2. Kub stability: Cov roj teeb no ua tau zoo nyob rau hauv ntau qhov kub thiab txias, txij li -40 ° C txog 60 ° C, uas yog qhov zoo rau kev siv dav hlau thiab tub rog.
3. Kev nyab xeeb: Ni-H2 roj teeb tsis tshua muaj thermal runaway piv rau Li-ion roj teeb. Qhov tsis muaj cov nplaim hluav taws xob hluav taws xob txo qhov kev pheej hmoo ntawm hluav taws lossis tawg, txhim kho lawv cov ntaub ntawv kev nyab xeeb.
4. Environmental Impact: Nickel thiab hydrogen muaj ntau dua thiab muaj kev phom sij tsawg dua lithium, cobalt, thiab lwm yam khoom siv hauv Li-ion roj teeb. Qhov no ua rau muaj kev cuam tshuam ib puag ncig qis dua.

Disadvantages ntawm Nickel-Hydrogen roj teeb

1. Zog Ceev: Thaum NI-H2 roj teeb muaj lub zog zoo, lawv feem ntau poob luv luv ntawm lub zog ntawm lub zog, uas txwv lawv siv hauv cov ntawv thov uas nyhav qhov hnyav thiab qhov loj me yog qhov tseem ceeb.
2. Nqi: Kev tsim cov roj teeb Ni-H2 feem ntau kim dua vim muaj cov txheej txheem tsim khoom nyuaj. Tus nqi siab dua no tuaj yeem ua rau muaj teeb meem loj rau kev saws me nyuam.
3. Tus nqi tso tawm tus kheej: Ni-H2 roj teeb muaj qhov tso tawm tus kheej ntau dua piv rau Li-ion roj teeb, uas tuaj yeem ua rau lub zog poob sai dua thaum tsis siv.

Lithium-ion roj teeb: Ib qho kev piav qhia

Cov roj teeb lithium-ion tau dhau los ua cov thev naus laus zis tseem ceeb rau cov khoom siv hluav taws xob portable, hluav taws xob tsheb, thiab lub zog tauj dua tshiab. Lawv muaj xws li ntau yam cathode cov ntaub ntawv, nrog lithium cobalt oxide thiab lithium hlau phosphate yog cov feem ntau.

Qhov zoo ntawm Lithium-ion roj teeb

1. Siab zog ceev: Li-ion roj teeb muab ib lub zog siab tshaj plaws ntawm cov cuab yeej siv roj teeb tam sim no, ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov chaw thiab qhov hnyav yog qhov tseem ceeb.
2. Kev txais yuav dav thiab Infrastructure: Kev siv ntau ntawm Li-ion roj teeb tau ua rau tsim cov khoom siv sib txuas thiab kev lag luam ntawm cov nplai, txo cov nqi thiab kev txhim kho thev naus laus zis los ntawm kev hloov pauv tas li.
3. Tsawg tus nqi tso tawm tus kheej: Li-ion roj teeb feem ntau muaj tus nqi qis dua tus kheej, tso cai rau lawv khaws cov nqi ntev dua thaum tsis siv.

Disadvantages ntawm Lithium-ion roj teeb

1. Kev txhawj xeeb txog kev nyab xeeb: Li-ion roj teeb muaj kev cuam tshuam rau thermal runaway, ua rau overheating thiab hluav taws kub. Lub xub ntiag ntawm cov hluav taws xob hluav taws xob ua rau muaj kev txhawj xeeb txog kev nyab xeeb, tshwj xeeb tshaj yog nyob rau hauv kev siv hluav taws xob siab.
2. Lub neej voj voog txwv: Thaum txhim kho, lub voj voog lub neej ntawm Li-ion roj teeb feem ntau luv dua li ntawm Ni-H2 roj teeb, yuav tsum tau hloov ntau zaus.
3. Teeb meem Environmental: Kev rho tawm thiab ua cov lithium thiab cobalt ua rau muaj kev txhawj xeeb txog ib puag ncig thiab kev coj ncaj ncees, suav nrog kev puas tsuaj hauv vaj tse thiab kev ua txhaum tib neeg txoj cai hauv kev ua haujlwm mining.

Ob lub nickel-hydrogen thiab lithium-ion roj teeb muaj qhov tshwj xeeb zoo thiab qhov tsis zoo uas yuav tsum tau txiav txim siab thaum ntsuas lawv qhov tsim nyog rau ntau yam kev siv. Nickel-hydrogen roj teeb muaj lub neej ntev, kev nyab xeeb, thiab ib puag ncig cov txiaj ntsig, ua rau lawv zoo tagnrho rau kev siv tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv aerospace. Nyob rau hauv sib piv, lithium-ion roj teeb ua tau zoo nyob rau hauv lub zog ceev thiab dav daim ntawv thov, ua rau lawv nyiam xaiv rau cov neeg siv khoom siv hluav taws xob thiab hluav taws xob tsheb.

Raws li lub zog toj roob hauv pes txuas ntxiv mus, kev tshawb fawb thiab kev txhim kho txuas ntxiv tuaj yeem ua rau kev txhim kho roj teeb thev naus laus zis uas sib xyaw ua ke lub zog ntawm ob lub tshuab thaum txo lawv qhov tsis muaj zog. Lub neej yav tom ntej ntawm lub zog cia yuav zoo li pob khawm ntawm ntau txoj hauv kev, siv cov yam ntxwv tshwj xeeb ntawm txhua lub roj teeb thev naus laus zis kom ua tau raws li qhov xav tau ntawm lub zog ruaj khov.
