Dabarun Kayayyakin Batir Lithium

A cikin mahallin tsaka-tsakin carbon da yanayin duniya na samar da wutar lantarki, lithium, a matsayin babban abu a cikin filin baturi, ana sa ran zai ci gaba da cin gajiyar canjin makamashi mai tsabta a cikin wutar lantarki da wuraren ajiyar makamashi.Lithium yana da cikakken sarkar masana'antu, samar da kayayyaki daga sama da tafkunan gishiri zuwa tsakiyar rafilithium carbonate, lithium hydroxide da karfe lithium, da masana'antun gargajiya na ƙasa (ƙarfe smelting, lubricants, yumbu gilashin, da dai sauransu), sabon kayan (kwayoyin halitta, biomedicine) da sabon makamashi (3C baturi, ikon baturi, da dai sauransu) da sauran aikace-aikace-gefe. cikakken masana'antu sarƙoƙi.Lithium hydroxideyana daya daga cikin manyan gishirin lithium guda uku a cikin sarkar masana'antar lithium.Bukatar ƙasa ta samo asali ne daga filin baturi, filin baturi na mabukaci, da kuma filin masana'antu wanda ke wakilta ta samar da mai mai tushen lithium da yumbun gilashi.Babban siffofinsa sun haɗa da lithium hydroxide (LiOH) mai anhydrous da lithium hydroxide monohydrate (LiOH·H2O).

Lithium hydroxide wani muhimmin danyen abu ne a fagen samar da batura, musamman ma babban nickel ternary cathode abu wanda ake amfani da shi sosai a cikin batura masu ƙarfi, kuma shine tushen tushen lithium mai mahimmanci a cikin samarwa.Manyan kayan ternary nickel an raba su zuwa NCM811 da NCA.Kamfanonin kasar Sin sun fi samar da NCM811, kuma kamfanonin Japan da Koriya sun fi samar da NCA.A halin yanzu, sabbin motocin makamashi iri-iri masu dauke da manyan batura masu karfin nickel suna da kewayon sama da kilomita 500.Bangaren baturin mabukaci ya haɗa da wayoyi, allunan, na'urorin TWS, da drones.

Babban nickel ternary kayan yana buƙatar 700 ~ 800 ° C sintering zafin jiki, amma lithium carbonate ne sau da yawa sintered a game da 900 ° C don aiwatar da manufa kayan kaddarorin, yayin da narkewa batu na lithium hydroxide ne 471 ° C, tare da karfi reactivity da kuma karfi lalata.Abubuwan da ke cikin jiki da sinadarai suna sa lithium hydroxide ya zama makawa don haɓakar haɓakar haɓakar kayan haɓakar nickel na ternary cathode, don haka zaɓi ne da babu makawa don manyan abubuwan nickel ternary.

Manyan masana'antun batir guda uku a duniya dangane da shigar karfin batura duk sun bayyana karara cewa babban nickel ternary shine babban hanyar ci gaba (zamanin Ningde - NCM622/811, Panasonic na Japan - NCA, LG Chem na Koriya ta Kudu - NCM622) /811), rabon kasuwar CR3 ya kai kusan kashi biyu bisa uku yayin da ake ci gaba da samun babban ci gaba.A nan gaba, tare da haɓaka ƙarfin ƙarfin babban nickel ternary a cikin sabbin motocin makamashi, lithium hydroxide a matsayin ainihin kayan zai kuma shigar da sararin ci gaban da ba a taɓa gani ba.
