Ibhethri le-alkalineihlukaniswe izinhlobo ezimbiliibhethri le-alkaline elishajekayokanye nebhethri le-alkaline elingaphinde lishajwe, njengangaphambili lapho sisebenzise khona i-flashlight yakudala, ibhethri elomile le-alkaline aliphinde lishajwe, kodwa manje ngenxa yoshintsho lwesidingo semakethe, manje sesinebhethri le-alkaline elingashajwa, kodwa lapha kunezinkinga eziningi zobuchwepheshe, njengokuthi, ukushaja okukhulu kwamandla kagesi, ibhethri le-alkaline lingashajwa?

Amabhethri e-alkaline angashajwa kabusha izikhathi ezingu-20 ngaphansi kuka-0.1C, kodwa lokhu kuhlukile enqubweni yokushaja kabusha yamabhethri esibili. Ngaphansi kwezimo ezivamile, angashajwa kuphela ngokukhipha ingxenye futhi awakwazi ukushajwa ngokukhipha okujulile okufanayo nebhethri langempela elingashajwa kabusha.

Ukushaja ibhethri le-alkaline kuyingxenye nje yeshaja, ngokuvamile okubizwa ngokuthi ukuvuselelwa, umqondo wokuvuselelwa uchaza kabanzi izici zokushaja ibhethri le-alkaline: ibhethri le-alkaline lingashaja? Yebo, ngaphandle kokuthi ukushaja okuvuselelayo, ngokungafani nokushaja kwangempela kwamabhethri ashajayo.

Ukulinganiselwa kokushaja okuvuselelayo kanye nokukhishwa kanye nokuphila komjikelezo omfushane webhethri le-alkaline kwenza kube nzima ukuvuselela ibhethri le-alkaline. Ukuze kuqinisekiswe ukuvuselelwa ngempumelelo kwamabhethri e-alkaline, lezi zimo ezilandelayo kumele zifezwe.

Izinyathelo/Izindlela

1. Ngaphansi kwesimo sesilinganiso sokukhishwa okumaphakathi, umthamo wokuqala webhethri uzokhishwa ufike ku-30%, futhi ukukhishwa akufanele kube ngaphansi kuka-0.8V, ukuze ukuvuselelwa kwenzeke. Lapho umthamo wokukhishwa udlula u-30%, ukuba khona kwe-manganese dioxide kuvimbela ukuvuselelwa okuqhubekayo. Umthamo ongu-30% kanye ne-voltage yokukhishwa engu-0.8V kudingeka kusetshenziswe imishini efanele, kodwa abathengi abaningi abanayo le mishini. Ingabe ibhethri le-alkaline lingashajwa kulesi simo kubathengi abaningi abavamile? Akuyona indaba yezomnotho, kungumbuzo wemibandela.

2, umsebenzisi angathenga ishaja ekhethekile ukuze ayivuselele. Uma usebenzisa enye ishaja, ingabe amabhethri e-alkaline angashajwa? Izingozi zokuphepha zikhulu kakhulu, ngaphansi kwezimo ezijwayelekile, ishaja yebhethri ye-nickel cadmium, ishaja yebhethri ye-nickel metal hydride ayikwazi ukusetshenziselwa ukushaja ibhethri le-alkali manganese, ngoba ugesi wokushaja ishaja uphezulu kakhulu, kungaholela kugesi wangaphakathi webhethri, uma igesi ephuma ku-valve yokuphepha, izovuza. Ngaphezu kwalokho, uma i-valve yokuphepha ingasebenzi, kungase kube nokuqhuma. Lokhu akuvamile ukwenzeka uma isikhunta singasebenzi kahle, kodwa kungenzeka, ikakhulukazi uma ibhethri lingasetshenziswanga kahle.

3, isikhathi sokuvuselelwa (cishe amahora ayi-12) singaphezu kwesikhathi sokukhishwa (cishe ihora eli-1).

4. Umthamo webhethri uzoncishiswa ube ngu-50% womthamo wokuqala ngemva kwemijikelezo engu-20.

5, imishini ekhethekile yokuxhumeka kwamabhethri angaphezu kwamathathu, uma umthamo webhethri ungaguquguquki, kuzoba nezinye izinkinga ngemva kokuvuselelwa, okungase kuholele ku-voltage yebhethri engemihle uma ibhethri elivuselelayo futhi lingasebenzisi ibhethri ndawonye lizoba yingozi kakhulu. Ukuguqulwa kwebhethri kubangela ukwakheka kwe-hydrogen ngaphakathi kwebhethri, okungase kubangele ukucindezela okuphezulu, ukuvuza ngisho nokuqhuma. Ingabe amabhethri e-alkaline angashajwa kabusha ngaphandle kokuba womathathu avumelane kahle? Ngokusobala akudingeki.

Ibhethri le-alkaline zinc-manganese elingaphinde lishajwe Ibhethri le-alkaline zinc-manganese elithuthukisiwe, noma i-RAM, elingaphinde lishajwe ukuze lisetshenziswe kabusha. Isakhiwo kanye nenqubo yokukhiqiza yalolu hlobo lwebhethri ngokuyisisekelo ifana nebhethri le-alkaline zinc-manganese.

Ukuze kufezwe ukushaja kabusha, ibhethri lithuthukisiwe ngokusekelwe kubhethri le-alkaline zinc-manganese: (1) Thuthukisa isakhiwo se-electrode esihle, uthuthukise amandla endandatho ye-electrode enhle noma wengeze izithasiselo ezifana nezinamathiselo ukuvimbela ukuvuvukala kwe-electrode enhle ngesikhathi sokushaja nokukhipha; ② ukuguqulwa kwe-manganese dioxide kungathuthukiswa ngokufaka i-doping enhle; ③ Lawula inani le-zinc ku-electrode engalungile, futhi ulawule i-manganese dioxide kungakhishwa kuphela nge-electron eyodwa; (4) Ingqimba yokuhlukaniswa iyathuthukiswa ukuvimbela ama-zinc dendrites ukuthi angangeni kungqimba yokuhlukaniswa lapho ibhethri lishajwa.

Ngamafuphi, ibhethri le-alkaline lingashajwa, noma ukubona ibhethri le-alkaline ngokwalo likhiqiza imiyalelo, uma imiyalelo ithi lingashajwa, lingashajwa, uma lingashajwa, lokho akushajwa.
