Taw qhia:
Cov roj teeb tuaj yeem muab faib ua peb pawg: roj teeb tshuaj, roj teeb lub cev thiab roj ntsha roj ntsha. Cov roj teeb tshuaj lom neeg yog siv dav hauv tsheb fais fab.
Chemical Battery: Lub roj teeb tshuaj yog ib yam khoom siv uas hloov cov hluav taws xob hluav taws xob rau hauv hluav taws xob los ntawm kev siv tshuaj lom neeg. Nws muaj qhov zoo thiab tsis zoo electrodes thiab electrolytes.
Lub roj teeb lub cev: Lub roj teeb lub cev hloov lub zog lub cev (xws li lub hnub ci zog thiab lub zog siv tshuab) rau hauv hluav taws xob los ntawm kev hloov lub cev.
Kev faib cov roj teeb tshuaj lom neeg: Los ntawm cov qauv kev pom, nws tuaj yeem muab faib ua ob pawg: cov roj teeb cia (xws li cov roj teeb thawj thiab cov roj teeb thib ob) thiab roj hlwb. Cov roj teeb tseem ceeb: tsuas yog siv tau ib zaug xwb, cov khoom siv ua haujlwm tsis tuaj yeem thim rov qab, kev tso tawm tus kheej me me, qhov kev tiv thaiv sab hauv yog loj, thiab cov peev txheej tshwj xeeb thiab ntim tshwj xeeb muaj peev xwm siab.
Cov roj teeb thib ob: tuaj yeem them thiab tawm ntau zaus, cov khoom siv rov qab tau, thiab tau siv dav hauv ntau yam khoom siv them nyiaj. Feem ntau ntawm cov qauv ntawm kev ua lag luam tam sim no siv cov roj teeb uas siv tau thib ob los tsav lub tsheb. Cov roj teeb thib ob tau muab faib ua cov roj teeb lead-acid, cov roj teeb nickel-cadmium, cov roj teeb nickel-hlau hydride thiab lithium roj teeb raws li cov khoom siv electrode sib txawv. Tam sim no, cov tuam txhab tsheb hauv kev lag luam feem ntau sivlithium roj teeb, thiab ob peb siv nickel-hlau hydride roj teeb.
Lub ntsiab lus ntawm lithium roj teeb
Lithium roj teebyog lub roj teeb uas siv lithium hlau los yog lithium alloy ua cov khoom zoo lossis tsis zoo electrode thiab cov tshuaj tsis muaj dej electrolyte.
Cov txheej txheem them thiab tso tawm ntawm lithium roj teeb feem ntau yog nyob ntawm kev txav ntawm lithium ions (Li +) ntawm qhov zoo thiab tsis zoo electrodes. Thaum them nyiaj, lithium ions yog deintercalated los ntawm qhov zoo electrode thiab embedded rau hauv qhov tsis zoo electrode los ntawm electrolyte, thiab cov electrode tsis zoo nyob rau hauv ib tug lithium-nplua nuj lub xeev; qhov opposite yog muaj tseeb thaum tso tawm.
Electrochemical txoj cai ntawm lithium-ion roj teeb
Cov tshuaj tiv thaiv electrode zoo: LiCoO2 → Li1-xCoO2 + xLi + + xe-
Cov tshuaj tiv thaiv tsis zoo electrode: C + xLi + + xe- → CLix
Lithium-ion roj teeb muaj lub zog siab, lub neej ntev thiab siv tus kheej qis, thiab yog siv dav hauv lub xov tooj ntawm tes, khoos phis tawm thiab cov tsheb hluav taws xob.
Daim ntawv thov teb ntawmlithium roj teebfeem ntau muab faib ua hwj chim thiab tsis muaj hwj chim. Lub zog hluav taws xob ntawm kev siv roj teeb lithium-ion suav nrog lub tsheb hluav taws xob, cov cuab yeej hluav taws xob, thiab lwm yam .; Cov chaw tsis muaj hluav taws xob suav nrog cov khoom siv hluav taws xob thiab khoom siv hluav taws xob, thiab lwm yam.
Kev sib xyaw thiab kev faib tawm ntawm cov roj teeb lithium
Cov roj teeb lithium feem ntau yog tsim los ntawm plaub ntu: cov khoom zoo electrode, cov khoom tsis zoo electrode, electrolytes thiab roj teeb cais. Cov ntaub ntawv tsis zoo electrode feem ntau cuam tshuam rau kev ua haujlwm pib thiab kev ua haujlwm ntawm cov roj teeb lithium-ion. Lithium roj teeb tsis zoo electrodes feem ntau muab faib ua ob pawg: cov khoom siv carbon thiab cov khoom tsis yog carbon. Daim ntawv thov kev lag luam feem ntau yog cov khoom siv hluav taws xob tsis zoo graphite ntawm cov ntaub ntawv carbon, cov khoom siv graphite thiab ntuj graphite muaj cov ntawv thov loj. Silicon-raws li tsis zoo electrodes yog lub hom phiaj ntawm kev tshawb fawb los ntawm cov tuam txhab loj tsis zoo electrode thiab yog ib qho ntawm cov khoom siv tsis zoo electrode tshiab uas feem ntau yuav raug siv rau hauv cov nplai loj yav tom ntej.
Lithium roj teebtau muab faib ua lithium cobalt oxide roj teeb, lithium hlau phosphate roj teeb, roj teeb ternary, thiab lwm yam raws li cov khoom siv electrode zoo;
Raws li cov khoom siv, lawv muab faib ua cov roj teeb square, roj teeb cylindrical thiab cov roj teeb muag muag;
Raws li daim ntawv thov scenarios, lawv tuaj yeem muab faib ua cov khoom siv hluav taws xob, lub zog cia thiab cov roj teeb hluav taws xob. Ntawm lawv, cov neeg siv khoom siv roj teeb lithium feem ntau yog siv hauv 3C cov khoom; Lub zog cia roj teeb feem ntau yog siv rau hauv tsev neeg lub zog khaws cia thiab faib cov khoom siv hluav taws xob ywj pheej ntawm lub zog cia xws li hnub ci zog thiab cua tsim hluav taws xob; cov roj teeb hluav taws xob feem ntau yog siv hauv ntau lub tsheb hluav taws xob, cov cuab yeej hluav taws xob thiab lub zog tshiab tsheb.
