Koj puas tau hnov cov lus "tam sim no nyiam qhov chaw"? Qhov tshwm sim no, hu ua cov nyhuv tawv nqaij, yog lub tswvyim tseem ceeb hauv hluav taws xob engineering, tshwj xeeb hauv cov hluav taws xob siab. Txawm li cas los xij, dab tsi yuav tsis paub yog tias nws kuj yog qhov tsis cuam tshuam kev ua tau zoo ntawm cov roj teeb lithium. Hauv tsab xov xwm no, peb yuav tshawb txog cov tawv nqaij tawv, demynesify nws cov hauv paus ntsiab lus, thiab tshuaj xyuas nws qhov tseem ceeb hauv Lithium roj teeb tsim.
Dab tsi yog cov tawv nqaij ua tiav?
Cov lus piav yooj yim:
Thaum hluav taws xob hluav taws xob ntws los ntawm tus thawj coj, tshwj xeeb tshaj yog nyob rau hauv ntau zaus, nws zoo siab rau cov nplaim hluav taws xob tsis muaj tusyees hla ntawm ntu. Xav hauv cov tsheb neeg coob coob ntawm txoj kab kev loj ntawm txoj kev loj-qhov no zoo ib yam li tam sim no coj tus cwj pwm tam sim no.
Kev kawm txuj ci: lub hauv paus:
Cov nyhuv tawv tshwm sim los ntawm cov tshuab hluav taws xob sib txawv. High-zaus hloov cov kab khawb av tsim cov chaw sib nqus, uas ua rau muaj kev cuam tshuam tawm tsam eddy dej hauv tus neeg xyuas. Qhov no nce qhov cuam tshuam ntawm cov tub ntxhais, yuam tam sim no rau "khiav dim" mus rau saum npoo. Qhov ntau ntau zaus, tus ntiav ntiav ntawm qhov tob uas cov ntws tawm tam sim no (hu ua qhov tob ntawm qhov tawv nqaij).
Zoo li tsis cuam tshuam, tseem ceeb heev
Cov roj teeb lithium feem ntau ua haujlwm nyob rau hauv ncaj qha tam sim no (DC) lossis tsawg zaus mob, ua kom tawv nqaij tshwm sim tsis lees txais. Txawm li cas los xij, hauv qee qhov xwm txheej, nws ntsiag to cuam tshuam roj teeb:
Kev them nyiaj ceev ceev thiab tus nqi siab tawm: "tog" saum npoo "ntawm tam sim no
Qhov Teeb Meem:Thaum lub sij hawm them se nrawm, cov pulses tam sim no muaj cov khoom lag luam siab. Cov tawv nqaij tawv ua rau muaj qhov tseem ceeb ntawm cov nplaim hluav taws xob, txo cov khoom siv hauv cov khoom siv hauv sab hauv thiab cov peev xwm ua rau muaj kev loj hlob ntawm cov cheeb tsam thiab lithium dendrite loj hlob.
Kev Kawm Kev Kawm:Kev tshawb fawb qhia tau hais tias thaum muaj electradode qhov tob tshaj li qhov tob tob tshaj li qhov tob tob, them nyiaj nrawm nrawm tuaj yeem ncav cuag li 15%.
Electrode tsim: thinner zoo dua?
Kev pom zoo:Daim tawv nqaij qhov tob yog zaus-, thiab electrode thickness yuav tsum ua kom haum rau nws. Piv txwv li, yog tias qhov kev ua kom tawv nqaij loj yog 50 micrometers, ib qho tuab tuab tuab clet electrode (piv txwv li, tau tawm ntawm cov khoom tseem ceeb.
Kev Lag Luam Trend:Cov roj teeb hluav taws xob siab nce ntxiv siv thinner hluav taws xob (piv txwv li,<100 micrometers for power batteries) to enhance high-rate performance.
