Ko ngā pākahiko kawakore he momo pākahiko hikohiko noa e whakamahi ana i te hanganga pākahiko waro-konutea e whakamahia ana te pāhare pākawa hei irahiko. He mea noa te whakamahi i ngā pākahiko kawakore i roto i ngā taputapu e hiahia ana ki te pūtake hiko pumau mō te wā roa, ā, ka taea te mahi i ngā pāmahana tiketike me te iti, pērā i ngā kaiwhakahaere, ngā whakawhiti reo irirangi, ngā rama, me ētahi atu.
1. Te kaupapa o te whakahaere i ngā pākahiko kawakore
Ko te pākahiko kawakore he pākahiko pūtau maroke whakapoto-katote, he mea tito mai i te anode konutea, he katote hauhā manganese me te electrolyte hauwai pāhare pākawa.
I roto i te pākahiko kawakore, ka tauhohe te electrolyte pāhare pākawa waro hei whakaputa i ngā katote hauwai me ngā katote pāhare pākawa. Ina whakakahangia te pākahiko, ka puta he tauhohenga redox i waenga i te anode me te cathode ka puta he whakawhiti utu. Ina koa, ina pāngia te matrix konutea Zn e te tauhohenga waikura, ka tukuna ngā irahiko ka rere mā roto i te ara iahiko o waho ka tae ki te cathode MnO2 o te pākahiko. I reira, ka whai wāhi ēnei irahiko ki te tauhohenga redox toru-irahiko i waenga i te MnO2 me te H2O i roto i te tukunga o te hāora.
2. Ngā Āhuatanga o ngā Pūhiko Kawakore
Ko ngā āhuatanga o ngā pākahiko kawakore e whai ake nei:
Te matotoru o te pūngao - ka taea te whakarato i te mana pumau mō te wā roa
He roa te ora - ka taea te penapena mō ngā tau maha i te wā kāore i whakamahia
Te pumau teitei - ka taea te mahi i roto i ngā taiao pāmahana teitei me te pāmahana iti.
He iti te tere tukunga-ā-unoa - kāore he ngaronga pūngao i roto i te wā
He haumaru - kāore he raruraru turuturu
3. Ngā whakatūpato mō te whakamahi i ngā pākahiko kawakore
I te wā e whakamahi ana i ngā pākahiko kawakore, me mātua whai i ngā āhuatanga e whai ake nei:
- Kaua e whakaranua ki ētahi atu momo pākahiko hei karo i ngā raruraru ara iahiko poto me te turuturu.
- Kaua e patua, e kuru, e ngana rānei ki te wetewete, ki te whakarerekē rānei i ngā pākahiko.
- Me pupuri te pākahiko ki te wāhi maroke, hauhautanga hoki i te wā e rongoa ana.
- Ina pau te pākahiko, me whakakapi ki tētahi mea hou i te wā tika, ā, kaua e maka atu te pākahiko kua whakamahia.
