01 - lithium iron phosphate iri kuwedzera

Bhatiri reLithium rine zvakanakira zvehukuru hudiki, huremu hushoma, kuchaja nekukurumidza uye kugara kwenguva refu. Rinogona kuonekwa kubva kubhatiri refoni nebhatiri remota. Pakati pawo, bhatiri reLithium Iron phosphate nebhatiri reTenary Material ndiwo matavi maviri makuru ebhatiri reLithium parizvino.

Panyaya dzekuchengetedza, mumotokari dzevatakuri nemotokari dzebasa rakakosha, bhatiri remagetsi re lithium iron phosphate rine mutengo wakaderera, tekinoroji yechigadzirwa yakakura uye yakachengeteka yave kushandiswa zvakanyanya. Bhatiri re ternary lithium rine simba rakanyanya rinoshandiswa zvakanyanya mumotokari dzevatakuri. Mune zvimwe zviziviso zvitsva, huwandu hwemabhatiri e lithium iron phosphate mumunda wemotokari dzevatakuri hwakawedzera kubva pasi pe20% kare kusvika pa30%.

Lithium iron phosphate (LiFePO4) ndeimwe yezvinhu zvinoshandiswa zvakanyanya pakugadzira mabhatiri e lithium-ion. Ine kugadzikana kwakanaka kwekupisa, kunyorova kushoma uye kushanda zvakanaka kwechaja kana yakachajwa zvizere. Ndiyo inonyanya kutariswa mukutsvaga, kugadzira nekuvandudza mabhatiri e lithium-ion ane simba uye kuchengetedza simba. Zvisinei, nekuda kwekuganhurirwa kwechimiro chayo, bhatiri re lithium-ion rine lithium iron phosphate sechinhu chakanaka harina conductivity yakanaka, kupararira kwe lithium ion kunononoka, uye kushanda kwakashata kwekuburitsa pakupisa kwakaderera. Izvi zvinoguma nekufamba kwakaderera kwemotokari dzekare dzakashongedzerwa ne lithium iron phosphate battery, kunyanya kana tembiricha yakaderera.

Kuti titsvage budiriro yekufamba kwenguva refu, kunyanya mushure mekunge mutemo wekubatsira mota itsva une simba waisa zvinodiwa zvakanyanya zvekufamba kwenguva refu, kuwanda kwesimba, kushandiswa kwesimba nezvimwe zvinhu, kunyangwe bhatiri re lithium iron phosphate rakatanga kushanda pamusika kare, bhatiri re lithium ternary rine simba rakawanda rave zvishoma nezvishoma rave chinhu chikuru mumusika wemotokari itsva dzine simba. Zvinogona kuonekwa kubva kuziviso yazvino yekuti kunyangwe chikamu chebhatiri re lithium iron phosphate mumunda wemotokari dzevatakuri chakawedzera, chikamu chebhatiri re lithium ternary chichiri kusvika 70%.

02 - kuchengetedzeka ndiyo mukana mukuru

Nickel cobalt aruminiyamu kana nickel cobalt manganese zvinowanzo shandiswa sezvinhu zveanode zvemabhatiri e-ternary lithium, asi kushanda kwakanyanya kwezvinhu izvi hakungounzi simba rakawanda chete, asiwo kunounza njodzi huru dzekuchengetedza. Nhamba dzisina kukwana dzinoratidza kuti muna 2019, huwandu hwetsaona dzemoto dzinozvibatisa dzega hwakataurwa ka14 kupfuura muna 2018, uye mhando dzakadai seTesla, Weilai, BAIC neWeima dzakakonzera tsaona dzega dzinozvibatisa dzega.

Zvinogona kuonekwa kubva mutsaona kuti moto unonyanya kuitika panguva yekuchaja, kana kuti mushure mekuchaja, nekuti bhatiri rinokwira tembiricha panguva yekushanda kwenguva refu. Kana tembiricha yebhatiri re ternary lithium yadarika 200 ° C, chinhu chakanaka chinoora nyore nyore, uye oxidation reaction inotungamira mukumhanya kwekupisa uye kupisa zvine simba. Maumbirwo emuorivhi e lithium iron phosphate anounza kugadzikana kwekupisa kwakanyanya, uye tembiricha yayo yekumhanya inosvika 800 ° C, uye kugadzirwa kwegasi kushoma, saka yakachengeteka. Ichi ndicho chikonzero zvakare, zvichibva pakufunga nezvekuchengetedza, mabhazi matsva esimba anowanzo shandisa mabhatiri e lithium iron phosphate, nepo mabhazi matsva esimba anoshandisa mabhatiri e lithium ternary asingakwanise kupinda mukatalogu yemotokari itsva dzesimba kuti dzikurudzirwe uye dzishandiswe kwenguva pfupi.

Munguva pfupi yapfuura, mota mbiri dzemagetsi dzeChangan Auchan dzakashandisa bhatiri re lithium iron phosphate, iro rakasiyana nemakambani emotokari anonyanya kutarisa mota. Mhando mbiri dzeChangan Auchan iSUV neMPV. Xiong zewei, mutevedzeri wemaneja mukuru weChang'an Auchan Research Institute, akaudza mutori wenhau kuti: "Izvi zvinoratidza kuti Auchan yapinda zviri pamutemo munguva yemagetsi mushure memakore maviri ekuedza."

Nezvekuti sei bhatiri re lithium iron phosphate richishandiswa, Xiong akati kuchengetedzeka kwemotokari itsva kwagara kuri imwe ye "nzvimbo dzinorwadza" dzevashandisi, uye ndiyo inonyanya kutariswa nemakambani. Tichifunga nezveizvi, paki yebhatiri re lithium iron phosphate inotakurwa nemotokari itsva yapedza bvunzo yekupisa moto inodarika 1300 ° C, - 20 ° C low tembiricha yakamira, 3.5% salt solution yakamira, 11 kN external pressure impact, nezvimwewo, uye yakawana mhinduro yekuchengetedza mabhatiri e "four not fear" ekuti "not fear of heat, not cold, not water, not fear of impact".

Sekureva kwemishumo, Changan Auchan x7ev ine mota inogara iine magineti synchronous ine simba guru re150KW, ine makiromita anokwana 405 ekufamba uye bhatiri rinogara kwenguva refu rine mabhatiri anokwana 3000 ekuchaja. Pakupisa kwakajairika, zvinongotora hafu yeawa chete kuwedzera makiromita anokwana 300 ekufamba. "Kutaura chokwadi, nekuda kwekuvapo kwesystem yekudzoreredza simba remabhureki, kutsungirira kwemotokari kunogona kusvika makiromita angangoita 420 mumamiriro ekushanda emaguta." Xiong akawedzera.

Zvinoenderana nehurongwa hwekuvandudza indasitiri yemotokari dzemagetsi (2021-2035) (Draft for comments) hwakaburitswa neBazi reIndasitiri neInformation Technology, kutengeswa kwemotokari dzemagetsi matsva kuchave ne25% panosvika 2025. Zvinogona kuonekwa kuti huwandu hwemotokari dzemagetsi itsva hucharamba huchiwedzera mune ramangwana. Mumamiriro ezvinhu aya, kusanganisira Chang'an Automobile, makambani emotokari dzemhando yepamusoro ari kukurumidzisa kurongeka kwemusika wemotokari dzemagetsi matsva.
