Te Mahi a ngā Pūhiko Rere Redox

Ko te wehenga o te mana me te pūngao tētahi o ngā rerekētanga matua o ngā RFB, ki te whakatauritea ki ētahi atungā pūnaha rokiroki hikohiko. E ai ki te whakaahuatanga i runga ake nei, kei roto te pūngao o te pūnaha i te rōrahi o te electrolyte, ka taea te noho ngāwari me te ōhanga i roto i te whānuitanga o te kilowatt-haora ki ngā tekau megawatt-haora, i runga i te rahi ongā tāke rokiroki. Ko te kaha o te pūnaha ka whakatauhia e te rahi o te puranga o ngā pūtau hikohiko. Ko te nui o te irahiko e rere ana i roto i te puranga hikohiko i tētahi wā kāore i te nui atu i te torutoru ōrau o te tapeke o te irahiko kei reira (mō ngā whakatauranga pūngao e rite ana ki te tukunga i te mana whakatauranga mō te rua ki te waru hāora). Ka taea te aukati ngāwari i te rere i te wā o te āhuatanga hapa. Nō reira, ko te ngoikore o te pūnaha ki te tukunga pūngao kāore i te whakahaeretia i roto i te take o ngā RFB ka whakawhāitihia e te hoahoa pūnaha ki te torutoru ōrau o te tapeke o te pūngao kua rongoatia. He rerekē tēnei āhuatanga ki ngā hoahoa rokiroki pūtau kua tākaihia, kua whakauruhia (waikawa-mata, NAS, Li Ion), kei reira te pūngao katoa o te pūnaha e hono ana i ngā wā katoa, ā, e wātea ana mō te tukunga.

Mā te wehenga o te mana me te pūngao ka taea hoki te whakarite i te ngāwari o te hoahoa i roto i te tono o ngā RFB. Ka taea te whakarite tika i te kaha o te mana (te rahi o te puranga) ki te kawenga e pā ana, ki te rawa whakaputa rānei. Ka taea te whakarite motuhake i te kaha rokiroki (te rahi o ngā tāke rokiroki) ki te hiahia rokiroki pūngao o te tono motuhake. Mā tēnei, ka taea e ngā RFB te whakarato i tētahi pūnaha rokiroki kua arotauhia mō ia tono. He rerekē, ko te ōwehenga o te mana ki te pūngao kua whakaritea mō ngā pūtau whakauru i te wā e hoahoahia ana me te hanga o ngā pūtau. Ko ngā ōhanga tauine i roto i te hanga pūtau ka whakawhāiti i te maha o ngā hoahoa pūtau rerekē e wātea ana. Nō reira, ko ngā tono rokiroki me ngā pūtau whakauru ka nui ake te kaha, te kaha pūngao rānei.

E rua ngā wāhanga o ngā RFB: 1) ponongā pākahiko rere redox, kei reira ngā momo matū katoa e kaha ana ki te penapena pūngao ka rewa katoa i roto i te wairewa i ngā wā katoa; me te 2) ngā pākahiko rere redox ranu, kei reira te iti rawa o te kotahi momo matū ka whakakikoruatia hei totoka i roto i ngā pūtau hikohiko i te wā e utua ana. Ko ngā tauira o ngā RFB tūturu kongā pūnaha vanadium-vanadium me te rino-chromiumKo ngā tauira o ngā RFB ranu ko ngā pūnaha konutea-pūromine me te konutea-pūhaumāota.
