Ƙara koyo game da fasahohin maye gurbin guda uku

Dr. Zhang ya bayyana wadannan fasahohin fasahar batura masu zafi guda uku, wadanda yawancinsu har yanzu suna cikin dakin gwaje-gwaje. Duk da cewa har yanzu akwai sauran rina a kaba don samar da kasuwanci, amma mun yi imanin cewa saurin bunƙasa samfuran lantarki ta wayar hannu zai ƙara tsadar batura, wanda ko shakka babu zai ƙara rushewar fasaha da kasuwanci.

Wayoyin hannu, Allunan, da na’urorin da za a iya sawa duk suna haɓaka, amma baturin yana ɗaya daga cikin kuncinsu. Yawancin sabbin masu amfani da wayoyin komai da ruwan suna takaici da rayuwar batir. A baya dai sun yi amfani da wayoyinsu na tsawon kwanaki 4 zuwa 7, amma a kullum sai sun yi caji.

Batura lithium sune mafi yawan al’ada, waɗanda masu tallafawa da masana’antun masana’antu ke so, amma a cikin dogon lokaci, ƙila ba za su isa su ninka ƙarfin ƙarfinsu ba. A cikin wayoyi masu wayo, mutane suna ciyar da ƙarin lokaci akan layi, da sauri, kuma kwakwalwan kwamfuta dole ne su kasance cikin sauri. A lokaci guda, duk da haɓakawa a cikin duk matakan ceton makamashi, allon yana ƙaruwa kuma farashin makamashi yana ƙaruwa. Dr. Zhang Yuegang, kwararre kan baturi na kasa da kasa a kwalejin kimiyyar kasar Sin, ya bayyana cewa, batir mai caji na mako guda na wayoyin salula na zamani ba zai wadatar ba.

Yawan makamashi yana ɗaya daga cikin mahimman alamomi don auna ingancin baturi, kuma dabarunsa shine adana ƙarin kuzari a cikin ƙananan batura da ƙarami. Misali, batirin lithium na BYD, wanda aka ƙididdige su ta nauyi da girma, a halin yanzu suna cinye awa 100-125 watt-awa/kg da 240-300 watt-hours/lita bi da bi. Batirin kwamfutar tafi-da-gidanka na Panasonic da aka yi amfani da shi a cikin motar lantarki ta Tesla Model S yana da ƙarfin ƙarfin awoyi 170 a kowace kilogram. A cikin rahotonmu da ya gabata, kamfanin Enevate na Amurka ya inganta bayanan cathode don ƙara yawan kuzarin batir lithium da fiye da 30%.

Don ƙara ƙarfin ƙarfin batura da yawa, dole ne ku dogara da fasahar baturi na gaba. Zhang Yuegang ya gabatar da mu ga fasahohin batir masu zafi guda uku masu zuwa, wadanda yawancinsu har yanzu suna cikin dakin gwaje-gwaje. Duk da cewa har yanzu da sauran rina a kaba don samar da kasuwanci, amma mun yi imanin cewa saurin bunkasuwar kayayyakin lantarki ta wayar salula zai kara tsadar batura, wanda hakan zai kara saurin durkushewar fasaha da kasuwanci.

Batirin Lithium Sulfur

Batirin lithium-sulfur baturi ne na lithium mai dauke da sulfur a matsayin tabbataccen lantarki da lithium na karfe a matsayin wutar lantarki mara kyau. Matsakaicin adadin kuzarinsa ya kai kusan sau 5 na batirin lithium, kuma har yanzu yana cikin farkon matakan haɓakawa.

A halin yanzu, batirin lithium-sulfur sabon ƙarni ne na batir lithium, waɗanda suka shiga fagen binciken dakin gwaje-gwaje da kudade na share fage daban-daban, kuma suna da kyakkyawan fata na kasuwanci.

Duk da haka, batirin lithium-sulfur suma suna fuskantar wasu ƙalubale na fasaha, musamman ma abubuwan da ke tattare da sinadarai na bayanan gurɓataccen lantarki na baturi da rashin kwanciyar hankali na ƙarfe na lithium, wanda shine babban gwajin lafiyar baturi. Bugu da ƙari, abubuwa da yawa kamar kwanciyar hankali, dabara, da fasaha suna fuskantar ƙalubalen da ba a sani ba.

A halin yanzu, a Birtaniya da Amurka, kungiyoyi fiye da daya suna nazarin baturan lithium-sulfur, kuma wasu kamfanoni sun bayyana cewa za su kaddamar da irin wannan batu a wannan shekara. A dakin gwaje-gwajensa na Berkeley, yana kuma nazarin batirin lithium-sulfur. A cikin yanayin gwaji mai fa’ida, bayan fiye da zagayawa 3,000, an samu gamsasshen sakamako.

batirin iska lithium

Lithium-air baturi baturi ne wanda lithium shine tabbataccen lantarki kuma iskar oxygen a cikin iska shine rashin wutar lantarki. The theoretical energy density na lithium anode ya kusan sau 10 na batirin lithium, saboda tabbataccen ƙarfin lantarki na ƙarfe lithium yana da haske sosai, kuma tabbataccen ingantaccen lantarki abu oxygen yana wanzuwa a cikin yanayin yanayi kuma ba a adana shi a cikin baturi.

Batura Li-air suna fuskantar ƙarin ƙalubale na fasaha. Baya ga amintaccen kiyayewar lithium na ƙarfe, sinadarin lithium oxide da aka samar ta hanyar iskar oxygen ɗin ya yi tsayin daka, kuma ana iya kammala amsawa da ragewa kawai tare da taimakon mai kara kuzari. Bugu da kari, batun hawan batir bai warware ba.

Idan aka kwatanta da baturan lithium-sulfur, binciken da ake yi kan batir lithium-air har yanzu yana kan matakin farko, kuma babu wani kamfani da ya sanya su cikin ci gaban kasuwanci.

Magnesium baturi

Batir na Magnesium baturi ne na farko tare da magnesium azaman wutar lantarki mara kyau da wani ƙarfe ko oxide mara ƙarfe a matsayin tabbataccen lantarki. Idan aka kwatanta da baturan lithium, baturan magnesium ion suna da mafi kyawun kwanciyar hankali da tsawon rayuwar sabis.
