Li-ion roj teeb

by kim Kho tshiab: Lub Xya hli ntuj 9, 2022

Li-ion roj teeb yog cov roj teeb uas muaj roj teeb uas muaj lithium ions. Lawv siv nyob rau hauv txhua yam ntawm cov xov tooj ntawm tes mus rau lub tsheb. Tab sis lawv ua haujlwm li cas?

Li-ion roj teeb siv cov txheej txheem intercalation los khaws lub zog. Cov txheej txheem no suav nrog lithium ions txav ntawm cathode thiab anode hauv lub roj teeb. Thaum twg them nyiaj, cov ions txav ntawm lub anode mus rau cathode, thiab thaum tso tawm, lawv txav mus rau qhov sib txawv.

Tab sis qhov ntawd tsuas yog ib lub ntsiab lus luv luv xwb. Cia peb saib txhua yam hauv kev nthuav dav ntxiv.

Lithium-ion roj teeb yog dab tsi?

Lithium-ion roj teeb muaj nyob txhua qhov chaw niaj hnub no! Lawv siv peb lub xov tooj, laptops, hluav taws xob tsheb, thiab lwm yam. Tab sis lawv yog dab tsi? Cia wb mus saib ntxiv!

tsim

Cov roj teeb lithium-ion yog tsim los ntawm ib lossis ntau lub hlwb, lub rooj tsav xwm tiv thaiv, thiab ob peb lwm yam khoom:

• Electrodes: Qhov zoo thiab tsis zoo them kawg ntawm lub xov tooj ntawm tes. Txuas nrog rau cov khoom siv tam sim no.
• Anode: Qhov tsis zoo electrode.
• Electrolyte: Cov kua los yog gel uas ua hluav taws xob.
• Cov khoom siv tam sim no: Cov khoom siv hluav taws xob ntawm txhua lub electrode ntawm lub roj teeb uas txuas nrog lub terminals ntawm lub xov tooj ntawm tes. Cov terminals no xa cov hluav taws xob tam sim no ntawm lub roj teeb, lub cuab yeej, thiab lub zog hluav taws xob uas ua rau lub roj teeb.
• Separator: Ib zaj duab xis porous uas cais cov electrodes thaum ua kom muaj kev sib pauv ntawm lithium ions ntawm ib sab mus rau lwm qhov.

Yuav ua li cas nws hauj lwm

Thaum koj siv lub cuab yeej siv los ntawm lub roj teeb lithium-ion, lithium ions txav mus rau hauv lub roj teeb ntawm lub anode thiab cathode. Nyob rau tib lub sijhawm, cov khoom siv hluav taws xob tau txav mus rau hauv lub voj voog sab nraud. Qhov kev txav ntawm ions thiab electrons no yog qhov tsim cov hluav taws xob tam sim no uas ua rau koj lub cuab yeej muaj zog.

Thaum lub roj teeb tso tawm, lub anode tso tawm lithium ions mus rau cathode, tsim cov dej ntws ntawm electrons uas pab txhawb koj lub zog. Thaum lub roj teeb them, qhov rov qab tshwm sim: lithium ions raug tso tawm los ntawm cathode thiab tau txais los ntawm anode.

Koj tuaj yeem nrhiav tau lawv nyob qhov twg?

Lithium-ion roj teeb muaj nyob txhua qhov chaw niaj hnub no! Koj tuaj yeem pom lawv hauv xov tooj, laptops, tsheb fais fab, thiab lwm yam. Yog li lwm zaus koj siv ib qho ntawm koj cov khoom nyiam, tsuas yog nco ntsoov tias nws tau siv los ntawm lithium-ion roj teeb!

Lub Fascinating Keeb Kwm ntawm Lithium-Ion Roj Teeb

Thiab cia peb tsis txhob hnov ​​​​qab txog xov tooj cua tswj cov qauv, qauv dav hlau, thiab txawm tias Mars Curiosity rover!

telecommunications

Cov roj teeb lithium-ion kuj tseem siv los ua lub zog thaub qab hauv kev sib txuas lus. Ntxiv rau, lawv tab tom tham txog qhov kev xaiv muaj peev xwm rau daim phiaj hluav taws xob cia, txawm hais tias lawv tsis tshua muaj nqi sib tw.

Yam Koj Yuav Tsum Paub Txog Lithium-Ion Battery Performance

Zog ceev

Thaum nws los txog rau cov roj teeb lithium-ion, koj tab tom saib qee lub zog hnyav! Peb hais 100-250 W·h/kg (360-900 kJ/kg) thiab 250-680 W·h/L (900-2230 J/cm3). Qhov ntawd yog lub zog txaus los teeb lub nroog me me!

voltage

Cov roj teeb lithium-ion muaj qhov qhib hluav taws xob ntau dua li lwm hom roj teeb, xws li lead-acid, nickel-hlau hydride, thiab nickel-cadmium.

Sab Hauv

Internal kuj nce nrog ob qho tib si caij tsheb kauj vab thiab hnub nyoog, tab sis qhov no nyob ntawm qhov hluav taws xob thiab qhov kub thiab txias cov roj teeb khaws cia ntawm. Qhov no txhais tau hais tias qhov voltage ntawm lub terminals poob rau hauv load, txo qhov siab tshaj plaws tam sim no kos.

Them Lub sij hawm

Ploj mus yog cov hnub thaum cov roj teeb lithium-ion siv ob teev lossis ntau dua los them. Tam sim no, koj tuaj yeem tau txais kev them tag nrho hauv 45 feeb lossis tsawg dua! Hauv 2015, cov kws tshawb fawb txawm pom tias muaj peev xwm 600 mAh roj teeb them rau 68 feem pua ​​​​muaj peev xwm hauv ob feeb thiab 3,000 mAh roj teeb them rau 48 feem pua ​​​​muaj peev xwm hauv tsib feeb.

