Akusiyo imfihlo ukuthi imithombo ephathekayo yogesi ekwazi ukuzimela ingaba yinto evamile futhi ishicilelwa. Emabhethri avamile, kokubili usawoti kanye ne-alkali, kanye ne-lithium, ukuphendula kwamakhemikhali akunakulungiswa, futhi kumaseli ebhethri kungenziwa isikhathi eside ngokuvuselelwa kwe-cyclic. Ngakho yiziphi amabhethri angakhokhiswa nokuthi angazihlukanisa kanjani komunye nomunye - kulesi sihloko.
Ngingazi kanjani ukuthi ngingakwazi ukushaja ibhethri?
Into yokuqala ehlukanisa ibhethri ebhethri evamile yilokho okubhalwe kukhombisa amandla emilliamperes ngehora (mAh). Ngokuvamile, umenzi ubeka ezincwadini ezinkulu, ngakho-ke akunakwenzeka ukuba ungaboni. Okukhudlwana le nombolo, isikhathi eside ibhethri sizohlala.
Amabhethri angashajwa anegama elivame ibhethri - elisha kabusha, elihumusha ngokuthi "lilayishwa kabusha". Uma umthengi ebona ukubhaliswa akuvuseleli, kusho ukuthi idivayisi ayikwazi ukuvuselelwa.
Umehluko wesithathu yintengo. Amabhethri ayi-oda eliphakeme kakhulu kunamabhethri avamile, futhi amanani akhiwa ngamandla abo futhi avuselela imijikelezo. Noma kunjalo, amandla aphezulu ahluke kakhulu kumabhethri ajwayelekile, kodwa awukwazi ukuwafaka kabusha. Ungakwazi ukuhlukanisa lezi zithwala zamandla ngokubhalwe ukuthi "Lithium" ikhona kuwo.
I-voltage yamabhethri avamile yi-1.6 V, kanti amandla ebhethri ngu-1.2 V. Ukuba nensimbi ekhethekile yokulinganisa - i-multimeter noma i-voltmeter - ungalinganisa lesi sibalo bese uqonda ukuthi yini ezandleni zakho.
Ibhethri evamile izozibonakalisa ohlelweni lokusebenza: njengoba seliyekile ukusebenza kudivayisi enamandla kakhulu, ingafakwa kwenye idivayisi enezimfuneko ezimbalwa zamandla futhi ngaleyo ndlela ikhulise impilo yayo. Amabhethri asebenza isikhathi eside, akhululwa kancane kancane, futhi asungulwe yonke imithombo, uzophinde alungele ukusebenza emva kokuvuselela.
Labo abazibuza ukuthi kungenzeka yini ukukhokhisa amabhethri avamile, kufanele kubone ukuthi azihloselwe lokhu. Ngcono kakhulu, kuzophela ekukhanyeni kwe-zilch, nasekuqhumeni okukhulu, nayo yonke imiphumela elandelayo. Amabhethri anoma yiluphi uhlobo lwe-electrolyte angakhokhiswa futhi lokhu kuyoba impendulo yombuzo walabo ababuza ukuthi kungenzeka yini ukuthelela amabhethri athile ahambisana nawo. Kodwa-ke, umcabango wabakhi bendabuko awunayo futhi namuhla abaningi bathole indlela yokukhokha amabhethri avamile. Ngakho-ke, unentshisekelo, kungakhathaliseki ukuthi kungenzeka yini ukukhokhisa amabhethri evamile alkaline, kufanelekile ukuphendula ukuthi kungenzeka. Ukuze wenze lokhu, eshaja ngamabhethri angu-4 udinga ukubeka amabhethri angu-3 ahleliwe, futhi ngakwesokudla ibhetri elilodwa. Emva kwemizuzu engu-5-10 bayobe sebekulungele ukusebenza.
