Ayini amabhethri e-Alkaline?

Amabhethri ane-alkalineziwuhlobo lwebhethri elilahlwayo elisebenzisa i-alkaline electrolyte ye-potassium hydroxide. Avame ukusetshenziswa ezinhlobonhlobo zemishini, njengezilawuli kude, amathoshi, amathoyizi, namanye amagajethi. Amabhethri e-alkaline aziwa ngempilo yawo ende yeshelufu kanye nekhono lokuhlinzeka ngokuphuma kwamandla okungaguquki ngokuhamba kwesikhathi. Ngokuvamile zilebula ngekhodi yezinhlamvu ezifana ne-AA, AAA, C, noma D, ebonisa usayizi nohlobo lwebhethri.

Yiziphi izingxenye zamabhethri e-alkaline?

Amabhethri e-alkaline aqukethe izingxenye ezimbalwa ezibalulekile, okuhlanganisa:

I-Cathode: I-cathode, eyaziwa nangokuthi isiphetho esihle sebhethri, ngokuvamile yenziwe nge-manganese dioxide futhi isebenza njengendawo yokusabela kwamakhemikhali ebhethri.

I-anode: I-anode, noma isiphetho esinegethivu sebhethri, ngokuvamile sakhiwe nge-zinc eyimpuphu futhi sisebenza njengomthombo wama-electron phakathi nenqubo yokukhipha ibhethri.

I-Electrolyte: I-electrolyte kumabhethri e-alkaline yisisombululo se-potassium hydroxide esivumela ukudluliswa kwama-ion phakathi kwe-cathode ne-anode, okuvumela ukugeleza kwamandla kagesi.

Isihlukanisi: Isihlukanisi into ehlukanisa i-cathode ne-anode ngaphakathi kwebhethri kuyilapho ivumela ama-ion ukuthi adlule ukuze kugcinwe ukusebenza kwebhethri.

Ikesi: Ikesi yangaphandle yebhethri ye-alkaline ngokuvamile yenziwe ngensimbi noma ngepulasitiki futhi isebenza ngokuqukatha nokuvikela izingxenye zangaphakathi zebhethri.

Itheminali: Amatheminali ebhethri yizindawo zokuxhumana eziphozithivu nezinegethivu ezivumela ibhethri ukuthi lixhumeke kudivayisi, ukuqedela umjikelezo kanye nokuvumela ukuhamba kukagesi.
Kwenzekani Ukusabela Kwekhemikhali Kumabhethri E-alkaline Lapho Ekhishwa

Kumabhethri e-alkaline, ukusabela kwamakhemikhali okulandelayo kwenzeka lapho ibhethri likhishwa:

Ku-cathode (ekupheleni okuhle):
MnO2 + H2O + e- → MnOOH + OH-

Esikhathini se-anode (esiphethweni esibi):
Zn + 2OH- → Zn(OH)2 + 2e-

Ukusabela sekukonke:
Zn + MnO2 + H2O → Zn(OH)2 + MnOOH

Ngamagama alula, ngesikhathi sokukhishwa, i-zinc ku-anode ihlangana nama-ion we-hydroxide (OH-) ku-electrolyte ukwenza i-zinc hydroxide (Zn(OH)2) futhi ikhulule ama-electron. Lawa ma-electron ageleza kumjikelezo wangaphandle aye ku-cathode, lapho i-manganese dioxide (MnO2) isabela emanzini kanye nama-electron ukuze akhe i-manganese hydroxide (MnOOH) nama-ion we-hydroxide. Ukugeleza kwama-electron ngomjikelezo wangaphandle kudala amandla kagesi anganika idivayisi amandla.
Ungazi kanjani ukuthi amabhethri e-alkaline omhlinzeki wakho ayikhwalithi enhle yini

Ukuze unqume ukuthi eyakhoamabhethri e-alkaline omphakeliezekhwalithi enhle, cabangela izici ezilandelayo:

Isithunzi sebhrendi: Khetha amabhethri ezinkampanini ezidumile nezinegama elihle elaziwa ngokukhiqiza imikhiqizo yekhwalithi ephezulu.

Ukusebenza: Hlola amabhethri kumadivayisi ahlukahlukene ukuze uqinisekise ukuthi ahlinzeka ngokuphuma kwamandla okungaguquki futhi okuthembekile ngokuhamba kwesikhathi.

Ubude bokuphila: Bheka amabhethri e-alkaline aneshelufu ende yempilo ukuze uqinisekise ukuthi azogcina ukushajwa kwawo isikhathi eside uma egcinwe kahle.

Amandla: Hlola isilinganiso somthamo wamabhethri (ngokuvamile akalwa nge-mAh) ukuze uqinisekise ukuthi anesitoreji samandla esanele sezidingo zakho.

Ukuqina: Hlola ukwakhiwa kwamabhethri ukuze uqiniseke ukuthi enziwe kahle futhi angakwazi ukumelana nokusetshenziswa okuvamile ngaphandle kokuvuza noma ukwehluleka ngaphambi kwesikhathi.

Ukuthobelana namazinga: Qinisekisa amabhethri weUmhlinzeki wamabhethri ane-alkaliukuhlangabezana namazinga afanele okuphepha kanye nekhwalithi, njengezitifiketi ze-ISO noma ukuhambisana nemithethonqubo efana ne-RoHS (Umkhawulo Wezinto Eziyingozi).

Izibuyekezo zekhasimende: Cabangela impendulo evela kwamanye amakhasimende noma ochwepheshe bemboni ukuze ulinganise ikhwalithi nokuthembeka kwamabhethri e-alkaline omphakeli.

Ngokuhlola lezi zici nokwenza ukuhlola nokucwaninga okuphelele, ungathola kangcono ukuthi amabhethri e-alkaline omphakeli wakho awekhwalithi enhle futhi afanele izidingo zakho.
