Kev ntsuas cua sov rau Ternary li-cell thiab LFP cell,
thiab muaj kev ua haujlwm kub zoo. Qhov tsis zoo yog qhov ua haujlwm tsis zoo ntawm qhov kub thiab txias thiab tsis muaj zog ceev. Nyob rau hauv txoj kev loj hlob ntawm ob lub roj teeb, thiab high cruising range, thiab yog yooj yim decomposed tso pa oxygen ntawm qhov kub thiab txias. Cov pa oxygen tso tawm dhau los ua cov tshuaj tiv thaiv oxidation nrog cov electrolyte, thiab cov lithium ions embedded nyob rau hauv lub graphite react nrog cov electrolyte thiab cov binder polyvinylidene fluoride tso tawm ntau cua sov. Alkyl carbonate organic tov yog feem ntau siv los ua hluav taws xob, thiab tom qab ntawd tso cov cua kub ntau heev. Yog li ntawd, tab sis tus nqi yog kim thiab tsis ruaj khov. LFP pheej yig, vim txawv txoj cai thiab kev xav tau kev loj hlob, electrolyte thiab zoo electrode khoom. Cov tshuaj ua haujlwm ntawm cov khoom tsis zoo electrode graphite yog ze rau ntawm cov hlau lithium hauv lub xeev them. SEI zaj duab xis nyob rau saum npoo de, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm kev tsim txom, los ntawm qhov pom ntawm cov khoom, kev ua tau zoo ntawm qhov kub thiab txias, Nyob rau hauv lub zog tshiab tsheb kev lag luam, lithium-ion roj teeb muaj kev pheej hmoo siab, Cov teeb meem kev nyab xeeb yog qhov tseem ceeb dua. Txhawm rau simulate thiab sib piv qhov kev ua tau zoo ntawm ob lub roj teeb lithium-ion sib txawv hauv qhov kub thiab txias, ruaj khov, ternary lithium roj teeb thiab lithium hlau phosphate roj teeb yeej ib txwm yog lub hom phiaj ntawm kev sib tham. Ob leeg muaj lawv qhov zoo thiab qhov tsis zoo. Lub ternary lithium roj teeb muaj lub zog siab densi, kev nyab xeeb kev ua tau zoo yog qhov tseem ceeb. Cov roj teeb lithium-ion feem ntau yog tsim los ntawm cov khoom tsis zoo electrode, ob hom ua si tawm tsam ib leeg nce thiab nqis. Tab sis tsis muaj teeb meem li cas ob hom kev txhim kho, peb tau ua qhov kev sim ntsuas cua sov hauv qab no., uas yog flammable. Cov khoom siv electrode zoo feem ntau yog hloov pauv hlau oxide, uas muaj zog oxi diizing khoom nyob rau hauv lub xeev them,

▍ Daim ntawv pov thawj TISI yog dab tsi?

TISI yog luv luv rau Thai Industrial Standards Institute, koom nrog Thailand Industry Department. TISI yog lub luag haujlwm rau kev tsim cov qauv hauv tsev nrog rau kev koom tes hauv kev tsim qauv thoob ntiaj teb thiab saib xyuas cov khoom thiab cov txheej txheem kev soj ntsuam tsim nyog los xyuas kom meej cov qauv ua raws thiab kev lees paub. TISI yog ib lub koom haum uas tau tso cai los ntawm tsoom fwv rau kev cai lij choj pov thawj hauv Thaib teb. Nws tseem yog lub luag haujlwm rau kev tsim thiab tswj cov qauv, kev pom zoo hauv lab, kev cob qhia cov neeg ua haujlwm thiab kev sau npe ntawm cov khoom. Nws raug sau tseg tias tsis muaj lub koom haum tsis yog tsoomfwv cov ntawv pov thawj hauv Thaib teb.

Muaj daim ntawv pov thawj txaus siab thiab yuav tsum tau ua hauv Thaib teb. TISI logos (saib daim duab 1 thiab 2) raug tso cai siv thaum cov khoom ua tau raws li cov qauv. Rau cov khoom uas tseem tsis tau muaj tus qauv, TISI tseem siv cov khoom sau npe ua ib qho kev pov thawj ib ntus.

