ʻO nā Bateri Vanadium Redox Flow (VFBs)he ʻenehana hoʻopaʻa ikehu e kū nei me ka mana nui, ʻoi aku ka nui o nā noi mālama mālama lōʻihi. ʻAʻole like me ka maʻamauhoʻopaʻa pākaukau rechargeable, Hoʻohana nā VFB i kahi hopena electrolyte vanadium no nā electrodes maikaʻi a maikaʻi ʻole, e hoʻokaʻawale iā lākou i ka hoʻolālā a me ka hana.
He aha ka Vanadium Redox Flow Battery?
ʻO kavanadium redox pākaukau (VRB), ʻike ʻia hoʻi ʻo ka vanadium flow battery (VFB) a i ʻole vanadium redox flow battery (VRFB), he ʻano o ka pahu kahe e hoʻihoʻi hou ʻia.
Hoʻohana ʻo ia i nā ion vanadium i nā mokuʻāina oxidation e mālama a hoʻokuʻu i ka ikehu uila. ʻAʻole e like me nā pākaukau maʻamau, mālama ʻo VRFB i ka ikehu i loko o nā electrolytes wai e kahe ana ma ka ʻōnaehana ma mua o nā electrodes paʻa. Hāʻawi kēia hoʻolālā i ka scalable a maʻalahinā hāʻina mālama ikehu.
ʻO nā ʻāpana koʻikoʻi o kahi pākaukau Vanadium Redox Flow
| Mea Ki | wehewehe |
| ʻElectrolytes | - Hoʻohana ʻo VRFB i ʻelua mau electrolytes wai, maʻamau i loaʻa i ka vanadium i loko o nā kūlana hoʻokahe like ʻole (V²⁺, V³⁺, V⁴⁺, a me V⁵⁺). |
| Nā uila uila | - ʻElua mau electrodes (ka maʻamau kalapona a i ʻole nā mea like) e hoʻomaʻamaʻa i ka redox reactions (hoʻemi a me ka oxidation) e hoʻokuʻu a mālama i ka ikehu. |
| Membrane | - Ua hoʻokaʻawale ʻia nā ʻāpana electrolyte ʻelua i ka proton-conducting membrane (i hana pinepine ʻia me Nafion), e ʻae ana i ka holo ʻana o ka ion ma waena o nā ʻaoʻao ʻelua i ka wā o ke kaʻina hoʻoiho. |
| Nā Pum a me ka Pūnaehana kahe | - Hoʻopili kēia mau ʻāpana i nā electrolytes ma o ke kelepona electrochemical, e hōʻoiaʻiʻo ana i ka holo mau ʻana o nā ion vanadium no ka hoʻololi ʻana i ka ikehu. |
Pehea ka hana ʻana o kahi pākaukau Vanadium Redox Flow?
- 1. Hoʻokuʻu ʻia
- I ka wā o ka hoʻokuʻu ʻana, ʻo nā ion vanadium i loko o nā hopena electrolyte maikaʻi a maikaʻi ʻole e hoʻemi i ka hopena a me ka hoʻohaʻahaʻa ʻana i nā electrodes, e hoʻokuʻu ana i ka ikehu uila.
- 2. Kaapuni Hoʻoili
- I ka wā o ka hoʻouka ʻana, mālama ʻia ka ikehu ma ka hoʻohuli ʻana i ka hopena o ka oxidation a me ka hoʻohaʻahaʻa ʻana, e hoʻihoʻi i nā ion vanadium i ko lākou mau kūlana oxidation mua. ʻO kēia kaʻina hana e pili ana i ka hoʻopili ʻana i kahi au o waho i ka ʻōnaehana.
- 3. Nā Electrolytes Kahe
- ʻO ka hiʻohiʻona koʻikoʻi o nā pihi kahe, ʻo ia ka hoʻohana ʻana i nā electrolytes wai i puhi ʻia ma o ka ʻōnaehana, e hiki ai ke hoʻonui maʻalahi i ka hiki o ka pākaukau ma ka hoʻonui wale ʻana i ka nui o nā pahu mālama electrolyte.
Nā Pōmaikaʻi o nā Bateri Vanadium Redox Flow
- √ Scalability
Hiki ke hoʻonui maʻalahi i nā VRFB ma o ka hoʻonui ʻana i ka nui o nā pahu electrolyte, e hoʻolilo iā lākou i mea kūpono no nā noi mālama ikehu nui e like me ke kaulike grid a me ka mālama ʻana i ka ikehu hou. - √ Ola Kaapuni loihi
ʻAʻole hoʻohaʻahaʻa ʻo Vanadium i ka wā kaʻa (no ka mea, hoʻohana ʻo ia i nā mea like no nā electrolytes maikaʻi a maikaʻi ʻole), e hāʻawi ana i nā VRFB i ke ola hana lōʻihi e hoʻohālikelike ʻia me nā mea kemika ʻē aʻe.
