Qhov qhov sib txawv ntawm lithium carbonate thiab lithium hydroxideyog lithium carbonate muaj ib qho carbonate anion txuam nrog ob lithium cations whereas lithium hydroxide muaj ib lithium cation txuam nrog ib hydroxide anion.
Ob leeg lithium carbonate thiab lithium hydroxide yog qhov tseem ceeb hauv kev tsim cov khoom siv cathode rau lithium-ion roj teeb. Txawm li cas los xij, muaj ob peb qhov sib txawv ntawm ob yam khoom no.
Lithium Carbonate yog dab tsi?
Lithium carbonate yog ib qho inorganic compound uas muaj cov tshuaj formula Li2CO3. Nws yog lithium ntsev ntawm carbonic acid. Nws zoo nkaus li cov hmoov dawb uas tsis muaj ntxhiab tsw. Nws muaj ntau daim ntawv thov hauv kev ua cov hlau oxides thiab tseem muaj txiaj ntsig zoo li cov tshuaj hauv kev kho mob siab. Piv txwv li, nws yog ib qho ntawm cov tshuaj tseem ceeb tshaj plaws siv los kho kev puas siab puas ntsws bipolar.
Daim duab 01: Lub Crystal Structure ntawm Lithium Carbonate
Hauv kev lag luam kev siv, lithium carbonate tseem ceeb heev ua tus thawj coj rau cov tebchaw uas peb siv los ua cov roj teeb lithium-ion. Tsis tas li ntawd, tsom iav uas yog tsim los ntawm lithium carbonate yog qhov tseem ceeb heev hauv kev tsim cov khoom siv hluav taws xob. Peb tuaj yeem pom cov khoom sib xyaw no ua cov khoom muaj nyob rau hauv ob qho tib si hluav taws kub thiab hluav taws kub kub ceramic glaze. Nws tuaj yeem tsim cov fluxes qis nrog silica thiab lwm yam ntaub ntawv. Tsis tas li ntawd, cov khoom alkaline ntawm lithium carbonate ua rau kev hloov pauv ntawm lub xeev ntawm cov hlau oxide xim nyob rau hauv glaze. E.g. liab hlau oxide. Tsis tas li ntawd, cov cement feem ntau teeb tsa sai dua thaum nws npaj nrog lithium carbonate.
Lithium Hydroxide yog dab tsi?
Lithium hydroxide yog ib qho inorganic compound uas muaj cov tshuaj formula LiOH. Muaj ob daim ntawv; lawv yog daim ntawv hydrated thiab daim ntawv anhydrous. Tus naj npawb ntawm cov dej molecules hauv daim ntawv hydrated tuaj yeem sib txawv. Ob daim ntawv hydrated thiab anhydrous yog hygroscopic solids uas yog soluble hauv dej thiab me ntsis soluble hauv ethanol. Ntxiv mus, ob daim ntawv no yog kev lag luam muaj nyob rau hauv ntau daim ntawv thov. Peb tuaj yeem faib nws raws li lub hauv paus muaj zog. Txawm li cas los xij, nws yog qhov tsis muaj zog alkali hlau hydroxide paub txog tam sim no.
Daim duab 02: Lub Crystal Structure ntawm Lithium Hydroxide
Cov pob zeb nyuaj spodumene yog cov khoom noj siv rau kev tsim cov lithium hydroxide. Cov tshuaj no muaj nws cov ntsiab lus lithium qhia raws li feem pua ntawm lithium oxide. Feem ntau, kev tsim cov lithium hydroxide yog ua los ntawm kev siv cov tshuaj tiv thaiv metathesis siv calcium hydroxide. Raws li lwm txoj hauv kev, peb tuaj yeem siv lithium sulfate.
Muaj ntau yam tseem ceeb ntawm kev siv lithium hydroxide, suav nrog kev tsim cov roj teeb lithium-ion, ua cov roj thickener, hauv cov pa roj purification systems rau lub dav hlau, ua cov intermediates rau kev tsim cov lithium-muaj cov tebchaw, hauv kev tsim cov ceramics rau alkalization, thiab lwm yam.
Qhov txawv ntawm Lithium Carbonate thiab Lithium Hydroxide yog dab tsi?
Ob leeg lithium carbonate thiab lithium hydroxide yog qhov tseem ceeb hauv kev tsim cov khoom siv cathode rau lithium-ion roj teeb. Txawm li cas los xij, muaj qee qhov sib txawv ntawm lithium carbonate thiab lithium hydroxide. Ntawm lawv, qhov sib txawv tseem ceeb ntawm lithium carbonate thiab lithium hydroxide yog lithium carbonate muaj ib qho carbonate anion txuam nrog ob lithium cations thaum lithium hydroxide muaj ib lithium cation txuam nrog ib qho hydroxide anion. Tsis tas li ntawd, lithium carbonate tsis kim dua lithium hydroxide.
Summary – Lithium Carbonate vs Lithium Hydroxide
Lithium carbonate thiab lithium hydroxide yog ib qho tseem ceeb ntawm cov tshuaj inorganic. Qhov sib txawv tseem ceeb ntawm lithium carbonate thiab lithium hydroxide yog lithium carbonate muaj ib qho carbonate anion txuam nrog ob lithium cations thaum lithium hydroxide muaj ib lithium cation txuam nrog ib qho hydroxide anion. Tsis tas li ntawd, lithium carbonate tsis kim dua lithium hydroxide.
