetshenziswayo izoba nkulu futhi ibe nkulu. Kodwa-ke, umzila wezobuchwepheshe izimoto ze-logistics zikagesi ezihlanzekile ezizowuthatha esikhathini esizayo awuxhomekile kuphela kubuchwepheshe kanye nekhwalithi yamandla amabhethri e-lithium, kodwa futhi ekufuneni kwemakethe nezindlela zokuphatha.

Okokuqala, kungani izinto ezintathu zihamba phambili ezimotweni ezisebenza ngogesi?

E-China, phakathi kwezimoto ezihlanzekile zikagesi ze-logistics, ubuchwepheshe bebhethri ye-lithium iyindlela esetshenziswa kakhulu, elandelwa amabhethri e-lithium iron phosphate. Yiqiniso, kumzila ofanayo wezobuchwepheshe, imingcele yamandla amabhethri e-lithium athuthukiswe abakhiqizi abahlukahlukene awafani. Isibonelo, i-Tesla ne-LG zisebenzisa izinto ze-ternary futhi zinemingcele ehlukene ngokwekhwalithi yebhethri, ububanzi bebhethri, impilo yomjikelezo, kanye nokuminyana kwamandla wephakethe lebhethri. Futhi amanye amapharamitha ashintsha njalo ngokuthuthukiswa okuqhubekayo kobuchwepheshe. Amapharamitha amaningi angamanani aphelele.

Lapha siqhathanisa izinzuzo nezingozi zezinto ezihlukahlukene zamandla e-lithium yebhethri ye-cathode ukuze siphendule umbuzo wokuthi kungani lezi zinto ezintathu zihamba phambili ezimotweni ze-logistics.

Ukuhlaziywa okujulile kwezizathu eziyisithupha zokuthi kungani amabhethri amakhulu amathathu ehlala emakethe evamile yezimoto ezisebenza ngogesi ezihlanzekile.

Ukuhlaziywa okujulile kwezizathu eziyisithupha zokuthi kungani amabhethri amakhulu amathathu ehlala emakethe evamile yezimoto ezisebenza ngogesi ezihlanzekile.

Okokuqala, kungabonakala emfanekisweni ukuthi noma ngabe ukuphepha kwe-ternary material akuphakeme, izinkampani eziningi zezimoto ze-logistics zizocubungula ngokucophelela, noma zizosebenzisa umzila we-ternary lithium webhethri, onobubanzi obukhulu bokuhamba, umthamo othize omkhulu. , impilo ende yesevisi, njll. inzuzo.

Okwesibili, ibanga lemayela lezimoto ezisebenza ngogesi ezihlanzekile lithinta izimo zokusebenza nokusebenza kahle kokuhlelwa kwezimoto. Ezimotweni ezihlanzekile zokuthutha zikagesi, okubalulekile ukusatshalaliswa kwempahla yokugcina, ezokuthutha zasemadolobheni, izindlu nezinye izimakethe. Kudingeka ukuqinisekisa ukuthi umsebenzi wokuthutha uqedwa phakathi nosuku olulodwa, ikakhulukazi phakathi namahora aphakeme njenge-Double Eleven, kanye nohambo olukhudlwana. Izinga lobubanzi lincike enanini lamabhethri nokumataniswa kwesistimu yokunikeza amandla.

Okwesithathu, okwamanje, uxhaso lukahulumeni luyahoxiswa, futhi imixhaso yomhlaba ilokhu yehla njalo. Ezindaweni eziningi, uxhaso lungaphansi kwama-yuan angama-400 ngehora le-kilowatt. Isibonelo, e-Jiangsu nase-Hangzhou, abanye opharetha bezimoto ezisebenza ngogesi bathe uxhaso oluphansi kangako , Ayikwazi ukudlala. Ezinkampanini zezimoto, kunengqondo ukufuna umzila wezobuchwepheshe ongabizi kakhulu. Izindleko zamabhethri e-lithium ezimoto ziphezulu kakhulu. Njengamanje, uxhaso ezindaweni eziningi luthuthukisiwe yinkampani, futhi ubuchwepheshe bokukhiqiza izimoto abuphakeme njengezinye izimoto. Izindleko zebhethri ye-lithium ye-ternary ziphansi kunebhethri ye-lithium iron phosphate, futhi izidingo zobuchwepheshe aziphezulu njengebhethri ye-lithium iron phosphate. Lokhu kusindisa kakhulu izinsiza zomphakathi kanye nezindleko zokukhiqiza. Okwesine, enye yezithende ezinkulu ze-Achilles ze-lithium iron phosphate ukusebenza kwayo okuphansi kwezinga lokushisa eliphansi, ngisho noma i-nano yayo ne-carbon coatings ayixazululi le nkinga. Ucwaningo luye lwabonisa ukuthi ibhethri elinomthamo we-3500mAh, uma lisebenza ku–10 ° C, ngemva kwemijikelezo engaphansi kwe-100 yokushaja, amandla ayo azobola ngokushesha aze afike ku-500mAh futhi ngokuyisisekelo alahliwe. Izinto ze-ternary zinokusebenza okuhle kwezinga lokushisa eliphansi, futhi ukuncishiswa kwanyanga zonke kungu-1 kuya ku-2%. Emazingeni okushisa aphansi, izinga layo lokwehla aliphezulu njenge-lithium iron phosphate.

