Empilweni yanamuhla, amabhethri aseyingxenye ebalulekile yempilo yethu yansuku zonke, kanye nokukhetha phakathiamabhethri e-alkalinefuthi amabhethri avamile owomile avame ukubadida abantu. Lesi sihloko sizoqhathanisa futhi sihlaziye izinzuzo zamabhethri e-alkaline namabhethri avamile owomile ukuze sikusize uqonde kangcono umehluko phakathi kwawo.
Okokuqala, ake siqhathanise isakhiwo seamabhethri e-alkalinekanye neyamabhethri avamile omile. Amabhethri avamile omile avame ukusebenzisa isakhiwo se-monolithic, kanye nezinto zokuhlukanisa ezihlukanisa ama-electrode amabili. Nakuba lo mklamo ulula, ukusebenza kwebhethri kanye nesikhathi sokuphila kuphansi kakhulu. Ngokuphambene nalokho, amabhethri e-alkaline asebenzisa isakhiwo samaseli amaningi ukuthuthukisa ukusebenza kwebhethri kanye nesikhathi sokuphila. Lo mklamo uvumela amabhethri e-alkaline ukuthi asebenzise kangcono ukusabela kwamakhemikhali, anikeze ukunikezwa kwamandla okusimeme kakhudlwana.
Okulandelayo, ake sibheke umehluko ekwakhiweni kwamakhemikhali phakathi kwalokhu okubili. I-electrolyte yamabhethri avamile omile ngokuvamile iyinto eqinile ye-alkaline, njenge-zinc chloride noma i-ammonium carbamate. Ngakolunye uhlangothi, amabhethri e-alkaline asebenzisa izinto ze-alkaline njenge-potassium hydroxide noma i-potassium hydroxide njenge-electrolyte. Lo mehluko wenza i-electrolyte yamabhethri e-alkaline ibe namandla aphezulu, ngakho-ke amandla amabhethri e-alkaline makhulu, okuhlinzeka ngokunikezwa kwamandla okuhlala isikhathi eside.
Ngaphezu kwalokho, amabhethri e-alkaline nawo asebenza kahle kakhulu kunamabhethri omile avamile ngokusebenza kwawo. Njengoba i-potassium hydroxide kumabhethri e-alkaline iwuketshezi, ukumelana kwangaphakathi kuncane kakhulu, kukhiqiza amandla kagesi afinyelela ku-3-5 kunebhethri elinobukhulu obufanayo. Lokhu kusho ukuthi amabhethri e-alkaline anganikeza amandla kagesi amakhulu ukuhlangabezana nezidingo zamadivayisi adinga amandla kagesi aphezulu. Ngaphezu kwalokho, amabhethri e-alkaline awakhiqizi igesi ngesikhathi sokukhishwa, futhi amandla kagesi azinzile. Ngakolunye uhlangothi, amabhethri omile avamile akhiqiza igesi ethile ngesikhathi sokukhishwa, okubangela ukungabi namandla kwamandla kagesi.
Ngokuphathelene nokuqina, amabhethri e-alkaline nawo anezinzuzo ezibalulekile. Njengoba i-zinc kumabhethri e-alkaline ihlanganyela ekusabeleni njengezingcezu ezifana nezinhlayiya ezinendawo enkulu yokuxhumana ne-electrolyte, ikhiqiza ugesi omkhulu futhi inokuphila isikhathi eside kwenkonzo. Kodwa-ke, amabhethri avamile omile anesilinganiso esisheshayo sokubola komthamo kanye nokuphila kwenkonzo okufushane. Ngakho-ke, ekusetshenzisweni kwesikhathi eside noma okuvame kakhulu, amabhethri e-alkaline ayisinqumo esingcono.
Ngamafuphi, amabhethri e-alkaline asebenza kahle kakhulu futhi aphila isikhathi eside uma kuqhathaniswa namabhethri avamile omile. Kungakhathaliseki ukuthi kumayelana nomthamo, ukuphuma kwamanje, ukuzinza kwamandla kagesi, noma ukuqina, amabhethri e-alkaline abonisa izinzuzo ezibalulekile. Ngakho-ke, empilweni yansuku zonke, kufanele sikhethe ukusebenzisa amabhethri e-alkaline ukuze sithole ukunikezwa kwamandla okuzinzile nokuzinzile.
