Cov ntaub ntawv raw ntawm cov roj teeb lithium rechargeable feem ntau suav nrog cov hauv qab no:
1. Cov khoom siv electrode zoo
Cov khoom siv cathode yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hauv cov roj teeb lithium, uas txiav txim siab lub zog ceev thiab qhov hluav taws xob ntawm lub roj teeb. Cov khoom siv cathode feem ntau yog:
1, Lithium Cobaltate (LCO): Nws muaj lub peev xwm tshwj xeeb thiab kev ua haujlwm siab, tab sis tus nqi siab, thiab muaj qee yam teeb meem kev nyab xeeb thiab lub neej voj voog.
2, Lithium Manganate (LMO): Lub zog siab ceev, tab sis qhov kev ruaj ntseg yog qhov tsis zoo, yuav tsum tau ntxiv cov electrolyte ntau kom sib npaug rau sab hauv.
3, Lithium Iron Phosphate (LFP): Kev nyab xeeb siab thiab lub neej voj voog ntev, thiab cov khoom siv ntau, tus nqi qis, tab sis qis zog ceev, kev ua haujlwm kub tsis zoo.
4, Ternary Materials: Xws li lithium nickel cobalt manganese (NCM) thiab lithium nickel cobalt aluminate (NCA), kev sib xyaw ua ke ntawm qhov zoo ntawm ntau yam ntaub ntawv, nrog lub zog siab ceev, siab zog ceev thiab kev ua haujlwm zoo dua.
Nyob rau hauv lub realm ntawm lithium-ion roj teeb ntau lawm, AVEnergy excels nyob rau hauv lub manufacturing ntawm advanced cathode cov ntaub ntawv, nrog rau nws flagship muab yog ib tug high-kev ua tau zoo, high-zog-density ternary lithium-ion roj teeb cathode khoom.This ternary lithium cathode khoom yog feem ntau formulated los ntawm nickel (Ni), cobalt (Co), thiab manganese (Mn), los yog hloov nickel, cobalt, thiab txhuas (Al), nyob rau hauv meej ratios. Raws li nws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov qauv, nws nthuav tawm cov txiaj ntsig zoo hauv kev txhim kho lub zog tso zis, ua kom lub neej ntev, thiab ua kom zoo dua qub roj teeb kev ua tau zoo. Los ntawm kev tshawb fawb thiab kev loj hlob tsis tu ncua nrog rau kev ua kom zoo dua qub, Anwei mob siab rau xa cov khoom zoo tshaj plaws ternary lithium cathode. cov ntaub ntawv uas haum rau ntau yam kev xav tau ntawm kev ua lag luam thaum muab cov kev daws teeb meem zoo rau lub zog cia thiab ntau yam khoom siv hluav taws xob portable.
2. Cov khoom siv hluav taws xob tsis zoo
Cov ntaub ntawv tsis zoo electrode feem ntau yog xaiv los ntawm graphite lossis lwm yam khoom siv carbon, nrog rau silicon-based, tin-based thiab lwm yam ntaub ntawv tshiab. Ntawm lawv:
1, Graphite: nrog zoo lithium embedded kev ua tau zoo thiab conductivity, thiab tus nqi qis, nws yog tam sim no cov khoom siv dav siv anode. Txawm li cas los xij, muaj qhov teeb meem ntawm qhov tsis sib xws lithium ion infiltration.
2, Silicon-raws li cov ntaub ntawv: muaj peev xwm theoretical siab, tab sis ntsib teeb meem xws li ntim nthuav dav thiab lub voj voog ruaj khov hauv kev siv tswv yim.
3, Lithium titanate: muaj qhov zoo ntawm lub zog ceev, lub neej voj voog zoo thiab kev nyab xeeb, tab sis tus nqi kuj siab.
