1. Te Mātāpono Matua: Te Whakatakotoranga Hiko Whakamuri
Ko te whakakanapa hiko ko te whakarewanga hiko matū o tētahi mea whakarewa i roto i te kaukau irahiko hei tango i te mata o te rauemi, hei whakaiti i te taratara, hei hanga i tētahi āhua kanapa, ngāwari hoki.
Whakaarohia ko tete ritenga kē o te whakakikorua hiko:
● Te whakakikorua hiko: He katote te mea mahi ($-$) → Ngā katote whakarewa mai i te pereti otinga ki runga i te mata.
● Te whakakanapa hiko: He anode te mea mahi ($+$) → Ka waikurahia ngā ngota whakarewa ka tangohia mai i te mata ki roto i te wairewa.
2. Te Kī ki te Whakangawari: Te Papa Rohe Mataotao
Mehemea ka tangohia noa e te whakarewatanga anodic te konganuku, ka haehae noa i te mata. Me pēhea te whakangawari? Kei roto i te paparanga rohe matotoru te whakautu, he ariā matua ki te ariā oro hiko.
● Te hanganga: I te rewatanga o ngā katote konganuku mai i te anode, ka kohikohi rātou ki te paparanga angiangi o te irahiko e tata tonu ana ki te mata o te mea mahi.
● Te Rōrahi Kukū: Ka tino kukū te nui o ngā katote konganuku i roto i tēnei paparanga, ka piki ake tōna matotoru me tōna ātete hiko.
● Tukanga Whakahaere-Tohatoha: Kāore te tere o te whakarewatanga e herea ana e te ngaohiko e whakamahia ana, e te tere o te tauhohenga rānei, engari e te tere o te horapa o ēnei katote konganuku mai i te mata ki roto i te electrolyte papatipu.
3. Te Papa Whakawhāiti i te Au: Te "Wāhi Reka"
Kia mahi ai te oro hiko, me mahi koe i roto i tētahi tikanga hiko matū motuhake: te papatahi iahiko whakawhāiti.
I roto i te kōpiko whakapūtātanga (Kiato o ia Au me te Ngaohiko), ka kite koe i ngā rohe motuhake:
1. Rohe Kaha (Ngaohiko Iti)Ka piki ake te iahiko me te ngaohiko. Ka puta he whakairo whānui, kāore i te whakahaeretia. Hua: He pakarukaru, he āhua mangu.
2. Rohe Pānga/Plateau (Ngaohiko Tino Pai)Ahakoa te pikinga o te ngaohiko, ka mau tonu te au. Ka whakahaere katoa te paparanga matotoru i te horapa. Hua: Te whakakanapa hiko tūturu, te whakangawari rawa, me te whakamārama.
3. Rohe Whakawhiti (Ngaohiko Teitei)Ka hoki anō te au o te iahiko. Ka puta te putanga hāora me te pakaru ā-rohe (te pakaru, te rere o te hau). Hua: Te oro nui rawa, te kino.
Ture whakahaereKia mau tonu te ngaohiko pūtau e pupuri ana i a koe kia mau tonu ki te papatahi.
4. Ngā Tawhā Tukanga Whaihua me ngā Mahanga
Hei whakatutuki i te hua "ruku hohonu" i roto i te mahi, whakahaeretia ēnei taurangi:
● Te pāmahana: Ka whakanui ake i te tere horapa, ka angiangi te paparanga matotoru. Me pupuri kia pumau ($\pm 2^\circ C$). Wera rawa → whakairo. Mātao rawa → e hiahiatia ana te ngaohiko teitei, ka whai kiko.
● Te Kīanga o te Au: Ko te tikanga 10–50 A/$dm^2$. E whakahaua ana e te āhuahanga wāhanga. He iti iho mō ngā wāhanga tairongo.
● Wā: 2–10 meneti noa iho. Kāore i te pai ake te roa; ka pakaru pea te kiri i te oro nui rawa.
● Hoahoa KatoteMe whakaata i te āhua o te wāhanga uaua kia mau tonu ai te tohatoha o te iahiko. He ngoikore te "mana whiu".
Ngā Mahanga Noa me ngā Pūtake Hikohiko Matū:
· Te Rerenga Hau: Te kohua ā-rohe, te putanga hāora rānei (rohe whakawhiti-ā-ringa).
· Kiri Karaka / Putanga KarakaTe mahi i te rohe hohe (he iti rawa te ngaohiko) te electrolyte poke rānei (hei tauira, ngā pūhaumāota).
· Te oro kore taurite: Te whakatakotoranga ngoikore o te katote, te kore rānei e tika te whakaoho o te electrolyte papatipu (kāore e whakakorikori i te paparanga moroiti matotoru engari ka whakahou i te kukū papatipu).
Whakarāpopototanga: Te Akoranga Hikohiko Matū
Ko te whakakanapa hiko he tukanga whakarewatanga anodic e herea ana ki te kawe papatipu. Kāore e tutuki te mutunga maeneene mā te "tahu atu" i ngā tihi engari mā te whakatū i tētahi paparanga rohe matotoru pumau, ātete e hanga ana i te tere whakarewatanga teitei ake i ngā āhuatanga mata e puta ake ana. Mā te mahi tika i runga i te papa iahiko whakawhāiti, me te electrolyte waikawa kua whakaritea, ka puta he mata he maeneene ake, he ma, he ngāwari ake i tētahi atu huarahi miihini.
