Abanye baphumeze iindlela zokubeka amaxabiso kunye nezivumelwano zekhola ezinqanda ukuvezwa kokuguquguquka kweemarike ngelixa zivumela inzuzo engaphelelanga ekwehleni kwamaxabiso.

Isinyithi se-lithium esicocekileyo sisebenza kakhulu, sivutha ngokuzenzekelayo emoyeni kwaye siphendule ngobudlova ngamanzi. Iityuwa zeLithium zizinzile kwiikhompawundi ze-ionic apho i-lithium sele isabelana neeanions, ibenza bakhuseleke ukuphatha, ukugcina, nokulawula. Kwimixholo yamachiza, olu uzinzo luvumela ulawulo lomlomo kunye nokufunxa okuqikelelweyo. Kwiibhetri,iibhetri ze-lithium ziyatshajwa kwakhonakuxhomekeke ekusebenziseni iityuwa ze-lithium kwi-electrolytes kunentsimbi esulungekileyo, nangona uphando kwi-lithium-i-anode yesinyithi iqhubeleka kwi-{1}}inkqubo yesizukulwana esilandelayo.

Iziphumo ze-Antimanic zivame ukuvela kwiiveki ze-1-2 zokufezekisa amanqanaba e-serum yonyango (0.8-1.2 mmol / L yonyango olunzima). Nangona kunjalo, ukuzinza okupheleleyo kwemizwelo kunye neenzuzo zeprophylactic zifuna iinyanga ze-6-12 zonyango oluhambelanayo. Ngokumalunga ne-30-40% yezigulane zibonisa ukuphucuka okukhulu kwinyanga yokuqala, enye i-20-30% iphendula ngokuthe ngcembe kwiinyanga ze-3-6, ngelixa i-30-40% ibonisa impendulo encinci efuna ezinye iindlela.

Iityuwa zeLithium ngokwazo azitshi, kodwa iibhetri ze-lithium{0}}zinokuba ne-thermal runaway phantsi kweemeko zokuxhatshazwa (i-overcharging, umonakalo womzimba, iisekethe ezimfutshane zangaphakathi). Oku kwenzeka xa amaqondo obushushu angaphakathi edlula i-80{3}}100℃, ukubola kwezinyibilikisi ze-electrolyte kunye nemathiriyeli yesahlukanisi kwi-self{5}}eyomeleza ukusabela kwe-exothermic. Iisistim zala maxesha zolawulo lwebhetri, iifusi ezishushu, kunye{8}}noyilo lwenqanaba lokhuseleko lweseli lunciphise ngokumangalisayo amazinga okusilela ukuya kutsho malunga ne-1 kwisigidi seseli ezili-10 kusetyenziso lwabathengi kwaye nangaphantsi kwiiseli zodidi lwemoto.

Ayizizo zonke iibhetri ze-lithium{{0}ezifumanekayo kwakhona. Iprayimari ({2}}engenakutshajwa kwakhona) iibhetri zelithium zisebenzisa i-metallic lithium anode kunye nekhemistry eyahlukileyo kunelithium etshajwayo{3}}iiseli zeion. Iiseli ze-lithium eziphambili zibonelela ngamandla aphezulu kunye nobomi obude beshelufu kodwa azikwazi ukutshajwa kwakhona. Ibhetri ye-lithium ephinda itshajwe -esebenzisa iityuwa ze-lithium kwi-electrolytes kunye ne-lithium{7}}ikhompawundi zonxibelelwano kwi-electrode, zilawula umbane womthengi kunye nosetyenziso lweemoto ngenxa yokutshajwa kwakhona ngamakhulu okanye amawaka emijikelo.

Unikezelo lwe-dynamics lutshintshe kakhulu ngo-2024-2025. Emva kweminyaka yokubonelela amaxabiso okuqhuba amaxabiso ukuya kwi-78,000/mt lithium carbonate elingana ngasekupheleni kwe-2022, imveliso eyandisiweyo evela e-Australia, eChile, nase-Argentina idale ukugqithiswa, ukuhla kwamaxabiso ukuya kwi-$ 10,500 -11,000 / mt ngoJanuwari 2025. Iiprojekthi ezininzi ezifakwe kwikhomishini yokulibaziseka, kunye nezinye iiprojekthi zokulibaziseka. Ukulungelelaniswa kwakhona kwemarike kuqikelelwa ngo-2026-2027 njengoko ukukhula kwemfuno yesithuthi sombane kuthatha umthamo ogqithisileyo, kunye ne-S&P Global yokuqikelela amaxabiso alinganayo e-lithium carbonate abuyela kwi-15,000-18,000/mt uluhlu ngo-2027-2028.

