Lub hwj chim roj teeb yog hu ua lub plawv ntawm lub tsheb hluav taws xob; Cov hom, cov khoom siv, muaj peev xwm, kev nyab xeeb ua tau, thiab lwm yam roj teeb tau ua qhov tseem ceeb "thiab" tsis ntsuas lub tsheb hluav taws xob. Tam sim no, lub roj teeb ntawm lub tsheb hluav taws xob feem ntau 30% -40% ntawm tag nrho cov tsheb, uas tuaj yeem hais tau tias yog cov khoom siv tseem ceeb!
Tam sim no, cov roj teeb hluav taws xob tseem ceeb siv hauv cov tsheb hluav taws xob ntawm lub khw muag khoom thiab cov roj teeb lithium lithium roj teeb. Tom ntej no, cia kuv hais luv luv ntawm qhov sib txawv thiab qhov zoo thiab qhov tsis zoo ntawm ob lub roj teeb:
1. Cov ntaub ntawv sib txawv:
Qhov laj thawj yog vim li cas thiaj hu ua "Ternary Lithium" thiab "Lithium Iron" Feem ntau yog hais txog cov khoom siv tshuaj lom neeg "ntawm lub hwj chim roj teeb;
"Ternary Lithium":
Lub cathode cov ntaub ntawv siv Lithium Nickel Cobalt mangalt manganate (lis (Nicomn) O2) Ternary Cathode roj teeb. Cov khoom siv no sib txuas nrog cov txiaj ntsig lithium cobalt oxide, lithium npib oxide thiab lithium mchoganate, sib sau ua peb-theem eutectic system ntawm peb cov khoom. Vim yog lub ternary synergistic nyhuv, nws qhov kev ua tau zoo dua yog qhov zoo dua li ib qho kev sib xyaw ua ke.
"Lithium iron phosphate":
Yog hais txog cov roj teeb lithium-ion siv cov hlau Lithium phosphate li cathode cov khoom. Nws cov yam ntxwv yog tias nws tsis muaj cov khoom muaj nuj nqis xws li cobalt, tus nqi phosphorus thiab cov khoom siv tau ntau nyob hauv lub ntiaj teb, yog li yuav tsis muaj teeb meem kev muab teeb meem.
lub ntsiab
Ternary Lithium cov ntaub ntawv yog tsawg thiab tab tom nce nrog txoj kev loj hlob ntawm hluav taws xob. Lawv tus nqi siab thiab lawv tau txwv los ntawm cov khoom siv raw. Nov yog tus yam ntxwv ntawm ternary lithium tam sim no;
Lithium iron phosphate, vim hais tias nws siv cov roj av tsawg / muaj cov hlau muaj txiaj ntsig thiab muaj kev cuam tshuam tsawg dua los ntawm cov khoom siv raw ntws tawm. Qhov no yog nws tus yam ntxwv.
2. Txawv zog sib txawv ntawm:
"Ternary Lithium roj teeb": Vim yog kev siv ntau cov roj teeb cov khoom siv lithuality lithium, uas yog qis dua ntawm cov roj teeb ternary nrog cov nickel ntau (160 wh / kgTom mu180 wh / kg); Qee qhov hnyav lub zog ntom ntom tuaj yeem ncav cuag 180wh-240wh / kg.
"Lithium iron phosphate": lub zog ntom feem ntau 90-110 w / kg; Qee cov roj teeb lithium tshiab ua lag luam, xws li hniav roj teeb, muaj lub zog siv roj teeb ntawm 120W / kg-140w / kg.
lub ntsiab
Qhov zoo tshaj plaws kom zoo dua ntawm "ternary lithium roj teeb" tshaj "lithium iron phosphate" yog nws lub zog loj ntom thiab ceev them ceev ceev.
3. Txawv Kub Txuas Ntxiv:
Tsawg-kub tsis kam:
Ternary Lithium roj teeb: Ternary Lithium roj teeb muaj kev ua tau zoo tshaj plaws tsawg-kub thiab tuaj yeem tswj tau 70% ntawm lub roj teeb sib xws ntawm -20°C.
