BYD is all replaced by three yuan batteries next year, how to do lithium iron phosphate?

Umbhali :Iflowpower-UMboneleli weSikhululo saMandla esiphathwayo

NgoDisemba 5, "Kunyaka ozayo, zonke iimoto zabakhweli kwi-BYD ziya kusebenzisa ibhetri ye-yuan ezintathu!" Khupha, vumela ibhetri yeyuan ezintathu. I-BYD ithathelwe indawo ibhetri yeeyuan ezintathu, sizame ukuba yivenkile yenkulungwane ezayo kaDisemba 5, i-BYD ibhengeze irekhodi yobudlelwane bomtyali-mali ifomu, iveze ulwazi oluthathu olubalulekileyo: 1 imveliso iyonke iya kufikelela 16GWH: Ukuya kuthi ga ekupheleni kwalo nyaka, BYD amandla lithium Isiphumo esipheleleyo seebhetri ze-ion siya kufikelela kwi-16GWH, apho i-10GWH ibhetri ye-lithium yentsimbi, i-6GWH ibhetri ye-ternary; I-2 eyandisiweyo ye-yuan yebhetri ye-yuan: i-BYD iya kwandisa i-factory yebhetri kunye ne-10GWH imveliso yebhetri ye-ternary eQinghai; 3 kunyaka ozayo, BYD Umkhweli yonke indawo ibhetri yuan ezintathu: I-BYD yathi iPHEV entsha yenkampani iye yatshintshwa ibhetri ye-yuan ezintathu, kwaye zonke iimoto zomkhweli zenkampani ziya kusetyenziswa kwiibhetri ezintathu zeeyuan. Ibhasi kunye ne-E6 iya kuqhubeka nokusebenzisa i-lithium iron phosphate ion iibhetri.

Ngaphambili, nge-29 ka-Agasti, i-BYD ibhengeze inkampani yendibaniselwano yokusekwa kwebhetri ye-lithium-ion ye-yuan emithathu yeprojekthi ye-precursor yezinto ezilungileyo kwi-BYD. Kwimeko "engabonakaliyo" kwiinkampani zeemoto zasekhaya kunye nezangaphandle, ukhetho lwe-BYD alukho inyathelo lobulumko. Ukongeza kwi-lithium iron phosphate ukuya kwi-yuan ezintathu, i-BYD ibhengezwe ngoNovemba ukubhengeza ulwakhiwo lohlengahlengiso, oluzimisele ukuqhubeka nokudibanisa amandla amatsha, kwaye sizame ukuba yivenkile yenkulungwane ezayo.

Kwisikhumbuzo se-23rd ye-18 kaNovemba, i-Time Value BYD yasekwa. Kwi "uhambo olutsha, ikamva elitsha", uWang Chuanfu ubhengeze iinjongo zophuhliso lwexesha elizayo kunye nokucinga kohlaziyo lwe-BYD, ufuna ukwakha i-BYD kwiminyaka elikhulu. Ivenkile endala, malunga no-2025, i-BYD kufuneka ifezekise isikali seetriliyoni zeeyuan ngokupheleleyo.

Undoqo wentlanganiso unala manqaku mabini alandelayo: I-1 yamandla avulekileyo e-lithium-ion ibhetri kunye nezinye iinkonzo. Ukuqina kokhuphiswano loshishino lwamandla amatsha, ukunyanzela nayiphi na inkampani ukuba ihambisane nemfuno yemarike, kwaye ngaloo ndlela "inkqubo yokubonelela ngemveliso evaliweyo" kwi-BYD ibonakala ingakhululeki, kwaye i-Ningde Times, eya kudweliswa iya kuba. BYD. Olona khuphiswano lunamandla lwebhetri yi-BYD ngokuthe ngcembe isiya kwindlela yokuvula, yomeleza intsebenziswano nezinye iinkampani.

