Plaub Cheebtsam ntawm Li-ion roj teeb
Ntau cov khoom siv hauv tsev juggernauts tam sim no scrambling tso cordless stick nqus tsev vacuum.
Ntau tus neeg nyiam cov khoom siv no vim nws lub teeb txaus rau cov menyuam yaus siv thaum tseem muaj lub zog nqus zoo heev.
Li-ion roj teeb ua rau nws ua tau rau lub tshuab nqus tsev cordless tsim, feem ntau.
Lub zog ceev ceev tseem ua lub teeb Li-ion roj teeb muaj txiaj ntsig zoo dua thiab muaj peev xwm ntau dua li cov roj teeb li qub.
feem ntau siv rau hauv ntau qhov chaw, suav nrog cov cuab yeej hluav taws xob, lub zog cia, cov khoom siv me me, thiab cov khoom siv IT.
nrog rau cov tsheb hluav taws xob.
Niaj hnub no, cia peb tshuaj xyuas Li-ion roj teeb los ntawm sab saum toj mus rau hauv qab.
Cathode, Anode, Electrolyte, thiab Li-ion roj teeb muaj plaub yam.
Separator
Cathode, anode, electrolyte, thiab separator yog plaub yam tseem ceeb ntawm lithium-ion roj teeb.
Lub roj teeb Li-ion xav tau txhua yam thiab txhua yam vim nws tsis tuaj yeem ua haujlwm yog tias ib qho ntawm lawv tsis tuaj.
Lub roj teeb Li-ion "cathode" cuam tshuam nws lub peev xwm thiab qhov hluav taws xob.
Lub lithium nyob rau hauv lub lithium-ion roj teeb tau dhau los ua cov txheej txheem tshuaj los tsim lub zog.
Vim li no, lithium yog ib txwm nkag mus rau hauv lub roj teeb, thiab thaj chaw uas lithium nyob yog hu ua "cathode."
Lithium oxide yog siv rau cathodes vim lithium hauv nws daim ntawv tseem ceeb, uas muaj lithium thiab oxygen, tsis ruaj khov.
Lo lus "cov khoom siv" yog hais txog ib yam khoom xws li lithium oxide uas thaiv cov tshuaj tiv thaiv electrode ntawm lub roj teeb tiag.
Hauv lwm lo lus, lithium oxide ua lub luag haujlwm tseem ceeb hauv cathode ntawm Li-ion roj teeb.
Ib daim ntawv nyias nyias siv los txhawb cov cathode lub coated thav duab yuav pom tau yog tias koj saib cov cathode ze.
siv ib tug sib tov ntawm ib tug active tshuaj, ib tug conductive additive, thiab ib tug binder.
Lithium ions yog tam sim no nyob rau hauv lub active tshuaj, thiab ib tug conductive additive yog ntxiv los txhim kho conductivity;
Tsis tas li ntawd, lub binder ua hauj lwm raws li ib tug nplaum los pab nyob rau hauv kom zoo adhesion ntawm conductive additive thiab active khoom rau cov txhuas substrate.
Lub roj teeb lub zog muaj zog cuam tshuam los ntawm cathode.
vim tias cov cathode cov khoom siv nquag cuam tshuam rau lub roj teeb lub zog thiab lub peev xwm.
Lub peev xwm nce nrog qhov ntau ntawm lithium tam sim no, thiab qhov hluav taws xob nce nrog qhov loj ntawm qhov sib txawv ntawm cov cathode thiab anode.
Nyob ntawm hom, qhov sib txawv ntawm anodes thiab cathodes feem ntau yog me me rau anodes thiab me ntsis tseem ceeb rau cathodes.
Yog li ntawd, lub cathode yog qhov tseem ceeb hauv kev txiav txim siab lub roj teeb lub zog.
"Anode" xa cov electrons los ntawm ib tug hlau.
Lub anode substrate yog them nrog active khoom, ib yam li cov cathode.
Lub luag haujlwm ntawm cov khoom siv anode yog tso cai rau cov hluav taws xob tam sim no dhau los ntawm cov hluav taws xob sab nraud.
Lithium ions tso tawm los ntawm cathode tuaj yeem nqus tau lossis tso tawm rov qab thaum ua li ntawd.
Lithium ions tau khaws cia hauv lub anode, tsis yog cathode, thaum lub roj teeb raug them.
