Peb tau tsim cov phaj graphite bipolar uas pheej yig thiab yuav tsum tau siv cov phaj bipolar uas muaj hluav taws xob zoo thiab muaj zog zoo. Nws tau ua kom zoo los ntawm kev tsim siab, kev nqus tsev, thiab kev kho cua sov kub. Peb cov phaj bipolar muaj cov yam ntxwv ntawm kev tiv taus kev hnav, kev tiv taus kub, kev tiv taus siab, kev tiv taus xeb, kev tiv taus nkag, kev tsis muaj roj, kev nthuav dav me me, thiab kev ua haujlwm zoo heev.
Peb tuaj yeem siv tshuab ua cov phaj bipolar rau ob sab nrog cov teb ntws, lossis siv tshuab ib sab lossis muab cov phaj dawb uas tsis tau siv tshuab. Txhua daim phaj graphite tuaj yeem siv tshuab raws li koj tus qauv tsim.

Cov txiaj ntsig tseem ceeb ntawm peb lub phaj bipolar:
1. Kev ua hluav taws xob siab heev, pab hloov pauv hluav taws xob zoo
High-purity graphite ≥99.9%, conductivity txog li 150 S / cm, kom ntseeg tau tias xoom poob hauv kev sib kis tam sim no.
Kev tiv thaiv qis: Qhov saum npoo yog polished ntawm qib nano, thiab qhov tiv thaiv kev sib cuag nrog cov roj diffusion txheej yog ≤10mΩ·cm², uas txhim kho lub zog tso zis ntawm lub roj cell.
2. Kev tiv thaiv corrosion muaj zog heev, hloov kho tau rau qhov chaw ib puag ncig hnyav
Kev ruaj khov tshuaj lom neeg zoo heev: Nws tuaj yeem tiv taus cov kua qaub muaj zog (xws li phosphoric acid), cov alkalis muaj zog thiab qhov kub thiab txias thiab cov av noo siab, tsis muaj hlau ion precipitation.
Cov txheej txheem tiv thaiv kev oxidation (xaiv tau): Silicon carbide (SiC) txheej tiv thaiv tau ntxiv los ntawm cov txheej txheem CVD, thiab lub neej ntev dua 3 zaug.
3. Tsim qauv sib dua, txo kev siv zog ntawm lub cev
Qhov ceev tsawg li 1.8 g/cm3: sib dua li cov hlau bipolar phaj 20%, tsim nyog rau cov xwm txheej uas rhiab heev rau qhov hnyav xws li cov roj teeb uas ntsia rau hauv tsheb.
Cov qauv nyias nyias: Lub thickness tuaj yeem hloov kho rau 0.8.0-2.0mm, ua kom qhov chaw stacking zoo dua thiab txhim kho lub zog ceev.
4. Lub neej ntev thiab tus nqi kho qis
Lub zog khoov ≥ 40 MPa: Kev tiv thaiv kev cuam tshuam zoo heev, zam kev tawg yooj yim.
Kev tiv thaiv kev nkag mus: Kev ua haujlwm tas mus li rau 10,000 teev ntawm 80 ℃ thiab 95% av noo, kev ua haujlwm poob qis <5%.
Ningbo VET Energy Technology Co., Ltd yog ib lub tuam txhab ua lag luam siab heev uas tsom mus rau kev tsim kho thiab tsim cov khoom siv siab heev, cov ntaub ntawv thiab cov thev naus laus zis suav nrog graphite, silicon carbide, ceramics, kev kho qhov chaw zoo li SiC txheej, TaC txheej, iav carbon txheej, pyrolytic carbon txheej, thiab lwm yam, cov khoom no tau siv dav hauv photovoltaic, semiconductor, lub zog tshiab, metallurgy, thiab lwm yam.
Peb pab neeg kev tshaj lij los ntawm cov tsev kawm tshawb fawb hauv tsev sab saum toj, thiab tau tsim ntau yam thev naus laus zis patented los xyuas kom meej tias cov khoom ua tau zoo thiab zoo, kuj tseem tuaj yeem muab cov neeg siv khoom nrog cov khoom siv tshaj lij.
