Amabhethri e-alkaline awuhlobo oluvamile lwebhethri le-electrochemical elisebenzisa ukwakhiwa kwebhethri le-carbon-zinc lapho kusetshenziswa khona i-potassium hydroxide njenge-electrolyte. Amabhethri e-alkaline avame ukusetshenziswa kumadivayisi adinga ukunikezwa kwamandla okuzinzile isikhathi eside futhi akwazi ukusebenza kokubili emazingeni okushisa aphezulu naphansi, njengezilawuli, ama-transceiver omsakazo, amathoshi, njll.
1. Isimiso sokusebenza kwamabhethri e-alkaline
Ibhethri le-alkaline liyibhethri le-dry cell elifinyeza ama-ion eliqukethe i-zinc anode, i-manganese dioxide cathode kanye ne-potassium hydroxide electrolyte.
Ebhethrini le-alkaline, i-potassium hydroxide electrolyte iyasabela ukuze ikhiqize ama-ion e-hydroxide nama-ion e-potassium. Lapho ibhethri linikwa amandla, kwenzeka ukusabela kwe-redox phakathi kwe-anode ne-cathode okuholela ekudlulisweni kweshaja. Ikakhulukazi, lapho i-Zn zinc matrix idlula ekusabela kwe-oxidation, izokhipha ama-electron azogeleza ngesekethe yangaphandle futhi afinyelele ku-MnO2 cathode yebhethri. Lapho, lawa ma-electron azohlanganyela ekusabela kwe-redox kwama-electron amathathu phakathi kwe-MnO2 ne-H2O ekukhishweni komoya-mpilo.
2. Izici Zamabhethri E-Alkaline
Amabhethri e-alkaline anezici ezilandelayo:
Ubuningi bamandla aphezulu - kunganikeza amandla azinzile isikhathi eside
Impilo ende yeshelufu - ingagcinwa iminyaka eminingi esimweni esingasetshenziswa
Ukuqina okuphezulu - kungasebenza kokubili ezindaweni zokushisa eziphakeme neziphansi.
Izinga eliphansi lokuzikhipha - akukho ukulahlekelwa amandla ngokuhamba kwesikhathi
Kuphephile kakhulu - azikho izinkinga zokuvuza
3. Izinyathelo zokuphepha zokusebenzisa amabhethri e-alkaline
Uma usebenzisa amabhethri e-alkaline, qiniseka ukuthi uqaphela amaphuzu alandelayo:
- Ungazixubi nezinye izinhlobo zamabhethri ukuze ugweme izinkinga ze-short circuit kanye nokuvuza.
- Ungazishayi ngamandla, uzichoboze noma uzame ukuzihlukanisa noma ukushintsha amabhethri.
- Sicela ugcine ibhethri endaweni eyomile nepholile uma uligcina.
- Uma ibhethri seliphelile, sicela ulishintshe ngelisha ngesikhathi futhi ungalilahli ibhethri elisetshenzisiwe.
