Dab tsi txiav txim qhov peev xwm ntawm lub roj teeb?
Apr 09, 2025
Roj teeb muaj peev xwm yog txiav txim siab los ntawm lub zog ntom thiab ntim, nrog lub zog ua kom ceev ua si lub luag haujlwm tseem ceeb. Roj teeb muaj peev xwm tseem ceeb muaj peev xwm khaws cov hluav taws xob hluav taws xob, suav raws li muaj peev xwm {0}} lub zog ntom × ntim; Lub zog ceev yog feem ntau txiav txim siab los ntawm cov khoom siv electrode zoo, thaum lub peev xwm tiag tiag kuj cuam tshuam los ntawm cov xwm txheej sab nraud xws li qhov kub thiab kev tawm tawm.
Tub ntxhais txiav txim siab yam
Cov khoom siv hluav taws xob tsis sib xws thiab ntim: roj teeb muaj peev xwm ua kom muaj hluav taws xob cia rau hauv cov khoom hluav taws xob lossis cov khoom siv hluav taws xob, thiab ntim ncaj qha cuam tshuam rau qhov chaw cia hluav taws xob.
Lub luag haujlwm tseem ceeb ntawm cov khoom siv hluav taws xob zoo: lub zog siv hluav taws xob feem ntau yog 273,83mah \/ g, uas cuam tshuam ncaj qha cuam tshuam rau cov kev txwv sab sauv ntawm theoretical muaj peev xwm.
Synergistic cuam tshuam ntawm cov khoom tsis zoo electrode thiab electrolytes muaj peev xwm cuam tshuam nrog kev siv hluav taws xob tsis ncaj ncees, thiab yog li cuam tshuam lub peev xwm tiag tiag.
Qhov sib txawv ntawm theoretical thiab lub peev xwm tiag tiag
Theoretical muaj peev xwm: suav los ntawm tag nrho cov nyiaj ntawm cov khoom siv zoo thiab tsis zoo. Piv txwv li, lub peev xwm theoretical ntawm 100g ntawm lithium cobalt oxide zoo electrode yog 27,383mAh (100g × 273.83mah \/ g).
Muaj peev xwm tiag tiag: raug rau kev siv cov ntaub ntawv uas siv tau, uas cuam tshuam los ntawm cov hauv qab no cov hauv qab no: Kev rho tawm tawm hauv qab no: Kev tshem tawm siab yuav ua rau muaj peev xwm muaj peev xwm muaj.
Kub: Tsawg tsawg kub txo qhov ceev ntawm ion tsiv teb tsaws thiab lub peev xwm txo qis (piv txwv li lub peev xwm yuav ua rau 50% ntawm qhov kub thiab txias).
Kev txiav tawm voltage: kev tawm tsam sib sib zog yuav ua kev puas tsuaj hluav taws xob thiab ua kom lub neej luv.