Lithium iron phosphate: tsis tiv taus tsawg kub: thaum qhov kub nyob hauv qab -10°C,
Lithium iron phosphate roj teeb lwj sai sai. Lithium Iron phosphate roj teeb tuaj yeem tswj hwm 50% mus rau 60% ntawm lub roj teeb ib txwm muaj peev xwm nyob ntawm -20°C.
lub ntsiab
Muaj qhov sib txawv loj hauv qhov chaw kub yoog raws "Ternary Lithium roj teeb" thiab "Lithium Iron phosphate"; "Lithium iron phosphate" yog tiv taus ntau dua rau qhov kub; Thiab cov roj teeb uas muaj hluav taws kub tsawg-tiv taus "Ternary Lithium roj teeb" muaj roj teeb zoo dua nyob rau sab qaum teb lossis lub caij ntuj no.
4. Txawv lub neej txawv:
Yog tias qhov muaj peev xwm ntxiv / pib muaj peev xwm = 80% yog siv raws li kev sim kawg taw tes, sim:
Lithium Iron phosphate cov pob muaj roj ntsha muaj lub neej ntev dua li cov roj teeb thiab cov roj ntsha ternary lithium roj teeb. Lub "lub neej ntev tshaj plaws" ntawm peb lub tsheb-mounted coj-acid roj teeb tsuas yog kwv yees li 300 lub sij hawm; Lub roj teeb Lithium lithium tuaj yeem ua raws li 2,000 zaug, tab sis hauv kev siv tiag tiag, lub peev xwm yuav lwj mus rau 60% tom qab txog 1,000 zaus; Thiab lub neej tiag tiag ntawm cov roj teeb ntsha posphate roj teeb yog 2000 zaug, tseem muaj peev xwm nyob rau lub sijhawm no, thiab nws lub sijhawm ua haujlwm lub sijhawm nce mus txog ntau dua 3000 zaug.
lub ntsiab
Lub hwj chim roj teeb yog cov thev naus laus zis pinnacle ntawm cov roj teeb. Ob hom roj teeb lithium muaj zog yog tus neeg ruaj khov. Atoretically hais lus, kav lub neej ntawm ib lub ternary lithium roj teeb yog 2,000 tus nqi thiab kev tawm mus ncig. Txawm hais tias peb yuav tsub nws ib zaug ib hnub, nws tuaj yeem nyob ntev tshaj 5 xyoos.
5. Cov nqi sib txawv:
Txij li lithium iron phosphate roj teeb tsis muaj cov khoom siv hlau, tus nqi ntawm cov ntaub ntawv raw tuaj yeem txo qis tsawg. Cov roj ntsha lithaium lithium nickel khi cov khoom siv hluav taws xob thiab cov nqi tsis zoo rau cov roj teeb lithium pharies.
The ternary lithium battery mainly uses the ternary cathode material of "lithium nickel cobalt manganate" or "lithium nickel cobalt aluminate" as the positive electrode, mainly using nickel salt, cobalt salt, and manganese salt as raw materials. Lub "cobalt lub caij" hauv ob lub canhode cov ntaub ntawv yog cov hlau muaj nuj nqis. Raws li cov ntaub ntawv los ntawm cov vev xaib muaj feem xyuam ntawm cobalt tus nqi yog 413,000 yuan / tuj, thiab nrog rau kev txo cov khoom siv, tus nqi txuas ntxiv mus. Tam sim no, tus nqi ntawm ternary Lithium roj teeb yog 0.85-1 Yuan / Wh, thiab nws yog tam sim no nce nrog kev thov kev lag luam; Tus nqi ntawm Lithium Iron phosphate roj teeb uas tsis muaj cov khoom muaj txiaj ntsig tsuas yog hais txog 0.58-0.6 yuan / wh.
lub ntsiab
Txij li "Lithium Iron phosphate" tsis muaj cov hlau sib luag xws li cobalt, nws tus nqi tsuas yog 0.5-0.7 lub sij hawm ntawm ternary lithium roj teeb; Tus nqi pheej yig yog qhov tseem ceeb ntawm cov iron phosphate.
Lub ntsiab
Qhov laj thawj yog vim li cas cov tsheb hluav taws xob tau siv zog tsis ntev los no, muab cov neeg siv khoom lag luam yav tom ntej ntawm kev txhim kho hluav taws xob thev naus laus zis.
