Nyob rau hauv cov txheej txheem ntawm lithium roj teeb, lub tshuab txheej, raws li ib tug tseem ceeb piece ntawm cov cuab yeej, nws lub hauv paus kev ua tau zoo cuam tshuam ncaj qha rau txheej txheej thiab cov khoom zoo ntawm lithium roj teeb. Qhov kub hloov pauv yog qhov tseem ceeb cuam tshuam rau kev ruaj ntseg ntawm cov tshuab txheej. Qhov sib txawv ntawm qhov kub thiab txias ntawm granite hauv paus thiab cam khwb cia hlau hauv paus tau dhau los ua qhov tseem ceeb rau kev xaiv cov khoom siv hauv cov tuam txhab lithium roj teeb. cov
Coefficient ntawm thermal expansion: "kub tiv thaiv" kom zoo dua ntawm granite
Lub coefficient ntawm thermal expansion txiav txim qhov seem stability ntawm cov khoom thaum kub hloov. Lub coefficient ntawm thermal expansion ntawm cam khwb cia hlau puag yog kwv yees li 10-12 × 10⁻⁶ / ℃. Nyob rau hauv qhov kub hloov pauv ib puag ncig ntawm lithium roj teeb txheej kev cob qhia, txawm tias qhov ntsuas kub me me tuaj yeem ua rau qhov loj me me deformation. Piv txwv li, thaum qhov kub thiab txias nyob rau hauv lub rhiav fluctuates los ntawm 5 ℃, ib tug 1-meter ntev cam khwb cia hlau puag yuav undergo ib tug 50-60 μm expansion thiab contraction deformation. Qhov deformation no yuav ua rau muaj kev hloov pauv ntawm qhov sib txawv ntawm cov menyuam txheej txheej thiab cov ntawv electrode, uas ua rau cov txheej txheem tsis sib xws thiab tom qab ntawd cuam tshuam rau lub peev xwm thiab sib xws ntawm lithium roj teeb. cov
Nyob rau hauv sib piv, tus coefficient ntawm thermal expansion ntawm granite puag tsuas yog (4-8) × 10⁻⁶ / ℃, uas yog kwv yees li ib nrab ntawm cov cam khwb cia hlau. Nyob rau hauv tib qhov kub thiab txias ntawm 5 ℃, qhov deformation ntawm 1-meter-ntev granite puag tsuas yog 20-40 μm, thiab qhov kev hloov pauv yuav luag tsis quav ntsej. Thaum lub sijhawm ua haujlwm tas mus li ntev, lub hauv paus granite tuaj yeem ua kom ruaj khov, ua kom ntseeg tau qhov tseeb ntawm qhov chaw ntawm cov menyuam txheej thiab cov ntawv electrode, tswj kev ruaj ntseg ntawm txheej txheej txheej, thiab muab kev ruaj ntseg lav rau kev tsim cov roj teeb lithium zoo ib yam. cov
Thermal conductivity: Qhov "kub rwb thaiv tsev thaiv" yam ntxwv ntawm granite
Ntxiv nrog rau qhov kev hloov pauv loj los ntawm kev nthuav dav thermal, thermal conductivity ntawm cov ntaub ntawv tseem cuam tshuam rau qhov sib xws ntawm qhov kub thiab txias hauv cov khoom siv. Cam khwb cia hlau muaj zoo thermal conductivity. Thaum tshav kub tau tsim nyob rau hauv lub tshuab txheej vim lub cev muaj zog ua haujlwm, kev sib txhuam ntawm cov menyuam txheej, thiab lwm yam, lub hauv paus hlau cam khwb cia yuav ua kom sov sai, ua rau qhov kub thiab txias ntawm lub hauv paus nce thiab ua tsis sib xws. Qhov kub sib txawv no yuav ua rau thermal stress ntawm lub hauv paus, ntxiv intensifying deformation. Nyob rau tib lub sijhawm, nws kuj tseem tuaj yeem cuam tshuam rau kev ua haujlwm ib puag ncig ntawm qhov ntsuas qhov ntsuas qhov ntsuas thiab tswj cov khoom. cov