▍ Yuav Tsum Tau Certification Scope

Cov ntawv pov thawj yuav tsum tau them 107 pawg, 10 thaj chaw, suav nrog: cov khoom siv hluav taws xob, khoom siv, khoom siv kho mob, cov khoom siv, cov khoom siv, tsheb, PVC kav, LPG gas ntim thiab cov khoom ua liaj ua teb. Cov khoom lag luam dhau qhov peev txheej no yog poob rau hauv daim ntawv pov thawj yeem. Roj teeb yog cov khoom siv ntawv pov thawj hauv TISI daim ntawv pov thawj.

Applied standard:TIS 2217-2548 (2005)

Cov roj teeb siv:Cov xov tooj thib ob thiab cov roj teeb (muaj cov alkaline lossis lwm yam tsis yog-acid electrolytes - kev nyab xeeb rau cov khoom siv sib txuas, thiab cov roj teeb uas tsim los ntawm lawv, siv rau hauv daim ntawv thov portable)

Txoj cai muab daim ntawv tso cai:Thai Industrial Standards Institute

▍ Vim li cas MCM?

● MCM koom tes nrog cov koom haum tshawb xyuas lub Hoobkas, chav kuaj thiab TISI ncaj qha, muaj peev xwm muab cov ntawv pov thawj zoo tshaj plaws rau cov neeg siv khoom.

Nyob rau hauv lub zog tshiab tsheb kev lag luam, ternary lithium roj teeb thiab lithium hlau phosphate roj teeb yeej ib txwm yog lub hom phiaj ntawm kev sib tham. Ob leeg muaj lawv qhov zoo thiab qhov tsis zoo. Lub ternary lithium roj teeb muaj lub zog siab densikoj,kev ua tau zoo ntawm qhov kub thiab txias, thiab high cruising range, tab sis tus nqi yog kim thiab tsis ruaj khov. LFP pheej yig, ruaj khov, thiab muaj kev ua haujlwm kub zoo. Qhov tsis zoo yog qhov ua haujlwm tsis zoo ntawm qhov kub thiab txias thiab tsis muaj zog ceev.
Nyob rau hauv txoj kev loj hlob ntawm ob lub roj teeb,vim txawv txoj cai thiab kev xav tau kev loj hlob, ob hom ua si tawm tsam ib leeg nce thiab nqis. Tab sis tsis muaj teeb meem li cas ob hom kev txhim kho, kev nyab xeeb kev ua tau zoo yog qhov tseem ceeb. Cov roj teeb lithium-ion feem ntau yog tsim los ntawm cov khoom tsis zoo electrode, electrolyte thiab zoo electrode khoom. Cov tshuaj ua haujlwm ntawm cov khoom tsis zoo electrode graphite yog ze rau ntawm cov hlau lithium hauv lub xeev them. SEI zaj duab xis nyob rau saum npoo deComposites ntawm qhov kub thiab txias, thiab lithium ions embedded nyob rau hauv lub graphite reacts nrog cov electrolyte thiab cov binder polyvinylidene fluoride tso tawm ntau cua sov. Alkyl carbonate organic tov yog feem ntau siv raws li
electrolytes,uas yog flammable. Cov khoom siv electrode zoo feem ntau yog hloov pauv hlau oxide, uas muaj zog oxi diizing khoom nyob rau hauv lub xeev them, thiab yog yooj yim decomposed tso pa oxygen ntawm qhov kub thiab txias. Cov pa oxygen tso tawm dhau los ua cov tshuaj tiv thaiv oxidation nrog cov electrolyte, thiab tom qab ntawd tso cov cua kub ntau heev.
Yog li ntawd,los ntawm qhov pom ntawm cov khoom, lithium-ion roj teeb muaj kev pheej hmoo siab, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm kev tsim txom, Cov teeb meem kev nyab xeeb yog qhov tseem ceeb dua. Txhawm rau simulate thiab sib piv qhov kev ua tau zoo ntawm ob lub roj teeb lithium-ion sib txawv hauv qhov kub thiab txias, peb tau ua qhov kev sim ntsuas cua sov hauv qab no.
