Kodwa-ke, ukuntuleka kwe-olivine crystal structure ye-lithium iron phosphate positive electrode material, njenge-conductivity ephansi kagesi, i-coefficient encane ye-lithium ion diffusion, njll.

, okubangela ukuminyana kwamandla okuphansi, ukumelana nezinga lokushisa eliphansi nokusebenza kwephutha, njll. izokhawulelwa endaweni yesicelo. Thuthukisa ukungalungi kwayo Amakilasi angaphezulu abalulekile ashintshiwe, ukuguqulwa kwesigaba esibalulekile se-doping, njll.

Eminyakeni yamuva nje, imakethe yebhethri ye-lithium-ion enikwe amandla yezwe lami ibe nokuqhuma okukhulu, ubuchwepheshe bebhethri buwukuncintisana kwayo okuyisisekelo. Njengamanje, amabhethri e-lithium-ion abalulekile ahlanganisa amabhethri e-ion e-lithium iron phosphate, amabhethri e-ion e-lithium-manganese nebhethri ye-ion enezinhlangothi ezintathu. Ithebula lesi-2 liqhathanisa ukusebenza kwezinhlobo ezahlukene zamabhethri e-lithium-ion, lapho i-DOD iwukujula kokujula (Ukukhipha).

Ibhethri ye-Lithium iron phosphate ion isekela imboni yebhethri ye-lithium-ion yezwe lami ingxenye ye-Wanjiang Mountain, enezinzuzo ezinkulu kumabhethri ahlukahlukene: ibhethri ye-lithium iron phosphate ion yinde uma kuqhathaniswa, ikhiqiza ukushisa okuphansi, ukuzinza okuhle okushisayo, kanye namabhethri e-lithium iron phosphate Ion nawo anokuphepha okuhle kwemvelo. Ibhethri ye-lithium phosphate ion isetshenziswa ezimotweni zabagibeli zikagesi ezinenani eliphansi nokusebenza okuzinzile, futhi isabelo semakethe sibonisa isimo esikhuphukayo. Izinto ezibonakalayo zinezinzuzo zokuphepha okuhle, impilo yomjikelezo omude, izindleko eziphansi, njll.

, into eyinhloko ye-electrode eqondile. Ngokufaka i-nanochemical kanye ne-surface carbon cladding, ukusebenza kokukhishwa kwamandla amakhulu kufinyelelwa, futhi isampula ehlanganiswe nekhabhoni yenziwa kahle ngaphandle kokuzikhethela, futhi izwe lami lizuze ukukhiqizwa kwesikali esikhulu kunazo zonke emhlabeni. I-2, i-Ningde Times ne-BYD iholele indlela ye-CTP, iphinde inciphise izindleko zikaSihlalo we-BYD u-Wang Chuanfu, lapho iqhaza emotweni kagesi, i-BYD isungule isizukulwane esisha sebhethri ye-phosphate ion "ibhethri ye-blade", leli bhethri kulindeleke ukuthi likhiqize kulo nyaka "Ibhethri ye-Blade" iye yanda ngo-50% ngaphezu kwebhethri yendabuko yensimbi, impilo ende yokuphepha, impilo ende yokuphepha, impilo ende yokuphepha, impilo ende yokuphepha, ukuphepha kwebhethri, ukuphila okude, ukuphepha kwebhethri, ukuphila okude, ukuphila okude, ukuphepha kwebhethri. izigidi zamakhilomitha, ukuminyana kwamandla kungafinyelela ku-180Wh / kg, uma kuqhathaniswa nangaphambili Ukwanda cishe ku-9%, okungenabuthakathaka obubuthakathaka kunebhethri ye-ternary lithium ion ye-NCM811, futhi ingaxazulula inkinga nge-low density yamandla webhethri ye-ion ye-lithium iron phosphate.

