He aha ngā pākahiko kawakore?

Ngā pākahiko kawakoreHe momo pākahiko whakakorekore ēnei e whakamahi ana i te electrolyte kawakore o te pāhare pākawa waro. He mea whakamahi noa ēnei i roto i te whānuitanga o ngā taputapu, pērā i ngā mana mamao, ngā rama rama, ngā taonga takaro, me ētahi atu taputapu. E mōhiotia ana ngā pākahiko kawakore mō te roa o te wā e whakamahia ana, me te kaha ki te whakarato i te putanga hiko pumau i roto i te wā. He maha ngā wā ka tohua ēnei ki tētahi waehere reta pērā i te AA, AAA, C, D rānei, e tohu ana i te rahi me te momo o te pākahiko.

He aha ngā wāhanga o ngā pākahiko kawakore?

He maha ngā wāhanga matua o ngā pākahiko kawakore, tae atu ki:

Cathode: Ko te cathode, e mohiotia ana ko te pito pai o te pākahiko, he mea hanga i te konupora hauhā, ā, koia te wāhi o ngā tauhohenga matū o te pākahiko.

Anode: Ko te anode, te pito kino rānei o te pākahiko, he mea hanga i te paura konutea, ā, koia te pūtake o ngā irahiko i te wā e tukuna ana te pākahiko.

Irahikohiko: Ko te irahikohiko i roto i ngā pākahiko kawakore he otinga pāhare pākawa waro e āhei ai te whakawhiti i ngā katote i waenga i te katote me te anote, e āhei ai te rere o te iahiko hiko.

Wehewehe: Ko te wehewehe he rauemi e wehewehe ā-tinana ana i te katote me te anode i roto i te pākahiko, me te tuku hoki i ngā katote kia haere mā roto hei pupuri i te mahi a te pākahiko.

Te anga: Ko te anga o waho o te pākahiko kawakore he mea hanga ki te konganuku, ki te kirihou rānei, ā, hei pupuri me te tiaki i ngā wāhanga o roto o te pākahiko.

Pūtake: Ko ngā pūtake o te pākahiko ngā pūwāhi whakapā pai me kino e taea ai te hono i te pākahiko ki tētahi pūrere, e whakaoti ana i te ara iahiko, e āhei ai hoki te rere o te hiko.
He aha ngā tauhohenga matū e puta ana i roto i ngā pākahiko kawakore ina tukuna te hiko

I roto i ngā pākahiko kawakore, ka puta ngā tauhohenga matū e whai ake nei ina tukuna te pākahiko:

I te katote (pito pai):
MnO2 + H2O + e- → MnOOH + OH-

I te anode (pito kino):
Zn + 2OH- → Zn(OH)2 + 2e-

Tauhohenga whānui:
Zn + MnO2 + H2O → Zn(OH)2 + MnOOH

I roto i ngā kupu māmā noa iho, i te wā e tukuna ana, ka tauhohe te konutea i te anode ki ngā katote hauwai (OH-) i roto i te electrolyte hei hanga i te konutea hauwai (Zn(OH)2) ka tukuna ngā irahiko. Ka rere ēnei irahiko mā te ara iahiko o waho ki te katote, te wāhi ka tauhohe te hauhā manganese (MnO2) ki te wai, ā, ka hanga ngā irahiko i te hauwai manganese (MnOOH) me ngā katote hauwai. Mā te rere o ngā irahiko mā te ara iahiko o waho ka hangaia he pūngao hiko ka taea te whakakaha i tētahi taputapu.
Me pēhea te mōhio mēnā he pai te kounga o ngā pākahiko kawakore a tō kaiwhakarato

Hei whakatau mēnā ko tōngā pākahiko kawakore a te kaiwhakaratohe kounga pai, whakaarohia ēnei āhuatanga:

Rongonui o te waitohu: Kōwhiria ngā pākahiko mai i ngā waitohu rongonui me te rongonui e mōhiotia ana mō te hanga hua kounga teitei.

Mahi: Whakamātauria ngā pākahiko i roto i ngā momo taputapu kia tino rite, kia pono hoki te putanga hiko i roto i te wā.

Te Roa o te Ora: Rapua ngā pākahiko kawakore he roa te wā e ora ai, kia roa ai te wā e mau tonu ai te utu ina tiakina tika.

Te Pūngao: Tirohia te whakatauranga pūngao o ngā pākahiko (e inehia ana i roto i te mAh) kia mōhio ai he nui te rokiroki pūngao mō ō hiahia.

Te Pakari: Arotakehia te hanganga o ngā pākahiko kia tino pai te hanga, kia tu atu hoki i te whakamahinga noa, me te kore e turuturu, e pakaru rānei i te wā wawe.

Te tutuki i ngā paerewa: Me whakarite kia ora ngā pākahiko o teKaiwhakarato pākahiko kawakorekia tutuki i ngā paerewa haumaru me te kounga e tika ana, pērā i ngā tiwhikete ISO, te tutuki rānei i ngā ture pērā i te RoHS (Restriction of Moldous Substances).

Arotake a te kiritaki: Whakaarohia ngā urupare a ētahi atu kiritaki, a ngā tohunga rānei o te umanga hei aromatawai i te kounga me te pono o ngā pākahiko kawakore a te kaiwhakarato.

Mā te aromatawai i ēnei āhuatanga me te whakahaere i ngā whakamātautau me ngā rangahau hōhonu, ka taea e koe te whakatau pai ake mēnā he kounga pai ngā pākahiko kawakore a tō kaiwhakarato, ā, he tika hoki mō ō hiahia.
