Puas yog lub roj teeb polymer lithium-ion thiab peb-dimensional lithium ion roj teeb tawg? Lub roj teeb lithium-ion zoo heev txhim kho qhov teeb meem ntawm ntau yam khoom siv digital nws tus kheej, tau dhau los ua ib feem tseem ceeb ntawm tib neeg. Txawm li cas los xij, nyob rau xyoo tas los no, peb feem ntau pom qee qhov xwm txheej kev nyab xeeb tshwm sim los ntawm lithium-ion roj teeb. Nws yog qhov zoo tshaj plaws rau kev tawg ntawm lithium-ion roj teeb, thiab hluav taws kub, thiab lwm yam.
Cov koob me me hauv qab no yuav siv los ua piv txwv ntawm cov roj teeb polymer lithium-ion thiab peb-dimensional lithium ion roj teeb, thiab lithium-ion roj teeb yuav tawg. Lub roj teeb tawg yog dab tsi? Lub teb chaws tus txheej txheem teev tseg tias cov teeb meem hauv lub roj teeb tau tawm tam sim ntawd, thiab qhov kev ncua deb ntawm lithium ion roj teeb yog hu ua qhov tawg. Kev ntsuas nyob rau hauv qhov kev ntsuam xyuas yog los npog ib ncig mesh nyob rau hauv lub roj teeb kuaj, uas yog nyob rau hauv lub center txoj hauj lwm, i.
e., qhov kev ncua deb ntawm lub net npog yog 25cm, yog tias qhov kev sim tsis muaj cov khoom seem dhau los ntawm lub hau npog, qhia tias lub roj teeb tsis tawg. Puas yog lub roj teeb polymer lithium ion tawg? Lub roj teeb polymer lithium ion muaj qhov hnyav me me, nyias nyias.
Siv ntau thiab ntau zaus, txawm hais tias hloov lwm hom roj teeb tseem tab tom ua, nyob rau hauv hom lithium ion roj teeb, polymer lithium ion roj teeb tau pib hloov cov roj teeb lithium ion hauv qee pawg. Hais txog cov qauv, cov roj teeb polymer lithium-ion siv aluminium-yas mos ntim, uas txawv ntawm cov hlau casing ntawm cov kua hluav taws xob ntawm tes. Thaum muaj kev nyab xeeb tshwm sim, cov kua hluav taws xob ntawm tes tau yooj yim tawg, thiab cov roj teeb polymer tsuas yog lub nruas.
Tsuav nws tsis yog tib neeg kev puas tsuaj, lub polymer lithium ion roj teeb tseem muaj kev nyab xeeb. Txawm hais tias nws muaj kev ruaj ntseg dua, cov roj teeb polymer lithium-ion yog ib qho yooj yim rau nruas, ib zaug lub nruas, seb qhov zoo li qub, lub roj teeb tau muab pov tseg. Puas yog ternary lithium-ion roj teeb tawg? Qhov ntsuas kub tsis zoo ntawm ternary lithium ion roj teeb yog qhov zoo heev, thiab kev them nyiaj tuaj yeem them ntawm -20 º C.
Txawm li cas los xij, qhov ua tau zoo ntawm qhov kub thiab txias yog qhov tsis zoo, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias, peb-dimensional ion roj teeb yog qhov txaus ntshai heev, luv luv Circuit Court muaj hluav taws kub, muaj peev xwm tawg. Tau kawg, feem ntau ntawm cov roj teeb lithium-ion muaj kev tiv thaiv luv luv tiv thaiv Circuit Court, nrog rau kev tawg-pov thawj, tab sis nyob rau hauv ntau qhov xwm txheej, qhov kev tiv thaiv Circuit Court no tsis tas yuav ua haujlwm rau ntau qhov xwm txheej, thiab kev siv cov kab tawg tuaj yeem raug txwv. Summary : Ntau yam yog qhov sib npaug ntawm kev nyab xeeb thiab kev ua tau zoo.
Piv txwv li, kev sib tsoo tsheb yuav muaj ntau yam kev sib tsoo txhua xyoo. Kev tuag ntawm cov neeg tuag nyob rau hauv ib lub tsheb sib tsoo suav rau ib feem ntawm lub tebchaws yog qhov txawv txav, thiab muaj hluav taws xob ua rau feem ntau ntawm cov hluav taws kub. Tib lub xov tooj ntawm tes lithium hluav taws xob yog ob peb billion daim, muaj ntau qhov tawg.
Peb tsis siv koj lub xov tooj ntawm tes? Tsis txhob tsav tsheb tsis muaj hluav taws xob? Lub ntiaj teb no tsis muaj kev ruaj ntseg kiag li, kev ruaj ntseg nrog kev ua tau zoo, qhov peb yuav tsum ua yog txo qis kev phom sij. Kev tiv thaiv kev tiv thaiv kev tiv thaiv ntawm cov roj teeb polymer lithium ion: Thaum lub roj teeb polymer lithium ion raug them, nws yuav tsum teeb tsa lub siab tshaj plaws ntawm kev them hluav taws xob, qhov hluav taws xob tawm hluav taws xob, thiab qhov txwv siab tshaj ntawm tam sim no. Qhov no tso cai rau ob qho tib si lub neej, muaj peev xwm, thiab kev ruaj ntseg ntawm lub roj teeb.
Ua tib zoo saib xyuas luv luv: Polymer lithium ion roj teeb tau yooj yim luv luv thaum them nyiaj. Xws li: internal short circuit, sab nraud luv luv Circuit Court, thiab lwm yam. Nco ntsoov xyuam xim rau cov xwm txheej no, tiv thaiv kev sib tsoo los ntawm hluav taws kub lossis tawg.
Kev tiv thaiv kev nyab xeeb them ib puag ncig ntawm peb-yuan lithium-ion roj teeb: peb yuan lithium-ion roj teeb yuav tsum nyob rau hauv qhuav thiab txias, tiv thaiv raug. deb ntawm nplaim taws. Yuav siv li cas: Trimmonic ion roj teeb yuav tsum xyuam xim rau qhov kub thiab txias, tsis txhob siv ternary lithium ion roj teeb nyob rau hauv ib puag ncig kub.
Cov roj teeb polymer lithium-ion thiab peb-yuan lithium ion roj teeb muaj qhov zoo thiab qhov tsis zoo, thiab cov tuam txhab roj teeb yuav tsum tau them nyiaj ntau rau kev nyab xeeb ntawm lub roj teeb, txhim kho kev soj ntsuam xyuas, nruj lav zoo kom ntseeg tau tias kev siv roj teeb lithium-ion. Cov saum toj no yog hais tias lub polymer lithium-ion roj teeb thiab peb-dimensional ion roj teeb yog thawj decomposition ntawm tawg. Tom qab nyeem koj cov roj teeb polymer lithium-ion thiab peb-yuan lithium ion roj teeb, txais tos hu rau peb, kev pabcuam hauv online rau koj teb.
