LiPo vs Li-ion zog ceev: Wh/kg vs Wh/L Piav

Cylindrical Li-ion roj teebfeem ntau ua tiav siab duacell-level zog ceev, thaumLiPo hnab roj teebtuaj yeem xa qhov chaw siv tau zoo dua hauv cov khoom siv nyias nyias lossis kev cai zoo li.

Rau OEM cov khoom siv roj teeb, sib piv peb qhov ntsuas:

• Wh/kg (gravimetric zog ceev):Zog khaws cia ib kilogram ntawm roj teeb loj.
• Volumetric zog ceev (Wh/L):Lub zog khaws cia ib liter ntawm roj teeb ntim.
• Installed zog ceev:Lub zog khaws cia nyob rau hauv lub roj teeb tag nrho qhov hnyav thiab qhov ntev.

Cov lus nug tseem ceeb ntawm kev yuav khoom:Lub roj teeb twg siv tau ntau dua watt-teev hauv koj cov khoom hnyav, qhov chaw, thiab kev txwv kev ua haujlwm?

Rau qhov sib txawv ntawm kev them nqi, kev nyab xeeb, thiab kev ua neej nyob, saibBlumoti's Li Polymer Battery vs Lithium Ion Battery guide

1. Wh/kg vs Wh/L: Qhov Metric Yuav Tsum Roj Teeb Cov Neeg Yuav Sib Piv?

Gravimetric zog density (Wh/kg) ntsuas lub zog ntawm lub roj teeb txheeb ze:
Wh/kg=Nominal Zog (Wh) ÷ Roj teeb Mass (kg)

Volumetric zog density (Wh/L) ntsuas cia lub zog txheeb ze rau ntim ntim:
Wh/L=Nominal Zog (Wh) ÷ Roj teeb Volume (L)

Nominal zog yog kwv yees li Voltage (V) × Capacity (Ah). [1]
Xav txog ob lub tswv yim 3.7V, 3,000 mAh lithium roj teeb hlwb, txhua qhov khaws cia 11.1 Wh:

Cell A muab kwv yees li 10% ntau zog ib kilogram. Cell B khaws tib lub zog hauv kwv yees li 18% tsawg dua ntim.

Rau qhov hnyav-rhiab heevUAV Battery, Cell A tej zaum yuav ntxim nyiam dua. Rau cov cuab yeej kho mob nyias, Cell B yuav haum zoo dua.

Kev kuaj xyuas khoom:Paub meej tias txhua tus neeg muag khoom tus lej Wh/kg thiab Wh/L piav qhia txog lub xov tooj liab qab, tiv thaiv lub xov tooj, lossis cov roj teeb ua tiav. Sib piv cov ciam teb sib txawv ua rau cov txiaj ntsig tsis raug.

2. Vim li cas LiPo thiab Li-ion Energy Density Figures txawv?

Qhov txawv los ntawmelectrode chemistry, cell tsim, thiab ntim-tsis yog LiPo lossis Li-ion daim ntawv lo.

Ob lub thev naus laus zis muaj nyob rau tsev neeg lithium-ion rechargeable. Kev lag luamLiPo roj teebfeem ntau siv laminated hnab ntim, thaum18650 thiab 21700 Li-ion roj teebsiv nruj cylindrical casings.

► Cov khoom siv hluav taws xob cuam tshuam li cas Wh/kg thiab Wh/L?

Cathode cov ntaub ntawv xws liNMC, NCA, and LCO, nrog rau electrode loading, thickness, thiab inactive khoom cov ntsiab lus, txiav txim siab npaum li cas lub zog ntawm lub cell yuav khaws cia.

High-zog formulations xws liSIB 811tuaj yeem txhawb zog siab dua, tab sis electrode tsim thiab kev khiav hauj lwm yuav tsum tau cuam tshuam rau qhov kawg tshwm sim.

 

► Cell ntim yuav cuam tshuam li cas rau lub zog ntom ntom?

