Koj puas tsis nkag siab txog ntau yam kev xaiv roj teeb lithium rau koj qhov project tom ntej? Koj puas ua qhov sib txawv tseem ceeb ntawm cov thev naus laus zis lithium thawj thiab theem ob? Qhov kev xaiv no cuam tshuam rau txhua yam.

Qhov txawv tseem ceeb yog qhov rov them tau dua: cov roj teeb lithium thawj zaug tsis tuaj yeem rov them tau dua (siv ib zaug xwb), thaum cov roj teeb lithium thib ob tuaj yeem rov them tau dua . Qhov txawv tseem ceeb no yog los ntawm lawv cov tshuaj lom neeg sab hauv thiab kev tsim kho, cuam tshuam rau kev siv, tus nqi, thiab kev ua tau zoo.

Qhov thib ob sib txawv yog lithium hlau (thawj) los yog lithium alloy thiab lithium-ion (thib ob) raws li cov khoom tsis zoo electrode. Thiab thawj lub roj teeb lithium yog nrog lub zog siab ceev thiab kev ua haujlwm kub ntau. Cov roj teeb lithium tseem ceeb suav nrog LiSOCl2, LiSO2CL2, LiMnO2, LiSO2, LiFeS2 thiab lwm yam. Cov roj teeb lithium thib ob tseem hu ua lithium-ion roj teeb. Xws li LiCO2, LiMnO2, LiFePO4, NMC (ternary), thiab lwm yam.

Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau txhua tus engineer lossis tus thawj tswj khoom. Cia peb dhia mus rau hauv cov ntsiab lus kom ntseeg tau tias koj xaiv lub zog zoo. Nco ntsoov nyeem!

Cov roj teeb lithium yog dab tsi?

Tau ntsib nrog daim ntawv thov chaw taws teeb sensor xav tau lub zog ntev? Los yog tej zaum tsim ib lub cuab yeej uas hloov roj teeb nyuaj lossis tsis yooj yim sua? Xav txog thawj lithium.

Cov roj teeb lithium tseem ceeb yog cov roj teeb uas tsis tuaj yeem siv tau siv lithium hlau lossis lithium compounds ua cov anode.

Dab tsi yog qhov txawv ntawm thawj thiab theem nrab lithium roj teeb?

Koj puas xav txog qhov zoo ntawm kev siv roj teeb uas them tau dua thiab tsis them tau rau koj qhov project? Kev xaiv ntawm lithium thawj thiab lithium thib ob yog qhov tseem ceeb rau koj txoj kev tsim.

Qhov sib txawv tseem ceeb yog rechargeability. Cov roj teeb lithium tseem ceeb yog siv ib zaug thiab siv pov tseg, thaum cov roj teeb lithium thib ob (feem ntau hu ua lithium-ion) tuaj yeem siv tau thiab siv tau ntau zaus. Qhov no tshwm sim los ntawm qhov sib txawv hauv lawv cov khoom siv sab hauv thiab tshuaj lom neeg.

Deep Dive: Sib piv cov thawj thiab theem nrab lithium

Rau kev paub txog kev txiav txim siab, cov khoom tswj xyuas thiab cov kws tsim khoom xav tau kev sib piv kom ntxaws:

Lub roj teeb twg zoo dua, LFP lossis NMC?

Xav tau LFP thiab NMC rau koj daim ntawv thov roj teeb lithium rechargeable ? Qhov kev xaiv no hauv tsev neeg lithium thib ob yog qhov tseem ceeb rau kev ua tau zoo thiab kev nyab xeeb.

Tsis yog LFP (Lithium Iron Phosphate) lossis NMC (Nickel Manganese Cobalt) yog universally "zoo dua." Qhov kev xaiv zoo tshaj plaws yog nyob ntawm daim ntawv thov tshwj xeeb qhov tseem ceeb. LFP ua tau zoo hauv kev nyab xeeb thiab lub neej voj voog, thaum NMC muaj zog dua qhov ceev.

LFP vs. NMC: Kev sib piv kom ntxaws rau cov kws ua haujlwm

Cov thawj coj khoom lag luam thiab cov kws tsim khoom xav tau kev nkag siab zoo ntawm ob qho kev ua lithium-ion chemistry:

NMC, nrog rau nws lub zog ntau dua, muab ntau dua rau cov tsheb hluav taws xob thiab lub zog ntau dua rau cov khoom siv nqa tau yooj yim, tab sis yuav tsum tau ntsuas kev nyab xeeb dua.

Lub txee lub neej ntawm lithium thawj roj teeb yog dab tsi?

Tsim rau cov cuab yeej siv tsis tu ncua tab sis xav tau kev ntseeg ntev ntev? Los yog xav txog kev khaws cia ntev ntev ntawm cov roj teeb? Lub neej txee yog qhov tseem ceeb.

Cov roj teeb lithium tseem ceeb muaj lub neej ntev tshwj xeeb, feem ntau yog li ntawm 10 mus rau 20 xyoo, nyob ntawm qhov tshwj xeeb chemistry thiab khaws cia. Qhov no yog qhov ntev dua li lwm hom roj teeb tseem ceeb xws li alkaline lossis zinc-carbon.

Cov yam ntxwv cuam tshuam rau txee lub neej thiab cov kev coj ua zoo tshaj plaws

Thaum zoo siab, lub txee lub neej ntawm thawj lub roj teeb lithium yog cuam tshuam los ntawm ntau yam:

• Chemistry: Cov tshuaj lithium sib txawv (piv txwv li, Li-MnO2, Li-SOCl2, Li-FeS2) muaj qhov sib txawv ntawm tus kheej tso tawm. Li-SOCl2 feem ntau khav theeb lub neej ntev tshaj plaws.
• Manufacturing Quality: Cov roj teeb zoo dua los ntawm cov tuam txhab muaj npe nrov xws li HJBP Lub Hwj Chim yuav muaj cov ntsaws ruaj ruaj zoo dua thiab cov ntaub ntawv ntshiab, txo qis kev cuam tshuam sab hauv uas ua rau nws tus kheej tawm.
• Cia Kub: Qhov ntsuas kub qis dua ua rau qeeb cov tshuaj lom neeg uas ua rau nws tus kheej tso tawm. Qhov zoo tshaj plaws cia yog txias, qhuav, thiab deb ntawm tshav ntuj ncaj qha. Lub tub yees (tsis yog khov) tuaj yeem txuas ntxiv txee lub neej, tab sis zam kom tsis txhob muaj dej thaum tshem tawm.
• av noo: Cov av noo siab tuaj yeem ua kom corrosion thiab degradation. Khaws cov roj teeb hauv qhov chaw qhuav.
• Initial State of Charge: Cov roj teeb uas khaws cia ntawm lub xeev qis me ntsis (tsis tau tso tawm tag nrho) feem ntau pom zoo rau lub sijhawm ntev.

Rau cov kws tsim khoom thiab cov neeg tswj xyuas cov khoom, qhia txog cov xwm txheej khaws cia thiab xaiv cov khoom muaj npe nrov xws li HJBP Power, nrog rau 15 xyoo ntawm kev paub, yog qhov tseem ceeb rau kev ua kom lub neej ntev tshaj plaws thiab ua kom muaj kev ntseeg siab ntev ntawm cov roj teeb lithium. Ib daim ntawv qhia los ntawm peb yuav muab cov lus pom zoo tshwj xeeb.
