01 – i-lithium iron phosphate ibonisa umkhwa okhulayo

Ibhetri yeLithium ineengenelo zobukhulu obuncinci, ubunzima obulula, ukutshaja ngokukhawuleza kunye nokuqina. Ingabonakala kwibhetri yeselfowuni kunye nebhetri yemoto. Phakathi kwazo, ibhetri ye-lithium iron phosphate kunye nebhetri yezinto ezisetyenziswa kwi-ternary ziindawo ezimbini eziphambili zebhetri yeLithium okwangoku.

Ngokweemfuno zokhuseleko, kwicandelo leemoto zabakhweli kunye nezithuthi zeenjongo ezikhethekileyo, ibhetri yamandla ye-lithium iron phosphate enexabiso eliphantsi, ubuchwepheshe bemveliso obukhulileyo nobukhuselekileyo busetyenzisiwe ngesantya esiphezulu. Ibhetri ye-ternary lithium enegunya elithile eliphezulu isetyenziswa kakhulu kwicandelo leemoto zabakhweli. Kwiqela elitsha lezibhengezo, umlinganiselo weebhetri ze-lithium iron phosphate kwicandelo leemoto zabakhweli unyuke ukusuka ngaphantsi kwe-20% ngaphambili ukuya malunga ne-30%.

I-Lithium iron phosphate (LiFePO4) yenye yezinto ezisetyenziswa kakhulu kwi-cathode kwiibhetri ze-lithium-ion. Izinzile kakuhle kubushushu, ifunxa kancinci umswakama kwaye isebenza kakuhle kakhulu kwi-charge discharge cycle phantsi kwe-charge epheleleyo. Yindawo ephambili kuphando, kwimveliso nakwiphuhliso kwicandelo lamandla kunye nokugcinwa kwamandla ebhetri ye-lithium-ion. Nangona kunjalo, ngenxa yokunciphisa ulwakhiwo lwayo, ibhetri ye-lithium-ion ene-lithium iron phosphate njengezinto ezilungileyo ayinakho ukuqhuba kakuhle, isantya sokusasazwa kancinci kwe-lithium ion, kwaye ayisebenzi kakuhle kwi-discharge kubushushu obuphantsi. Oku kubangela ukuba izithuthi zokuqala zihambe kancinci, ingakumbi xa ziphantsi kobushushu.

Ukuze kufunyanwe impumelelo kwi-mileage yokunyamezela, ingakumbi emva kokuba umgaqo-nkqubo wenkxaso-mali wezithuthi ezintsha zamandla umisele phambili iimfuno eziphezulu ze-mileage yokunyamezela izithuthi, uxinano lwamandla, ukusetyenziswa kwamandla kunye nezinye izinto, nangona ibhetri ye-lithium iron phosphate ithathe indawo kwimarike kwangethuba, ibhetri ye-ternary lithium enoxinano lwamandla aphezulu iye yaba yinto ephambili kwimarike yezithuthi ezintsha zamandla. Oku kubonakala kwisibhengezo samva nje sokuba nangona umlinganiselo webhetri ye-lithium iron phosphate kwicandelo lezithuthi zabakhweli uye waphinda wanda, umlinganiselo webhetri ye-lithium ternary usemalunga ne-70%.

02 – ukhuseleko yeyona nzuzo inkulu

I-aluminium ye-nickel cobalt okanye i-nickel cobalt manganese zihlala zisetyenziswa njengezixhobo ze-anode kwiibhetri ze-ternary lithium, kodwa umsebenzi ophezulu wezixhobo awuzisi nje kuphela uxinano lwamandla aphezulu, kodwa uzisa neengozi zokhuseleko eziphezulu. Izibalo ezingaphelelanga zibonisa ukuba ngo-2019, inani leengozi zokuzitshisa ezizenzekelayo kwizithuthi ezintsha zamandla likhankanywe ngokuphindwe ka-14 ngaphezu kwelo lango-2018, kwaye iimpawu ezifana neTesla, Weilai, BAIC kunye neWeima ziye zaqala iingozi zokuzitshisa ezizenzekelayo ngokulandelelana.