Ib lub cylindrical cell muaj ib qho tawv hlau casing. ALiPo hnab cellsiv lub teeb aluminium-laminated ntim tab sis tej zaum yuav xav tau kev txhawb nqa khoom siv ntxiv thiab kev tshem tawm o. [3][5]

A kev cai LiPo roj teebtuaj yeem tuav tau ntau dua ntawm cov ntaub thaiv nyias dua li lub pob cylindrical. Qhov ntawd txhim kho qhov chaw siv, tab sis tsis cia li txhais tau tias lub hnab ntawm tes muaj ntau dua intrinsic Wh / L.

Kev kuaj xyuas khoom:Sib piv qhov tseeb ntawm tes chemistry, nominal zog, sab nraud qhov ntev, thiab tiav pob configuration-tsis yog roj teeb hom ib leeg.

3. Cell-Level vs Pob-Level Zog Ceev: Tus lej twg cuam tshuam koj cov khoom?

Tus neeg muag khoom quotes a600 Wh/L lithium-ion cell. Puas yog qhov ntawd txhais tau tias koj cov roj teeb ua tiav xa 600 Wh / L?

Tsis muaj.

Qhov sib txawv ntawm tes, thaiv, rwb thaiv tsev, tiv thaiv Circuit Court, thiab cov khoom siv hauv txhua qhov chaw nyob. Tib yam siv rau pob qhov hnyav.

Rau lub roj teeb ua tiav:

• Nruab Wh/L=Tag Nrho Nominal Pob Zog (Wh) ÷ Ua tiav Roj Teeb-System Volume (L)
• Nruab Wh/kg=Tag Nrho Nominal Pob Zog (Wh) ÷ Ua tiav Roj Teeb-System Mass (kg)

► Piv txwv ua haujlwm: Puas tuaj yeem txo qis Cell Wh/L xa ntau zog hauv tib qhov chaw?

Xav tias ib yam khoom muaj ib0.10L roj teeb compartment.

Ob txoj kev tsim qauv siv lub zog sib txawv ntawm cov xov tooj ntawm tes thiab cov khoom ntim.

Tsim Y haum rau kwv yees li 4.6% ntau lub zog nominal, txawm tias nws cov cell-theem Wh / L yog 20% ​​qis dua.

Kev suav yooj yim yog:

• Nruab Lub Zog (Wh) ≈ Cell Wh/L × Qhov ntim ntim (L) × Cov khoom ntim zoo

Cov no yog cov piv txwv piv txwv, tsis kuaj cov khoom muaj txiaj ntsig lossis cov qauv kev ntim khoom-kev ua tau zoo. Qhov tshwm sim tiag tiag nyob ntawm qhov ua tiav cov tshuab thiab hluav taws xob tsim.

Qhov no yog vim li cascell-level zog ceevib leeg tsis tuaj yeem txiav txim siab lub roj teeb zoo tshaj plaws rau cov khoom siv hauv qhov chaw txwv.

Kev kuaj xyuas khoom:Thov kom tiav pob kos duab, qhov siab tshaj plaws sib sau ua ke, ua tiav qhov hnyav, thiab tag nrho nominal Wh. Muab xam nruab Wh/L thiab Wh/kg los ntawm cov duab ntawd.

4. LiPo vs Li-ion Energy Density Values ​​Yuav Tsum Tau Txais Kev Ntseeg?

Blumoti niam txiv phau ntawv qhia muab davgravimetric zog ceevntau yam ntawm kwv yees li:

• Cov Lus Qhia Li-ion:150-250 Wh/kg
• Lithium polymer (LiPo):100-265 Wh/kg

Cov kab no sib tshooj thiab sib txawv nrog cell chemistry thiab tsim.

Lwm cov kev sib piv kev sib piv yuav hais200–270 Wh/kg thiab 550–700+ Wh/Lrau xaiv cylindrical Li-ion hlwb, piv rau140-220 Wh / kg thiab 300-500 Wh / Lrau tshwj xeeb LiPo hnab tsim. Xws li cov nuj nqis yuav tsum tsis txhob raug kho raws li cov lus qhia thoob ntiaj teb lossis cov txiaj ntsig sib piv ncaj qha.

