Bhatiri remagetsi rinonzi moyo wemotokari yemagetsi; rudzi, zvinhu, kugona, mashandiro ekuchengetedza, nezvimwewo zvebhatiri remotokari yemagetsi zvave "zviyero" zvakakosha uye "zviyero" zvekuyera mota yemagetsi. Parizvino, mutengo webhatiri remotokari yemagetsi unowanzova 30%-40% yemotokari yese, izvo zvinogona kunzi chinhu chikuru chinobatsira!
Parizvino, mabhatiri emagetsi anoshandiswa mumotokari dzemagetsi ari pamusika anowanzo kupatsanurwa kuita mhando mbiri: mabhatiri e-ternary lithium uye mabhatiri e-lithium iron phosphate. Tevere, regai ndiongorore muchidimbu musiyano nezvakanaka nezvakaipa zvemabhatiri maviri aya:
1. Zvinhu zvakasiyana-siyana:
Chikonzero nei ichinzi "ternary lithium" uye "lithium iron phosphate" zvinonyanya kureva zvinhu zvemakemikari zve "positive electrode material" yebhatiri remagetsi;
"Ternary lithium":
Chinhu che cathode chinoshandisa lithium nickel cobalt manganate (Li(NiCoMn)O2) ternary cathode material ye lithium batterys. Chinhu ichi chinobatanidza zvakanakira lithium cobalt oxide, lithium nickel oxide uye lithium manganate, zvichigadzira system ye eutectic yezvikamu zvitatu. Nekuda kwe ternary synergistic effect, kushanda kwayo kwakazara kuri nani pane chero chinhu chimwe chete chakabatanidzwa.
"Lithium iron phosphate":
zvinoreva mabhatiri e lithium-ion anoshandisa lithium iron phosphate se cathode material. Hunhu hwayo ndehwekuti haina zvinhu zvesimbi zvinokosha zvakaita se cobalt, mutengo wezvinhu zvakabikwa wakaderera, uye zviwanikwa zve phosphorus nesimbi zvakawanda muvhu, saka hapazovi nematambudziko ekupa.
pfupiso
Zvinhu zveTernary lithium hazviwanikwe uye zviri kukwira nekukura nekukurumidza kwemotokari dzemagetsi. Mitengo yadzo yakakwira uye dzakaganhurirwa zvakanyanya nezvinhu zvekugadzira. Ichi ndicho chimiro cheTernary lithium pari zvino;
Lithium iron phosphate, nekuti inoshandisa huwandu hwakaderera hwesimbi dzisiri nyore kuwana/dzinokosha uye inonyanya kudhura uye yakawanda iron, yakachipa pane mabhatiri e ternary lithium uye hainyanyi kukanganiswa nezvinhu zvakagadzirwa ne ternary. Ndiwo hunhu hwayo.
2. Kuwanda kwesimba kwakasiyana:
"Ternary lithium battery": Nekuda kwekushandiswa kwezvinhu zvesimbi zvinoshanda zvakanyanya, huwandu hwesimba remabhatiri eTernary lithium akajairika hunowanzova (140wh/kg~160 wh/kg), iyo yakaderera pane iyo yemabhatiri eTernary ane nickel ratio yakakwira (160 wh/ kg).～180 wh/kg); huwandu hwesimba rehuremu hunogona kusvika 180Wh-240Wh/kg.
"Lithium iron phosphate": Kuwanda kwesimba kunowanzova 90-110 W/kg; mamwe mabhatiri matsva e lithium iron phosphate, akadai semabhatiri eblade, ane simba rinosvika 120W/kg-140W/kg.
pfupiso
Chinhu chikuru chinobatsira "ternary lithium battery" kupfuura "lithium iron phosphate" ndechekuti ine simba rakawanda uye inokurumidza kuchaja.
3. Kugona kuchinja tembiricha kwakasiyana:
Kudzivirira kupisa kwakaderera:
Bateri reTernary lithium: Bateri reTernary lithium rine mashandiro akanaka pakupisa kwakaderera uye rinogona kuchengetedza 70% ~ 80% yehuwandu hwebhatiri hwakajairika pa -20°C.
