I-Trimanganese tetroxide isetshenziswa kakhulu ekukhiqizeni izinto ezithambile zikazibuthe nezinto ze-cathode zamabhethri e-lithium. Izindlela eziyinhloko zokulungiselelaI-Trimanganese Tetroxidehlanganisa indlela yensimbi ye-manganese, indlela ye-high-valent manganese oxidation, indlela ye-manganese kasawoti kanye nendlela ye-manganese carbonate. Indlela ye-metal manganese oxidation iwumzila wenqubo ojwayelekile kakhulu njengamanje. Le ndlela isebenzisa insimbi ye-electrolytic manganese njengempahla eluhlaza, futhi yenza ukumiswa kwe-manganese ngokugaya, futhi i-oxidize ngokudlula umoya ngaphansi kwezimo zokushisa okuthile kanye ne-catalyst, futhi ekugcineni ithole imikhiqizo ye-tetraoxide ye-manganese ngokuhlunga, ukuwasha, ukomisa nezinye izinqubo. I-Manganese sulfate ilungiswa ngezinyathelo ezimbili zendlela ye-oxidation. Okokuqala, i-sodium hydroxide yengezwe kusisombululo se-high-purity manganese sulfate ukuze kuncishiswe imvula, futhi ngemva kokuba imvula igezwe izikhathi eziningana, kwethulwa umoya-mpilo ukuze kufezeke ukusabela kwe-oxidation. Ngemuva kwalokho, i-precipitate ihlale igezwa, ihlungiwe, iguge, iphonswe futhi yomiswe ukuze kutholwe i-high-purity trimanganese tetraoxide.
Eminyakeni yamuva nje, ngenxa yesidingo esiphelele sezinto ezibonakalayo ezithambile zikazibuthe kanye nezinto ezinhle ze-electrode ezifana ne-lithium manganate, ukukhiqizwa kwe-manganese tetraoxide yaseChina kuye kwaqhubeka nokukhula. Imininingwane ikhombisa ukuthi ukukhiqizwa kwe-manganese tetraoxide yaseChina kuzofinyelela kumathani ayi-10.5 ngo-2021, okuwukunyuka okungaba ngu-12.4% ngonyaka ka-2020. Ngo-2022, njengoba izinga lokukhula lilonke lesidingo se-lithium manganate nezinye lehlile, umkhiqizo usuwonke kulindeleke ukuthi ukhuphuke. kancane. NgoZibandlela wezi-2022, umkhiqizo waseChina usuwonke we-manganese tetraoxide wafinyelela amathani ayi-14,000, ukwehla kancane kusukela enyangeni edlule. Phakathi kwazo, ukukhishwa kwebanga le-elekthronikhi kanye nebanga lebhethri bekungamathani ayi-8,300 kanye namathani angama-5,700 ngokulandelana, kanti lonke ibanga le-elekthronikhi libalwa ngenani eliphakeme kakhulu, elifinyelela cishe ku-60%. Kusukela ngo-2020 kuya ku-2021, njengoba isidingo sisonke sasekhaya sase-China silokhu sikhuphuka, kanye nokuhlinzekwa kwe-electrolytic manganese ekhuphukayo kwehla, izinto zokusetshenziswa zizokwenyuka kakhulu, okuzoholela emananini ayo yonkemanganese tetraoxideeqhubeka nokuvuka. Uma sibheka unyaka wonke ka-2022, isidingo sisonke sasekhaya saseShayina se-manganese tetraoxide siyavilapha futhi siphakeme kakhulu, izindleko zokucindezela kwezinto ezingavuthiwe zehlile, futhi intengo iqhubekile nokwehla. Ekupheleni kukaZibandlela, bekucishe kube ngu-16 yuan/kg, obekuwukwehla okuphawulekayo kusuka cishe ku-40 yuan/kg ekuqaleni konyaka.
Ngokombono wohlangothi lokuhlinzeka, amandla okukhiqiza aseShayina kanye nokuphuma kwe-manganese tetraoxide kuqala emhlabeni, kanye nekhwalithi yomkhiqizo wayo isezingeni elisezingeni eliphezulu lamazwe ngamazwe. Amabhizinisi amahlanu aphezulu emandleni okukhiqiza aseShayina enza ngaphezu kwama-90% omthamo womhlaba wonke wokukhiqiza, ikakhulukazi e-Hunan, Guizhou, Anhui nakwezinye izindawo. Ukukhiqizwa kwe-manganese tetraoxide ngamabhizinisi ahamba phambili kuqala emhlabeni, okubalela cishe amaphesenti angama-50 emakethe yasekhaya eChina. Le nkampani ikhiqiza amathani angu-5,000 e-battery-grade manganese tetraoxide, esetshenziswa kakhulu ekwenzeni i-soft magnetic manganese-zinc ferrite, nasekukhiqizeni ama-electrode amahle e-lithium manganese oxide namabhethri e-lithium manganese iron phosphate lithium-sodium ion. Le nkampani isanda kwengeza amathani ayi-10,000 omthamo wokukhiqiza we-manganese tetraoxide webhethri, okulindeleke ukuthi ikhishwe ku-Q2 ngo-2023.
