He aha ka pākahiko Alkaline?

1.Kumumanaʻo o ka hana ʻana o nā pila alkaline

ʻO ka pākahiko alkaline kahi pākahiko maloʻo e hoʻopōkole ana i ka ion i hana ʻia me kahi anode zinc, kahi cathode manganese dioxide a me kahi electrolyte potassium hydroxide.

I loko o kahi pākahiko alkaline, hana ka electrolyte potassium hydroxide e hana i nā ion hydroxide a me nā ion potassium. Ke hoʻoikaika ʻia ka pākahiko, hana ʻia kahi hopena redox ma waena o ka anode a me ka cathode e hopena ana i ka hoʻoili ʻana o ka uku. ʻOi aku hoʻi, i ka wā e hana ai ka matrix Zn zinc i kahi hopena oxidation, e hoʻokuʻu ia i nā electrons e kahe ana ma o ke kaapuni waho a hiki i ka cathode MnO2 o ka pākahiko. Ma laila, e komo kēia mau electrons i kahi hopena redox ʻekolu-electron ma waena o MnO2 a me H2O i ka hoʻokuʻu ʻana o ka oxygen.

2. Nā ʻano o nā pila Alkaline

Loaʻa i nā pila alkaline nā ʻano penei:

Ka nui o ka ikehu - hiki ke hāʻawi i ka mana paʻa no ka manawa lōʻihi

Ola lōʻihi - hiki ke mālama ʻia no nā makahiki he nui i kahi mokuʻāina i hoʻohana ʻole ʻia

Kūlana paʻa kiʻekiʻe - hiki ke hana ma nā wahi wela kiʻekiʻe a me ka haʻahaʻa.

Haʻahaʻa ka helu hoʻokuʻu ponoʻī - ʻaʻohe nalowale o ka ikehu i ka hala ʻana o ka manawa

Palekana iki - ʻaʻohe pilikia leakage

3. Nā akahele no ka hoʻohana ʻana i nā pila alkaline

I ka wā e hoʻohana ai i nā pila alkaline, e mālama pono i kēia mau mea:

- Mai hoʻohui iā lākou me nā ʻano pila ʻē aʻe e pale aku i nā pilikia kaapuni pōkole a me ka leakage.

- Mai kuʻi ikaika, kuʻi a hoʻāʻo paha e wehewehe iā lākou a hoʻololi paha i nā pila.

- E ʻoluʻolu e mālama i ka pila ma kahi maloʻo a me kahi anu i ka wā e mālama ai.

- Ke pau ka pila, e hoʻololi iā ia me kahi mea hou i ka manawa kūpono a mai hoʻolei aku i ka pila i hoʻohana ʻia.
