Kev tawm tus kheej hauv cov roj teeb lithium-ion hais txog qhov kev ua kom muaj roj teeb /}}}}}}} lithium-ion roj teeb nthuav qhia tus kheej txo tus kheej qis tab sis tseem cuam tshuam . cov laj thawj ua tau raws li hauv qab no:
{{01. tsis muaj cov tshuaj sab nraud (kev tawm tus kheej)
(1) SEI txheej kev loj hlob thiab kev sib cuam tshuam:
Anode (feem ntau graphite) yog coated nrog cov khoom siv hluav taws xob ruaj khov, tshwj xeeb} Txawm li cas los xij, nws tsis zoo rau kev siv roj teeb ions thiab electrolyte, ua rau muaj peev xwm poob thiab voltage poob-ib tug loj pab rau tus kheej-tawm .
(2) Kev daws teeb meem kev daws teeb meem / txo:
Them cov ntaub ntawv cathode (e {{{{0} g}}}}}} pa taws los ntawm oxidation thaum nyob rau lub sijhawm ntev Cathode . Zoo sib xws, ntawm Ande cov kev tiv thaiv, txawm muaj peev xwm ploj mus .
(3) Cov khoom txawv txawv:
Trace impurities (e {{{{0} g}}}}}}}}}} Kuv tuaj yeem tsim cov kev tsis txaus siab, siv sijhawm rau kev them nyiaj
{{02.} kev voj voog micro luv-luv (tshwm sim los ntawm kev tsim khoom lossis kev laus)
(1) Separator tsis xws luag:
Cov pinholes me me, impurities, los yog tsis muaj zog rau hauv tus neeg siv hluav taws xob (micros ec electrolyte.
(2) dendrite penetration:
Lithium Dendrites yuav tsim tsis ncaj rau ntawm Anode vim muaj kev sib tw, lossis kev laus} Cov pob hluav taws xob muaj peev xwm nkag mus rau hauv cov hluav taws xob thiab ua rau muaj kev luv luv.
(3) Cov plua plav tsis huv:
Residual Hlau Plua Plav (E .}} Txawm li cas los xij, tsis muaj plua plav tsis muaj zog, tuaj yeem ua rau lub ntsej muag tsis zoo Zoo solterator daws teeb meem, saib pebRoj Teeb Cov Khoom Siv Lawm.
3. kub nyhav
Kub yog qhov tseem ceeb tshaj plaws . kev ua kom nrawm dua, tsis txhob muaj kev cuam tshuam rau kev ua kom ntev dua tshiab (tsis txhob muaj roj ntsha kom sov {{4
4. cuam tshuam ntawm kev tawm ntawm tus kheej
• Tsis muaj peev xwm poob: txo cov peev txheej siv tau .
• Volfage poob: Txo cov voltict-Circuit Court (OCV) dhau lub sijhawm .
• Cov kev laus sai sai: cov kev tshwm sim sab (e {{{}}} g}, electrolyte, nrawm .
• SM kev kwv yees cov nyom: Kev tawm tsam tus kheej ua rau kev kwv yees lub xeev "(soc) kwv yees ntawm voltage {}}
• Cov kev phom sij kev nyab xeeb: cov roj ntsha siv hluav taws xob hnyav tuaj yeem ua rau cua sov lossis thermal khiav tawm .
5. Kev Ua Tswv Yim
(1) Tsim Txhim Kho Zoo & Cov Khoom Siv:
Txhim kho sei stability, tsim cov oxidation-resistant electrolytes, thiab txhim kho cov khoom siv roj teeb zoo rau cov kev daws teeb meem {}}
(2) Tswj Chaw Cia Khoom:
• Kub: Khaws rau ntawm 10 Degree -25 Qib (zam<0°C).
• SOC: tswj 40% -60 -60%% soc rau lub sijhawm ntev . puv puv electrolyte oxidation; Kev rho tawm kev pheej hmoo ntawm kev pheej hmoo anode kev puas tsuaj .
(3) Lub sijhawm them nyiaj:
Rau cov roj teeb tsis txawj, SOF thiab recharge rau ~ 50% thaum tsawg kom tiv thaiv kev tawm paug .
(4) Kev Tsim nruj nruj:
Txo qhov tsis txaus siab impurities / hlau hmoov av thiab ua kom muaj kev sib cais ncaj ncees . pebCov roj teeb khoom sivmuab cov ntaub ntawv siab tshaj los txo cov kev pheej hmoo pheej hmoo .
Tag
Kev tawm tus kheej rau hauv cov roj teeb uas muaj cov roj ntsha tsis txaus ntseeg kev tsim tawm thiab R & D cov kev daws teeb meem-los ntawm cov khoom siv rau cov khoom siv-leverage rau peb cov kws tshaj lij ntawmTob Lub Zog Tshiab.
