Bhatiri resimba rinonzi moyo wemotokari yemagetsi; mhando, zvinhu, simba, kuchengetedza kushanda, nezvimwewo zvebhatiri remotokari yemagetsi zvave zvakakosha "zviyero" uye "maparamita" ekuyera motokari yemagetsi. Parizvino, mari yebhatiri yemotokari yemagetsi inowanzoita 30% -40% yemotokari yose, iyo inogona kunzi ndiyo yakakosha accessory!
Parizvino, mabhatiri emagetsi anoshandiswa mumotokari dzemagetsi pamusika anowanzo kukamurwa kuita marudzi maviri: ternary lithium mabhatiri uye lithium iron phosphate mabhatiri. Zvadaro, regai ndiongorore muchidimbu kusiyana uye zvakanakira uye kuipa kwemabhatiri maviri:
1. Zvinhu zvakasiyana:
Chikonzero nei ichinzi "ternary lithium" uye "lithium iron phosphate" inonyanya kureva makemikari e "positive electrode material" yebhatiri remagetsi;
"Ternary lithium":
Iyo cathode zvinhu inoshandisa lithium nickel cobalt manganate (Li(NiCoMn) O2) ternary cathode zvinhu zve lithium mabhatiri. Nyaya iyi inosanganisa zvakanakira lithium cobalt oxide, lithium nickel oxide uye lithium manganate, ichigadzira matatu-phase eutectic system yezvinhu zvitatu. Nekuda kweiyo ternary synergistic mhedzisiro, kuita kwayo kwakazara kuri nani pane chero musanganiswa musanganiswa.
"Lithium iron phosphate":
inoreva mabhatiri e-lithium-ion anoshandisa lithium iron phosphate sechinhu checathode. Hunhu hwayo ndehwekuti haina masimbi anokosha akadai secobalt, mutengo wemidziyo wakaderera, uye zviwanikwa zvephosphorus nesimbi zvakazara panyika, saka hapazovi nematambudziko ekupa.
pfupiso
Ternary lithium zvinhu zvinoshomeka uye zviri kusimuka nekukurumidza kukura kwemotokari dzemagetsi. Mitengo yavo yakakwira uye inodzivirirwa zvakanyanya nepamusoro pemvura mbishi zvinhu. Ichi chimiro che ternary lithium panguva ino;
Lithium iron phosphate, nekuti inoshandisa yakaderera reshiyo yesimbi isingawanzo / yakakosha simbi uye inonyanya kudhura uye yakawanda iron, inochipa kupfuura ternary lithium mabhatiri uye haina kukanganiswa nepamusoro pemvura mbishi. Uyu ndiwo hunhu hwawo.
2. Kusiyana kwesimba density:
"Ternary lithium bhatiri": Nekuda kwekushandiswa kweakawanda anoshanda esimbi mabhatiri, iyo simba density yeakadzika ternary lithium mabhatiri anowanzo (140wh / kg ~ 160 wh / kg), iyo yakadzikira pane iyo ternary mabhatiri ane yakakwira nickel ratio. 160 wh / kg～180 wh/kg); humwe huremu simba density inogona kusvika 180Wh-240Wh/kg.
"Lithium iron phosphate": Kuwanda kwesimba kunowanzoita 90-110 W/kg; mamwe mabhatiri e lithium iron phosphate, akadai semabhatiri eblade, ane simba remagetsi rinosvika 120W/kg-140W/kg.
pfupiso
Mukana wakakura we "ternary lithium bhatiri" pamusoro pe "lithium iron phosphate" ndeye yakakwirira simba density uye nekukurumidza kuchaja.
3. Yakasiyana tembiricha inochinjika:
Kudzikira-tembiricha kuramba:
Ternary lithium bhatiri: Ternary lithium bhatiri ine yakanakisa yakaderera-tembiricha kuita uye inogona kuchengetedza inosvika 70% ~ 80% yeyakajairika bhatiri huwandu pa -20°C.
Lithium iron phosphate: Isingamiri kune tembiricha yakaderera: Kana tembiricha iri pasi -10°C,
lithium iron phosphate mabhatiri anoora nekukurumidza. Lithium iron phosphate mabhatiri anogona chete kuchengetedza anenge 50% kusvika 60% yeyakajairika bhatiri huwandu pa -20.°C.
pfupiso
Pane musiyano mukuru mukushanduka kwekushisa pakati pe "ternary lithium bhatiri" uye "lithium iron phosphate"; "lithium iron phosphate" inonyanya kupikisa kutonhora kwakanyanya; uye iyo yakaderera-inodzivirira "ternary lithium bhatiri" ine hupenyu huri nani hwebhatiri munzvimbo dzekuchamhembe kana chando.
4. Hupenyu hurefu hwakasiyana:
Kana iyo yakasara simba / yekutanga kugona = 80% inoshandiswa seyekupedzisira bvunzo, bvunzo:
Lithium iron phosphate bhatiri mapaketi ane hupenyu hwakareba kutenderera kupfuura lead-asidhi mabhatiri uye ternary lithium mabhatiri. "Hupenyu hurefu" hwemabhatiri edu e-lead-asidhi akaiswa mumotokari anongosvika ka300 chete; iyo ternary lithium bhatiri inogona kufungidzira kusvika ku2,000 nguva, asi mukushandiswa chaiko, iyo simba ichaora kusvika 60% mushure menguva dzinenge 1,000; uye hupenyu chaihwo hwemabhatiri e-lithium iron phosphate ndeye 2000 nguva, kuchine 95% kukwanisa panguva ino, uye hupenyu hwayo hwekutenderera hunosvika kupfuura 3000 nguva.
pfupiso
Mabhatiri emagetsi ndiwo musimboti wetekinoroji wemabhatiri. Mhando mbiri dzemabhatiri e-lithium dzinogara kwenguva refu. Tichingotaura, hupenyu hweternary lithium bhatiri ndeye 2,000 kuchaja uye kuburitsa kutenderera. Kunyangwe tikachaja kamwe pazuva, inogona kugara kweanopfuura makore mashanu.
5. Mitengo yakasiyana:
Sezvo mabhatiri e-lithium iron phosphate asina simbi yakakosha, mutengo wezvigadzirwa zvinogona kudzikiswa zvakanyanya. Ternary lithium mabhatiri anoshandisa lithium nickel cobalt manganate seyakanaka electrode zvinhu uye graphite seyakaipa electrode zvinhu, saka mutengo unodhura zvakanyanya kupfuura lithium iron phosphate mabhatiri.
Iyo ternary lithium bhatiri inonyanya kushandisa iyo ternary cathode zvinhu zve "lithium nickel cobalt manganate" kana "lithium nickel cobalt aluminate" seyakanaka electrode, kunyanya kushandisa nickel munyu, cobalt munyu, uye manganese munyu semidziyo. Iyo "cobalt element" mune izvi zviviri cathode zvinhu isimbi yakakosha. Zvinoenderana nedata kubva kumawebhusaiti akakodzera, mutengo wemumba wecobalt simbi i413,000 yuan/ton, uye nekudzikiswa kwezvinhu, mutengo unoramba uchikwira. Parizvino, mutengo we ternary lithium mabhatiri ndeye 0.85-1 yuan / wh, uye ikozvino iri kukwira nemusika kudiwa; mutengo we lithium iron phosphate mabhatiri asina masimbi anokosha anongosvika 0.58-0.6 yuan/wh.
pfupiso
Sezvo "lithium iron phosphate" isina masimbi anokosha akadai secobalt, mutengo wayo unongori 0.5-0.7 nguva yebhatiri ye ternary lithium; mutengo wakachipa mukana mukuru welithium iron phosphate.
Pfupisa
Chikonzero nei mota dzemagetsi dzakabudirira mumakore achangopfuura uye dzinomiririra kutungamira kweramangwana rekuvandudza mota, zvichipa vatengi chiitiko chiri nani, zvakanyanya kukonzerwa nekuenderera mberi kwekuvandudza kwesimba rebhatiri tekinoroji.