Leli bhethri lizofakwa ku-BYD "Han" kwi-New Car, okulindeleke ukuthi ifakwe ohlwini ngoJuni nonyaka. Liyini ibhethri le-blade? Eqinisweni, kuyindlela ende yebhethri (igobolondo le-aluminium elibalulekile elimise umunwe). Thuthukisa futhi ukusebenza kahle kokuhlanganisa iphakethe lebhethri ngokwandisa ubude bebhethri (ubude obuphelele bulingana nobubanzi bephakethe lebhethri).

Akulona ibhethri elingusayizi othize, kodwa uchungechunge lwamaqoqo osayizi abahlukene lungakhiwa ngokusekelwe ezidingweni ezihlukene. Ngokwencazelo yelungelo lobunikazi le-BYD, "ibhethri ye-blade" yigama lebhethri le-ion ye-phosphate ion lesizukulwane esisha se-BYD. Kuyi-BYD ukuthuthukisa iminyaka eminingi "yebhethri ye-ion ye-superphosphate".

Ibhethri yeblade empeleni ubude be-BYD bukhulu noma bulingana no-600mm ngaphansi noma obulingana no-2500 mm, obuhlelwa ngochungechunge "lweblade" efakwe ephaketheni lebhethri. Ukugxila kokuthuthukiswa "kwebhethri ye-blade" yiphakethe lebhethri (okungukuthi, ubuchwepheshe be-CTP), okuyiphakethe lebhethri (okungukuthi, ubuchwepheshe be-CTP), elihlanganiswe ngokuqondile namaphakethe ebhethri (okungukuthi, ubuchwepheshe be-CTP). Iphekhi yebhethri ye-blade ithuthukiswa ngokuthuthukisa ukwakheka kwephakethe lebhethri, ngaleyo ndlela kwandise ukusebenza kahle ngemva kwephakethe lebhethri, kodwa alinawo umthelela omkhulu ekumineni kwamandla e-monomer.

Ngokuchaza ukuhlelwa kwebhethri kanye nosayizi weseli, iphakethe lebhethri lingahlelwa kuphakethe lebhethri. Ibhethri le-monomer ngqo kundlu yephakethe lebhethri ithuthukiswa uhlaka lwemojuli. Ngakolunye uhlangothi, kulula ukuqeda ukushisa ngezindlu zebhethri noma ezinye izingxenye zokushisa ukushisa, ngakolunye uhlangothi, zingahlela ama-oda amaningi endaweni ephumelelayo.

Ibhethri lomzimba, lingakhuphula kakhulu ukusetshenziswa kwevolumu, futhi inqubo yokukhiqiza yephakethe yebhethri yenziwe lula, ukuhlangana okuyinkimbinkimbi kweyunithi yeyunithi kuyehliswa, izindleko zokukhiqiza zehliswe, ukuze iphakethe lebhethri nesisindo salo lonke iphakethe lebhethri kuncishiswe, futhi iphakethe lebhethri liyabonakala. Engasindi. Njengoba isidingo somsebenzisi sempilo yebhethri yemoto kagesi sikhula kancane kancane, esimeni esilinganiselwe, iphakethe lebhethri le-blade lingathuthukiswa, ngakolunye uhlangothi, izinga lokusebenzisa indawo yephakethe lebhethri le-lithium-ion, ukuminyana kwamandla amasha, kanye nezinye izici zingaqinisekisa ukuthi ibhethri le-monomer linendawo enkulu ngokwanele yokukhipha ukushisa, engakwazi ukuhambisana nokuminyana okuphezulu ngaphandle.

