Peb qhov kev xav tau loj ntawm lub zog cia roj teeb, kev nyab xeeb yog qhov tseem ceeb tshaj plaws
Electrochemical zog cia yog suav tias yog lub ntsiab ntawm lub zog cia nyob rau hauv lub neej yav tom ntej fais fab system, roj teeb thiab PCS yog tus nqi siab tshaj plaws thiab cov teeb meem nyob rau hauv kev lag luam saw, cov tub ntxhais xav tau nyob rau hauv kev ruaj ntseg siab, lub neej ntev thiab tus nqi qis.Ntawm lawv, kev nyab xeeb yog tus yuam sij.Qee cov kws tshaj lij hauv kev lag luam tau hais tias, tam sim no lub tshuab hluav taws xob hluav taws xob khaws cia hluav taws xob tau txhim kho sai, tab sis qhov teeb meem kev nyab xeeb yog lub hauv paus ntawm nws txoj kev loj hlob, Beijing zog cia fais fab nroj tsuag thiab Tesla Australia lub zog cia qhov project ntawm tawg kuj rau lub zog cia kev lag luam. tau suab tswb.
Txog rau qhov kawg no, Cov Lus Qhia Txog Kev Txhim Kho Kev Txhim Kho Lub Zog Tshiab tso rau pem hauv ntej ntawm kev tsim cov qauv kev nyab xeeb thiab kev tswj hwm kev tswj hwm, ntxiv dag zog rau kev tswj hwm kev nyab xeeb hluav taws, nruj me ntsis raws li cov kab hauv qab kev nyab xeeb raws li lub hauv paus ntsiab lus;nyob rau hauv kev nyab xeeb siab, tus nqi qis, kev ntseeg siab, lub neej ntev thiab lwm yam ntawm kev ua tiav ntev;ntxiv dag zog rau kev nyab xeeb ntawm electrochemical zog cia tshuab tshawb fawb thiab lwm yam.National Development and Reform Commission, National Energy Board los teeb tsa lub "Interim Measures for the Safe Management of Electrochemical Energy Storage Stations (Draft)", kuj tau ua rau lub Yim Hli 24th rau lub zej zog rau kev sib tham rau pej xeem, los txhawb kev tswj hwm. ntawm lub zog cia kev ruaj ntseg.
Kev nyab xeeb siab, lub neej ntev, nickel-hlau hydride roj teeb tus nqi tseem ceeb
Tuam Tshoj roj teeb kev lag luam koom haum cov ntaub ntawv qhia tau hais tias nickel-hlau hydride hluav taws xob muaj kev ruaj ntseg, lub neej ntev, nws cov electrode zoo ua los ntawm npib tsib xee spheres, cov khoom siv tsis zoo electrode yog txhawb los ntawm hydrogen cia alloy, belongs rau cov khoom siv ruaj khov, dej electrolyte muaj qhov zoo. nplaim retardant zog, yuav tsis tawg thiab hlawv cov xwm txheej, lub roj teeb monomer zog ceev txog li 140wh / kg;lub voj voog lub neej txog li 3,000, ntiav them thiab tso tawm lub xeev mus txog 10,000 zaug lossis ntau dua;tuaj yeem siv rau ntau tshaj 10,000 zaug;tuaj yeem siv rau ntau tshaj 10,000 zaug.Ntau tshaj 10,000 zaug;tuaj yeem tswj tau tus nqi siab ntawm kev them nyiaj thiab tso tawm hauv -40 ° C ~ 60 ° C ib puag ncig.Toyota HEV tsheb thoob ntiaj teb kev muag khoom tau mus txog ntau dua 18 lab, thiab dav siv nrog nickel-hlau hydride roj teeb, tsis tau muaj ib qho teeb meem ntawm roj teeb combustion, kev nyab xeeb siab ntawm lub roj teeb tau raug kuaj xyuas tag nrho.
Ntxiv mus, lub roj teeb them thiab tso tawm yog kev hloov pauv ntawm cov tshuaj lom neeg thiab hluav taws xob hluav taws xob, qhov kub thiab txias muaj qhov cuam tshuam zoo rau cov tshuaj tiv thaiv.Lub zog txuag hluav taws xob chaw nres tsheb feem ntau yog sab nraum zoov, feem ntau ntawm cov roj teeb muaj kev cuam tshuam los ntawm ib puag ncig thiab qhov kub thiab txias, txwv qhov chaw ntawm cov chaw nres tsheb fais fab thiab ua rau lub luag haujlwm ntawm lub zog cia.Nickel-hlau hydride roj teeb nyob rau hauv qhov kub tsis tshua muaj kub thiab kub kub zoo heev thiab kev ua haujlwm tawm, kom lub zog cia chaw nres tsheb fais fab chaw hloov pauv tau yooj yim, yooj yim dua, kev ua tau zoo tag nrho, uas tau dhau los ua nws txoj kev koom tes hauv kev sib tw ntawm cov roj teeb sib txawv " ntxiv cov ntsiab lus".
Qhov tseeb, nickel-hlau hydride roj teeb nyob rau hauv lub zog cia kev lag luam daim ntawv thov tau ua ntej.2020, nickel-hlau hydride roj teeb lub zog cia lub tuam txhab Nilar los ntawm European Investment Bank 47 lab euros peev.Nws tau nkag siab tias Nilar tab tom tsom mus rau kev tsim hluav taws xob txuas ntxiv txuas ntxiv thiab kev cia khoom, standby lub zog thiab hluav taws xob tsheb them cov ntawv thov, kev nqis peev yog los txhawb lub tuam txhab yuav muab kev koom ua ke rau hauv lub roj teeb rau cov tsev nyob, kev lag luam thiab kev lag luam thiab daim phiaj xwm txheej lossis kev lag luam kev lag luam. .Raws li Frontiers hauv Polymer Science, xib fwb Yi Cui pab neeg ntawm Stanford University tau tsim ib lub roj teeb nickel-hlau hydride (Ni-MH) rau kev siv hluav taws xob loj thiab kev khaws cia, nrog rau qhov zoo ntawm ultra-ntev kev pab cuam lub neej, tsis muaj kev pheej hmoo ntawm hluav taws kub los yog thermal runaway, tsis tas yuav tsum muaj kev saib xyuas niaj hnub, kev coj tus cwj pwm tsis zoo, thiab tus nqi qis.Cui pab pawg yuav tsim ib chav tsav nrog lub peev xwm ntawm 2 megawatts hauv 2021, thiab npaj yuav nthuav dav nws lub peev xwm mus txog 20 npaug ntawm cov nyiaj los ntawm 2022.
