Iibhetri ze-alkaline luhlobo oluqhelekileyo lwebhetri ye-electrochemical esebenzisa ulwakhiwo lwebhetri ye-carbon-zinc apho i-potassium hydroxide isetyenziswa khona njenge-electrolyte. Iibhetri ze-alkaline zihlala zisetyenziswa kwizixhobo ezifuna umbane ozinzileyo ixesha elide kwaye ziyakwazi ukusebenza kumaqondo obushushu aphezulu naphantsi, njengabalawuli, ii-transceivers zerediyo, ii-flashlights, njl.
1. Umgaqo wokusebenza kweebhetri ze-alkaline
Ibhetri ye-alkaline yibhetri yeseli eyomileyo efutha i-ion equlathe i-zinc anode, i-manganese dioxide cathode kunye ne-potassium hydroxide electrolyte.
Kwibhetri ye-alkaline, i-potassium hydroxide electrolyte isabela ukuvelisa ii-ion ze-hydroxide kunye nee-ion ze-potassium. Xa ibhetri inikwe amandla, kwenzeka i-redox reaction phakathi kwe-anode kunye ne-cathode nto leyo ekhokelela ekudlulisweni kwetshaja. Ngokukodwa, xa i-Zn zinc matrix ifumana i-oxidation reaction, iya kukhupha ii-electron eziya kuthi emva koko zidlule kwisekethe yangaphandle zize zifikelele kwi-MnO2 cathode yebhetri. Apho, ezi electron ziya kuthatha inxaxheba kwi-three-electron redox reaction phakathi kwe-MnO2 kunye ne-H2O ekukhutshweni kweoksijini.
2. Iimpawu zeebhetri ze-Alkaline
Iibhetri ze-alkaline zineempawu ezilandelayo:
Ubuninzi bamandla aphezulu - bunokubonelela ngamandla azinzileyo ixesha elide
Ixesha elide lokugcinwa - lingagcinwa iminyaka emininzi kwimeko engasetyenziswayo
Uzinzo oluphezulu - lunokusebenza kwiindawo zobushushu obuphezulu nobushushu obuphantsi.
Izinga eliphantsi lokuzikhupha - akukho lahleko yamandla ngokuhamba kwexesha
Ikhuselekile kakhulu - akukho ngxaki zokuvuza
3. Amanyathelo okuzikhusela ekusebenziseni iibhetri ze-alkaline
Xa usebenzisa iibhetri ze-alkaline, qiniseka ukuba uqaphela la manqaku alandelayo:
- Musa ukuzixuba nezinye iintlobo zeebhetri ukuze uphephe iingxaki zombane omfutshane kunye nokuvuza.
- Musa ukuzibetha ngogonyamelo, ukuzityumza okanye ukuzama ukuziqhekeza okanye ukutshintsha iibhetri.
- Nceda ugcine ibhetri kwindawo eyomileyo nepholileyo xa uyigcina.
- Xa ibhetri iphelile, nceda uyitshintshe ngentsha ngexesha elifanelekileyo kwaye ungayilahli ibhetri esetyenzisiweyo.
