Peb qhov kev xav tau tseem ceeb ntawm lub roj teeb cia hluav taws xob, kev nyab xeeb yog qhov tseem ceeb tshaj plaws
Kev khaws cia hluav taws xob electrochemical yog suav hais tias yog hom kev khaws cia hluav taws xob tseem ceeb hauv lub zog yav tom ntej, roj teeb thiab PCS yog tus nqi siab tshaj plaws thiab cov teeb meem hauv kev lag luam, qhov kev thov tseem ceeb yog kev nyab xeeb siab, lub neej ntev thiab tus nqi qis. Ntawm lawv, kev nyab xeeb yog qhov tseem ceeb. Qee cov kws tshaj lij hauv kev lag luam hais tias, tam sim no lub zog cia hluav taws xob electrochemical tab tom txhim kho sai, tab sis qhov teeb meem kev nyab xeeb yog qhov tsis ruaj khov ntawm nws txoj kev loj hlob loj, Beijing lub zog cia hluav taws xob thiab Tesla Australia qhov project khaws cia hluav taws xob ntawm qhov tawg kuj rau kev lag luam khaws cia hluav taws xob tau ua lub tswb ceeb toom.
Txog qhov kawg no, Cov Lus Qhia Txog Kev Ua Kom Sai Sai Kev Txhim Kho Kev Khaws Cia Zog Tshiab tau muab tso rau pem hauv ntej los tsim cov qauv kev nyab xeeb thiab kev tswj hwm, txhawb nqa kev tswj hwm kev nyab xeeb hluav taws, ua raws li cov ntsiab lus tseem ceeb ntawm kev nyab xeeb; hauv kev nyab xeeb siab, tus nqi qis, kev ntseeg siab siab, lub neej ntev thiab lwm yam ntawm kev nce qib ntev; txhawb nqa kev nyab xeeb ntawm kev tshawb fawb txog kev siv tshuab khaws cia hluav taws xob thiab lwm yam. Pawg Neeg Saib Xyuas Kev Txhim Kho thiab Kev Hloov Kho Hauv Tebchaws, Pawg Neeg Saib Xyuas Zog Hauv Tebchaws los npaj cov ntawv sau ntawm "Cov Kev Ntsuas Ib Ntus rau Kev Tswj Xyuas Kev Nyab Xeeb ntawm Chaw Khaws Cia Hluav Taws Xob Hluav Taws Xob (Draft)", kuj tau muab rau lub zej zog rau kev sib tham rau pej xeem thaum Lub Yim Hli 24, los txhawb nqa kev tswj hwm kev nyab xeeb ntawm kev khaws cia hluav taws xob.
Kev nyab xeeb siab, lub neej ntev, nickel-hlau hydride roj teeb nqi tseem ceeb
Cov ntaub ntawv los ntawm Tuam Tshoj Lub Koom Haum Kev Lag Luam Roj Teeb qhia tau tias nickel-hlau hydride hluav taws xob muaj kev ruaj ntseg siab, lub neej ntev, nws cov electrode zoo ua los ntawm nickel spheres, cov khoom siv electrode tsis zoo yog txhawb nqa los ntawm hydrogen cia alloy, yog cov khoom ruaj khov, dej electrolyte muaj cov khoom zoo hluav taws kub, yuav tsis tawg thiab hlawv cov xwm txheej, lub roj teeb monomer zog ceev txog li 140wh / kg; lub neej voj voog txog li 3,000, lub xeev them thiab tso tawm tsawg txog li 10,000 zaug lossis ntau dua; tuaj yeem siv ntau dua 10,000 zaug; tuaj yeem siv ntau dua 10,000 zaug. Ntau dua 10,000 zaug; tuaj yeem tswj tus nqi siab ntawm kev them thiab tso tawm hauv -40 ° C ~ 60 ° C ib puag ncig. Toyota HEV tsheb muag thoob ntiaj teb tau mus txog ntau dua 18 lab, thiab dav dav nruab nrog nickel-hlau hydride roj teeb, tsis tau muaj ib rooj plaub ntawm cov roj teeb hlawv cov xwm txheej, kev nyab xeeb siab ntawm lub roj teeb tau raug txheeb xyuas tag nrho.
Tsis tas li ntawd xwb, kev them thiab tso roj teeb yog kev hloov pauv ntawm lub zog tshuaj lom neeg thiab lub zog hluav taws xob, qhov kub thiab txias muaj kev cuam tshuam loj heev rau cov tshuaj lom neeg. Cov chaw khaws hluav taws xob feem ntau nyob sab nraum zoov, feem ntau hom roj teeb raug cuam tshuam los ntawm ib puag ncig thiab qhov kub thiab txias, txwv qhov chaw ntawm cov chaw khaws hluav taws xob thiab ua rau lub luag haujlwm ntawm kev khaws hluav taws xob tsis muaj zog. Cov roj teeb nickel-hlau hydride hauv qhov kub thiab txias qis heev thiab kub siab zoo heev rau kev them thiab tso tawm, yog li qhov chaw khaws hluav taws xob ntawm qhov chaw yooj ywm dua, yooj yim dua, thiab kev ua tau zoo dua, uas tau dhau los ua nws txoj kev koom tes hauv kev sib tw ntawm ntau txoj kev siv roj teeb "ntxiv cov ntsiab lus".
Qhov tseeb, cov roj teeb nickel-hlau hydride hauv kev lag luam cia khoom siv tau ua ib qho piv txwv. Xyoo 2020, lub tuam txhab cia khoom siv roj teeb nickel-hlau hydride Nilar los ntawm European Investment Bank tau nqis peev 47 lab euros. Nws nkag siab tias Nilar tab tom tsom mus rau kev sib koom ua ke thiab khaws cia hluav taws xob rov ua dua tshiab, lub zog tos thiab cov ntawv thov them hluav taws xob tsheb, kev nqis peev yog los txhawb lub tuam txhab yuav koom ua ke rau hauv lub roj teeb rau cov tsev nyob, kev lag luam thiab kev lag luam thiab cov kab ke lossis cov khoom siv hauv paus. Raws li Frontiers hauv Polymer Science, Xibfwb Yi Cui pab pawg ntawm Stanford University tau tsim lub roj teeb nickel-hlau hydride (Ni-MH) rau kev siv hluav taws xob rov ua dua tshiab thiab kev khaws cia loj, nrog rau qhov zoo ntawm lub neej ntev heev, tsis muaj kev pheej hmoo ntawm hluav taws lossis thermal runaway, tsis tas yuav tsum tau saib xyuas tas li, tus cwj pwm zoo qis-kub, thiab tus nqi qis. Cui pab pawg yuav tsim ib chav tsav dav hlau nrog lub peev xwm cia ntawm 2 megawatts hauv xyoo 2021, thiab npaj yuav nthuav nws lub peev xwm mus rau 20 npaug ntawm qhov nyiaj ntawd los ntawm xyoo 2022.
