Cov roj teeb kua qaub vs lithium roj teeb

‌1. Core Core Cov Khoom Siv:‌

‌Lead - kua qaub (lab):Siv cov hmoov txhuas (PB) thiab Lead Dioxide (PBO₂) Electrodes submerged nyob rau hauv ib qho kua sulfuric acid (hssay₄) electrolyte. Cov kev tawm tsam muaj kev hloov pauv cov kab ke los ua cov sulfate thaum tso tawm, thiab thim rov qab rau qhov no.

‌Lithium {{0} ion ion (lib):Siv cov lithium sib txuas (piv txwv li, lithium cobalval oxide- lithy} lith cov ntaub ntawv) raws li anode, thiab cov roj ntsha suab, thiab cov ntsev lithium nyob rau hauv ib tug organic huab cua yog cov electrolyte. Lithium ions (l⁺) shuttle ntawm cathode thiab anode thaum them / tawm.

2‌. Zog ntom (wh / kg lossis wh / l):‌

‌Lab:Tsawg zog hluav taws xob ntom ntom (feem ntau 30-50 wh / kg). Lawv hnyav thiab loj heev rau cov nyiaj uas lawv khaws cia.

‌Lib:Tseem ceeb dua lub zog hluav taws xob ntom ntom (feem ntau 100-265+ Wh / Kg). Ntau ntau sib dua thiab ntau dua kev sib xyaw rau tib lub zog cia khoom. Qhov no yog qhov tseem ceeb rau cov khoom siv hluav taws xob Portable thiab cov tsheb hluav taws xob.

‌3. Fais fab ntom (W / kg):‌

‌Lab:Feem ntau muab cov lim piam luv luv- lub zog surge zog (tshwj xeeb tshaj yog cov roj teeb uas pib nrawm dua rau lawv sai sai. Lub hwj chim tshwj xeeb yog ib nrab.

‌Lib:Feem ntau cov hwj huam tshwj xeeb, muaj peev xwm xa cov dej pheebsuab kom muaj txiaj ntsig zoo rau lub sijhawm ua tsaug ntau dua. Qee cov variants (zoo li LFP) Excel ntawm cov nqi siab.

‌4. Lub neej voj voog:‌

‌Lab:Lub sijhawm luv luv lub neej (feem ntau 200 - 500 mus txog rau 50-80% qhov tob ntawm paug - dod). Sib sib zog nqus tawm ho luv lub neej.

‌Lib:Tseem ceeb ntev dua lub neej (feem ntau {500-3000+ cms, hnyav nyob ntawm Chemistry, kub, thiab Dod tswj). Tuaj yeem zam kev tawm tsam kev tawm tsam ib ntus thaum ua kom muaj kev tswj hwm ntev (tshwj xeeb yog LFP Chemistry).

‌5. Efficiency:‌

‌Lab:QIS TXEE / Kev Tawm Kev Nyab Xeeb (feem ntau 70-85%). Lub zog ploj mus thaum cua sov thaum hloov dua siab tshiab.

‌Lib:Cov peev txheej siab dua (feem ntau 95-99% rau feem ntau cov kws kho mob). Lub zog me me yog nkim li cua sov.

‌6. Nqi:‌

‌Lab:Tsub nqi kuj maj mam ua piv rau lobs. Kev them nyiaj sai sai tuaj yeem ua rau overheating thiab kev puas tsuaj (gassing, phaj corrosion).

‌Lib:Feem ntau tuaj yeem lees txais cov nqi them nyiaj ntau dua li kev kuaj, tshwj xeeb nrog cov kev tswj roj teeb tsim nyog (BMS). Txawm li cas los xij, kev them nyiaj sai sai tuaj yeem cuam tshuam ntev -} kev noj qab haus huv.

‌7. Nqi:‌

‌Lab:Ho qis dua upfront nqi ib chav muaj peev xwm ($ / kWh).

‌Lib:Ntau dua upfront raug nqi ib chav muaj peev xwm (/kwage,thegapisowing oothgapithantower

8‌. Kev Txij Nkawm & Kev Nyab Xeeb:‌

‌Lab (dej nyab):Xav tau kev tu ncua (khij cov qib electrolyte, ntxiv cov dej distilled, cov nqi sib luag). Kev pheej hmoo ntawm cov kua qaub so kua qaub / nchuav. Tuaj yeem qhib cov roj hydrogen mydrogen thaum them (tawg txaus ntshai). Overcharging ua rau kev xeb thiab gassing.

‌Lab (vrla -} agm / gel):Txij Nkawm - dawb. Kaw tsim qauv minimizes zam kev pheej hmoo, tab sis thermal khiav tawm yog tseem muaj peev xwm nyob rau hauv kev tsim txom hnyav. Feem ntau muaj kev nyab xeeb dua li dej nyab tab sis tsis tshua muaj kev nyab xeeb dua li feem ntau lobs.

