Ixabiso eliphezulu lezinto ezikrwada zezinto ezisetyenziswa kwi-ternary liya kuba nefuthe elibi ekukhuthazeni iibhetri ze-ternary lithium. I-Cobalt yeyona ntsimbi ibiza kakhulu kwiibhetri zamandla. Emva kokusikwa okuliqela, umndilili we-electrolytic cobalt ngetoni nganye umalunga ne-280000 yuan. Izinto ezikrwada zebhetri ye-lithium iron phosphate zityebile kwi-phosphorus kunye ne-iron, ngoko ke iindleko kulula ukuzilawula. Ke ngoko, nangona ibhetri ye-ternary lithium inokuphucula kakhulu uluhlu lwezithuthi zamandla amatsha, ngenxa yokhuseleko kunye nokuqwalaselwa kweendleko, abavelisi abakawubeki phantsi uphando lobuchwephesha kunye nophuhliso lwebhetri ye-lithium iron phosphate.

Kunyaka ophelileyo, i-Ningde era ikhuphe ubuchwepheshe be-CTP (ukuya kwi-cell to pack). Ngokwedatha ekhutshwe yi-Ningde times, i-CTP inokunyusa izinga lokusetyenziswa kwe-volume pack yebhetri nge-15%-20%, inciphise inani leenxalenye ze-battery pack ngama-40%, inyuse ukusebenza kakuhle kwemveliso ngama-50%, kwaye inyuse uxinano lwamandla e-battery pack nge-10%-15%. Kwi-CTP, amashishini asekhaya afana ne-BAIC new energy (EU5), i-Weilai automobile (ES6), i-Weima automobile kunye ne-Nezha automobile abonise ukuba aza kwamkela ubuchwepheshe be-Ningde era. I-VDL, umenzi weebhasi waseYurophu, ikwathe iza kuyizisa kulo nyaka.

Phantsi komkhwa wokuncipha kwezibonelelo zezithuthi ezintsha zamandla, xa kuthelekiswa nenkqubo yebhetri ye-lithium ye-3 yuan enexabiso elimalunga ne-0.8 yuan /wh, ixabiso langoku le-0.65 yuan /wh kwinkqubo ye-lithium iron phosphate linenzuzo kakhulu, ngakumbi emva kokuphuculwa kobuchwephesha, ibhetri ye-lithium iron phosphate ngoku inokunyusa i-mileage yesithuthi ukuya malunga ne-400 km, ngoko ke iqalile ukutsala ingqalelo yamashishini amaninzi ezithuthi. Idatha ibonisa ukuba ekupheleni kwexesha lotshintsho lwenkxaso ngoJulayi 2019, amandla afakiweyo e-lithium iron phosphate abandakanya i-48.8% ukusuka kwi-21.2% ngo-Agasti ukuya kwi-48.8% ngoDisemba.

ITesla, inkokheli yoshishino ebisoloko isebenzisa iibhetri ze-lithium-ion iminyaka emininzi, ngoku kufuneka yehlise iindleko zayo. Ngokwesicwangciso senkxaso-mali yezithuthi zamandla ezintsha zika-2020, iimodeli zetram ezingatshintshiselwano ezinee-yuan ezingaphezu kwama-300000 azinakufumana inkxaso-mali. Oku kubangele ukuba iTesla icinge ngokukhawulezisa inkqubo yokutshintshela kwiteknoloji yebhetri ye-lithium iron phosphate. Kutshanje, i-CEO yeTesla uMusk uthe kwingqungquthela yakhe elandelayo "yosuku lwebhetri", uza kugxila kumanqaku amabini, enye yiteknoloji yebhetri esebenza kakuhle, enye yibhetri engena-cobalt. Kwakuba nje iindaba ziphumile, amaxabiso e-cobalt aphesheya ehla.

