Hauv cov roj teeb hluav taws xob tshiab, qhov zoo electrode ntawm lithium roj teeb yog ua los ntawm txhuas ntawv ci, thiab qhov tsis zoo electrode yog ua los ntawm tooj liab ntawv ci. Qhov zoo thiab tsis zoo electrodes ntawm sodium roj teeb yog ua los ntawm txhuas ntawv ci.
Vim hais tias qhov loj ntawm lub lattice octahedral voids ntawm cov hlau txhuas zoo ib yam li Li, nws yog ib qho yooj yim los tsim cov hlau sib txuas nrog Li. Li thiab Al tsis tsuas yog tsim cov hlau nrog cov tshuaj formula LiAl, tab sis kuj tuaj yeem tsim Li3Al2 lossis Li4Al3. Vim tias muaj kev ua haujlwm siab ntawm cov tshuaj tiv thaiv ntawm cov hlau Al thiab Li, hlau Al siv ntau npaum li cas ntawm Li, thiab nws cov qauv thiab cov duab kuj raug rhuav tshem, yog li nws tsis tuaj yeem siv los ua cov khoom siv tam sim no rau qhov tsis zoo electrode ntawm lithium-ion. roj teeb;
Cu tsuas muaj lub peev xwm me me lithium ntxig thaum lub sijhawm them roj teeb thiab cov txheej txheem tawm, thiab tswj cov qauv ruaj khov thiab cov khoom siv hluav taws xob, thiab tuaj yeem siv los ua cov khoom siv tam sim no rau cov khoom tsis zoo ntawm cov roj teeb lithium ion; ntawm 3.75V, lub polarization tam sim no ntawm Cu ntawv ci pib ua qhov tseem ceeb. Lub polarization tam sim no nce thiab nce nyob rau hauv ib txoj kab ncaj nraim, thiab oxidation intensifies, qhia tias Cu yuav tsis ruaj tsis khov ntawm lub peev xwm no; thaum lub polarization tam sim no ntawm cov ntawv txhuas yog me me thiab tas mus li thoob plaws hauv polarization muaj peev xwm ntau yam, thiab tsis muaj qhov pom tseeb corrosion tshwm sim, tswj kev ruaj ntseg ntawm electrochemical kev ua tau zoo. Txij li Al muaj lub peev xwm me me lithium tso rau hauv qhov zoo electrode muaj peev xwm ntau ntawm lithium-ion roj teeb thiab tuaj yeem tswj tau electrochemical stability, nws yog qhov tsim nyog raws li cov khoom siv electrode tam sim no rau cov roj teeb lithium-ion.
Tsis zoo li lithium, txij li txhuas thiab sodium tsis raug kev cuam tshuam kev sib txuam ntawm qhov tsis tshua muaj peev xwm, pheej yig txhuas ntawv ci tuaj yeem siv rau ob qho tib si zoo thiab tsis zoo electrodes ntawm sodium roj teeb es tsis txhob siv cov ntawv ci tooj liab kim dua.
Lithium aluminium ntawv ci yog cov khoom siv tseem ceeb rau qhov zoo electrode ntawm lithium roj teeb. Hauv cov roj teeb lithium-ion, aluminium ntawv ci yog cov khoom siv dav siv cathode tam sim no. Nws tsis tsuas yog ua haujlwm rau cov khoom siv cathode nquag, tab sis kuj tuaj yeem sau cov khoom siv tam sim no los ntawm lub roj teeb cathode active khoom thiab coj mus rau sab nraud Circuit Court, yog li paub txog cov txheej txheem ntawm kev hloov tshuaj lom neeg rau hauv hluav taws xob hluav taws xob.
Lithium roj teeb txhuas ntawv nyiaj muaj cov kev xav tau ntau dua hauv txhua yam, thiab ultra-thin thiab siab zog yog yav tom ntej qauv. Raws li lub zog ntom ntom ntawm cov roj teeb lub zog nce, qhov yuav tsum tau ua rau aluminium foil thickness uniformity, kev sib txuas ua haujlwm, conductivity, nto nro, elongation thiab lwm yam ntsuas kuj zoo li siab dua.
