Batire yatsopano yopangidwa kuchokera ku ma polima oyendetsera magetsi—makamaka pulasitiki—ingathandize kupangitsa kuti malo osungira magetsi pa gridi akhale otsika mtengo komanso olimba, zomwe zimathandiza kuti magetsi ongowonjezedwanso agwiritsidwe ntchito bwino.
Mabatire, opangidwa ndi kampani yoyambira ku BostonPolyJoule, ingapereke njira yotsika mtengo komanso yokhalitsa m'malo mwa mabatire a lithiamu-ion yosungira magetsi kuchokera kuzinthu zosakhalitsa monga mphepo ndi dzuwa.
Kampaniyo tsopano ikuwulula zinthu zake zoyamba. PolyJoule yamanga ma cell opitilira 18,000 ndikuyika pulojekiti yaying'ono yoyesera pogwiritsa ntchito zipangizo zotsika mtengo komanso zomwe zimapezeka kwambiri.
Ma polima oyendetsera magetsi omwe PolyJoule amagwiritsa ntchito mu ma electrode ake a batri amalowa m'malo mwa lithiamu ndi lead zomwe zimapezeka m'mabatire. Pogwiritsa ntchito zipangizo zomwe zingapangidwe mosavuta ndi mankhwala omwe amapezeka m'mafakitale ambiri, PolyJoule imapewakufinya kokwanirazinthu zoyang'ana nkhope monga lithiamu.
PolyJoule idayambitsidwa ndi aphunzitsi a MIT Tim Swager ndi Ian Hunter, omwe adapeza kuti ma polima oyendetsera magetsi amaika zinthu zina zofunika pakusungira mphamvu. Amatha kusunga mphamvu kwa nthawi yayitali ndikuyika mphamvu mwachangu. Amagwiranso ntchito bwino, zomwe zikutanthauza kuti amasunga gawo lalikulu la magetsi omwe amalowa m'mafakitale. Popeza ndi pulasitiki, zipangizozi ndizotsika mtengo kupanga komanso zolimba, zomwe zimateteza kutupa ndi kupindika komwe kumachitika mu batire pamene ikuchaja ndi kutulutsa.
Vuto limodzi lalikulu ndikuchuluka kwa mphamvuMa batirewa ndi akulu kawiri kapena kasanu kuposa makina a lithiamu-ion okhala ndi mphamvu yofanana, kotero kampaniyo idaganiza kuti ukadaulo wake ungakhale woyenera kwambiri pazinthu zosagwiritsidwa ntchito monga kusungira gridi kuposa zamagetsi kapena magalimoto, akutero CEO wa PolyJoule, Eli Paster.
Koma mosiyana ndi mabatire a lithiamu-ion omwe amagwiritsidwa ntchito pa cholinga chimenecho masiku ano, makina a PolyJoule safuna makina owongolera kutentha kuti atsimikizire kuti sakutentha kwambiri kapena kugwira moto, akuwonjezera. "Tikufuna kupanga batire yolimba kwambiri, yotsika mtengo yomwe imangopita kulikonse. Mutha kuyiyika kulikonse ndipo simuyenera kuda nkhawa nayo," akutero Paster.
Ma polima oyendetsera magetsi akhoza kukhala gawo lalikulu pakusungira magetsi, koma ngati zimenezo zingachitike mwina zidzadalira momwe kampani ingakulitsire ukadaulo wake mwachangu komanso, chofunika kwambiri, mtengo wa mabatirewo, akutero Susan Babinec, yemwe akutsogolera pulogalamu yosungira magetsi ku Argonne National Lab.

Ndi chinthu chofunika kwambiri chomwe njira zina zosungiramo zinthu zinamabatire osungira gridiKampani ya Form Energy, yomwe imapanga mabatire achitsulo ndi mpweya, ikunena kuti ikhoza kukwaniritsa cholinga chimenecho m'zaka zikubwerazi.
PolyJoule mwina sangathe kupeza ndalamaotsika amenewoPaster akuvomereza. Pakadali pano ikufuna kusungitsa $65 pa kilowatt-ola imodzi ya makina ake, poganiza kuti makasitomala amafakitale ndi makampani opanga magetsi angakhale okonzeka kulipira mtengo umenewo chifukwa zinthuzo ziyenera kukhala nthawi yayitali komanso zosavuta komanso zotsika mtengo kusamalira.
Paster akuti pakadali pano, kampaniyo yayang'ana kwambiri pakupanga ukadaulo wosavuta kupanga. Imagwiritsa ntchito mankhwala opangira zinthu pogwiritsa ntchito madzi ndipo imagwiritsa ntchito makina ogulitsa kuti ipange mabatire ake, kotero sifunikira zinthu zapadera zomwe nthawi zina zimafunika popanga mabatire.
Sizikudziwikabe kuti ndi batire iti yomwe ingapambane posungira gridi. Koma mapulasitiki a PolyJoule akutanthauza kuti pali njira yatsopano yomwe yatulukira.
