Cov muaj pes tsawg leeg ntawmlithium roj teeb

Cov khoom siv ntawm cov roj teeb lithium feem ntau suav nrog cov khoom siv hluav taws xob zoo, cov khoom siv tsis zoo electrode, cov khoom sib cais, electrolytes, thiab casings.

1. Ntawm cov khoom siv hluav taws xob zoo, cov khoom siv feem ntau yog lithium cobaltate, lithium manganate, lithium hlau phosphate thiab ternary cov ntaub ntawv (polymers ntawm nickel, cobalt thiab manganese).Cov khoom siv electrode zoo suav rau qhov loj (qhov loj ntawm qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob yog 3: 1 ~ 4: 1), vim tias qhov ua tau zoo ntawm cov khoom siv electrode ncaj qha cuam tshuam rau kev ua haujlwm ntawm lithium-ion roj teeb, thiab nws tus nqi kuj ncaj qha txiav txim tus nqi ntawm lub roj teeb.
2. Ntawm cov ntaub ntawv tsis zoo electrode, ntuj graphite thiab dag graphite yog tam sim no cov ntaub ntawv tsis zoo electrode.Cov khoom siv anode tau tshawb pom muaj xws li nitrides, polyaspartic acid, tin-based oxides, tin alloys, nano-anode cov ntaub ntawv, thiab lwm yam intermetallic compounds.Raws li ib qho ntawm plaub cov ntaub ntawv tseem ceeb ntawm cov roj teeb lithium, cov ntaub ntawv tsis zoo electrode ua lub luag haujlwm tseem ceeb hauv kev txhim kho roj teeb muaj peev xwm thiab kev ua haujlwm ntawm lub voj voog, thiab yog nyob rau hauv lub hauv paus ntawm nruab nrab mus txog ntawm lithium roj teeb kev lag luam.
3. Kev lag luam-taw qhia cov ntaub ntawv diaphragm feem ntau yog polyolefin diaphragms, uas yog tsim los ntawm polyethylene thiab polypropylene.Nyob rau hauv cov qauv ntawm lithium roj teeb separator, lub separator yog ib qho tseem ceeb hauv cov khoom.Qhov kev ua tau zoo ntawm cov khoom sib cais txiav txim siab cov qauv kev sib txuas thiab kev ua haujlwm sab hauv ntawm lub roj teeb, uas cuam tshuam ncaj qha rau lub peev xwm, lub voj voog thiab kev nyab xeeb ntawm lub roj teeb.Ib qho kev sib cais nrog kev ua tau zoo heev ua lub luag haujlwm tseem ceeb hauv kev txhim kho tag nrho cov kev ua haujlwm ntawm lub roj teeb.
4. Cov electrolyte feem ntau yog ua los ntawm high-purity organic solvents, electrolyte lithium ntsev, tsim nyog additives thiab lwm yam raw cov ntaub ntawv nyob rau hauv ib tug tej yam kev faib ua feem nyob rau hauv tej yam kev mob.Lub electrolyte plays lub luag hauj lwm ntawm kev ua ions ntawm qhov zoo thiab tsis zoo electrodes ntawm lithium roj teeb, uas yog guaranteed ntawm high voltage thiab siab tshwj xeeb zog ntawm lithium ion roj teeb.
5. Roj teeb casing: muab faib ua steel casing, txhuas casing, npib tsib xee-plated hlau casing (rau cylindrical roj teeb), aluminium-yas zaj duab xis (mos ntim), thiab lwm yam., raws li zoo raws li lub roj teeb cap, uas kuj yog qhov zoo thiab tsis zoo terminals ntawm lub roj teeb
6. Lub hauv paus ntsiab lus ntawm Roj teeb ua haujlwm
7. Thaum lub roj teeb raug them, lithium ions raug tsim los ntawm qhov zoo electrode ntawm lub roj teeb, thiab cov lithium ions generated txav mus rau qhov tsis zoo electrode los ntawm electrolyte.Cov qauv carbon ntawm qhov tsis zoo electrode muaj ntau qhov pores, thiab lithium ions mus txog qhov tsis zoo electrode yog embedded rau hauv micropores ntawm cov pa roj carbon txheej.Qhov ntau lithium ions yog embedded, lub peev xwm ntau dua yuav yog.Thaum lub roj teeb tawm, cov lithium ions embedded nyob rau hauv cov pa roj carbon txheej ntawm cov electrode tsis zoo tawm thiab rov qab mus rau qhov zoo electrode.Qhov ntau lithium ions rov qab mus rau qhov zoo electrode, lub peev xwm tawm ntau dua.Feem ntau hais lus, lub peev xwm tawm mus yog hais txog qhov muaj peev xwm tawm.Thaum lub sijhawm them thiab tawm ntawm lub roj teeb lithium, lithium ions nyob rau hauv lub xeev ntawm kev txav los ntawm qhov zoo electrode mus rau qhov tsis zoo electrode.Yog hais tias cov duab ntawm lub lithium roj teeb yog piv rau lub rooj zaum rocking, ob qhov kawg ntawm lub rooj zaum rocking yog qhov zoo thiab tsis zoo electrodes ntawm lub roj teeb, thiab lithium ions zoo li cov neeg ncaws pob, khiav rov qab los ntawm ob kawg ntawm lub rooj zaum rocking. .Yog li ntawd, cov roj teeb lithium tseem hu ua rocking chair batteries.