Okwesihlanu, izinto ze-terpolymer zithatha izinto ezijwayelekile, ikakhulukazi ngenxa yethonya lezinkampani zezimoto zakwamanye amazwe. Iningi lezimoto zamandla amasha ezinkampani zezimoto zakwamanye amazwe zisebenzisa amabhethri e-ternary lithium, iningi lawo angamaseli ayi-18650. Kungabonakala futhi emaqenjini angama-286 ezimemezelo zezimoto ezintsha ukuthi iningi lezimoto ezihlanzekile zikagesi zisebenzisa amabhethri e-lithium angu-18650. I-voltage yesigaba esisodwa ngokuvamile ingu-3.6V noma i-3.7V; I-voltage encane yokunqamula ukukhishwa ngokuvamile i-2.5-2.75V. Umthamo ojwayelekile ngu-1200 ~ 3300mAh. 18650 ibhethri, kodwa ukungaguquguquki kuhle kakhulu; ibhethri eyisitakiki lingenziwa libe likhulu (20Ah kuya ku-60Ah), elinganciphisa inani lamabhethri, kodwa ukuvumelana kubi. Ngokuphambene, kulesi sigaba, kunzima kubahlinzeki bebhethri ukutshala amandla amaningi kanye nezinsiza ukuze kuthuthukiswe inqubo yokukhiqiza amabhethri astakiwe.

(2) Umumo nosayizi, ngenxa yokuthi izinhlobo ezintathu eziyinhloko zihlukene, kunomehluko, nobukhulu bohlobo olufanayo nabo buhlukile. Kunezinhlobo ezintathu zamabhethri e-ternary, eyodwa ibhethri yephakethe elithambile, njenge-A123, i-Vientiane, ne-polyfluorine. Elinye ibhethri eliyicylindrical, njengelikaTesla. Kukhona namabhethri angamagobolondo aqinile, afana ne-BYD ne-Samsung. Phakathi kwamafomu amathathu, izindleko zokukhiqiza amagobolondo aqinile ziphakeme, kulandelwa izikhwama ezithambile, futhi ekugcineni amasilinda. Omunye umbono uwukuthi ukuphepha kwesikhwama esithambile kuphakeme kunesilinda, futhi isakhiwo se-cylinder senza kube nzima ukuxazulula ngokuphelele inkinga yokuphepha. Okwamanje, ubuchwepheshe bokupakisha obuthambile bebhethri be-ternary busetshenzisiwe ezimotweni zezwe lami. Kodwa-ke, izidingo zobuchwepheshe zokupakisha okuguquguqukayo ziphakeme kakhulu, ikakhulukazi kubuchwepheshe bokupakisha. Ukungapakishwa kahle kuzodala izinkinga ezifana nokubhodla nokuvuza, futhi kudale izingozi zokuphepha. Ngamanye amazwi, ukusetshenziswa kwamabhethri e-ternary kusekelwe kumagobolondo ensimbi ayizikwele. Igobolondo lensimbi eliyisikwele linezinzuzo zokuma, ukuqoqa okulula, namandla athile aphezulu. Okubi futhi ukuthi umphumela wokukhipha ukushisa mubi.

3. Isakhiwo sebhethri ye-lithium yamandla

Ukuhlelwa kwebhethri ye-lithium yamandla kufanele kuhlelwe ngokuvumelana ne-chassis yemoto ehlanzekile yezinto zikagesi, kucatshangelwa ukukhanya komzimba nezinye izici, ngokuvamile ku-trunk yemoto, ngokusho kwamamodeli ahlukahlukene kagesi ohlanzekile. imoto Logistics. Isibonelo, amaloli namaloli amancane ahlelwe ngendlela ehlukile. Kafushane: 1. Kuyadingeka ukucabangela indawo yokuhlela amandla amabhethri e-lithium. 2. Uyini umthwalo? Ukulayishwa kwemoto. 4 ibhalansi. Kumelwe kube nezidingo ezithile zokusebenza zokulahla ukushisa. Ukwanelisa ubuncane bokuvunyelwa komhlaba, i-engeli yokudlula eyi-longitudinal nezinye izidingo zokudlula. Hlangana nesidingo esiqhubekayo sokusebenzisana namakhompyutha abantu. Kufanele ihambisane nemithetho kazwelonke yokushayisana. Inezinga elithile lezidingo zokuvala uphawu. Qinisekisa isidingo sikagesi onamandla amakhulu.

Ngaphezu kwalokho, ukuhlelwa kwebhethri ye-lithium yamandla kufanele futhi kucabangele ukuphepha komshayeli. Uma ihlelwe ngaphansi kwesihlalo, uma ibhethri livutha umlilo, isisulu sakamuva umshayeli. Uma uhlobisa phansi kwenqola, into yokuqala eletha inhlekelele yimpahla, futhi umshayeli unethuba eliphakeme lokubaleka.