Ngokwencazelo yochwepheshe abangochwepheshe, ngenxa yezinto ezithile, njengezingxenye ze-peripheral zizohlala endaweni yangaphakathi yebhethri, okuhlanganisa indawo engaphansi evimbela ukuhlasela, isistimu yokupholisa uketshezi, izinto zokufakelwa, ukuvikela ukufakwa kwe-insulation, izesekeli zokuphepha kokushisa, irowu Iphaseji yomoya, imojula yokusabalalisa amandla kagesi aphezulu, njll., inani eliphakeme lokusetshenziswa kwendawo ngokuvamile licishe libe ngu-80%, noma isilinganiso esithile semakethe silingana no-50% njengesikhala esiphansi. 40%. Njengoba kukhonjisiwe esithombeni esingezansi, ngokuthuthukisa imodyuli, ukunciphisa ukusetshenziswa kwendawo kwengxenye yengxenye (ivolumu yevolumu yeseli kanye nesithombe sangemuva sephakethe lebhethri) kuthuthukiswa ngempumelelo, ukusetshenziswa kwesikhala kweSibonelo sokuQhathanisa 1 ngu-55%, kanye nokuqaliswa Izinga lokusebenzisa indawo leSibonelo 1-3% sasingu-260% / 57% ngokuhlonipha; izinga lokusebenzisa indawo leSibonelo sokuQhathanisa 2 lalingu-53%, kanti izinga lokusebenzisa indawo leSibonelo 4-5 lalingu-59% / 61%, ngokulandelana.

Amadigri ahlukene okuthuthukisa, kodwa kusekhona ibanga elithile ukusuka ekuphakameni kwesilinganiso sokusetshenziswa kwendawo. Ukusebenza kokukhipha ukushisa kumojuli yebhethri, i-BYD ilawulwa ngokusetha ipuleti elishisayo (phansi kwesokunxele Fig. 218) kanye nepuleti lokushintshanisa ukushisa ukuze kuqinisekiswe ukushiswa kokushisa kweyunithi yeseli, nokuqinisekisa ukuthi umehluko wezinga lokushisa phakathi kobuningi bamabhethri e-monomer awubi mkhulu kakhulu.

Ipuleti le-thermal conductive lingenziwa ngezinto ezinokusebenza okuhle kwe-thermal, njengethusi noma i-aluminium efana ne-thermal conductivity. Ipuleti lokushintsha ukushisa (ngezansi kwesokudla Fig. 219) ihlinzekwa ngesibandisi, futhi ukupholisa kwebhethri le-monomer kufinyelelwa ngesipholile, ukuze ibhethri le-monomer libe ezingeni lokushisa elifanele lokusebenza.

Njengoba ipuleti lokudlulisa ukushisa linikezwa ipuleti le-thermal conductive elinebhethri le-monomer, lapho kupholisa ibhethri le-monomer ngesipholisi, umehluko wezinga lokushisa phakathi kwamapuleti okushintshanisa ukushisa ungalinganiswa ngepuleti le-thermal conductive, ngaleyo ndlela kuvinjwe ubuningi bamabhethri e-monomer. Ukulawula umehluko wezinga lokushisa ngaphakathi kuka-1 ° C. Isibonelo Sokuqhathanisa 4 nebhethri le-monomer kuSibonelo 7-11, ukushajwa okusheshayo ku-2C, ukulinganisa ngesikhathi sokushaja okusheshayo, ukukhuphuka kwezinga lokushisa kwebhethri le-monomer.

Ingabonakala kudatha esethebulani. Kubhethri le-monomer enelungelo lobunikazi, ekushajweni okusheshayo kwezimo ezifanayo, ukukhuphuka kwezinga lokushisa kunamazinga ahlukene okunciphisa, okunomphumela ophakeme wokushabalalisa ukushisa, ngeke Lapho imojula yeseli ilayishwa kuphakethe lebhethri, ukukhuphuka kwezinga lokushisa kwephakethe lebhethri kunokuncipha kwamaphakethe ebhethri. Kukhona futhi insiza efanayo "njengebhethri ye-blade" kanye nobuchwepheshe be-CTP.

Ubuchwepheshe be-CTP (CELLTOPACK) ukuthola iqembu elingenabhethri, iphakethe lebhethri elihlanganisiwe eliqondile. Ngo-2019, i-Ningde Times yahola ekusebenziseni amaphakethe ebhethri angenawo ubuchwepheshe be-CTP. Kuboniswa ukuthi izinga lokusetshenziswa kwevolumu yamaphakethe ebhethri e-CTP lenyuke ngo-15% -20%, futhi inani lezingxenye lincishiswe ngo-40%.