Granite yog cov khoom siv hluav taws xob tsis zoo, nrog cov thermal conductivity ntawm tsuas yog 2.7-3.3W / (m · K), uas yog qis dua li cov hlau cam khwb cia ntawm 40-60W / (m · K). Thaum lub sijhawm ua haujlwm ntawm lub tshuab txheej, lub hauv paus granite tuaj yeem thaiv qhov kev ua haujlwm ntawm cov cua sov sab hauv, txo qhov kub thiab txias ntawm lub hauv paus nto thiab tiam ntawm thermal stress. Txawm hais tias lub tshuab txheej ua haujlwm nyob rau hauv lub sijhawm ntev, lub hauv paus granite tseem tuaj yeem tswj tau qhov kub thiab txias ntawm lub xeev, zam cov khoom deformation thiab kev ua haujlwm degradation los ntawm qhov tsis sib xws, thiab tsim kom muaj qhov kub thiab txias ib puag ncig rau txheej txheej txheej. cov
Kev ruaj ntseg nyob rau hauv qhov kub thiab txias: Lub peev xwm ntawm "lub sij hawm ntev kub" ntawm granite
Kev tsim cov roj teeb lithium feem ntau xav tau cov cuab yeej ua haujlwm tsis tu ncua rau lub sijhawm ntev. Thaum lub sij hawm kub ntau zaus (xws li cua txias thaum hmo ntuj thiab cua sov thaum nruab hnub), kev ruaj ntseg ntawm cov khoom siv hauv paus yog qhov tseem ceeb heev. Raws li kev rov ua haujlwm ntawm thermal expansion thiab contraction, cam khwb cia hlau puag yog nquag ua rau qaug zog tawg hauv, uas ua rau txo qis hauv cov txheej txheem lub zog thiab cuam tshuam rau lub neej kev pab cuam ntawm cov khoom siv. Cov ntaub ntawv tshawb fawb ntsig txog pom tau tias tom qab 1000 qhov kub thiab txias (nrog qhov kub ntawm qhov sib txawv ntawm 20-40 ℃), qhov tawg qhov tob ntawm cov cam khwb cia hlau tuaj yeem ncav cuag 0.1-0.2 hli. cov
Granite bases muaj kev qaug zog zoo heev vim lawv qhov ntom ntom hauv cov ntxhia siv lead ua qauv. Nyob rau hauv tib qhov kev ntsuas kub ntawm kev sib tw, lub hauv paus granite tsis tshua pom pom cov kab nrib pleb, thiab cov qauv kev ntseeg tau khaws cia ntev. Qhov kev ruaj ntseg siab nyob rau hauv qhov kub thiab txias ua rau lub hauv paus granite kom tau raws li qhov kev siv siab thiab kev ua haujlwm ntev ntawm cov roj teeb lithium, txo cov txij nkawm thiab kev poob qis ntawm cov khoom siv los ntawm cov teeb meem hauv paus thiab txhim kho kev tsim khoom. cov
Tawm tsam keeb kwm yav dhau los ntawm kev xav tau nruj ntxiv rau qhov tseeb thiab kev ruaj ntseg hauv lithium roj teeb tsim, granite hauv paus, nrog lawv cov coefficient qis ntawm thermal expansion, superior thermal conductivity thiab zoo kub cycling stability, ho outperform cam khwb cia hlau bases nyob rau hauv cov nqe lus ntawm kub kuj. Xaiv lub lithium roj teeb txheej tshuab nrog lub hauv paus granite tuaj yeem txhim kho qhov tseeb ntawm cov khoom siv roj teeb, ua kom cov khoom siv roj teeb lithium zoo, txo cov khoom txaus ntshai thaum lub sijhawm tsim khoom, thiab dhau los ua ib qho tseem ceeb ntawm kev txhawb nqa kev loj hlob ntawm lithium roj teeb kev lag luam mus rau kev ua tau zoo dua.
