Inokubonwa ukuba iindleko zezinto ekrwada zinokwahlulwa zibe ziibhloko ezintathu ezinkulu kwibhetri ye-LFP, enye yazo zizinto ezine eziphambili (ezilungileyo, i-electrode engalunganga, i-diaphragm, i-electrolyte), i-accounting yeendleko zizonke malunga ne-35%, i-Pack ithatha i-30%, i-Surplus 35% kwezinye izinto eziluhlaza kunye namacandelo. Ngokutsho kolu lwazi lungentla, sinika oku kulandelayo ingcinga yokulinganisa iindleko: 1) Umthamo webhetri ye-blade malunga ne-50% ephezulu kunobuninzi bamandla.

Xa ixabiso lentlawulo lihlala lihlala, umthamo uyancipha ngaphezu kwesinye kwisithathu, ukwenzela ukuba i-aluminium igubungele i-shell cover iqhutywe. Ipakethe yexabiso, kucingwa ukuba i-33% iyancipha i-2) Amandla, i-artificial, indleko yokuvelisa, kunye nokwehla kwe-BMS ngenxa yokulungiswa kwenkqubo kunye nokunciphisa iindawo, kucingelwa ukuba i-20% yokunciphisa i-3) iphinda icinge ukuba imathiriyeli eluhlaza (kubandakanya i-electrode efanelekileyo, i-electrode engalunganga, i-diaphragm, i-electrolyte, i-foil yobhedu, iMethyl, i-20 yexabiso lexabiso le-LFP lilonke linokuhla ngexabiso le-LFP). 0.696 yuan / WH ukuya 24.

3% ukuya 0.527 yuan / WH. 4) Ukuqhubela phambili ukuqwalasela umda wengeniso yenkampani ingasetyenziselwa ukufumana amaxabiso okuthengisa okwenene, njengoko kubonisiwe kwi-Figure 35, ibhetri ye-blade kunye nendlela ye-CTP iya kukhokela kuphela kwiimoto zorhwebo, nangona i-BYD ibhengeze, indlela yebhetri ye-blade iya kusetyenziswa ngokurhweba kwi-Han Nangona kunjalo, izithuthi zorhwebo ziya kuphinda zibe yindlela yokusebenzisa.

Sikholelwa ukuba i-BYD isetyenziselwa urhwebo kwimoto yethu yabakhweli, oko kukuthi igqobhoze ingqiqo yemizi-mveliso ngokubanzi: ubugcisa obutsha buhlala buhambela phambili kwizithuthi zorhwebo, kwaye iimoto zabakhweli ziya kuba zilumke ngakumbi. I-BYD isebenzisa iibhetri ze-blade kwimoto yayo, ngokungathandabuzekiyo kwisantya sokunyusa imoto yomkhweli. Enyanisweni, ibhetri ye-blade kunye nendlela ye-CTP iyafana, kwaye ukwenzela ukunciphisa iindleko, ngelixa ibhetri ye-monomer inkulu, kwaye i-lithium iron phosphate ikhethwa.

Ngokusekelwe kwi-2019, kukho izityalo ezininzi zomatshini wokuqala wokusebenzisa indlela ye-CTP yokufumana uvavanyo, ngoko le teknoloji kulindeleke ukuba isebenzise le teknoloji ngo-2020. Ngokuhambelana neengcinga ezingentla, sibala iimitha ezili-10 okanye ngaphezulu, iindleko zebhetri ziyancipha nge-30%, kwaye ixabiso lebhetri liyancipha ukusuka kwi-225,000 ukuya kwi-158,000. Xa kungekho nkxaso-mali, umyinge wengeniso yengeniso ungagcinwa.

Silindele ukuba ibhetri ye-phosphate&39;s tamite ka-2020 iya kuphuculwa ngakumbi kwiimoto zorhwebo. Ukusuka kwimbono yotyalo-mali, iphosphite enyukayo ibekwe, kunye nokuphuculwa komda wengeniso yesithuthi soshishino. Ukusukela ekunyukeni kwayo yonke i-lithium iron phosphate idlule kwi-shuffle yeminyaka emithathu, ukuxinana kweshishini kuphezulu.

Kwikhonkco loshishino, ukuba ufikelela kubaxhasi be-10, sele sele iphezulu kakhulu ekugxininiseni, kwaye kukho kuphela ababoneleli be-3-4 kuphela ababonelela ngokuzinza komntu wesithathu. Ke sikholelwa ukuba i-leadload iyanceda. Iingcebiso: i-nano yaseJamani, i-Guoxuan high-tech, i-BYD kunye ne-Yutong Bus.