Kukwaxelwa ukuba ixesha leTesla neleNingde lixoxa ngentsebenziswano yeebhetri ze-cobalt eziphantsi okanye ezingezizo ze-cobalt, kwaye i-lithium iron phosphate inokuhlangabezana neemfuno zemodeli esisiseko 3. Ngokutsho koMphathiswa wezoShishino kunye neTekhnoloji yoLwazi, imileji yokunyamezela yemodeli esisiseko 3 imalunga ne-450km, uxinano lwamandla enkqubo yebhetri lumalunga ne-140-150wh / kg, kwaye umthamo wombane uwonke umalunga ne-52kwh. Okwangoku, umbane obonelelwa lixesha leNingde ungenza ukuya kuthi ga kwi-80% kwimizuzu eli-15, kwaye uxinano lwamandla ebhetri enoyilo olukhaphukhaphu lunokufikelela kwi-155wh / kg, okwaneleyo ukuhlangabezana neemfuno ezingentla. Abanye abahlalutyi bathi ukuba iTesla isebenzisa ibhetri ye-lithium iron, ixabiso lebhetri enye kulindeleke ukuba linciphise i-7000-9000 yuan. Nangona kunjalo, iTesla iphendule ngelithi iibhetri ezingenayo i-cobalt azithethi ukuba iibhetri ze-lithium iron phosphate.

Ukongeza kwinzuzo yeendleko, uxinano lwamandla ebhetri ye-lithium iron phosphate xa ifika eluphahleni lobugcisa luye lwanda. Ekupheleni kukaMatshi kulo nyaka, i-BYD ikhuphe ibhetri yayo yeblade, ethi uxinano lwamandla ayo luphezulu ngama-50% kunebhetri yesinyithi yendabuko ngomthamo ofanayo. Ukongeza, xa kuthelekiswa nebhetri yesinyithi ye-lithium iron phosphate yendabuko, ixabiso lebhetri yeblade lincitshiswa ngama-20% ukuya kuma-30%.

Ibhetri ebizwa ngokuba yiblade eneneni yiteknoloji yokuphucula ngakumbi ukusebenza kakuhle kokuhlanganiswa kwebhetri ngokwandisa ubude beseli kunye nokwenza iseli ibe tyaba. Ngenxa yokuba iseli enye inde kwaye ityaba, ibizwa ngokuba yi-"blade". Kuyaqondakala ukuba iimodeli ezintsha zezithuthi zombane ze-BYD ziya kusebenzisa iteknoloji "yebhetri yeblade" kulo nyaka nakwelandelayo.

Kutshanje, uMphathiswa wezeMali, uMphathiswa wezeMizi-mveliso kunye nobuchwepheshe bolwazi, uMphathiswa wezeSayensi kunye nobuchwepheshe, kunye neKhomishini yoPhuhliso kunye noHlaziyo yeSizwe bakhuphe isaziso sokulungisa nokuphucula umgaqo-nkqubo wenkxaso-mali kwizithuthi ezintsha zamandla, nto leyo eyenze kwacaca ukuba inkqubo yezothutho lukawonke-wonke kunye nokufakelwa kombane kwizithuthi kwiindawo ezithile kufuneka ikhawuleziswe, kwaye kulindeleke ukuba ukhuseleko kunye neenzuzo zeendleko ze-lithium iron phosphate ziphuculwe ngakumbi. Kunokuqikelelwa ukuba ngokukhawuleziswa kancinci kancinci kwesantya sokufakelwa kombane kunye nokuphuculwa okuqhubekayo kobuchwepheshe obunxulumene nokhuseleko lwebhetri kunye noxinano lwamandla, amathuba okuba kubekho ibhetri ye-lithium iron phosphate kunye nebhetri ye-ternary lithium aya kuba makhulu kwixesha elizayo, kunokuba ngubani oza kuthatha indawo yazo.

Kuyafaneleka kwakhona ukuqaphela ukuba imfuno kwisiseko se-5g isikhululo iya kwenza imfuno yebhetri ye-lithium iron phosphate inyuke kakhulu iye kwi-10gwh, kwaye amandla afakiweyo ebhetri yamandla e-lithium iron phosphate ngo-2019 yi-20.8gwh. Kulindeleke ukuba isabelo semarike se-lithium iron phosphate sinyuke ngokukhawuleza ngo-2020, sizuze ekunciphiseni iindleko kunye nokuphuculwa kokhuphiswano okubangelwa yibhetri ye-lithium iron.