► Yuav Ua Li Cas Cov Neeg Yuav Tshawb Xyuas Tus Neeg Siv Khoom Wh/kg lossis Wh/L thov?

Ib tug hais250 Wh/kglos yog700 W/Ltsuas yog siv tau thaum ntsuas cov xwm txheej pom tseeb.

Ua ntej lees txais qhov tshwj xeeb, xyuas:

• Nominal zog:Rated peev (Ah) thiab nominal voltage (V).
• Kev ntsuas ciam teb:Ntshiab cell, tiv thaiv cell, los yog tiav pob.
• Cov ntaub ntawv lub cev:Ntsuas qhov loj thiab qhov siab tshaj plaws sab nraud.
• Cov xwm txheej xeem:Tshem tawm tam sim no, kub, thiab txiav tawm voltage.
• Production kam rau ua:Tus nqi piv rau guaranteed yam tsawg kawg nkaus.

Piv txwv li, tus neeg muag khoom thov 250 Wh / kg rau 11.1 Wh ntawm tes yuav tsum muab lub xov tooj ntawm tes ntawm kwv yees li 44.4 g, piv txwv li cov txiaj ntsig tau hais qhia tib qhov kev ntsuas ciam teb.

Kev kuaj xyuas khoom:Rov xam cov lus hais Wh/kg thiab Wh/L. Rau kev pom zoo ntau lawm, siv qhov kev pom zoo yam tsawg kawg nkaus thiab cov ntawv pov thawj lees paub tsis yog cov ntaub ntawv lag luam.

 

5. Puas muaj zog ceev dua txhais tau tias lub roj teeb ntev dua?

Tsis tas li.

Nominal Wh/kgntsuas lub zog khaws cia raws li kev ntsuas ntsuas. Lub sijhawm ua haujlwm tiag tiag nyob ntawm seb lub zog npaum li cas lub roj teeb xa tawm ntawm qhov xav tau.

 

Internal kuj,zog sag, kev khiav hauj lwm kub, thiab txiav tawm voltage tuaj yeem txo lub zog siv tau.

 

Piv txwv li, lub zog cylindrical Li-ion ntawm tes yuav ua tau zoo dua lub hnab ntawm tes ntawm qhov paug tawm, thaum lubLiPo roj teeb muaj peev xwmtuaj yeem tswj tau qhov hluav taws xob siv tau ntau dua raws li qhov xav tau tam sim no hnyav. Cov txiaj ntsig yog nyob ntawm cov hlwb tshwj xeeb, tsis yog lawv cov ntim ib leeg.

 

Raulong-range UAV batteries, robotics, thiab lwm yam high-drain khoom, sib piv:

• Lub zog xa tawm (Wh)ntawm qhov kev khiav hauj lwm tam sim no.
• Nruam thiab siab tshaj tawm muaj peev xwm (C-rate / A).
• DC sab hauv tsis kam (mΩ)thiab voltage sag.
• Kub nce thiab qhov tsawg kawg nkaus ua haujlwm voltage.

Kev kuaj xyuas khoom:Nug cov neeg muag khoom rau kev tawm nkhaus thiab ntsuas xa Wh ntawm koj qhov tseeb. Siab dua nominal zog ceev tsis lav lub sij hawm ua hauj lwm ntev dua.

6. Cov neeg yuav khoom yuav tsum suav nrog li cas hauv LiPo vs Li-ion Energy Density RFQ?

Kev thov rau ib3.7V, 3,000 mAh roj teebtsis muab cov ntaub ntawv txaus los sib piv cov zog ceev.

Thov cov tswv yim sib piv uas siv tib lub sijhawm.

Ib daim ntawv teev cov khoom siv tau zoo yuav tsum qhia ob qho tib sicell-level Wh/kg/Wh/Lthiabtiav pob-theem Wh/kg/Wh/L, qhov twg siv tau.

Rau cov haujlwm OEM, qhov no tiv thaiv kev ua haujlwm siab ntawm tes los ntawm kev npog lub roj teeb tsis zoo tsim.
