Zida Zanzeru zamabatire a Lithium

Pankhani ya kusalowerera ndale kwa kaboni komanso zomwe zikuchitika padziko lonse lapansi pakuyika magetsi pamagalimoto, lithiamu, monga chinthu chofunikira kwambiri pamunda wa batri, ikuyembekezeka kupitiliza kupindula ndi kusintha kwamphamvu kwamphamvu mu mphamvu zake ndi malo osungiramo mphamvu.Lithium ili ndi unyolo wathunthu wamafakitale, kupanga zinthu kuchokera ku ore kumtunda ndi nyanja zamchere mpaka pakatilithiamu carbonate, lithiamu hydroxide ndi zitsulo lifiyamu, ndi kunsi kwa mtsinje mafakitale chikhalidwe (zitsulo smelting, lubricant, ceramic galasi, etc.), zipangizo zatsopano (organic synthesis, biomedicine) ndi mphamvu zatsopano (3C mabatire, mabatire mphamvu, etc.) ndi zina ntchito-mbali unyolo wathunthu wamakampani.Lithium hydroxidendi imodzi mwazinthu zitatu zamchere za lithiamu mumndandanda wamakampani a lithiamu.Kufunika kwapansi pamtsinje makamaka kumachokera ku batire yamagetsi, malo opangira batire, ndi malo ogulitsa omwe amaimiridwa ndi kupanga mafuta a lithiamu ndi magalasi a ceramic.Mitundu yake yayikulu makamaka imaphatikizapo anhydrous Lithium hydroxide (LiOH) ndi lithiamu hydroxide monohydrate (LiOH · H2O).

Lithium hydroxide ndi chinthu chofunikira kwambiri pakugwiritsa ntchito mabatire amphamvu, makamaka chapamwamba cha nickel ternary cathode chomwe chimagwiritsidwa ntchito kwambiri pamabatire amphamvu kwambiri, ndipo ndichofunikira kwambiri pakupanga kwake.Zida zapamwamba za nickel ternary zimagawidwa kukhala NCM811 ndi NCA.Makampani aku China makamaka amapanga NCM811, ndipo makampani aku Japan ndi Korea makamaka amatulutsa NCA.Pakalipano, magalimoto atsopano osiyanasiyana omwe ali ndi mabatire apamwamba a nickel ternary ali ndi maulendo oposa 500km.Gawo la batire la ogula limaphatikizapo mafoni, mapiritsi, zida za TWS, ndi ma drones.

High faifi tambala ternary zipangizo amafuna 700 ~ 800 ° C sintering kutentha, koma lifiyamu carbonate zambiri sintered pafupifupi 900 ° C kuti achite zinthu zabwino zakuthupi, pamene kusungunuka kwa lithiamu hydroxide ndi 471 ° C, ndi reactivity amphamvu ndi corrosiveness wamphamvu.Maonekedwe ake akuthupi ndi mankhwala amapangitsa lithiamu hydroxide kukhala yofunika kwambiri pakupangira matenthedwe apamwamba a faifi tambala ternary cathode, kotero ndi chisankho chosapeŵeka cha zida zapamwamba za nickel ternary.

Mafakitale atatu apamwamba kwambiri padziko lonse lapansi potengera kuchuluka kwa mabatire amagetsi onse awonetsa kuti ternary yapamwamba kwambiri ndiye njira yayikulu yopititsira patsogolo (Ningde era - NCM622/811, Japan's Panasonic - NCA, LG Chem yaku South Korea - NCM622 /811), gawo la msika la CR3 lidafika pafupifupi magawo awiri pa atatu pomwe likukula kwambiri.M'tsogolomu, ndi kuchuluka kwa kuchuluka kwa nickel ternary m'magalimoto atsopano amphamvu, lithiamu hydroxide monga maziko ake adzabweretsanso kukula komwe sikunachitikepo.
