Tham txog roj teeb pob core Cheebtsam-battery cell (1)

Feem ntau ntawm cov roj teeb uas siv nyob rau hauv lub ntsiab PACKs ntawm lub khw yog lithium hlau phosphate roj teeb.

"Lithium hlau phosphate roj teeb", lub npe tag nrho ntawm lithium hlau phosphate lithium ion roj teeb, lub npe ntev dhau lawm, hu ua lithium hlau phosphate roj teeb.Vim tias nws qhov kev ua tau zoo tshwj xeeb rau kev siv fais fab, lo lus "lub zog" ntxiv rau lub npe, uas yog, lithium hlau phosphate fais fab roj teeb.Nws tseem hu ua "lithium hlau (LiFe) lub zog roj teeb".

txoj cai ua haujlwm

Lithium hlau phosphate roj teeb hais txog lub roj teeb lithium ion siv lithium hlau phosphate ua cov khoom siv hluav taws xob zoo.Cov ntaub ntawv cathode ntawm lithium-ion roj teeb feem ntau suav nrog lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary cov ntaub ntawv, lithium hlau phosphate, thiab lwm yam. .

qhov tseem ceeb

Hauv kev lag luam hlau, cobalt (Co) yog qhov kim tshaj plaws, thiab tsis muaj ntau qhov chaw cia, npib tsib xee (Ni) thiab manganese (Mn) pheej yig dua, thiab hlau (Fe) muaj ntau qhov chaw cia.Tus nqi ntawm cov khoom siv cathode kuj yog nyob rau hauv txoj kab nrog cov hlau no.Yog li ntawd, lithium-ion roj teeb ua los ntawm LiFePO4 cov ntaub ntawv cathode yuav tsum pheej yig heev.Lwm feature ntawm nws yog hais tias nws yog ib puag ncig tus phooj ywg thiab tsis-polluting.

Raws li lub roj teeb rechargeable, qhov yuav tsum tau muaj yog: muaj peev xwm, siab tso zis voltage, zoo them-tso lub voj voog kev ua tau zoo, ruaj khov tso zis voltage, high-tam sim no tus nqi-tso tawm, electrochemical stability, thiab kev nyab xeeb ntawm kev siv (tsis yog vim overcharge, overdischarge thiab luv luv. circuit).Nws tuaj yeem ua rau combustion lossis tawg vim kev ua haujlwm tsis raug), kev ua haujlwm kub ntau, tsis muaj tshuaj lom lossis tsis muaj tshuaj lom, thiab tsis muaj kuab paug rau ib puag ncig.LiFePO4 roj teeb uas siv LiFePO4 raws li qhov zoo electrode muaj kev ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm cov pa paug loj (5 ~ 10C paug), ruaj khov paug voltage, kev nyab xeeb (tsis kub kub, tsis tawg), lub neej (lub sij hawm voj voog), tsis muaj kuab paug rau ib puag ncig, nws yog qhov zoo tshaj plaws, thiab tam sim no yog qhov zoo tshaj plaws high-tam sim no tso zis hluav taws xob roj teeb.
