Ziziphi iibhetri zeAlkaline?

Iibhetri zealkalineluhlobo lwebhetri elahlwayo esebenzisa ialkaline electrolyte ye potassium hydroxide. Zidla ngokusetyenziswa kuluhlu olubanzi lwezixhobo, ezifana neremote control, iitotshi, izinto zokudlala, kunye nezinye izixhobo. Iibhetri zealkaline ziyaziwa ngobomi bazo obude beshelufu kunye nokukwazi ukubonelela ngemveliso yamandla engaguqukiyo ekuhambeni kwexesha. Ngokuqhelekileyo zibhalwe ngekhowudi yeleta efana ne-AA, AAA, C, okanye D, ebonisa ubungakanani kunye nohlobo lwebhetri.

Ngawaphi amalungu eebhetri zealkaline?

Iibhetri zealkaline zineenxalenye ezininzi ezibalulekileyo, kuquka:

I-Cathode: I-cathode, eyaziwa ngokuba sisiphelo esihle sebhetri, ngokuqhelekileyo yenziwe nge-manganese dioxide kwaye isebenza njengendawo yeekhemikhali zebhetri.

I-Anode: I-anode, okanye isiphelo esibi sebhetri, ngokuqhelekileyo iqulunqwe yi-zinc powder kwaye isebenza njengomthombo we-electron ngexesha lokukhutshwa kwebhetri.

I-Electrolyte: I-electrolyte kwiibhetri ze-alkaline isisombululo se-potassium hydroxide evumela ukuhanjiswa kwee-ion phakathi kwe-cathode kunye ne-anode, eyenza ukuhamba kombane.

Isahluli: Isahluli sisixhobo esahlula ngokwasemzimbeni i-cathode kunye ne-anode ngaphakathi kwebhetri ngelixa uvumela i-ion ukuba idlule ukugcina ukusebenza kwebhetri.

Icasing: Icasing yangaphandle yebhetri yealkaline yenziwe ngentsimbi okanye iplastiki kwaye isebenza ngokuqulatha nokukhusela amalungu angaphakathi ebhetri.

Itheminali: Iitheminali zebhetri ziindawo zoqhagamshelwano ezivumayo nezingalunganga ezivumela ukuba ibhetri iqhagamshelwe kwisixhobo, ukugqibezela isekethi kunye nokuvula ukuhamba kombane.
Yeyiphi i-Chemical Reaction eyenzeka kwiibhetri ze-alkaline xa zikhutshiwe

Kwiibhetri zealkaline, ezi ntshukumo zilandelayo zeekhemikhali zenzeka xa ibhetri ikhutshwa:

Kwi-cathode (isiphelo esihle):
MnO2 + H2O + e- → MnOOH + OH-

Kwi-anode (isiphelo esibi):
Zn + 2OH- → Zn(OH)2 + 2e-

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

Ngamagama alula, ngexesha lokukhutshwa, i-zinc kwi-anode iphendula kunye ne-hydroxide ions (OH-) kwi-electrolyte ukwenza i-zinc hydroxide (Zn (OH) 2) kunye nokukhulula ii-electron. Ezi electron zihamba ngesiphaluka sangaphandle kwi-cathode, apho i-manganese dioxide (MnO2) isabela ngamanzi kunye nee-electron zenze i-manganese hydroxide (MnOOH) kunye ne-hydroxide ions. Ukuhamba kwee-electron kwisekethe yangaphandle kudala amandla ombane anokuthi anike amandla isixhobo.
Ungazi njani ukuba iibhetri zealkaline zomboneleli wakho zisemgangathweni olungileyo

Ukuqinisekisa ukuba eyakhoiibhetri zealkaline zomthengisizikumgangatho olungileyo, qwalasela le miba ilandelayo:

Isidima sebhrendi: Khetha iibhetri kwiimveliso ezisekiweyo nezihloniphekileyo ezaziwa ngokuvelisa iimveliso ezikumgangatho ophezulu.

Ukusebenza: Vavanya iibhetri kwizixhobo ezahlukeneyo ukuqinisekisa ukuba zibonelela ngemveliso yamandla engaguqukiyo nethembekileyo ekuhambeni kwexesha.

Ubomi obude: Jonga iibhetri ze-alkaline ezinobomi obude beshelufu ukuqinisekisa ukuba ziya kugcina intlawulo yazo ixesha elide xa zigcinwe kakuhle.

Umthamo: Jonga ubungakanani bomthamo weebhetri (ezidla ngokulinganiswa nge-mAh) ukuqinisekisa ukuba zinendawo yokugcina amandla eyaneleyo kwiimfuno zakho.

Ukuqina: Vavanya ukwakhiwa kweebhetri ukuqinisekisa ukuba zenziwe kakuhle kwaye zinokumelana nokusetyenziswa okuqhelekileyo ngaphandle kokuvuza okanye ukusilela kwangaphambi kwexesha.

Ukuthotyelwa kwemigangatho: Qinisekisa iibhetri zeUmthengisi weebhetri zealkalineukuhlangabezana nemigangatho yokhuseleko efanelekileyo kunye nomgangatho, njengeziqinisekiso ze-ISO okanye ukuthotyelwa kwemigaqo efana ne-RoHS (Umnyino lwezinto ezinobungozi).

Uphononongo lwabathengi: Qwalasela impendulo evela kwabanye abathengi okanye iingcali kushishino ukujonga umgangatho kunye nokuthembeka kweebhetri zealkaline zomboneleli.

Ngokuvavanya le miba kunye nokuqhuba uvavanyo olucokisekileyo kunye nophando, unokumisela ngcono ukuba iibhetri zealkaline zomboneleli wakho zikumgangatho olungileyo kwaye zilungele iimfuno zakho.