Lithium iron phosphate: Haigoni kubatwa nekupisa kwakaderera: Kana tembiricha iri pasi pe -10°C,
Mabhatiri eLithium Iron phosphate anoora nekukurumidza. Mabhatiri eLithium Iron phosphate anogona kuchengetedza 50% kusvika 60% chete yesimba rebhatiri rakajairika pa -20°C.
pfupiso
Pane musiyano mukuru mukuchinjika kwekushisa pakati pe "ternary lithium battery" ne "lithium iron phosphate"; "lithium iron phosphate" inodzivirira kupisa kwakanyanya; uye "ternary lithium battery" inodzivirira kupisa kwakanyanya ine hupenyu huri nani hwebhatiri munzvimbo dzekuchamhembe kana munguva yechando.
4. Nguva dzakasiyana dzehupenyu:
Kana huwandu hwasara/hunhu hwekutanga = 80% hukashandiswa senzvimbo yekupedzisira yekuedza, edza:
Mabhatiri eLithium iron phosphate ane hupenyu hwakareba kupfuura mabhatiri eLead-acid uye mabhatiri eTerry Lithium. "Hupenyu hwakareba" hwemabhatiri edu eLead-acid akaiswa mumotokari hunongova ka300 chete; bhatiri reTerry Lithium rinogona kugara kusvika ka2,000, asi parinoshandiswa chairo, simba rayo rinoora kusvika 60% mushure meka1,000; uye hupenyu chaihwo hwemabhatiri eLithium iron phosphate hunosvika ka2000, kuchine simba re95% panguva ino, uye hupenyu hwayo hweConceptual cycle hunosvika ka3000.
pfupiso
Mabhatiri emagetsi ndiwo anonyanya kukosha pamabhatiri. Marudzi ese emabhatiri e lithium anogara kwenguva refu. Panyaya yedzidziso, hupenyu hwebhatiri re lithium re ternary hunosvika zviuru zviviri zvekuchaja nekuburitsa magetsi. Kunyangwe tikarichaja kamwe chete pazuva, rinogona kugara kwemakore anopfuura mashanu.
5. Mitengo yakasiyana:
Sezvo mabhatiri e lithium iron phosphate asina zvinhu zvinokosha zvesimbi, mutengo wezvinhu zvakagadzirwa unogona kuderedzwa zvishoma. Mabhatiri e lithium ane ternary anoshandisa lithium nickel cobalt manganate se positive electrode material uye graphite se negative electrode material, saka mutengo wacho unodhura zvakanyanya kupfuura mabhatiri e lithium iron phosphate.
Bhatiri reTenary lithium rinonyanya kushandisa ternary cathode material ye "lithium nickel cobalt manganate" kana "lithium nickel cobalt aluminate" se positive electrode, kunyanya kushandisa nickel salt, cobalt salt, uye manganese salt sezvinhu zvisina kugadzirwa. "Cobalt element" iri muzvinhu zviviri izvi zve cathode isimbi inokosha. Sekureva kwedata kubva kumawebhusaiti akakodzera, mutengo wecobalt metal wemuno i413,000 yuan/ton, uye nekudzikira kwezvinhu, mutengo unoramba uchikwira. Parizvino, mutengo weternary lithium batteries i0.85-1 yuan/wh, uye parizvino uri kukwira nekudiwa kwemusika; mutengo we lithium iron phosphate batteries asina zvinhu zvesimbi inokosha inongova 0.58-0.6 yuan/wh.
pfupiso
Sezvo "lithium iron phosphate" isina simbi dzinokosha dzakadai se cobalt, mutengo wayo unongopfuura 0.5-0.7 pane mabhatiri e ternary lithium; mutengo wakachipa ndiwo mukana mukuru we lithium iron phosphate.
Pfupisa
Chikonzero nei mota dzemagetsi dzakabudirira mumakore achangopfuura uye dzichimiririra mafambiro ekuvandudzwa kwemotokari mune ramangwana, zvichipa vatengi ruzivo rwuri nani, zvakanyanya nekuda kwekuvandudzwa kuri kuitwa tekinoroji yemagetsi emabhatiri.