Ngokwezibalo, kwii-20 eziphezulu ezifakwe kumatshini kwi-20 ephezulu yenkampani yebhetri ngo-Oktobha kulo nyaka, i-Ningde Times (CATL) ikhokela i-1083.4mWh, isabelo semarike yi-32.32%; Inqanaba le-BYD ukusuka kwi-490.

I-4MWH, i-14.63% yesabelo semarike, kungekhona i-Ningde Times Isiqingatha sesiqingatha. Ukuze uphule i-bottleneck yophuhliso, i-BYD ayilungiseleli kuphela ukwahlula ishishini lebhetri, ezinye iindawo, isofthiwe yemoto, i-molds kunye namanye amasebe, iya kusebenza ngokuzimeleyo kwikamva.

Kutshanje, i-BYD Holdings Subsidiary BYD Automotive Industry Co., Ltd. icebise inkampani ukuba iseke ngokudibeneyo iShenzhen Folia Auto Parts Co.

, Ltd., ukuvelisa isihlalo semoto, njl. Ukongeza, ngoSeptemba 21, kulo nyaka, uWang Chuanfu uthe kwitafile ejikelezayo yeendaba eyayibanjelwe eShenzhen, "i-BYD iqwalasela ukubonelela iibhetri kwabanye abavelisi beemoto, kwaye kulindeleke ukuba ivakalise. isivumelwano sokuqala phambi kokuphela konyaka.

"I-2 iba yivenkile yeminyaka eyikhulu ezayo. U-Wang Chuanfu uthe kwintlanganiso yesigqeba senkampani, "i-BYD ayiyona inkampani yebhetri, kungekhona nje inkampani yemoto", kodwa isikhundla esitsha "isisombululo samandla amatsha ngokubanzi kwindalo. Ngokutsho kwesicwangciso, i-BYD iya kwakha isakhiwo sombutho we "Business Group + Division" ngokuhambelana necandelo loshishino, ukuhlakulela iindawo ezintsha zokunyuka, kuquka iimoto zabahambi, iimoto zorhwebo, amaqela oshishino lwe-elektroniki, amaqela oshishino ebhetri, amafu amafu I-9 amashishini zizibane ze-BYD, i-BYD mold, i-BYD imoto yezixhobo, i-injini ye-BYD, i-BYD imoto ye-elektroniki, i-motor ye-BYD, i-BYD, i-BYD Auto Equipment, i-BYD Software Research Institute.

Kwaye bonke abasebenzi ukugaya iqela inxaxheba kwisakhiwo uphawu, walala uphuculo elungileyo uhlaselo uphawu, kwaye idluliselwe ngokucacileyo ukunikezelwa BYD kwitsheyini entsha amandla full industry. Umgaqo-nkqubo + weMakethi i-Double Drive Three-Dynamic Lithium Ion Battery Industry izinzile kwimarike ngobushushu bayo obuphantsi, ukuxinana kwamandla aphezulu, ukusebenza kakuhle kwentlawulo, ubomi obuhle bokujikeleza. Kwaye ngoku imigaqo-nkqubo okanye isikhokelo, okanye imveliso yenkampani iye yaguqulelwa kwiiyuan ezintathu.

Ngokutsho kwesicwangciso sikazwelonke, i-2020, ubuninzi bamandla ombane we-lithium-ion ibhetri 350WH / kg, i-2025 ekujoliswe kuyo yi-400Wh / kg, i-2030 ekujoliswe kuyo yi-500Wh / kg. Ukususela kulo nyaka, njengoko umgaqo-nkqubo ukhutshwa kwibhetri ye-yuan ezintathu, kwaye ibhetri ye-yuan ezintathu ilindeleke kakhulu ngenxa yobuninzi bamandla, iingenelo zokuxinana kwamandla aphezulu, kunye nokunyuka kwendawo kuphezulu. Kuxelwe ukuba owona mndilili wokuxinana kwamandla ebhetri ye-ternary yi-180 ~ 190Wh / kg, eyi-20% ukuya kwi-50% xa kuthelekiswa ne-ferrite.

