Ibhetri ye-alkalineyahlulwe yaba ziintlobo ezimbini zeibhetri ye-alkaline etshajwayokunye nebhetri ye-alkaline engaphinde itshajwe, njengangaphambili, ibhetri ye-alkaline eyomileyo yethotshi yakudala ayiphinde itshajwe, kodwa ngoku ngenxa yotshintsho lwemfuno yesicelo semarike, ngoku ibhetri ye-alkaline inokutshajwa, kodwa apha kukho iingxaki ezininzi zobugcisa, ezinje ngokutshaja okukhulu kwamandla, ibhetri ye-alkaline inokutshajwa?

Iibhetri ze-alkaline zingatshajwa amaxesha angama-20 ngaphantsi kwe-0.1C, kodwa oku kwahlukile kwinkqubo yokutshaja kwakhona kweebhetri zesibini. Kwiimeko eziqhelekileyo, zinokutshajwa kuphela ngokukhupha okungaphelelanga kwaye azinakutshajwa ngokukhupha okunzulu okufanayo nebhetri yokwenyani etshajwayo.

Ukutshaja ibhetri ye-alkaline yinxalenye nje yetshaja, ebizwa ngokuba kukuvuselelwa, ingcamango yokuvuselelwa ichaza ngakumbi iimpawu zokutshaja ibhetri ye-alkaline: ibhetri ye-alkaline inokutshaja? Ewe, ngaphandle kokuba kukutshaja okuvuselelayo, ngokuchaseneyo nokutshaja okwenyani kweebhetri ezinokutshajwa kwakhona.

Ukuthintelwa kokutshaja nokukhupha ibhetri ye-alkaline kunye nobomi obufutshane bomjikelo webhetri kwenza kube nzima ukuhlaziya ibhetri ye-alkaline. Ukuze kuqinisekiswe ukuhlaziywa ngempumelelo kweebhetri ze-alkaline, le miqathango ilandelayo kufuneka ifezekiswe.

Amanyathelo/Iindlela

1. Phantsi kwesimo somlinganiselo ophakathi wokukhupha, umthamo wokuqala webhetri uya kukhutshwa ukuya kuthi ga kwi-30%, kwaye ukukhutshwa akufuneki kube ngaphantsi kwe-0.8V, ukuze ukuvuselelwa kube nokwenzeka. Xa umthamo wokukhupha udlula i-30%, ubukho be-manganese dioxide buthintela ukuvuselelwa okungakumbi. Umthamo we-30% kunye nombane wokukhupha we-0.8V kufuneka kusetyenziswe izixhobo ezifanelekileyo, kodwa uninzi lwabathengi abanazo ezi zixhobo. Ngaba ibhetri ye-alkaline ingatshajwa kwakhona kule meko kubathengi abaninzi abaqhelekileyo? Asingombandela wezoqoqosho, ngumbuzo weemeko.

2, umsebenzisi angathenga itshaja ekhethekileyo ukuze ayivuselele. Ukuba usebenzisa enye itshaja, ngaba iibhetri ze-alkaline zingatshajwa? Iingozi zokhuseleko zikhulu kakhulu, phantsi kweemeko eziqhelekileyo, itshaja yebhetri ye-nickel cadmium, itshaja ye-nickel metal hydride ayinakusetyenziselwa ukutshaja ibhetri ye-alkali manganese, kuba umsinga wokutshaja itshaja uphezulu kakhulu, unokukhokelela kwigesi yangaphakathi yebhetri, ukuba igesi ephuma kwivalvu yokhuseleko, iya kuvuza. Ngaphezu koko, ukuba ivalvu yokhuseleko ayiluncedo, kunokubakho nokuqhuma. Oku kunqabile ukuba isikhunta singasebenzi kakuhle, kodwa kunokwenzeka, ingakumbi ukuba ibhetri ayisetyenziswanga ngokuchanekileyo.

3, ixesha lokuvuselelwa (malunga neeyure ezili-12) lingaphaya kwexesha lokukhululwa (malunga neyure e-1).

4. Umthamo webhetri uya kuncitshiswa uye kwi-50% yomthamo wokuqala emva kwemijikelo engama-20.

5, izixhobo ezikhethekileyo zokunxibelelana kweebhetri ezingaphezu kwezintathu, ukuba amandla ebhetri awahambelani, kuya kubakho ezinye iingxaki emva kokuvuselelwa, okunokukhokelela kwi-voltage yebhetri engalunganga ukuba ibhetri evuselelayo kwaye ingasetyenziswanga kunye ibhetri iya kuba yingozi ngakumbi. Ukubuyela umva kwebhetri kubangela ukuba i-hydrogen yenziwe ngaphakathi kwebhetri, nto leyo enokubangela uxinzelelo oluphezulu, ukuvuza kwanokuqhuma. Ngaba iibhetri ze-alkaline zingatshajwa kwakhona ngaphandle kokuba zonke ezintathu zivumelane kakuhle? Ngokucacileyo akuyomfuneko.

Ibhetri ye-alkaline zinc-manganese etshajwayo Ibhetri ye-alkaline zinc-manganese ephuculweyo, okanye i-RAM, enokutshajwa kwakhona ukuze isetyenziswe kwakhona. Ulwakhiwo kunye nenkqubo yokwenziwa kolu hlobo lwebhetri ngokusisiseko ziyafana naleyo yebhetri ye-alkaline zinc-manganese.

Ukuze ibhetri ikwazi ukutshajwa kwakhona, iphuculwe ngokusekelwe kwibhetri ye-alkaline zinc-manganese: (1) Phucula isakhiwo se-electrode esihle, uphucule amandla eringi ye-electrode entle okanye wongeze izongezo ezifana nezincamathelisi ukuthintela ukudumba kwe-electrode entle ngexesha lokutshaja nokukhupha; ② ukubuyiselwa kwe-manganese dioxide kunokuphuculwa ngokufaka i-doping entle; ③ Lawula ubungakanani be-zinc kwi-electrode engalunganga, kwaye ulawulo lwe-manganese dioxide lunokukhutshwa kuphela nge-electron enye; (4) Umaleko wokuzahlula uyaphuculwa ukuthintela i-zinc dendrites ukuba ingangeni kumaleko wokuzahlula xa ibhetri itshajwa.

Ngamafutshane, ibhetri ye-alkaline inokutshajwa, okanye ukubona imiyalelo yokuvelisa ibhetri ye-alkaline, ukuba imiyalelo ithi inokutshajwa, inokutshajwa, ukuba ayitshajwa, ayitshajwa.
