Qhov txiaj ntsig zoo no yog los ntawm kev tswj hwm thermal zoo dua thiab kev tiv thaiv kev tiv thaiv kev tiv thaiv sab hauv kev puas tsuaj. Txawm li cas los xij, tsim nyog thermal thiab mechanical tsim tuaj yeem nqa lub hnab cell lifespan li ntawm 10-15% ntawm prismatic sib npaug. Lub neej tiag tiag nyob ntawm kev ua haujlwm ntau dua (kub, them raws tu qauv, tso tawm qhov tob) dua li hom ntawv ib leeg.

Kev ruaj ntseg profiles sib txawv ntau dua li qeb duas hierarchically. Cov hlwb prismatic muaj qhov ua tsis tiav nyob rau hauv cov vaj tse tsis zoo tab sis ua kom muaj kev ntxhov siab ntau dua thaum lub sij hawm thermal tshwm sim - muaj peev xwm ua rau muaj kev kub ntxhov. Lub hnab ntim tsis tau maj mam maj mam los ntawm qhov o, muab cov lus ceeb toom pom, tab sis lawv cov ntim ntim tau yooj yim tsis muaj kev tiv thaiv qhov tseem ceeb. Cov txheej txheem tsim kho kom zoo ua tiav kev nyab xeeb zoo sib xws tsis hais hom twg los ntawm kev tswj xyuas thermal tsim nyog, kev tsim kho tshuab, thiab kev tiv thaiv roj teeb.

Daim ntawv thov tseem ceeb tsav xaiv hom ntawv. Smartphones optimize qhov tsawg kawg nkaus thickness thiab hnyav nyob rau hauv benign mechanical ib puag ncig-pob cell excel hauv cov qauv no. Cov tsheb hluav taws xob ua ntej lub neej voj voog, kev ruaj ntseg thermal, thiab kev siv tshuab ua haujlwm ntev tshaj li qhov kev txuag nyiaj ntau dua - prismatic hlwb zoo dua rau cov kev xav tau no. Txawm li cas los xij, muaj kev zam: qee qhov EVs (qee yam Nissan Leaf variants) tau ua tiav cov hnab ntim khoom, thaum lub xov tooj rugged tuaj yeem qhia cov hlwb me me rau kev txhim kho kom ruaj khov.

Kev xaiv hom cuam tshuam rau 15-30% ntawm tag nrho cov roj teeb hluav taws xob raug nqi tshaj li cov nqi ntawm tes. Prismatic hlwb raug nqi 15-20% ntau dua ib kilowatt-teev tab sis xav tau cov qauv kev txhawb nqa yooj yim dua. Lub hnab ntim txuag ntawm cov nqi ntawm tes tab sis xav tau cov tshuab compression thiab kev tswj xyuas thermal. Nyob rau theem system, tus nqi sib txawv nqaim mus rau 5-15% nyob ntawm qhov ntim ntau lawm thiab cov khoom siv thermal. Kev ua tau zoo thiab kev ntseeg siab feem ntau cuam tshuam cov nqi ncaj qha rau hauv kev xaiv hom.

Prismatic thiab lub hnab ntim khoom sawv cev rau kev ntim khoom sib txawvrau lithium-ion chemistry-cov plaub hau tsis zoo tiv thaiv cov laminates yooj yim-txhua qhov kev ua kom zoo sib txawv ntawm kev ua haujlwm tsis yog sawv cev rau cov thev naus laus zis zoo tshaj / qis dua

Lub zog ntom ntom nyiam lub hnab tsim(174 Wh / kg) dhau prismatic lwm txoj kev (157-165 Wh / kg), txhais ua 10-15% qhov hnyav txuag tseem ceeb rau cov khoom siv hluav taws xob portable thiab kev siv aerospace

Qhov zoo ntawm kev tswj cua sov yog rau cov qauv prismaticlos ntawm cov hlau plhaub thaum tshav kub kub dissipation, ua kom muaj kev ruaj ntseg siab - lub zog tso tawm hauv tsheb thiab kev lag luam kev lag luam uas lub hnab ntim xav tau cov txheej txheem txias txias

Cov qauv nqi sib txawv ntawm cov tswv yim: hnab ntim khoom xa tuaj 15-20% tus nqi tsim khoom qis dua tab sis xav tau ntau dua qhov system- theem kev nqis peev hauv kev txhawb nqa tshuab thiab kev tswj xyuas thermal-tag nrho cov nqi sib txuas hauv 5-15% ntawm qhov ntsuas

Cov kev xav tau ntawm daim ntawv thov tsav qhov kev xaiv zoo tshaj plawsthoob plaws rau qhov kev txiav txim siab qhov ntev: lub zog profile, ib puag ncig txhua yam, qhov chaw txwv, ntim ntau lawm, kev xav tau ntawm lub neej, thiab kev tswj hwm kev nyab xeeb -tsis muaj hom "zoo tshaj" thoob plaws hauv kev siv