Ukusebenza kahle kokukhiqiza kukhuphuke ngo-50%. Ngemuva kokutshala imali kuhlelo lokusebenza, kuzonciphisa kakhulu izindleko zokukhiqiza amandla ebhethri ye-lithium-ion. I-BYD ihlela ukuya ku-2020, ukuminyana kwayo kwe-phosphate monomer energy kuzofinyelela ku-180Wh / kg noma ngaphezulu, futhi ukuminyana kwamandla wesistimu nakho kuzokhuphuka ku-160Wh / kg noma ngaphezulu.

Ubuchwepheshe be-CTP be-Ningde Times buhlinzekwa ngephakethe lebhethri, elihlangabezana nephakethe lebhethri. Ilula, thuthukisa ukushuba kokuxhumeka kwephakethe lebhethri kuyo yonke imoto. Inzuzo yayo ibalulekile ukuba namaphuzu amabili: 1) Amaphakethe ebhethri e-CTP angasetshenziswa kumamodeli ahlukene ngoba ayikho imikhawulo yemojula evamile.

I-2), ukunciphisa izakhiwo zangaphakathi, amaphakethe ebhethri e-CTP angakhuphula ukusetshenziswa kwevolumu, ukuminyana kwamandla esistimu nakho akuqondile, umphumela wawo wokushisa ukushisa uphakeme kunephakethe lebhethri lemoduli encane yamanje. Kubuchwepheshe be-CTP, i-Ningde Times inaka ukukhululeka kwemojuli yebhethri, i-BYD ikhathazeke kakhulu ngokuthi amabhethri e-monomeric alayisha kanjani kanye nokusetshenziswa kwendawo. 3, ibhethri ye-blade kanye nendlela ye-CTP inganciphisa u-15%.

Sikhetha ibhethri ye-lithium-ion yobuchwepheshe obuphezulu be-Guoxuan njengento yethu yocwaningo. Izindleko zebhethri zizoba nereferensi ephezulu kumabhethri e-LFP.

8% no-30.4%, ngokulandelana. Ngakho-ke, ngokusho kwamasethi amabili wedatha angenhla, singabala izindleko zokukhiqiza zebhethri ye-LFP.

Ngo-2016, ingu-1.058 yuan / WH, futhi engxenyeni yokuqala ka-2019, ibe ngaphansi kuka-0.7 yuan / WH.

Kubalulekile ngoba izindleko zezinto ezingavuthiwe zehla zisuka ku-0.871 yuan / WH ngo-2016 zaya ku-0.574 yuan / WH engxenyeni yokuqala ka-2019, zehla ngokuphelele ngo-0.

3 Yuan / WH, uma kuqhathaniswa nama-34%. Mayelana nokuhlukaniswa, ezindlekweni eziphelele zokukhiqiza, izindleko zezinto zokusetshenziswa bezinzile kusukela ngo-2016, kuyilapho izindleko zamandla, izindleko zabasebenzi kanye nezindleko zokukhiqiza zibalelwa ku-6%. Siqhubekile nokuhlukanisa izindleko zezinto zokusetshenziswa, futhi sithole ukuthi ingxenye ye-positive kanye ne-diaphragm ezintweni ezingavuthiwe inkulu, cishe i-10%, i-electrode engalungile, i-electrolyte, i-foil yethusi, ikhava yegobolondo le-aluminium, izindleko ze-BMS, i-BMS.

Cishe ukusuka ku-7% kuya ku-8%, ibhokisi lebhethri kanye neqembu le-methyl akhawunti ngayinye cishe ngama-5%, i-Pack esele nezinye izindleko, ezibalela cishe u-30% wezindleko. Kungabonakala ukuthi izindleko zezinto ezingavuthiwe zingahlukaniswa ngamabhulokhi amathathu amakhulu ebhethri ye-LFP, enye yazo okuyizinto ezine ezinkulu zokusetshenziswa (i-electrode e-positive, i-electrode engalungile, i-diaphragm, i-electrolyte), isamba sezindleko zokubala cishe ama-35%, i-Pack ithatha u-30%, i-surplus 35% kwezinye izinto zokusetshenziswa nezingxenye. Ngolwazi olungenhla, sinikeza izilinganiso ezilandelayo zokulinganisa izindleko: 1) Ivolumu yebhethri ye-blade icishe ibe ngama-50% ngaphezu kokuminyana kwamandla.

