Empilweni yanamuhla, amabhethri abe yingxenye ebalulekile yokuphila kwethu kwansuku zonke, kanye nokukhetha phakathiamabhethri e-alkalinenamabhethri omile ajwayelekile avame ukudida abantu. Lesi sihloko sizoqhathanisa futhi sihlaziye izinzuzo zamabhethri e-alkaline namabhethri omile ajwayelekile ukuze sikusize uqonde kangcono umehluko phakathi kwawo.
Okokuqala, ake siqhathanise ukwakheka kweamabhethri e-alkalinenaleyo yamabhethri omile ajwayelekile. Amabhethri omile avamile ngokuvamile athatha isakhiwo se-monolithic, esinezinto ezihlukanisayo ezihlukanisa ama-electrode amabili. Nakuba lo mklamo ulula, ukusebenza kwebhethri nempilo yokuphila kuphansi kakhulu. Ngokuphambene, amabhethri e-alkaline asebenzisa ukwakheka kwamaseli amaningi ukuze athuthukise ukusebenza kwebhethri nempilo yokuphila. Lo mklamo uvumela amabhethri e-alkaline ukuthi asebenzise kangcono ukusabela kwamakhemikhali, anikeze ukuhlinzekwa kwamandla okuzinzile.
Okulandelayo, ake sibheke umehluko ekubunjweni kwamakhemikhali phakathi kwalokhu okubili. I-electrolyte yamabhethri omile ajwayelekile ngokuvamile i-alkaline semi-solid material, njenge-zinc chloride noma i-ammonium carbamate. Ngakolunye uhlangothi, amabhethri e-alkaline asebenzisa izinto ezine-alkaline njenge-potassium hydroxide noma i-potassium hydroxide njenge-electrolyte. Lo mehluko wenza i-electrolyte yamabhethri e-alkaline ibe nokuminyana kwamandla okuphezulu, ngakho-ke amandla amabhethri e-alkaline makhulu, ahlinzeka ngokuhlinzeka kwamandla okuzinzile.
Ngaphezu kwalokho, amabhethri e-alkaline nawo adlula amabhethri omile ajwayelekile ngokusebenza. Njengoba i-potassium hydroxide kumabhethri e-alkaline inguketshezi, ukumelana kwangaphakathi kuncane kakhulu, okukhiqiza izikhathi ezi-3-5 zamanje ngaphezu kwebhethri yesayizi efanayo. Lokhu kusho ukuthi amabhethri e-alkaline anganikeza amandla amakhulu ukuze ahlangabezane nezidingo zamadivayisi adinga amandla aphezulu. Ukwengeza, amabhethri e-alkaline awakhiqizi igesi ngesikhathi sokuphuma, futhi i-voltage izinzile. Ngakolunye uhlangothi, amabhethri omile avamile akhiqiza igesi ethile ngesikhathi sokuphuma, okubangela ukungazinzi kwamandla kagesi.
Mayelana nokuqina, amabhethri e-alkaline nawo anezinzuzo ezibalulekile. Njengoba i-zinc kumabhethri e-alkaline ibamba iqhaza ekuphenduleni njengezingcezwana ezinjengezinhlayiyana ezinendawo enkulu yokuxhumana ne-electrolyte, ikhiqiza amandla amanje amakhulu futhi ibe nempilo ende yesevisi. Kodwa-ke, amabhethri omile ajwayelekile anezinga elisheshayo lokubola kwamandla kanye nempilo yesevisi emfushane uma kuqhathaniswa. Ngakho-ke, ezinhlelweni zokusetshenziswa kwesikhathi eside noma zemvamisa ephezulu, amabhethri e-alkaline ayisinqumo esingcono.
Kafushane, amabhethri e-alkaline anokusebenza okuphezulu nempilo yesevisi ende uma kuqhathaniswa namabhethri omile ajwayelekile. Kungakhathaliseki ukuthi ngokomthamo, okukhiphayo kwamanje, ukuqina kwamandla kagesi, noma ukuqina, amabhethri e-alkaline abonisa izinzuzo ezibalulekile. Ngakho-ke, ekuphileni kwansuku zonke, kufanele sikhethe ngokukhethekile ukusebenzisa amabhethri e-alkaline ukuze sizuze ukuhlinzekwa kwamandla okuzinzile futhi okuzinzile.
