Abaphandi beYunivesithi yaseStanford benza inkqubela phambili enkulu ekuphuhliseni ubuchwepheshe obutsha bokukhupha i-lithium emanzini anetyuwa. Indlela esebenza kakuhle neyonga indalo ijongana nemeko-bume.iingxaki zoxinzelelo lwe-lithiumekukhupheni nasekucubunguleni ngendlela yesintu. Le teknoloji iyaphuculauxinzelelo lwe-lithium brineukucubungula nokwenza kube lula, kubize kancinci kwaye kuhlale ixesha elide kwindalo nge-redox-couple electrolysis (RCE). Le teknoloji intsha inciphisa iindleko ngama-40% kunendlela yokukhupha elawulwayo.
Ngenxa yokwanda kwezithuthi zombane kunye nokugcinwa kwamandla avuselelekayo, imfuno ye-lithium kuzwelonke inyukile kwiminyaka yakutshanje.Uxinzelelo lwe-lithium oreifuna ukufikelela kwinqanaba elithile, emva koko ingasetyenziselwa ibhetri ye-lithium. Uninzi lokukhupha i-lithium luxhomekeke ekukhupheni amanzi amdaka kumachibi amakhulu phantsi kwelanga unyaka okanye ngaphezulu, kushiya isisombululo esityebileyo se-lithium.
Okwangoku, i-lithium idlala indima ebalulekileyo ekuphuculweni kwamandla kwihlabathi liphela ukuya kumandla azinzileyo. Kuqikelelwa ukuba imfuno ye-lithium iya kunyuka ukusuka kwi-0.5 yezigidi zeetoni ze-metric ngo-2021 ukuya kwi-4 yezigidi zeetoni ze-metric ngo-2030. Ukwanda okukhulu kubangelwa kukuthandwa kunye nokusasazwa ngokubanzi kwezithuthi zombane kunye neenkqubo zamandla acocekileyo.
Ngokubanzi, i-lithium ikhona kwi-brine, emanzini olwandle nakwioyile ezikrwada, ngoko keumlinganiselo woxinzelelo lwe-lithiumibalulekile ekukhupheni kwayo, ukufumana ukufundwa okuchanekileyoukuxinana kwe-lithium kwi-brine, uxinano lwe-lithium emanzini olwandle, ukuxinana kwe-lithium kwioyile eluhlaza, ukuxinana kwe-lithium kwiityuwa zentsimi yeoyile.
I-lithium yendabuko ikhutshwa ematyeni ambiweyo, abiza kakhulu, asebenzisa amandla amaninzi kwaye aqhutywa ziikhemikhali ezinobuthi kunokukhupha i-brine. Kule mihla, ukukhupha i-lithium kutshintshele kwi-brine ephumayo echibini letyuwa ngexabiso eliphantsi kunye neendleko eziphezulu zemali kunye nokusingqongileyo. Iimeko zemozulu zizinto ezibalulekileyo ezichaphazela ukusebenza kakuhle kwemveliso, nto leyo ebangela amathandabuzo malunga nokukwazi kweshishini le-lithium ukuhlangabezana neemfuno ezikhulayo.
Iingenelo zeendleko kunye nokusingqongileyo
Le teknoloji intsha ixabisa kancinci ngenxa yeendleko eziphantsi zokwakha nokugcina amachibi amakhulu okukhupha umphunga elangeni. Ngaphezu koko, ukusetyenziswa kombane, amanzi kunye neekhemikhali kuncinci kakhulu kuneendlela ezimbini zangaphambili. Ngokuphepha ukusetyenziswa komhlaba ngokubanzi kunye nokusetyenziswa kwamanzi kweendlela zemveli, indlela ye-RCE ikwanciphisa umngcipheko wemveliso ye-lithium kwindalo.
Ukujonga Phambili
Ukwanda kwendlela ye-REC kuyathembisa nakwindlela yexesha elizayo yezixhobo ezivuselelekayo. Ukukhupha i-lithium ngokuzenzekelayo nangokukrelekrele yindlela engenakuguqulwa, ingakumbi kumgca wonke wemveliso odibeneyo.iimitha zoxinano olusemgceni, izinzwa zenqanaba kunye nee-viscometer.ILonnmeterukuze ufumane izisombululo zokukhupha i-lithium brine ezilungiselelwe kakuhle. Ungafumana iingcebiso zobungcali kwiinjineli zethu. Ungalibali ukucela ikowuteshini yasimahla ngoku!