Nto Kho:Roughened los yog txheej txhuas / tooj liab ntim tuaj yeem nce thaj chaw ua tau zoo, kev tiv thaiv tawv nqaij los ntawm cov nyhuv tawv.
Cov kev daws teeb meem:3D Cov neeg khaws khoom siv tam sim no (piv txwv li, tooj liab ua npuas ncauj) muab ntau txoj hauv kev, dispersing ceev tam sim no ceev.
AC Kev Ntsuam Xyuas Kev Tshawb Xyuas (EIS): Ib "Stetoscope" rau kev noj qab haus huv roj teeb
EIS lub hauv paus ntsiab lus:Los ntawm kev txhaj tshuaj me me loj ac cim rau hauv lub roj teeb, impedance spectroscopy tshuaj xyuas cov xwm txheej sab hauv. Cov tawv nqaij ua rau muaj cov kab mob loj ntawm cov kab nkhaus siab, pab txheeb xyuas cov teeb meem saum npoo av thiab teeb meem sib cuam tshuam.
Cov kev sib tw thiab cov kev daws teeb meem los ntawm cov nyhuv tawv nqaij
Cov nyom:
Nto tam sim no concurration thaum thauj ceev → Hauv zos Lithium Lithium Dependition → dendrite kev pheej hmoo thiab luv luv kev pheej hmoo.
Kev siv qis ntawm tuab cov hluav taws xob → txwv hluav taws xob ceev.
Kev daws teeb meem:
Qeb theem:Siv nano-sized cov ntaub ntawv nquag (piv txwv li, nano-silicon anodes) kom muaj lithium-ion diffusion paths.
Txheej txheem kev tsim kho:Gradient electrode cov qauv tsim (muaj kev zoo siab nyob rau saum npoo, muaj peev xwm siab hauv cov tub ntxhais).
Cov tswv yim BMS:Dynamically Kho cov nqi them rau cov mem tes zaus kom tsis txhob muaj cov tawv nqaij kom ntau dhau.
Kev xam pom yav tom ntej: Cov nyuab tawv nqaij thiab cov roj teeb sib txuas ntxiv
Raws li cov roj teeb-lub luag haujlwm thiab cov ntawv thov siab (piv txwv li, cov tawv nqaij ua ntej, cov tawv nqaij ua ntej yuav dhau los ua kev tshaj tawm. Piv txwv li:
Cov roj teeb-lub xeev:Cov khoom siv hluav taws xob siab tuaj yeem ua rau cov tawv nqaij muaj txiaj ntsig zoo, iptionating optimized electrode / electrolyte interface tsim qauv.
HIGHLE NTAU YAM TSEEM CEEB:Cov roj teeb yuav tau daws cov roj teeb MHz-ntau zaus, txo qhov tob tob rau lub micrometer nplai thiab xav tau rov ua electrode qauv.
Xaus: Cov ntsiab lus txhais tau kev ua tau zoo
Cov nyuab tawv nqaij, feem ntau suav hais tias yog cov khoom siv hluav taws xob hauv hluav taws xob, ntsiag to cov khoom siv hluav taws xob kev siv hluav taws xob hauv "capillaries" ntawm cov roj teeb lithium. Los ntawm electradode cov txheej txheem them nyiaj ceev, txhua qhov sib zog thev naus laus zis yuav pob khaus ntawm kev tswj cov tawv nqaij tawv nqaij. Raws li cov roj teeb hloov zuj zus mus rau lub zog loj dua thiab zaus, "kev sib ntaus sib tua hauv deg" txuas ntxiv mus ua si pivotal.
Qhov no sau dua tshiab zam kev txhais lus ncaj qha thiab cov phev zoo li qub, ua kom pom tseeb thaum muaj kev paub tseeb thiab nyeem tau rau koj Google lub vev xaib. Nws tau ua kom haum rau koom nrog cov neeg saib xyuas thoob ntiaj teb thiab txhim kho SEO kev ua haujlwm.
