Uhlobo olusha lwebhethri olwenziwe ngama-polymer aqhuba ugesi—ngokuyisisekelo ipulasitiki—lungasiza ekwenzeni indawo yokugcina amandla kugridi ishibhile futhi ihlale isikhathi eside, okwenza ukusetshenziswa okukhulu kwamandla avuselelekayo.
Amabhethri, enziwe yinkampani entsha eseBostonI-PolyJoule, inganikeza enye indlela engabizi kakhulu futhi ehlala isikhathi eside esikhundleni samabhethri e-lithium-ion yokugcina ugesi ovela emithonjeni engapheli njengomoya kanye nelanga.
Le nkampani manje iveza imikhiqizo yayo yokuqala. I-PolyJoule yakhe amaseli angaphezu kuka-18,000 futhi yafaka iphrojekthi encane yokuhlola isebenzisa izinto ezingabizi futhi ezitholakala kabanzi.
Ama-polymer aqhubayo asetshenziswa yi-PolyJoule kuma-electrode ayo ebhethri athatha indawo ye-lithium kanye ne-lead evame ukutholakala emabhethri. Ngokusebenzisa izinto ezingadalwa kalula ngamakhemikhali ezimboni atholakala kabanzi, i-PolyJoule igwema lokhuukucindezelwa kokunikezwaizinto ezibhekene nazo ezifana ne-lithium.
I-PolyJoule yaqalwa oprofesa be-MIT uTim Swager no-Ian Hunter, abathole ukuthi ama-polymer aqhubayo akhetha amabhokisi athile okhiye wokugcina amandla. Angabamba ukushaja isikhathi eside futhi ashaje ngokushesha. Asebenza kahle futhi, okusho ukuthi agcina ingxenye enkulu kagesi ogeleza kuwo. Njengoba kuyipulasitiki, izinto zokwakha nazo zishibhile ukuzikhiqiza futhi ziqinile, zibamba ukuvuvukala nokuncipha okwenzeka ebhethri njengoba lishaja futhi likhipha.
Inkinga eyodwa enkulu ukuthiukuminyana kwamandlaAmabhethri amakhulu ngokuphindwe kabili kuya kahlanu kunesistimu ye-lithium-ion enamandla afanayo, ngakho inkampani yanquma ukuthi ubuchwepheshe bayo buzofaneleka kangcono ezinhlelweni zokusebenza ezimile njengesitoreji segridi kunasezimotweni zikagesi noma ezimotweni, kusho i-CEO ye-PolyJoule u-Eli Paster.
Kodwa ngokungafani namabhethri e-lithium-ion asetshenziswa ngaleyo njongo manje, izinhlelo ze-PolyJoule azidingi noma yiziphi izinhlelo zokulawula izinga lokushisa ezisebenzayo ukuqinisekisa ukuthi azishisi ngokweqile noma zibambe umlilo, uyanezela. “Sifuna ukwenza ibhethri eliqinile ngempela, elingabizi kakhulu elihamba yonke indawo. Ungayishaya noma kuphi futhi akudingeki ukhathazeke ngayo,” kusho uPaster.
Ama-polymer aqhubayo angagcina esengumdlali omkhulu ekugcineni igridi, kodwa ukuthi lokho kuyenzeka yini cishe kuzoncika ekutheni inkampani ingakhulisa ubuchwepheshe bayo ngokushesha kangakanani, futhi okubaluleke kakhulu, ukuthi amabhethri abiza malini, kusho uSusan Babinec, ohola uhlelo lokugcina amandla e-Argonne National Lab.
Abanyeucwaningoikhomba ku-$20 nge-kilowatt-hora yokugcina njengomgomo wesikhathi eside ongasisiza sifinyelele ukwamukelwa kwamandla avuselelekayo okungu-100%. Kuyingqophamlando ukuthi ezinye izindlela ezihlukileamabhethri okugcina igridikugxilwe kukho. I-Form Energy, ekhiqiza amabhethri anomoya wensimbi, ithi ingafinyelela lowo mgomo emashumini eminyaka ezayo.
I-PolyJoule ingase ingakwazi ukuthola izindlekolokho okuphansi", kuvuma uPaster. Okwamanje ihlose u-$65 nge-kilowatt-hora yokugcina izinhlelo zayo, icabanga ukuthi amakhasimende ezimboni kanye nezikhungo zikagesi bangase bazimisele ukukhokha leyo ntengo ngoba imikhiqizo kufanele ihlale isikhathi eside futhi kube lula futhi kushibhile ukuyinakekela.
Kuze kube manje, kusho uPaster, inkampani igxile ekwakheni ubuchwepheshe obulula ukubukhiqiza. Isebenzisa ikhemistri yokukhiqiza esekwe emanzini futhi isebenzisa imishini etholakala kwezentengiselwano ukuhlanganisa amaseli ayo ebhethri, ngakho ayidingi izimo ezikhethekile ngezinye izikhathi ezidingekayo ekukhiqizeni amabhethri.
Akukacaci ukuthi yikuphi ukwakheka kwebhethri okuzophumelela ekugcineni kwegridi. Kodwa amapulasitiki ePolyJoule asho ukuthi sekuvele inketho entsha.