‌Lib:Feem ntau cov txij nkawm - dawb. Cov koog muaj kaw. Yuav tsum muaj cov roj teeb sib zog (BMS) rau kev ua haujlwm kom zoo (tshuaj xyuas voltage, ntsuas kub, tam sim no, xov tooj cua ntsuas). Kev pheej hmoo ntawm Thermal khiav tawm (hluav taws / tawg) Yog tias kev nyab xeeb ntau dua los ntawm Chemistry (LFP tau muaj kev nyab xeeb ntau dua NMC / LCO). Tsis muaj tshuaj lom cov kua qaub ua rau muaj kev phom sij.

9‌ Qhov hnyav & Loj:‌

‌Lab:Hnyav thiab loj rau lub zog khaws cia.

‌Lib:Ntais thiab kev sib txuas ntxiv rau kev sib piv hauv lub zog sib piv.

‌Kev ua haujlwm kub ntau:‌

‌Lab:Kev ua yeeb yam degrades ho nyob rau hauv kub txias (txo qhov muaj peev xwm, hwj chim). Kev kub siab kub ua kom muaj kev laus / corrosion. Kev ua haujlwm hnyav.

‌Lib:Feem ntau txias txias - huab cua huab cua kev ua tau zoo dua li lab (txawm tias tseem txo peev xwm). Kev kub siab sim ua kom muaj kev phom sij ntxiv thiab ua kom muaj kev phom sij kom txaus ntshai. Rhiab rau qhov kawg.

1‌0. Kev cuam tshuam ib puag ncig & kev siv hluav taws xob:‌

‌Lab:‌ High recycling rate (>98% nyob rau ntau thaj tsam). Lead yog tshuaj lom, xav tau nruj tuav thiab rov ua dua tshiab. Sulfuric acid yog corrosive. Tsim kho cov khoom siv rov ua dua tshiab.

‌Lib:Siv cov txheej txheem rov ua dua yog tsis tshua paub tab tab sis tab sis kev loj hlob sai vim muaj kev loj hlob. Muaj cov khoom tseem ceeb (lithium, cobalt, npib tsib xee) tab sis extraction zog {}}} ntso} intensive. Kev pheej hmoo phom sij nrog kev thauj mus los thiab rov ua dua tshiab. Tsawg dua kev phom sij lom zem tshaj cov kua qaub, tab sis kev cuam tshuam ib puag ncig los ntawm kev sib xyaw thiab kev ua tiav.

1‌1. Self - tso tawm tus nqi:‌

‌Lab:Nruab nrab tus kheej - tso tawm tus nqi (nyob ib ncig ntawm 3-5% ib hlis rau VRLA).

‌Lib:Tus kheej tsawg - kev coj tus nqi (feem ntau 1-3% ib hlis).

 

‌Ntsiab lus: Qhov twg xaiv?‌

‌Xaiv cov khoom noj - kua qaub (lab) thaum:‌

Tsawg heev upfront tus nqi yog thawj tsav tsheb.

Loj / luj tsis yog tsis tseem ceeb txwv.

Tam sim no muaj kev kub siab tam sim no (pib nias - di) yog xav tau.

Yooj yim them cov cuab yeej cuab tam tau yooj yim / yuav tsum tau ua.

Tsim tsa ua dua tshiab yog qhov tseem ceeb.

Cov Kev Siv: Tsheb / Tsheb / Lub Cev Muaj Zog Pib Roj Roj (UPS Backup

 

‌Xaiv lithium {{0} ion (lib) thaum:‌

Kev ceev hluav taws xob ntom (lub teeb yuag, kev sib xyaw loj) yog qhov tseem ceeb.

Kev xav tau ntev dua lub neej thiab muaj kev cuam tshuam ntxiv.

Kev ua haujlwm siab dua (tsis muaj zog siv zog) yog qhov tseem ceeb.

Kev them nyiaj sai yog qhov tsim nyog (nrog rau kev tsim kho vaj tse).

Txij Nkawm - Kev Ua Haujlwm Dawb yog qhov yuav tsum tau ua.

Cov ntawv thov: hluav taws xob tsheb (EVS), cov cuab yeej siv hluav taws xob (khoos phis tawj), cov khoom siv hluav taws xob rov qab), muaj drones hauv lub zog

Qhov kev xaiv thaum kawg yog nyob ntawm daim ntawv thov tshwj xeeb yog qhov tseem ceeb ntawm tus nqi, kev siv zog, kev siv zog, thiab ib puag ncig kev txiav txim siab.