Uma inani lokushaja lihlala njalo, ivolumu iyancipha ngaphezu kwengxenye eyodwa kwezintathu, ukuze ikhava yegobolondo le-aluminium iqhutshwe. Izindleko zephakethe, kucatshangwa ukuthi zehla ngo-33% 2) Amandla, okokwenziwa, izindleko zokukhiqiza, kanye nokwehla kwe-BMS ngenxa yokwenziwa ngcono kwezinqubo nokwehliswa kwezingxenye, kucatshangelwa ukuncishiswa okungama-20% 3) kuphinde kucabange ukuthi izinto ezingavuthiwe (okubandakanya i-electrode enhle, i-electrode engalungile, i-diaphragm, i-electrolyte, i-copper foil , i-Methyl, intengo yebhethri ingakwazi ukwehla ngamanani angu-20% we-LFP) 0.696 yuan / WH kuya ku-24.

3% ukuya ku-0.527 yuan / WH. 4) Ngokuqhubekayo kucatshangelwa umkhawulo wenzuzo enkulu yenkampani ingasetshenziswa ukuthola amanani angempela okuthengisa, njengoba kukhonjisiwe kuMfanekiso 35, ibhethri ye-blade kanye nendlela ye-CTP izohola kuphela ezimotweni zezentengiselwano, nakuba i-BYD yamemezela, indlela yebhethri ye-blade izosetshenziselwa ukuhweba e-Han Nokho, izimoto zezohwebo zisazoba yindlela yokusebenzisa.

Sikholelwa ukuthi i-BYD isetshenziselwa ukuthengisa emotweni yethu yabagibeli, okuwukugqekeza umqondo wemboni ojwayelekile: ubuchwepheshe obusha buvamise ukuthuthuka ezimotweni zentengiso, futhi izimoto zabagibeli zizoqapha kakhulu. I-BYD isebenzisa amabhethri e-blade emotweni yayo, ngokungangabazeki esejubaneni lokuphromotha imoto yabagibeli. Eqinisweni, ibhethri ye-blade kanye nendlela ye-CTP iyafana, futhi inhloso yokunciphisa izindleko, kuyilapho ibhethri le-monomer likhulu, futhi i-lithium iron phosphate ikhethwa.

Ngokusekelwe ngo-2019, kube nemishini eminingi yomugqa wokuqala ukusebenzisa indlela ye-CTP ukuze bathole ukuhlolwa, ngakho lobu buchwepheshe kulindeleke ukuthi busebenzise lobu buchwepheshe ngo-2020. Ngokuhambisana nokucatshangelwa okungenhla, sibala amamitha angu-10 noma ngaphezulu, izindleko zebhethri zincishiswa ngo-30%, futhi izindleko zebhethri ziyancipha zisuka ku-225,000 kuya ku-158,000. Uma lungekho uxhaso, isamba senzuzo singagcinwa.

Silindele ukuthi ibhethri le-2020 phosphate&39;s tamite lizothuthukiswa futhi ezimotweni zentengiso. Ngokombono wokutshalwa kwezimali, i-phosphite ekhuphuka nomfula ibekwe, kanye nokuthuthukiswa okuphansi kwenzuzo yebhizinisi lebhizinisi. Njengoba ukuphakama kwayo yonke i-lithium iron phosphate sekudlule iminyaka emithathu, ukugxila embonini kuphezulu.

Ochungechungeni lwezimboni, uma ufinyelela kubahlinzeki abangu-10, selivele liphezulu kakhulu ekugxilweni, futhi kukhona abahlinzeki abangu-3-4 kuphela bezinkampani zangaphandle ezizinzile. Ngakho-ke sikholelwa ukuthi ukuhola kuyazuzisa. Iziphakamiso: i-nano yesiJalimane, i-Guoxuan high-tech, i-BYD ne-Yutong Bus.