Hauv cov txheej txheem tsim cov roj teeb lithium-ion, ib qho tseem ceeb ntawm kev npaj ua ntej yog siv cov cuab yeej tshwj xeeb sib xyaw kom zoo sib xyaw cov khoom siv cathode thiab anode cais. Cov theem no tseem ceeb heev vim nws cuam tshuam ncaj qha rau qhov zoo thiab kev ua haujlwm ntawm cov txheej txheem tom ntej xws li txheej, winding, thiab sib dhos. Tshwj xeeb, cov ntaub ntawv cathode feem ntau muaj cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom sib txuas, uas yuav tsum tau muab sib xyaw kom zoo thiab sib xyaw ua ke hauv cov khoom sib xyaw kom zoo raws li qhov kub thiab txias, av noo, thiab kev sib hloov ceev. Qhov no ua kom ntseeg tau tias cov khoom siv tau sib npaug sib npaug los tsim cov txheej txheem zoo tshaj plaws slurry. Ib yam li ntawd, kev sib xyaw ntawm cov khoom siv anode ua raws cov qauv zoo sib xws, tab sis vim qhov sib txawv ntawm lawv cov tshuaj lom neeg muaj pes tsawg leeg thiab cov kev xav tau ntawm kev ua haujlwm, qhov sib xyaw tsis sib xws thiab cov khoom ntxiv yuav txawv. Los ntawm cov txheej txheem sib xyaw ua ke no, lub hauv paus ruaj khov tau muab tso rau cov txheej txheem txheej txheej tom ntej, ua kom cov khoom siv cathode thiab anode ua tib yam thiab tsis tu ncua coated rau cov khoom siv tam sim no, yog li ua kom muaj kev ruaj ntseg thiab sib xws ntawm lithium-ion roj teeb kev ua tau zoo.
3.Electrolyte
Cov electrolyte ua qhov nruab nrab rau lithium ion thauj hauv cov roj teeb lithium-ion, thiab nws cov khoom cuam tshuam ncaj qha rau lub roj teeb lub peev xwm, kev tiv thaiv sab hauv, thiab kev nyab xeeb. Feem ntau siv electrolytes yog tsim los ntawm cov kuab tshuaj organic thiab lithium ntsev, xws li lithium hexafluorophosphate. Tsis tas li ntawd, hom tshiab ntawm electrolytes, xws li solid-state electrolytes, yog tam sim no nyob rau hauv txoj kev loj hlob.
4. Sib cais
Lub separator yog ib qho tseem ceeb hauv cov roj teeb lithium-ion, nyob nruab nrab ntawm cov cathode thiab anode kom cais lawv thiab tiv thaiv kev luv luv. Nyob rau tib lub sijhawm, cov qauv microporous ntawm cov khoom sib cais tso cai rau lithium ions hla kev ywj pheej, ua kom lub roj teeb them thiab kev ua haujlwm tawm. Cov ntaub ntawv sib cais feem ntau yog ua los ntawm cov ntaub ntawv polymeric xws li polyolefins, uas yuav tsum tau muaj zog txhua yam, tshuaj stability, thiab roj permeability zoo.
5.Lwm yam khoom pab
Sib nrug los ntawm cov ntaub ntawv raw li hais saum toj no, kev tsim cov roj teeb lithium-ion tseem xav tau ntau cov ntaub ntawv pabcuam. Cov no suav nrog cov ntawv ci txhuas thiab tooj liab, uas yog cov khoom siv tam sim no, nrog rau cov ntaub ntawv zoo li CMC (carboxymethylcellulose sodium) thiab PVDF (polyvinylidene fluoride), uas ua haujlwm ua cov ntaub qhwv thiab cov ntaub ntawv txheej.
Thaum kawg, hauv cov txheej txheem tsim cov roj teeb lithium-ion, ib kauj ruam tseem ceeb yog muab cov roj teeb lithium-ion ua tiav thiab kev sib koom ua ke, ua haujlwm tau zoo PCBA (Printed Circuit Board Assembly) rau hauv cov txheej txheem npaj ua ntej uas ua tau raws li cov lus qhia tshwj xeeb. thiab qauv qauv. Cov kauj ruam no yuav tsum tsis yog tsuas yog ua tib zoo saib xyuas los ntawm cov neeg ua haujlwm kom paub meej qhov chaw thiab ruaj khov ntawm lub hlwb thiab kev tiv thaiv pawg thawj coj saib hauv cov hlau casing tab sis kuj tseem ua raws li cov lus qhia tshwj xeeb kom tsis txhob muaj qee yam uas yuav cuam tshuam rau kev ua haujlwm roj teeb lossis kev nyab xeeb. Nyob rau ntawm lub sijhawm no, los ntawm cov txheej txheem ntawm cov txheej txheem nyuaj thiab meej, cov txheej txheem tsim cov roj teeb lithium-ion tiav.
