Ib hom roj teeb tshiab ua los ntawm cov polymers uas ua hluav taws xob tau—feem ntau yog yas—yuav pab ua kom lub zog khaws cia rau ntawm lub grid pheej yig dua thiab ruaj khov dua, ua rau siv tau lub zog rov ua dua tshiab tau zoo dua.
Cov roj teeb, ua los ntawm Boston-based startupPolyJoule, tuaj yeem muab lwm txoj hauv kev pheej yig dua thiab siv tau ntev dua rau cov roj teeb lithium-ion rau kev khaws hluav taws xob los ntawm cov chaw tsis tu ncua xws li cua thiab hnub ci.
Lub tuam txhab tam sim no tab tom qhia nws cov khoom thawj zaug. PolyJoule tau tsim ntau dua 18,000 lub hlwb thiab teeb tsa ib qho project me me siv cov khoom siv pheej yig thiab muaj ntau.
Cov polymers conductive uas PolyJoule siv hauv nws cov electrodes roj teeb hloov cov lithium thiab lead feem ntau pom muaj nyob rau hauv roj teeb. Los ntawm kev siv cov ntaub ntawv uas tuaj yeem tsim tau yooj yim nrog cov tshuaj lom neeg muaj ntau, PolyJoule zam qhovkev muab khoomcov ntaub ntawv xws li lithium.
PolyJoule tau pib los ntawm cov xibfwb MIT Tim Swager thiab Ian Hunter, uas pom tias cov polymers conductive tau ua tiav qee qhov tseem ceeb rau kev khaws cia lub zog. Lawv tuaj yeem tuav lub zog tau ntev thiab them sai. Lawv kuj ua haujlwm tau zoo, txhais tau tias lawv khaws cia ib feem loj ntawm cov hluav taws xob uas ntws mus rau hauv lawv. Vim yog yas, cov ntaub ntawv kuj pheej yig rau kev tsim khoom thiab ruaj khov, tuav tau qhov o thiab kev sib cog lus uas tshwm sim hauv lub roj teeb thaum nws them thiab tso tawm.
Ib qho teeb meem loj yoglub zog ceevCov roj teeb pob yog ob mus rau tsib npaug loj dua li lub lithium-ion system uas muaj peev xwm zoo sib xws, yog li lub tuam txhab txiav txim siab tias nws cov thev naus laus zis yuav zoo dua rau cov ntawv thov ruaj khov xws li kev khaws cia grid dua li hauv cov khoom siv hluav taws xob lossis tsheb, PolyJoule CEO Eli Paster hais.
Tab sis tsis zoo li cov roj teeb lithium-ion siv rau lub hom phiaj ntawd tam sim no, PolyJoule cov kab ke tsis xav tau cov kab ke tswj kub kom paub tseeb tias lawv tsis kub dhau lossis kub hnyiab, nws hais ntxiv. "Peb xav ua lub roj teeb uas muaj zog heev, pheej yig uas mus txhua qhov chaw. Koj tuaj yeem muab nws tso rau txhua qhov chaw thiab koj tsis tas yuav txhawj txog nws," Paster hais.
Cov polymers uas muaj conductive yuav ua tau ib qho tseem ceeb hauv kev khaws cia hluav taws xob, tab sis seb qhov ntawd puas yuav tshwm sim yuav nyob ntawm seb lub tuam txhab tuaj yeem nthuav dav nws cov thev naus laus zis sai npaum li cas thiab, qhov tseem ceeb, cov roj teeb raug nqi ntau npaum li cas, Susan Babinec, uas yog tus thawj coj ntawm qhov kev pab cuam khaws cia hluav taws xob ntawm Argonne National Lab hais.
Qee yamkev tshawb fawbtaw qhia rau $ 20 ib kilowatt-teev ntawm kev khaws cia ua lub hom phiaj ntev uas yuav pab peb ua tiav 100% kev siv hluav taws xob rov ua dua tshiab. Nws yog ib qho tseem ceeb uas lwm txoj hauv kev xaivcov roj teeb cia hluav taws xoblawv tsom mus rau. Form Energy, uas tsim cov roj teeb hlau-cua, hais tias nws tuaj yeem ua tiav lub hom phiaj ntawd hauv kaum xyoo tom ntej.
PolyJoule tej zaum yuav tsis tau txais cov nqiqis ntawd, Paster lees paub. Tam sim no nws tab tom tsom mus rau $ 65 ib kilowatt-teev ntawm kev khaws cia rau nws cov kab ke, vim tias cov neeg siv khoom lag luam thiab cov chaw muab hluav taws xob yuav kam them tus nqi ntawd vim tias cov khoom yuav tsum siv tau ntev dua thiab yooj yim dua thiab pheej yig dua rau kev saib xyuas.
Txog tam sim no, Paster hais tias, lub tuam txhab tau tsom mus rau kev tsim cov thev naus laus zis uas yooj yim rau kev tsim khoom. Nws siv cov tshuaj lom neeg tsim khoom uas ua los ntawm dej thiab siv cov tshuab muaj muag hauv khw los sib sau ua ke nws cov roj teeb, yog li nws tsis xav tau cov xwm txheej tshwj xeeb uas qee zaum xav tau hauv kev tsim roj teeb.
Tseem tsis tau meej tias cov tshuaj lom neeg ntawm lub roj teeb yuav yeej dab tsi hauv kev khaws cia hluav taws xob. Tab sis PolyJoule cov yas txhais tau tias muaj kev xaiv tshiab tau tshwm sim.
