Ib qho ntawm cov hlau tseem ceeb tshaj plaws hauv ntiaj teb yog tooj liab. Yog tsis muaj nws, peb tsis muaj peev xwm ua tej yam uas peb tau txais kev tso cai xws li tig teeb lossis saib TV. Tooj liab yog cov hlab ntsha uas ua rau lub computer ua haujlwm. Peb yuav tsis tuaj yeem taug kev hauv tsheb yam tsis muaj tooj liab. Kev sib txuas lus yuav nres tuag. Thiab cov roj teeb lithium-ion yuav tsis ua haujlwm txhua yam tsis muaj nws.
Cov roj teeb lithium-ion siv cov hlau xws li tooj liab thiab txhuas los tsim hluav taws xob. Txhua lub roj teeb lithium-ion muaj graphite anode, hlau oxide cathode, thiab siv cov electrolytes uas muaj kev tiv thaiv los ntawm cov khoom sib cais. Them lub roj teeb ua rau lithium ions ntws los ntawm cov electrolytes thiab sau ntawm graphite anode nrog rau cov electrons xa los ntawm kev sib txuas. Unplugging lub roj teeb xa cov ions rov qab qhov chaw lawv tuaj thiab yuam cov electrons mus rau hauv Circuit Court tsim hluav taws xob. Lub roj teeb yuav ploj mus thaum tag nrho cov lithium ions thiab electrons rov qab mus rau cathode.
Yog li, dab tsi tooj liab ua si nrog lithium-ion roj teeb? Graphite yog fused nrog tooj liab thaum tsim cov anode. Copper tiv taus oxidization, uas yog cov txheej txheem tshuaj uas electrons ntawm ib lub caij ploj mus rau lwm lub caij. Qhov no ua rau corrosion. Oxidization tshwm sim thaum cov tshuaj thiab cov pa oxygen cuam tshuam nrog lub ntsiab lus, zoo li yuav ua li cas hlau los ntawm kev sib cuag nrog dej thiab oxygen tsim xeb. Tooj liab yog qhov tseem ceeb tiv thaiv corrosion.
tooj liab ntawv cifeem ntau yog siv hauv cov roj teeb lithium-ion vim tias tsis muaj kev txwv nrog nws qhov loj me. Koj tuaj yeem muaj nws ntev npaum li koj xav tau thiab nyias raws li koj xav tau. Copper yog los ntawm nws qhov xwm txheej uas muaj zog tam sim no, tab sis nws kuj tso cai rau qhov zoo thiab sib npaug ntawm qhov tam sim no.
Muaj ob hom ntawv tooj liab: dov thiab electrolytic. Koj qhov yooj yim dov tooj liab ntawv ci yog siv rau txhua yam khoom siv tes ua thiab tsim. Nws yog tsim los ntawm cov txheej txheem ntawm kev qhia cov cua sov thaum nias nws nrog dov pins. Tsim electrolytic tooj liab ntawv ci yog siv tau rau hauv kev siv tshuab yog ib qho kev koom tes me ntsis. Nws pib los ntawm dissolving zoo tooj liab nyob rau hauv acid. Qhov no tsim cov tooj liab electrolyte uas tuaj yeem muab ntxiv rau tooj liab los ntawm cov txheej txheem hu ua electrolytic plating. Hauv cov txheej txheem no, hluav taws xob yog siv los ntxiv cov tooj liab electrolyte rau cov ntawv ci tooj liab hauv cov khoom siv hluav taws xob rotating nruas.
Copper foil tsis yog tsis muaj nws qhov tsis zoo. Copper ntawv ci tuaj yeem hloov pauv. Yog hais tias qhov no tshwm sim, lub zog sau thiab dispersion tuaj yeem cuam tshuam loj heev. Dab tsi ntxiv yog tias cov ntawv ci tooj liab tuaj yeem cuam tshuam los ntawm cov chaw sab nraud xws li cov teeb liab electromagnetic, lub zog microwave, thiab cov cua sov heev. Cov yam tseem ceeb no tuaj yeem ua rau qeeb lossis txawm tias ua rau cov ntawv ci tooj liab ua haujlwm tau zoo. Alkalis thiab lwm cov kua qaub tuaj yeem ua rau cov ntawv ci tooj liab ua haujlwm tau zoo. Qhov no yog vim li cas cov tuam txhab xws liCIVENCov hlau tsim ntau yam khoom siv tooj liab.
Lawv tau thaiv cov ntawv ci tooj liab uas tiv thaiv tshav kub thiab lwm yam kev cuam tshuam. Lawv ua cov ntawv ci tooj liab rau cov khoom tshwj xeeb xws li cov ntawv luam tawm Circuit Court boards (PCBs) thiab flexible circuit boards (FCBs). Lawm, lawv ua tooj liab ntawv nyiaj rau lithium-ion roj teeb.
Cov roj teeb lithium-ion tau dhau los ua ntau tus qauv, tshwj xeeb tshaj yog nrog cov tsheb vim lawv lub zog induction motors zoo li cov Tesla tsim. Induction motors muaj qhov txav tsawg dua thiab muaj kev ua haujlwm zoo dua. Induction motors tau suav hais tias yog qhov tsis tuaj yeem muab lub zog xav tau uas tsis muaj nyob rau lub sijhawm. Tesla tuaj yeem ua qhov no tshwm sim nrog lawv cov roj teeb lithium-ion. Txhua lub xov tooj ntawm tes yog tsim los ntawm ib tus kheej lithium-ion roj teeb, tag nrho cov ntawv muaj tooj liab.
Qhov kev thov rau cov ntawv ci tooj liab tau mus txog qhov siab heev. Kev ua lag luam tooj liab ua tau ntau dua 7 billion las Asmeskas hauv 2019 thiab nws xav tias yuav ua tau ntau dua 8 billion las Asmeskas hauv 2026. Qhov no yog vim muaj kev hloov pauv hauv kev lag luam tsheb uas tau cog lus tias yuav hloov los ntawm cov tshuab hluav taws xob sab hauv mus rau lithium-ion roj teeb. Txawm li cas los xij, tsheb yuav tsis yog qhov kev lag luam nkaus xwb uas cuam tshuam nrog cov khoos phis tawj thiab lwm yam khoom siv hluav taws xob kuj siv tooj liab. Qhov no tsuas yog xyuas kom meej tias tus nqi rautooj liab ntawv ciyuav nce ntxiv nyob rau hauv kaum xyoo tom ntej.
Cov roj teeb lithium-ion tau tsim thawj zaug hauv xyoo 1976, thiab lawv yuav ua lag luam loj hauv xyoo 1991. Nyob rau xyoo tom qab, cov roj teeb lithium-ion yuav nrov dua thiab yuav raug kho kom zoo dua. Muab lawv siv hauv tsheb, nws muaj kev nyab xeeb hais tias lawv yuav pom lwm yam kev siv hauv lub ntiaj teb uas muaj hluav taws xob hluav taws xob nyob hauv lub ntiaj teb vim tias lawv tuaj yeem siv tau thiab siv tau zoo dua. Lithium-ion roj teeb yog lub neej yav tom ntej ntawm lub zog, tab sis lawv tsis muaj dab tsi tsis muaj ntawv ci tooj liab.