Kodwa akuhoywa ukuba ukhuseleko lwebhetri ye-yuan ezintathu alwanelanga. Ukongeza kutyekelo lokuxinana kwamandla aphezulu ebhetri ye-lithium-ion eguquguqukayo, ukusebenza kwemarike yalo nyaka kwenza ibhetri yeeyuan ezintathu. Ngokophando lwendawo yokuqala, imveliso yebhetri ye-lithium-ion yelizwe lam yi-31GWh kwiikota ezintathu zokuqala zika-2017.

apho i-NCM (i-nickel-cobalt manganese) ithatha i-49%, i-LZ (i-lithium phosphate) yenza i-40%, i-Lithium manganeti ilinganisela. 8%. Kufuneka kuqatshelwe ukuba ibhetri ye-ternary ibhekisela kwibhetri ye-lithium ion ebhekisela kwizinto ezintle usebenzisa i-lithium-cobalt-manganese acid okanye i-nickel-cobalt olycineate.

Okwangoku, ukusetyenziswa okubalulekileyo kweebhetri ze-ternary yi-NCM333 kunye ne-NCM523, kwaye i-NCM622 ingene kwinkqubo yokubonelela ngeenkampani ezithile. I-NCM811 ikwinqanaba lophuhliso. Ngokwezibalo, i-NCM ye-ternary (nickel-cobalt manganese) okwangoku i-333, 523, 622, 811 imodeli ezine.

Ukuphakama komxholo we-nickel wezinto ezibalulekileyo ezisebenzayo, umthamo obaluleke ngakumbi webhetri: ibhetri eqinile ifana nengcuka efana nale yangoku Kwinqanaba lokujonga, ingxaki enkulu yokunyanzeliswa kwenkqubo ye-yuan ezintathu kukhuseleko. Nje ukuba ingxaki yokhuseleko isonjululwe, njengoko eyona nto ikhulileyo ilungileyo yoxinzelelo lwamandla iyinto yendalo kwaye imarike yangoku, inkqubo yeendlela ezintathu iya kuba kwithuba elide kakhulu ixesha elide. Ukongamela emsebenzini.

Kwintsebenzo yemarike edibeneyo, i-cobalt ephezulu ye-nickel ephantsi iya kuba yikhokelo yophuhliso lwebhetri ye-yuan emithathu ezayo. Nangona kunjalo, i-lithium iron phosphate inokhuseleko oluphezulu, izibonelelo zezinto ezibonakalayo ezityebileyo, kwaye iindleko zeendleko zinzima ukuhambelana, kwaye ngexesha elifutshane, ukutshintshwa kwe-yuan ezintathu kwi-lithium iron phosphate ayiboniswa ngexesha elifutshane. kwexesha, kunye ne-iron phosphate Lithium nayo inemarike enkulu ye-post-enokwenzeka kwindawo yokugcina amandla. Nangona ezi zimbini zinenzuzo, iintsilelo kusekho ixesha, ngelixa ekusombululeni ezi ngxaki, indlela entsha ye-lithium-ion ye-teknoloji yebhetri iya kuzalwa emoyeni, kwaye ibhetri ye-lithium-ion yelizwe eliqinileyo kulindeleke ukuba ibe yilandelayo. isizukulwana.

Amandla oxinaniso lwamandla aphezulu kunye nogcino lwamandla ebhetri iteknoloji iye yaba yimvumelwano yezemfundo kunye neshishini. Kwaye iToyota, i-TDK yaseJapan yeBattery Factory, i-Samsung SDI, i-LG Chemical, i-ATL, njl., ngokunyanzeliswa, isimo esiqinileyo, ukuqala ukusuka kulo nyaka uzayo, ibhetri yelizwe eliqinileyo iya kusetyenziswa kwidijithali kunye namanye amasimi, i-2019-2020, iya kubumba ngokuthe ngcembe. isikali.