Kuyabonakala kwingozi ukuba umlilo uvela kakhulu kwinkqubo yokutshaja, okanye emva nje kokutshaja, kuba ibhetri iya kunyuka kubushushu ngexesha lokusebenza ixesha elide. Xa ubushushu bebhetri ye-ternary lithium bungaphezulu kwama-200 ° C, izinto ezilungileyo kulula ukuzibolisa, kwaye impendulo ye-oxidation ikhokelela ekubalekeni okukhawulezayo kobushushu kunye nokutsha okunamandla. Ulwakhiwo lwe-olivine ye-lithium iron phosphate luzisa uzinzo lobushushu obuphezulu, kwaye ubushushu bayo obubalekayo bufikelela kuma-800 ° C, kunye nemveliso encinci yegesi, ngoko ke ikhuselekile ngakumbi. Kungoko ke, ngokusekelwe kwingqwalasela yokhuseleko, iibhasi ezintsha zamandla zihlala zisebenzisa iibhetri ze-lithium iron phosphate, ngelixa iibhasi ezintsha zamandla ezisebenzisa iibhetri ze-ternary lithium zingakwazi okwethutyana ukungena kwikhathalogu yezithuthi ezintsha zamandla ukuze zikhuthazwe kwaye zisetyenziswe.

Kutshanje, iimoto ezimbini zombane zaseChangan Auchan zisebenzise ibhetri ye-lithium iron phosphate, eyahlukileyo kwiinkampani zezithuthi eziqhelekileyo ezigxile kwiimoto. Iimodeli ezimbini zeChangan Auchan yiSUV kunye neMPV. UXiong zewei, usekela-mphathi jikelele weChang'an Auchan Research Institute, uxelele intatheli wathi: "oku kubonisa ukuba iAuchan ingene ngokusesikweni kwixesha lamandla ombane emva kweminyaka emibini yemizamo."

Ngokuphathelele isizathu sokusetyenziswa kwebhetri ye-lithium iron phosphate, uXiong uthe ukhuseleko lwezithuthi ezintsha zamandla luhlala luphakathi "kweendawo ezibuhlungu" zabasebenzisi, kwaye lukwayeyona nto ixhalabisa kakhulu ngamashishini. Ngenxa yoku, iphakheji yebhetri ye-lithium iron phosphate ethwalwa yimoto entsha igqibe uvavanyo olulinganiselweyo lokubhaka ilangatye elingaphezulu kwe-1300 ° C, - ukuma kwiqondo lobushushu eliphantsi le-20 ° C, ukuma kwesisombululo setyuwa se-3.5%, impembelelo yoxinzelelo lwangaphandle lwe-11 kN, njl.njl., kwaye ifumene isisombululo sokhuseleko lwebhetri "esine esoyikayo" esithi "asoyiki ubushushu, asoyiki ukubanda, asoyiki amanzi, asoyiki ukubanda".

Ngokweengxelo, iChangan Auchan x7ev ixhotyiswe ngemoto esisigxina ehambelanayo nemagnethi enamandla aphezulu e-150KW, kunye ne-endurance mileage engaphezulu kwe-405 km kunye nebhetri ende kakhulu enokutshaja okujikeleza amaxesha angama-3000. Kubushushu obuqhelekileyo, kuthatha isiqingatha seyure kuphela ukongeza i-endurance mileage engaphezulu kwe-300 km. “Enyanisweni, ngenxa yokubakho kwenkqubo yokubuyisela amandla okubhuleka, i-endurance yesithuthi inokufikelela malunga ne-420 km phantsi kweemeko zokusebenza zasezidolophini.” wongeze watsho uXiong.

Ngokwesicwangciso sophuhliso lweshishini lezithuthi zamandla amatsha (2021-2035) (Uyilo lwezimvo) olukhutshwe yiSebe lezoShishino kunye neTekhnoloji yoLwazi, ukuthengiswa kwezithuthi zamandla amatsha kuya kubalelwa malunga ne-25% ngo-2025. Kuyabonakala ukuba inani lezithuthi zamandla amatsha liya kuqhubeka lisanda kwixesha elizayo. Kule meko, kuquka neChang'an Automobile, amashishini ezithuthi ezizimeleyo zemveli akhawulezisa ulwakhiwo lwemarike yezithuthi zamandla amatsha.