Tus nqi txo

Cov roj teeb lithium-ion tau los ntev txij li xyoo 1991. Cov nqi tau nqis 97% thiab lub zog ceev tau ntau dua peb npaug. Cov hlwb sib txawv nrog tib chemistry tuaj yeem muaj qhov sib txawv ntawm lub zog, yog li koj tuaj yeem tau txais ntau dua rau koj cov nyiaj npib.

Dab tsi yog Deal nrog Lithium-Ion Battery Lifespan?

tsim

Thaum nws los txog rau lithium-ion roj teeb, lub neej feem ntau yog ntsuas raws li tus naj npawb ntawm cov nqi them tag nrho nws yuav siv sij hawm kom ncav cuag qhov pib. Qhov chaw pib no feem ntau txhais tau hais tias muaj peev xwm poob lossis nce impedance. Cov neeg tsim khoom feem ntau siv lo lus "lub neej voj voog" los piav txog lub neej ntawm lub roj teeb ntawm cov voj voog uas nws yuav siv mus txog 80% ntawm nws cov peev txheej.

Khaws cov roj teeb lithium-ion nyob rau hauv lub xeev them kuj txo lawv lub peev xwm thiab ua rau kom cov cell tsis kam. Qhov no feem ntau yog vim qhov kev loj hlob tsis tu ncua ntawm cov khoom electrolyte interface ntawm lub anode. Tag nrho lub neej voj voog ntawm lub roj teeb, suav nrog ob lub voj voog thiab kev ua haujlwm tsis ua haujlwm, raug xa mus rau lub neej daim ntawv qhia hnub.

Tej yam cuam tshuam rau lub roj teeb voj voog lub neej

Lub voj voog lub neej ntawm lub roj teeb raug cuam tshuam los ntawm ntau yam, xws li:

• Kub
• Tshem tawm tam sim no
• Them tam sim no
• State of charge ranges (qhov tob ntawm kev tso tawm)

Hauv kev siv lub ntiaj teb tiag tiag, xws li smartphones, laptops thiab tsheb fais fab, roj teeb tsis tas yuav them tag nrho thiab tawm mus. Qhov no yog vim li cas kev txhais cov roj teeb lub neej nyob rau hauv cov nqe lus ntawm tag nrho cov tawm mus yuav ua tau yuam kev. Txhawm rau kom tsis txhob muaj qhov tsis meej pem no, cov kws tshawb fawb qee zaum siv cov paug tawm, uas yog tag nrho cov nqi them (Ah) xa los ntawm lub roj teeb thaum nws lub neej tag nrho lossis sib npaug tag nrho.

Roj teeb Degradation

Cov roj teeb qis qis dua lawv lub neej, ua rau muaj peev xwm txo qis thiab, qee zaum, kev ua haujlwm qis ntawm tes. Qhov no yog vim muaj ntau yam tshuaj lom neeg thiab kev hloov pauv ntawm cov electrodes. Kev degradation yog qhov kub thiab txias, thiab cov nqi them siab kuj tseem ua rau muaj peev xwm poob.

Qee cov txheej txheem degradation feem ntau suav nrog:

• Kev txo qis ntawm cov organic carbonate electrolyte ntawm lub anode, uas ua rau kev loj hlob ntawm Solid Electrolyte Interface (SEI). Qhov no ua rau muaj kev nce hauv ohmic impedance thiab txo qis hauv kev them nqi hluav taws xob Ah.

• Lithium hlau plating, uas kuj ua rau poob ntawm lithium cov khoom muag (cyclable Ah charge) thiab sab hauv luv-circuiting.

• Kev poob ntawm cov khoom siv hluav taws xob (tsis zoo los yog zoo) vim kev tawg, tawg, exfoliation, detachment los yog hloov pauv ntim tsis tu ncua thaum caij tsheb kauj vab. Qhov no qhia tau hais tias yog ob qho tib si them thiab lub zog ploj (nce ntxiv).

• Corrosion / dissolution ntawm qhov tsis zoo tooj liab tam sim no collector ntawm tsawg cell voltages.

• Degradation ntawm PVDF binder, uas tuaj yeem ua rau cov khoom siv electroactive.

Yog li, yog tias koj tab tom nrhiav lub roj teeb uas yuav kav ntev, nco ntsoov khaws lub qhov muag ntawm txhua yam uas tuaj yeem cuam tshuam rau nws lub neej voj voog!

Kev phom sij ntawm Lithium-ion roj teeb

Lithium-ion roj teeb yog dab tsi?

Cov roj teeb lithium-ion yog lub zog ntawm peb lub ntiaj teb niaj hnub no. Lawv pom nyob rau hauv txhua yam ntawm smartphones mus rau hluav taws xob tsheb. Tab sis, zoo li txhua yam muaj zog, lawv tuaj nrog ob peb yam txaus ntshai.

Dab Tsi Yuav Ua Dab Tsi?

Cov roj teeb lithium-ion muaj cov nplaim hluav taws xob hluav taws xob thiab tuaj yeem ua kom muaj zog yog tias puas. Qhov no txhais tau tias yog tias lub roj teeb tau them sai dhau, nws tuaj yeem ua rau luv luv thiab ua rau tawg thiab hluav taws kub.

Nov yog qee yam ntawm cov roj teeb lithium-ion tuaj yeem ua rau muaj kev phom sij:
