Amabhethri ane-alikhali futhi inzuzo yabo

Ezweni lanamuhla ligcwele electronics: kusuka kudivayisi kulencane ngesimo flashlight empahleni omkhulu emsebenzini. Kodwa akuwona wonke ukusebenza ngumthombo oqondile yamandla, abaningi babo tisebenta ngokusebenzisa kumadivayisi eselula, isibonelo, njenge amabhethri ane-alikhali.

Phakathi kwabo kukhona izinhlobo ezimbili eziyinhloko: i-iron-nickel kanye nickel-cadmium. IMisa ibhetri amapuleti omuhle kokubili zinhlobo kuyinto hydrate nickel oxide ngokuba omubi kuba inhlanganisela cadmium nensimbi. Elishajekayo ane-alikhali ibhethri iqala kokunikeza zamanje 1.5 e., Ngemva kwalokho voltage ukwanda kancane kancane ukuba 1.8 volts. Kufanele kuqashelwe ukuthi uma izinga lokushisa lehliselwa umthamo webhethri kuyehla ngo-0.5% kuyo yonke degree.

Ake agcizelele izinzuzo ukuthi ane-alikhali amabhethri ukuhola-acid:

1. womshini yabo ungayisebenzisi phambili ezingavamile futhi zimbalwa.

2. okuthuthukisiwe amandla mechanical ubunzima (ningesabi ashaye, kunyakaze, futhi short-izifunda).

3. ane-alikhali amabhethri isikhathi eside, ngisho nangemva eside isikhathi lutho.

4. evala futhi amagesi amabhethri eziyingozi ukukhiqiza kancane.

5. Uma kuqhathaniswa umthofu, zingabantu bekulula.

6. Ngaphansi lifuna ukuhamba.

amabhethri ane-alikhali futhi babe nemibi:

1. EMF angaphansi kwezinga lomthofu - acid.

2. ukusebenza ngekhono ngezansi mayelana 40 - 50%.

3. Izindleko iphezulu kakhulu.

Namuhla, amabhethri ane-alikhali zisetshenziselwa kuphela imishini okuyinto umsebenzi wenziwa ngaphansi kwezimo ezimbi, noma lapho ukuqina ezidingekayo nokwethembeka (ukwakhiwa kanye imishini yezolimo). Ake sixoxe izinhlobo ezimbili eziyinhloko amabhethri, okungukuthi nickel-cadmium kanye hydride nickel-metal.

Eyokuqala nickel-cadmium amabhethri zavezwa ngo-1950. Kusukela ngaleso sikhathi, baye kwehlwaywe. Ukuthuthukiswa ezintsha zokukhiqiza technologies kungavunyelwa ngezikhathi ukwandisa ukusebenza kwabo. Ikghono lama amabhethri wenziwa ngenkuthalo esetshenziswa hardware ezahlukene (ngisho isikhala) kanye nemishini ekhethekile. Kubalulekile ukuqaphela ukuthi production ezifuywayo yalolu hlobo iyahluka kwenye angaphandle analogue, t. Ukuze. Ukukhiqizwa yabo kwelinye izwe amaqoqwana ahlukene izidingo ezithile amakhasimende.

Nickel hydride metal ane-alikhali amabhethri mancane ethandwa ngenxa yokuthi kule minyaka eyishumi edlule zakhuza ecindezelwe amasampula nickel-cadmium. Ucwaningo lwamuva luye avunyelwe ukwenza ngcono ukusebenza kwabo. Ngenxa yezakhi yokuphepha kwezemvelo cwaningo cadmium ibhethri kancane kancane, futhi kubonelelwa kakhulu ama-hydride metal, kodwa ngeshwa, udumo lwawo ayizange kwashesha.

Ekupheleni-ke kufanele kuqashelwe ukuthi ukusebenza kahle, futhi okubaluleke kakhulu, isikhathi wokusebenza ku engaphansi oyinhloko amadivaysi ukunikeza control eqondile yenqubo ukushaja ngaphansi kwezimo ezihlukahlukene. Ngakho-ke, ukuthenga amabhethri ane-alikhali, bahlolisise izici kanye nezimo zokusebenzela zabo.