Thaum lub cathode thiab anode txuas nrog tam sim no los ntawm kev xaim hluav taws xob (hauv qhov xwm txheej tawm),
Cov electrolyte ib txwm tso cai rau lithium ions rov qab mus rau cathode,
thiab cov lithium ions 'sib cais electrons (e-) ntws los ntawm cov hlau thaum tsim hluav taws xob.
Kev siv cov graphite ruaj khov rau anodes thiab txheej txheej ntawm cov khoom siv ntawm cov khoom siv anode substrate
ib tug binder thiab ib tug conductive additive.
Graphite cov yam ntxwv zoo tshaj plaws, uas yog nws cov qauv kev ruaj ntseg thiab tsis tshua muaj hluav taws xob electrochemical reactivity,
Cov khoom siv tau xav tias tsim nyog rau kev siv raws li anode muab nws tus nqi pheej yig thiab muaj peev xwm khaws cia ntau lithium ions.
"Electrolyte" tsuas yog tso cai ion txav mus los.
Nws tau hais tias lithium ions ntws los ntawm electrolyte thaum tham txog cathode thiab anode.
thiab cov hlau yog ntim nrog electrons.
Qhov no yog qhov tseem ceeb rau kev cia lub roj teeb siv hluav taws xob.
Peb yuav tsis muaj peev xwm siv hluav taws xob thiab peb txoj kev nyab xeeb yuav muaj kev phom sij yog tias ions dhau los ntawm electrolyte.
Lub ntsiab lus uas ua kom tiav qhov tseem ceeb no yog cov electrolyte.
Nws ua raws li cov kav dej uas tso cai rau cov lithium ions tsuas yog taug kev rov qab los ntawm cov cathode thiab cov anode.
Cov khoom siv hluav taws xob ionic siab feem ntau yog siv rau cov electrolyte kom lithium ions tuaj yeem rov qab mus tau yooj yim.
Muaj cov ntsev, cov kuab tshuaj, thiab cov khoom ntxiv hauv cov electrolyte.
Lithium ions ntws los ntawm cov ntsev, uas yog yaj hauv cov kua organic hu ua cov kuab tshuaj.
thiab rau qee lub hom phiaj, cov additives yog qhia nyob rau hauv tsawg qhov ntau.
Txoj kev ua electrolyte no tiv thaiv cov hluav taws xob los ntawm kev hla thiab tsuas yog tso cai ions ntws mus rau cov electrodes.
Tsis tas li ntawd, hom electrolyte cuam tshuam sai npaum li cas lithium ions migrate.
Yog li ntawd, tsuas yog cov electrolytes uas ua raws li cov cai nruj yuav siv tau.
"Separator," lub impermeable muab faib cais cathode thiab anode
Lub electrolyte thiab separator txhais lub roj teeb kev nyab xeeb, thaum lub cathode thiab anode txiav txim siab lub roj teeb qhov kev ua tau zoo.
Separator ua kom cathode thiab anode sib nrug los ntawm kev ua raws li lub cev tiv thaiv.
Nws ua tib zoo tso cai rau tsuas yog cov ions dhau los ntawm lub qhov me me sab hauv thaum cuam tshuam qhov ncaj qha ntawm electrons.
Nws yuav tsum ua tau raws li tag nrho cov kev cai ntawm lub cev thiab electrochemical.
Niaj hnub no cov khoom siv hluav taws xob sib cais, xws li polyethylene (PE) thiab polypropylene (PP), yog muag.
Peb tau tshuaj xyuas plaub yam tseem ceeb uas cuam tshuam rau Li-ion roj teeb ua haujlwm zoo li cas txog tam sim no.
Tam sim no, Samsung SDI tab tom txhim kho kev tshawb fawb thiab tsim cov ntaub ntawv tshiab rau kev txhim kho roj teeb.
thaum tsis tu ncua nqa nws txoj kev siv zog los txhim kho kev ua haujlwm ntawm cov ntaub ntawv tam sim no thiab cov thev naus laus zis tseem ceeb.
Los ntawm txoj kev loj hlob ntawm lub peev xwm, high-efficiency Li-ion roj teeb,
Samsung SDI xav ua tus coj txoj hauv kev txhim kho cov roj teeb uas yuav txhim kho lub neej zoo rau tib neeg thoob plaws ntiaj teb.
