He aha ke ʻano o nā ʻakika Alkaline?

ʻO nā ʻanuʻu alkalineHe ʻano pākaukau hoʻopau ʻia e hoʻohana ana i kahi electrolyte alkaline o ka pāhaʻi hydroxide. Hoʻohana mau ʻia lākou i nā ʻano mea like ʻole, e like me nā mana mamao, nā kukui uila, nā mea pāʻani, a me nā hāmeʻa ʻē aʻe. Ua ʻike ʻia nā pākahi alkaline no ka lōʻihi o ke ola a me ka hiki ke hāʻawi i ka mana o ka mana i ka manawa. Hoʻopaʻa inoa ʻia lākou me kahi helu leka e like me AA, AAA, C, a i ʻole D, e hōʻike ana i ka nui a me ke ʻano o ka pākaukau.

He aha nā ʻāpana o nā pākahi alkaline?

Aia kekahi mau mea ko'iko'i i loko o nā pilaki alkaline, me:

Cathode: ʻO ka cathode, ka mea i ʻike ʻia ʻo ka hopena maikaʻi o ka pākaukau, i hana maʻamau ʻia me ka manganese dioxide a lawelawe ʻo ia ma ke ʻano o nā hopena kemika o ka pā.

Anode: ʻO ka anode, a i ʻole ka hopena maikaʻi ʻole o ka pākaukau, ka mea maʻamau i haku ʻia me ka pauda zinc a hana ʻo ia ke kumu o nā electrons i ka wā o ka hoʻokuʻu ʻana o ka pākaukau.

Electrolyte: ʻO ka electrolyte i loko o nā ʻāpana alkaline he hopena potassium hydroxide e hiki ai ke hoʻololi i nā ion ma waena o ka cathode a me ka anode, e hiki ai ke kahe o ke au uila.

Separator: ʻO ka mea hoʻokaʻawale kahi mea e hoʻokaʻawale kino ai i ka cathode a me ka anode i loko o ka pākaukau me ka ʻae ʻana i nā ion e hele i loko e mālama i ka hana o ka pā.

Casing: ʻO ka pahu o waho o kahi pākaukau alkaline i hana maʻamau i ka metala a i ʻole ka plastic a lawelawe ʻia e hoʻopaʻa a pale i nā ʻāpana o loko o ka pā.

Terminal: ʻO nā pauku o ka pākaukau nā wahi hoʻopili maikaʻi a maikaʻi ʻole e hiki ai i ka pākaukau ke hoʻopili ʻia i kahi mea hana, hoʻopau i ke kaapuni a hiki i ke kahe ʻana o ka uila.
He aha ka hopena kemika i loko o nā Batteri Alkaline ke hoʻokuʻu ʻia

I loko o nā ʻakika alkaline, hiki mai nā hopena kemika i ka wā i hoʻokuʻu ʻia ai ka pila:

Ma ka cathode (hopena maikaʻi):
MnO2 + H2O + e- → MnOOH + OH-

Ma ka anode (hopena ino):
Zn + 2OH- → Zn(OH)2 + 2e-

Pane holoʻokoʻa:
Zn + MnO2 + H2O → Zn(OH)2 + MnOOH

Ma nā huaʻōlelo maʻalahi, i ka wā o ka hoʻokuʻu ʻana, hana ka zinc ma ka anode me nā ion hydroxide (OH-) i ka electrolyte e hana i ka zinc hydroxide (Zn(OH)2) a hoʻokuʻu i nā electrons. Ke holo nei kēia mau electrons ma ke kaapuni waho i ka cathode, kahi e hana ai ka manganese dioxide (MnO2) me ka wai a me nā electrons e hana i ka manganese hydroxide (MnOOH) a me nā ion hydroxide. ʻO ke kahe o nā electrons ma o ke kaapuni waho e hana i ka ikehu uila hiki ke hoʻoikaika i kahi mea hana.
Pehea e ʻike ai inā ʻoi aku ka maikaʻi o nā pākahi alkaline o kāu mea hoʻolako

No ka hoʻoholo inā ʻoenā ʻakika alkaline o ka mea hoʻolakomaikaʻi ka maikaʻi, e noʻonoʻo i kēia mau mea:

Kaulana inoa: E koho i nā ʻona mai nā hōʻailona i hoʻokumu ʻia a kaulana i ʻike ʻia no ka hana ʻana i nā huahana kiʻekiʻe.

Hana: E ho'āʻo i nā pila ma nā mea like ʻole e hōʻoia i ka hāʻawi ʻana i ka mana kūpono a hilinaʻi hoʻi i ka manawa.

Ka lōʻihi: E ʻimi i nā pākaukau alkaline me ka lōʻihi o ke ola ʻana e hōʻoia i ka mālama ʻana i kā lākou uku no ka manawa lōʻihi ke mālama pono ʻia.

Kaha: E nānā i ka helu kaha o nā pila (e ana mau ʻia i ka mAh) e hōʻoia i ka lawa o ka mālama ʻana i ka ikehu no kāu mau pono.

Ka lōʻihi: E noʻonoʻo i ke kūkulu ʻia ʻana o nā pila e hōʻoia i ka hana maikaʻi ʻia a hiki ke kūpaʻa i ka hoʻohana maʻamau me ka ʻole o ka hoʻoheheʻe ʻana a i ʻole ka hāʻule mua ʻana.

Hoʻokō i nā kūlana: E hōʻoia i nā ʻeke o kaMea hoʻolako pākiʻi alkalinee hoʻokō i nā kūlana palekana kūpono a me ka maikaʻi, e like me ka ISO certifications a i ʻole ka hoʻokō ʻana i nā lula e like me RoHS (Restriction of Hazardous Substances).

Nā manaʻo o nā mea kūʻai aku: E noʻonoʻo i nā manaʻo mai nā mea kūʻai aku a i ʻole nā ​​​​mea ʻoihana ʻoihana e ana i ka maikaʻi a me ka hilinaʻi o nā pā alkaline o ka mea hoʻolako.

Ma ka loiloi ʻana i kēia mau mea a me ka hoʻāʻo ʻana a me ka noiʻi ʻana, hiki iā ʻoe ke hoʻoholo maikaʻi inā maikaʻi nā pākaʻi alkaline o kāu mea hoʻolako a kūpono i kāu mau koi.
