Rau ib lub sijhawm ntev, tsawg (hauv qab- 20℃thiab txawm tias muaj zog tsis muaj zog " Ntiaj teb no, los ntawm kev txhim kho cov khoom, thiab kev tswj hwm ntawm cov roj ntsha tsis tau muaj ntau dua li 80%
1 cov khoom siv theem: txhim kho qis {{1} ion conductivity efficiency
Tuam Tshoj tus "qis - kub hloov kho electrolyte". Tus "Composite Ejher electrolyte" tsim los ntawm qee qhov kev lag luam yog kev sib xyaw ntawm cov khoom siv dag zog ntawm 3: 7, ua ke nrog cov khoom siv dag zog ntawm 3: 7} ion 40 degree, nrog ion conductivity ntawm 1.2ms / cm, uas yog tsib zaug siab dua cov roj carbonate electrolytes. Ib txhij ntxiv 5% adiponitrile raws li qhov tsawg-kub yas ua kom tsawg dua ntawm 85% rau lub roj teeb kom tsawg dua ntawm ntawm -30 degree, uas yog 35% siab dua ntawm cov roj teeb tsis muaj teeb meem. Cov thev naus laus zis no tau siv rau lub zog hluav taws xob tshiab nyob rau hauv Northeast Suav, nrog 20% nce ntxiv nyob rau lub caij ntuj no ntau.
Nordic 'zoo electrode nanomsiably thiab tsis zoo electrode pre litiation'. Norwegian cov tuam ntxhab tau tsoo cov iron piv txwv rau 50nm (kev coj ua ib txwm muaj 100,00nm), ua kom muaj txoj cai nyob rau sab nraud; Qhov tsis zoo electrode siv "lithiated graphite" (ua ntej lithiation℃ntawm 5%) kom them nyiaj rau cov kev ntsuas lithaium poob ntawm cov kub qis. Lub roj teeb optimized tau them nyiaj ua haujlwm ntawm 70% tsuas yog muaj 305℃(thiab lub peev xwm khaws cia. Nyob rau hauv lub zog cia tes hauj lwm ntawm Arctic scartic chaw nres tsheb chaw nres tsheb, kev daws teeb meem ntawm cov roj teeb kev tshawb fawb ib txwm muaj '"tsawg kub dollapse".
2 tus qauv tsim qauv: txhim kho qis - kub hloov tau
Qhov "huab li thinning thiab ntau - txheej teeb" hauv Tebchaws Asmeskas. Tesla lub Lithium Iron phosium phosphate roj teeb rau lub " Nyob rau tib lub sijhawm, "ntau {{{}} txheej teeb cov txheej txheem" (150 txheej electrodes stacked) thiab txo qhov ntom ntom. Cov qauv no tso cai rau lub roj teeb ntawm kev them nqi ntawm 0.5c txawm tias ntawm -30 degree, uas yog qhov loj me ntsis roj teeb hlwb. Hauv kev ntsuam xyuas hauv Alaska, cov tsheb hluav taws xob tau hloov nrog lub roj teeb roj teeb no tuaj yeem rov qab 80% ntawm lawv lub peev xwm tom qab -25 degree, sib ntsib txhua hnub xav tau kev xav tau txhua hnub.
Tuam Tshoj tus "hloov pauv ncej pob ntseg thiab cov qauv sib tham". Tsim "hloov tau hluav taws xob hluav taws xob Lithium phosphate roj teeb Lub plhaub sab nraud ntawm cov tub ntxhais yog qhwv nrog 1 hli tuab {ruam (thermal 5W), thiab muaj peev xwm khaws cia hauv PTGE (ME ceev. Hauv cov phiaj xwm tawm ntawm daim phiaj photovoltaic hauv yushai, qhov nruab nrab txhua hnub muab cov hluav taws xob xav tau ntawm cov tsev neeg.
3 Qhov Kub Tswj Kev Pab: Scenario raws li qhov ntsuas kub tsawg
Lub synergy ntawm cov khib nyiab kub rov qab thiab cov cua sov nquag hauv tebchaws Russia. Cov kev sib txuas lus hauv chaw nres tsheb chaw nres tsheb hluav taws xob cia khoom hauv cov duab cua kub (CPU Thaum lub ambient kub yog qis dua -30 degree, muaj feem thib tau muab los siv cov cua sov. Yog tias nws tsis txaus, cov yeeb yaj kiab cua sov tau ua haujlwm kom ruaj khov rau qhov kub thiab txias sab hauv lub tsev ntawm 10-15 degree. Lub roj teeb muaj peev xwm khaws cia tus nqi yuav ncav cuag 95%, uas yog 60% ntau lub zog-npaum li cas tshaj li cov cua kub ua haujlwm ntshiab. Qhov kev daws teeb meem no nce lub zog muaj peev xwm ntawm cov chaw nres tsheb hauv 30% nyob rau lub caij ntuj no, zam kev cuam tshuam kev sib txuas lus los ntawm qhov chaw kub.
Theem Hloov Khoom Hloov thiab Hnub Ci Preheating hauv Canada. Rau cov phiaj xwm tawm ntawm thaj chaw deb, cov chaw nres tsheb theem (melting taw tes 8 degree) tau sau nyob ib ncig ntawm cov roj teeb lithium phosphate roj teeb. Thaum nruab hnub, theem hloov pauv tau rhuab (khaws cia) los ntawm cov hnub ci hloov, thiab thaum tsaus ntuj, theem hloov pauv hloov cua sov kom lub hlwb insulated kub; Nyob rau tib lub sijhawm, nruab cov phaj txhim kho sab nraud ntawm lub roj teeb module los pab hauv preheating lub teeb roj teeb lub caij ntuj no. Nyob rau hauv daim phiaj cabin project nyob rau hauv Ontario, cov tshuaj no ua rau muaj roj teeb rau hauv 80% thiab cov hluav taws xob txuag tau txhua xyoo ntawm 1200 kWh.
Qhov kev sib tawg hauv qis -} Cov hlau kub ntawm cov roj teeb lithium yog tsis haum rau cov iron Iron phosphate '. Nyob rau yav tom ntej, nrog rau daim ntawv thov ntawm cov khoom siv electrolytes (nrog rau cov qauv ntawm kev ua haujlwm ntawm Lithium. Thiab kev xaiv txhim khu kev qha rau kev hloov pauv ntawm lub zog tshiab hauv cov cheeb tsam txias thiab qhov chaw siab tshaj plaws thoob ntiaj teb.
