Lub zog cia yuav yog qhov loj ntawm lub zog rov ua dua tshiab. Hluav taws xob tsis zoo ib yam li cheese lossis mov ci. Nws yuav tsum tau siv ntau dua lossis ntau nrawm lossis nws ploj mus ib txhis. Kev hais lus yog kev hais lus zoo kev lag luam uas siv hluav taws xob los piav qhia tus txheej txheem ntawm muag hluav taws xob ntau heev. Qee qhov xwm txheej, tus neeg tsim khoom hluav taws xob yuav tsum them cov neeg siv hluav taws xob lossis cov xa tawm kom rho nws tawm ntawm lawv txhais tes. Muab cov khoom tso tseg lossis them nyiaj rau lwm tus kom tshem nws yog txoj kev lag luam tus qauv tsis zoo. Koj tsis tuaj yeem yuav cov txiv av liab rau 10 xees ib daim, muag lawv rau ib daus las ib nrab, thiab vam tias yuav ua tau zoo raws cov ntim.

Lub sijhawm tam sim no, nws muaj peb txoj hauv kev khaws hluav taws xob - lithium ion roj teeb, pumped hydro cia, lossis roj teeb redox ntws. Muaj qee lwm cov thev naus laus zis tawm zoo li huab cua ntawm huab cua lossis tshem tawm cov pawg ntawm cov pob zeb loj loj nyob ib puag ncig tab sis lawv nyob ntawm cov npoo ntawm lub zog cia.

Lithium ion roj teeb tau zoo heev ntawm kev khaws cia cov hluav taws xob tab sis lawv tseem kim heev, txawm tias cov nqi tau nqis qis dua 5 xyoos dhau los. Ib qho ntawm lawv lub zog yog lawv muaj peev xwm teb tau cov kev hloov hauv zaus lossis voltage nrawm. Pumped hydro kuj tseem zoo heev rau kev khaws lub zog tab sis nws yuav siv sij hawm ntau ntawm cov vaj tsev thiab tsis tuaj yeem muaj kev cuam tshuam sai li roj teeb.

Redox ntws roj teeb muaj qhov sib txawv tshwj xeeb. Tus nqi ntawm lub zog thiab cov hluav taws xob uas lawv khaws tau tuaj yeem tsim kho kom tau raws li qhov xav tau ntawm kev siv tshwj xeeb. Lawv kuj muaj hneev taw me me piv rau cov roj teeb thiab pumped hydro, yog li lawv tuaj yeem tso rau yuav luag txhua qhov chaw - nyob hauv nroog txwv tsis pub dhau, txuas ntxiv rau kev txuas lub zog tauj dua tshiab, lossis hauv cov chaw hloov hluav taws xob. Lawv tuaj yeem khaws hluav taws xob rau lub sijhawm ntev, uas txhais tau hais tias hluav taws xob tau tsim los ntawm cov kab hluav taws xob hnub ci hauv lub caij ntuj sov tuaj yeem txuag rau qhov txias thiab huab cua hnub caij ntuj no. Lub zog ntom ntom ntawm cov roj teeb ntws hluav taws xob, tshwj xeeb tshaj yog polysulphide / huab cua huab cua, yog li ntawm 500 zaus siab dua li cov twj tso kua mis hydropric cia.

Txawm hais tias lawv tau zoo, kom txog rau tam sim no cov roj teeb redox ntws tsis tau muaj nuj nqis tseem ceeb dua roj teeb thiab muaj lub sijhawm ua haujlwm pabcuam luv. Tab sis cov kws tshawb fawb ntawm Warwick University hauv tebchaws Askiv, kev koom tes nrog cov npoj yaig ntawm Imperial College London, hais tias lawv tau pom txoj hauv kev txo qis cov roj teeb redox txaus rau to 20 ib kWh lossis tsawg dua siv cov khoom siv pheej yig xws li manganese thiab sulfur uas tau pom nyob rau hauv abundance xwm. Lawv thov cov nqi ntawm cov ntaub ntawv rau lawv cov roj teeb tshiab yog kwv yees li 1/30 uas ntawm cov ntaub ntawv xav tau rau lub roj teeb lithium ion, uas tej zaum yuav siv cov khoom kim xws li cobalt. Lawv cov kev tshawb fawb tau luam tawm tsis ntev los no hauv Cov Ntawv Xov Xwm Cov Khoom Siv & Kev cuam tshuam.

Dab tsi ua rau cov roj teeb tshiab yog li tshwj xeeb? Raws li Kev Tshawb Fawb Txhua Hnub, thev naus laus zis thev naus laus zis nrog cov roj hluav taws xob nrog kev sib txig ntawm cov khoom hluav taws xob - manganese lossis sulfur - los ntawm qhov yooj yim thiab tsis tau muaj txiaj ntsig electrophoretic deposition ntawm nano-carbon additives (nitrogen-doped graphene) uas txhim kho cov electrode durability thiab kev ua tau zoo hauv acidic lossis alkaline chaw zoo heev. Yog tias cov lus "electrophoretic deposition ntawm nano-carbon ntxiv" ua rau koj lub qhov muag ci, koj yuav tsum tsis txhob nrhiav txoj haujlwm ua ib tus kws tshawb fawb txog kev tshawb fawb.

Dr Barun Chakrabarti, ib tug ntawm cov sau phau ntawv hais tias, "EPD txheej txheem no tsis yog yooj yim xwb tab sis tseem txhim kho txoj kev ua tau zoo ntawm peb cov kev lag luam sib txawv roj txaus kom thiaj li ua rau lawv muaj peev xwm nthuav dav rau kev lag luam saws mus rau daim phiaj siv hluav taws xob cia." Yog tias cov kws tshawb nrhiav hais txog kev siv lub ntiaj teb tiag tiag, lub ntiaj teb kev txuag hluav taws xob thiab lub zog cia tsuas yog siv mus ib kauj ruam loj rau tom ntej.