Ubude bexesha lonyango lufuna uvavanyo lomntu ngamnye. Kwi-bipolar I disorder ene-episodes ezininzi ezinzima, izikhokelo zincoma ukuqhubeka ne-lithium ubuncinane ubuncinane be-2 - iminyaka emi-5 emva kokufumana uxolelo. Izigulana ezininzi zixhamla kunyango olude-lwexesha okanye olungenasiphelo lunikwa isifo esingapheliyo se-bipolar, indalo ephindaphindayo. Ukupheliswa kuthwala umngcipheko omkhulu wokuphinda ubuyele-malunga ne-50% kwiinyanga ezi-6 emva kokuyeka unyango olusebenzayo lwe-lithium. Xa ukupheliswa kufanelekileyo, ukucotha kancinci ngaphezulu kweenyanga ezi-2-4 kunciphisa umngcipheko wokubuyela umva xa kuthelekiswa nokuyeka ngokukhawuleza.

Iityuwa ezininzi ezizezinye zijongana nokungazinzi kwe-LiPF₆'s thermal kunye nobuntununtunu bokufuma: I-LiFSI ibonelela ngozinzo oluphezulu lwe-thermal kunye ne-ionic conductivity kodwa ixabisa i-3{1}}4x ngaphezulu; I-LiTFSI ibonelela ngokusebenza kakuhle kwe-thermal kodwa i-corrodes abaqokeleli bangoku be-aluminium ngaphandle kwezongezo; I-LiBOB iphucula ukhuseleko kodwa ibonisa{3}}ubushushu obuncinane bokusebenza; kunye ne-LiDFOB ibhalansisa iipropathi ezininzi kodwa ifuna ukuhlanganiswa okucokisekileyo. Uphando lwangoku lujolise kwimixube yetyuwa exutyiweyo edibanisa i-LiPF₆ kunye neendlela ezizezinye ezisebenzayo ezifezekisa iinzuzo zokusebenza kwe-synergistic.

Iityuwa zeLithium zikwisikhundla esikhethekileyo sokhathalelo lwamayeza kunye nokuveliswa kwezinto ezintsha kwimizi-mveliso. Kumayeza engqondo, ezi khompawundi zinike uzinzo olusebenzayo lwemo yeminyaka engamashumi asixhenxe, zibonelela ngeenzuzo zokuthintela ukuzibulala ezingahambelaniyo nezinye iindlela nangona zifuna ukubekwa esweni okuphaphileyo. Uluntu lwezonyango luyaqhubeka nokucokisa iiprothokholi zokusetyenziswa, kunye nophando oluqhubekayo lokuhlola usetyenziso lwe-neuroprotective ngaphaya kwe-bipolar disorder.

Kugcino lwamandla, iityuwa ze-lithium zenza ukuba ibhetri etshajwayo iguqule uthutho kunye neziseko zegridi. Itekhnoloji yakhula ukusuka kwi-niche yabathengi be-elektroniki ngeminyaka yoo-1990s ukuya kwizithuthi zombane eziqhelekileyo ezithwele i-60-100 kWh iipakethe zebhetri ngo-2025. Ukuguquguquka kwemarike{6}}kungqinwa ngumjikelo wexabiso ka-2022-2025-kubonisa ukukhula okukhawulezayo kwecandelo kunokukhula okukhawulezileyo kwentlungu engundoqo.

Ukujonga phambili, itekhnoloji ethe ngqo yokutsalwa kwe-lithium ithembisa imveliso ezinzileyo ejongene nokugxekwa kokusingqongileyo kwimisebenzi ye-brine yemveli. -Uphuhliso lwebhetri yelizwe lunokuguqula ukhuseleko kunye nokuxinana kwamandla ngo-2030. Kwezamayeza, ngokuchanekileyo idosi ekhokelwa luvavanyo lwe-pharmacogenomic inokwandisa impendulo yomntu ngelixa unciphisa iziphumo ebezingalindelekanga.

I-chemistry esisiseko ihlala ithe ngqo-i-lithium cations enxulumana nee-anion ezahlukeneyo{1}}kodwa usetyenziso lusuka kwi-neurons nganye ebuchotsheni ukuya kwigridi{2}}isikali sogcino lweenkqubo. Oku kuguquguquka kucacisa ukuba kutheni iimakethi zetyuwa zehlabathi ze-lithium ziqikelelwa ukuba ziphantse zaphinda kathathu ukusuka kwi-9.4 yeebhiliyoni zeedola ngo-2024 ukuya kwi-27.7 yeebhiliyoni zeedola ngo-2033, zinika iimfuno ezahlukeneyo njengokhathalelo lwempilo yengqondo kunye nokunciphisa utshintsho lwemozulu.

Lithium Salts

Iityuwa ze-lithium zizinzile kwiikhompawundi ze-ionic ezisebenza ngeenjongo ezimbini: izizinzi zemo yezoxubo (ikakhulu i-lithium carbonate) kunye nezixhobo ze-electrolyte yebhetri (ikakhulu i-lithium hexafluorophosphate)

Izicelo zonyango zifuna ukujongwa okuncinci konyango (0.6-1.2 mmol / L amanqanaba e-serum) kunye novavanyo oluqhelekileyo lwezintso kunye ne-thyroid, kodwa ukubonelela ngeenzuzo ezingenakulinganiswa zokuzibulala.
