Amabhethri e-lithium angubuchwepheshe bebhethri obuthuthuke kakhulu namuhla, anomthamo omkhulu wamandla, impilo ende, ukuzikhipha okuphansi, ukuvikelwa kwemvelo kanye nezinye izinzuzo.Asetshenziswa kakhulu kuma-smart phone, ama-laptops nakweminye imikhiqizo kagesi, kanye nasezimotweni ezintsha zamandla namandla omoya, amandla elanga kanye nezinye izisetshenziswa ezinkulu zokugcina amandla.Ngezinhloso zokuncishiswa kwekhabhoni yomhlaba wonke, ukuguqulwa kokufakwa kukagesi kanye nemithethonqubo yenqubomgomo, isidingo semakethe yebhethri ye-lithium sibonisa ukukhula okukhulu.Kulindeleke ukuthi ngo-2025, usayizi wemakethe yebhethri ye-lithium emhlabeni wonke ufinyelele ku-1.1 trillion US dollar.
Ukusebenza kanye nekhwalithi yamabhethri e-lithium akuxhomekile kuphela emsebenzini nasekuzinzeni kwe-lithium ion, kodwa futhi ekukhethweni nasekulinganiseni kwezinto zebhethri.Phakathi kwazo, i-magnesium carbonate iyinto ebalulekile yebhethri, esetshenziselwa ikakhulukazi ukwenza isandulela sezinto ezinhle ze-electrode, futhi ingasetshenziswa ukuthuthukisa ukwakheka nokuqhutshwa kwezinto ezingezinhle ze-electrode.I-Magnesium carbonate idlala indima ebalulekile kumabhethri e-lithium, kodwa ungayikhetha kanjani ikhwalithi ephezulu ye-magnesium carbonate?Nawa amanye amathiphu:
- Hlola ukuthi okuqukethwe okuyinhloko kwe-magnesium carbonate kuzinzile yini.Okuqukethwe okuyinhloko kwe-magnesium carbonate kubhekisela kokuqukethwe kwe-magnesium ion, evame ukulawulwa phakathi kuka-40-42%.Okuqukethwe kwe-ion ye-magnesium ephezulu kakhulu noma ephansi kakhulu kuzothinta isilinganiso nokusebenza kwezinto ezibonakalayo ze-electrode.Ngakho-ke, lapho ukhetha i-magnesium carbonate, khetha labo abakhiqizi abanobuchwepheshe obuphezulu bokukhiqiza kanye nezinga lobuchwepheshe.Bangakwazi ukulawula ngokunembile okuqukethwe kwe-magnesium ion ye-magnesium carbonate futhi baqinisekise ikhwalithi yokomisa komkhiqizo nokususwa kokungcola.
- Hlola ukuthi ingabe ukungcola kazibuthe kwe-magnesium carbonate kulawulwa ebangeni eliphansi.Ukungcola kazibuthe kubhekisela ezintweni zensimbi noma izinhlanganisela ezifana nensimbi, i-cobalt, i-nickel, njll., okuzothinta isivinini sokufuduka nokusebenza kahle kwe-lithium ion phakathi kwama-electrode amahle namabi, ukunciphisa amandla kanye nempilo yamabhethri.Ngakho-ke, lapho ukhetha i-magnesium carbonate, khetha leyo mikhiqizo enokungcola kazibuthe okungaphansi kuka-500 ppm (okukodwa esigidini), futhi uyiqinisekise ngamathuluzi okuhlola angochwepheshe.
- Hlola ukuthi usayizi wezinhlayiyana ze-magnesium carbonate uphakathi.Usayizi wezinhlayiyana ze-magnesium carbonate uzothinta i-morphology kanye necrystallinity yezinto ezibonakalayo ze-electrode, bese kuthinta ukusebenza kokushaja nokuqina komjikelezo wamabhethri.Ngakho-ke, lapho ukhetha i-magnesium carbonate, khetha leyo mikhiqizo enosayizi wezinhlayiyana ezincane kanye nosayizi wezinhlayiyana ezifanayo nezinye izinto.Ngokuvamile, usayizi wezinhlayiyana D50 (okungukuthi, usayizi wezinhlayiyana zokusatshalaliswa okuhlanganisiwe okungu-50%) we-magnesium carbonate cishe u-2 microns, i-D90 (okungukuthi, usayizi wezinhlayiyana wokusabalalisa oqoqiwe wama-90%) cishe u-20 microns.
Ngamafuphi, esimweni sokukhula okusheshayo kwemakethe yebhethri ye-lithium, i-magnesium carbonate njengento ebalulekile yebhethri, ikhwalithi yayo ithinta ngokuqondile ukusebenza kanye nekhwalithi yamabhethri e-lithium.Ngakho-ke, lapho sikhetha i-magnesium carbonate, kufanele sikhethe leyo mikhiqizo enokuqukethwe okuyinhloko okuzinzile, ukungcola okuphansi kazibuthe kanye nobukhulu bezinhlayiyana ezimaphakathi ukuze kuqinisekiswe ukusebenza kahle nokusetshenziswa isikhathi eside kwamabhethri e-lithium.
