Yuav ua li cas paub qhov zoo thiab qhov tsis zoo ntawm cov roj teeb



1. Kev faib tawm los ntawm cov roj teeb ua tau zoo


 


Cov roj teeb muaj zog thiab cov roj teeb muaj zog. Lub zog hluav taws xob hom roj teeb yog cov yam ntxwv ntawm lub zog siab ceev thiab feem ntau yog siv rau cov khoom siv hluav taws xob siab; Lub hwj chim hom roj teeb yog tus yam ntxwv los ntawm lub zog ceev ceev thiab yog siv rau instantaneous siab zog tso zis thiab tso zis roj teeb. Lub zog fais fab lithium roj teeb yog nrog los ntawm qhov tshwm sim ntawm ntsaws- hauv tsheb hybrid. Nws yuav tsum muaj lub zog cia siab hauv lub roj teeb, uas tuaj yeem txhawb nqa hluav taws xob ntshiab rau kev ncua deb, thiab tseem muaj cov yam ntxwv ntawm lub zog zoo thiab nkag mus rau hom hybrid thaum lub roj teeb qis.


 


A simple understanding is that the energy type is similar to a marathon runner. To have endurance, it requires high capacity and does not require high current discharge performance; then the power type is a sprinter, who fights for explosive power, but also has endurance, otherwise the capacity is too high. I can't run far.


 


2. Raws li cov khoom siv electrolyte


 


Cov roj teeb lithium-ion roj teeb tau muab faib ua kua lithium-ion roj teeb (LIB) thiab polymer lithium-ion roj teeb (PLB).


 


Liquid lithium-ion batteries use liquid electrolytes (most of which are currently used in power batteries). The polymer lithium-ion battery is replaced by a solid polymer electrolyte. This polymer can be "dry" or "colloidal". At present, most of the polymer gel electrolytes are used. With respect to solid-state batteries, it is strictly meant that both the electrodes and the electrolyte are solid-state.


 


3. Kev faib tawm los ntawm cov khoom muag


 


Muab faib ua: cylindrical, mos pob, square.


 


Lub cylindrical thiab square txheej ntim yog feem ntau steel plhaub los yog txhuas plhaub. Lub ntim sab nrauv ntawm lub pob mos yog aluminium- zaj duab xis yas. Qhov tseeb, cov mos - pob kuj yog ib qho square. Hauv kev ua lag luam, aluminium- zaj duab xis yas yog siv los hu ua mos- pob, thiab qee cov neeg hu ua mos- pob roj teeb polymer.


 


Rau cylindrical lithium{0}} ion roj teeb, tus qauv naj npawb feem ntau yog 5 tus lej. Thawj ob tus lej yog lub cheeb ntawm lub roj teeb, thiab qhov nruab nrab ob tus lej yog qhov siab ntawm lub roj teeb. Unit yog mm. Piv txwv li, 18650 lithium roj teeb muaj txoj kab uas hla ntawm 18 hli thiab qhov siab ntawm 65 hli.


 


4. Kev faib tawm los ntawm cov khoom siv ncej


 


Cov khoom siv hluav taws xob zoo: lithium hlau phosphate roj teeb (LFP), lithium cobalt oxide roj teeb (LCO), lithium manganate roj teeb (LMO), (cov roj teeb binary: lithium nickel manganese oxide / lithium nickel cobalt oxide), (ternary: nickel cobalt manganese oxide) Lithium Oxide Battery (NCM), Nickel Cobalt Aluminate Battery (NCA)).


 


Cov khoom siv anode: lithium titanate roj teeb (LTO), graphene roj teeb, nano carbon fiber roj teeb.


 


Hais txog lub tswv yim ntawm graphene ntawm kev ua lag luam, nws feem ntau yog hais txog graphene - raws li cov roj teeb, uas yog, ntxiv graphene slurry rau cov ncej, los yog ntxiv graphene txheej rau lub separator. Lithium nickelate thiab magnesium- cov roj teeb raws li qhov pib tsis muaj nyob hauv khw.
