Uhlobo olutsha lwebhetri olwenziwe ngeepolymers eziqhuba umbane—ngokusisiseko iplastiki—lunokunceda ukwenza ukugcinwa kwamandla kwigridi kube kungabizi kakhulu kwaye kuhlale ixesha elide, nto leyo evumela ukusetyenziswa ngakumbi kwamandla ahlaziyekayo.
Iibhetri, ezenziwe yinkampani entsha eseBostonI-PolyJoule, inokubonelela ngenye indlela engabizi kakhulu nehlala ixesha elide endaweni yeebhetri ze-lithium-ion yokugcina umbane ovela kwimithombo ephumayo efana nomoya kunye nelanga.
Le nkampani ngoku ityhila iimveliso zayo zokuqala. I-PolyJoule yakhe iiseli ezingaphezu kwe-18,000 kwaye ifake iprojekthi encinci yovavanyo isebenzisa izixhobo ezingabizi kakhulu nezifumaneka ngokubanzi.
Iipolymers eziqhubayo ezisetyenziswa yiPolyJoule kwii-electrodes zayo zebhetri zithatha indawo ye-lithium kunye ne-lead ezifumaneka kwiibhetri. Ngokusebenzisa izinto ezinokwenziwa ngokulula ngeekhemikhali zoshishino ezifumaneka ngokubanzi, iPolyJoule iyakuphephaukucudiswa kokubonelelaizinto ezijongene nazo ezifana ne-lithium.
I-PolyJoule yaqalwa ngooprofesa be-MIT uTim Swager kunye no-Ian Hunter, abafumanise ukuba ii-polymers eziqhubayo zibeka uphawu kwiibhokisi ezithile zokugcina amandla. Zingagcina itshaja ixesha elide kwaye zitshaje ngokukhawuleza. Zikwasebenza kakuhle, oko kuthetha ukuba zigcina inxalenye enkulu yombane ohamba kuzo. Ekubeni ziyiplastiki, izixhobo zikwabiza kancinci ukuvelisa kwaye ziqinile, zibamba ukudumba nokufinyela okwenzeka kwibhetri njengoko itshaja kwaye ikhupha.
Ingxaki enkulu kukubauxinano lwamandlaIipakethi zebhetri zinkulu ngokuphindwe kabini ukuya kahlanu kunenkqubo ye-lithium-ion enomthamo ofanayo, ngoko ke inkampani igqibe kwelokuba ubuchwepheshe bayo buya kufaneleka ngakumbi kwizicelo ezisisigxina ezifana nokugcina igridi kunakwii-elektroniki okanye iimoto, utshilo umphathi wePolyJoule u-Eli Paster.
Kodwa ngokungafaniyo neebhetri ze-lithium-ion ezisetyenziselwa loo njongo ngoku, iinkqubo zePolyJoule azidingi naziphi na iinkqubo zokulawula ubushushu ezisebenzayo ukuqinisekisa ukuba azishushu kakhulu okanye azibambi umlilo, wongeza athi: “Sifuna ukwenza ibhetri eqinileyo nengabizi kakhulu ehamba yonke indawo. Ungayibetha naphi na kwaye akufuneki ukhathazeke ngayo,” utshilo uPaster.
Iipolymers eziqhubayo zingaba yinxalenye ebalulekileyo yokugcina igridi, kodwa ukuba oko kuyenzeka na kuya kuxhomekeka ekubeni inkampani ingayiphucula ngokukhawuleza kangakanani iteknoloji yayo, kwaye okubaluleke kakhulu, ukuba iibhetri zibiza malini, utshilo uSusan Babinec, okhokela inkqubo yokugcina amandla kwiArgonne National Lab.
Ezinyeuphandoikhomba kwi-$20 nge-kilowatt-yure yokugcina njengenjongo yexesha elide eya kusinceda sifikelele kwi-100% yokwamkelwa kwamandla ahlaziyekayo. Linyathelo elibalulekileyo elithathwa zezinye iindlela.iibhetri zokugcina igridizigxile kuzo. I-Form Energy, evelisa iibhetri ze-iron-air, ithi ingafikelela kuloo njongo kwiminyaka ezayo.
I-PolyJoule isenokungakwazi ukufumana iindlekoelo liphantsiUPaster uyavuma. Okwangoku ijolise kwi-$65 nge-kilowatt-yure yokugcina iinkqubo zayo, iqiqa ngelithi abathengi bemizi-mveliso kunye neenkonzo zombane basenokuvuma ukuhlawula elo xabiso kuba iimveliso kufuneka zihlale ixesha elide kwaye kube lula kwaye kube nexabiso eliphantsi ukuzigcina.
UPaster uthi okwangoku, inkampani igxile ekwakheni iteknoloji elula ukuyenza. Isebenzisa ikhemistri yokuvelisa esekwe emanzini kwaye isebenzisa oomatshini abathengiswayo ukuhlanganisa iiseli zayo zebhetri, ngoko ke ayifuni iimeko ezikhethekileyo ngamanye amaxesha ezifunekayo ekwenzeni iibhetri.
Akukacaci ukuba yeyiphi ikhemikhali yebhetri eya kuphumelela kwindawo yokugcina igridi. Kodwa iiplastiki zePolyJoule zithetha ukuba kuye kwavela ukhetho olutsha.
