Alise Project: Peb cov lithium-sulfur hlwb tau mus txog 0,325 kWh / kg, peb yuav mus txog 0,5 kWh / kg

Lub Alise Project yog ib txoj haujlwm tshawb fawb los ntawm European Union, koom nrog 16 lub tuam txhab thiab cov koom haum los ntawm 5 lub teb chaws. Cov kws tshawb fawb tsuas khav hais tias lawv tau tsim cov qauv Li-S (lithium-sulfur) cell nrog lub zog ceev ntawm 0,325 kWh / kg. Qhov zoo tshaj plaws lithium-ion hlwb tam sim no siv tau txog li 0,3 kWh / kg.

Cov txheej txheem

Ntau qhov ceev = ntau dua cov roj teeb them ntau dua
- Li-S hauv tsheb: pheej yig dua, sai dua, ntxiv. Tab sis tsis yog tam sim no

Lub cell lub zog ntau dua txhais tau tias nws tuaj yeem khaws ntau lub zog. Ntau lub zog rau ib chav tsev loj yog ib qho ntau ntau ntawm cov tsheb hluav taws xob (thaum tuav lub roj teeb tam sim no), lossis lwm yam tam sim no muaj ntau yam nrog cov roj teeb me me thiab sib dua... Txawm txoj kev twg los xij, qhov xwm txheej yeej ib txwm yeej rau peb.

Lithium-sulfur ntsiab yog ib qho tseem ceeb heev tshawb fawb khoom thaum nws los txog rau lub zog ceev ntawm ib chav tsev loj ntawm cov ntsiab lus. Lithium thiab sulfur yog lub teeb, yog li lub caij nws tus kheej tsis hnyav. Txoj haujlwm Alise tau ua tiav 0,325 kWh / kg, uas yog kwv yees li 11 feem pua ntau tshaj li Tuam Tshoj tus CATL thov hauv nws cov lithium-ion tam sim no:

Ib qho ntawm cov koom nrog Alise Project, Oxis Energy, yav dhau los tau cog lus tias qhov ceev ntawm 0,425 kWh / kg, tab sis nyob rau hauv EU project, cov kws tshawb fawb tau txiav txim siab txo qhov ntom ntom rau, ntawm lwm yam, ua tiav: kev them nyiaj ntau dua. Txawm li cas los xij, thaum kawg lawv xav hloov mus rau 0,5 kWh / kg (ib qhov chaw).

Lub roj teeb yog raws li cov modules uas muaj Li-S (c) Alise Project cells.

Li-S hauv tsheb: pheej yig dua, sai dua, ntxiv. Tab sis tsis yog tam sim no

Lithium thiab sulfur-based hlwb zoo li pheej hmoo, tab sis kev txaus siab tau ploj mus rau tam sim no. Lawv ceeb toom koj tias tseem muaj txoj hauv kev mus ntev. Piv txwv li Li-S roj teeb tam sim no tiv taus txog 100 lub sij hawm them-tso tawm.thaum 800-1 cycles raug suav hais tias yog qhov tsim nyog yam tsawg kawg nkaus hnub no, thiab twb muaj cov qauv kev cog lus 000-3 lub voj voog them nyiaj:

Kub kuj yog ib qho teeb meem: Tshaj li 40 degrees Celsius, Li-S hlwb decompose sai... Cov kws tshawb fawb xav tsa qhov pib no kom tsawg kawg 70 degrees, qhov kub uas tshwm sim nrog kev them nyiaj ceev heev.

Txawm li cas los xij, muaj ib yam dab tsi los tawm tsam, vim tias hom cell no tsis tas yuav kim, nyuaj nrhiav cobalt, tab sis pheej yig lithium thiab yooj yim muaj leej faj. Ntxiv mus, lub theoretical zog ceev nyob rau hauv sulfur yog mus txog 2,6 kWh / kg - yuav luag kaum npaug tshaj li qhov zoo tshaj plaws lithium-ion hlwb qhia hnub no.
