Egcwalisekayo iibhetri finger - ukukhetha njani?

Ingaba unayo nayiphi na wotshi? Okanye layita? Okanye, ukuba kude TV? Zonke ezi zinto zibe umthombo omnye kuba amandla abo - oko zitshajwe iibhetri umnwe. Akukho lula ukuya kuthenga ibhetri ekunene. Ungakhetha kuye, Kakade ke, imbonakalo yakhe, ngegama, ixabiso, okanye athathe efana naleyo ngaphambili kwi sixhobo. Noko ke, izixhobo zokusebenza ezikumgangatho ezifana neebhetri zitshajwe umnwe, kufuneka wazi futhi uqonda umahluko ebonakalayo uhlobo omnye komnye. Ngoko ke ukhetha njani na?

Okokuqala, simele siqonde ukuba ityuwa egcwalisekayo iibhetri umnwe unokuba kwamandla ezahlukeneyo kwaye abe nobukhulu obahlukeneyo. Uyilo esilula zabo nezakhiwo: kwelinye icala le anode, kwelinye - a cathode kunye electrolyte ibekwe phakathi kwabo.

Wona ngokumila zezindlu ukuba kwisixhobo ezifana neebhetri umunwe ukhethe nje kwenzeka. Isilinda imxinwa kunye namandla efanayo inomlingani ephakamileyo melelo wokuzibhubhisa ubushushu edada. Leyibhelisha ezi zixhobo phantsi kwemithetho unobumba R kunye nenombolo (umz, R11).

Indlela zokukhethwa izixhobo ezifana neebhetri penlight ukuba iimeko zomsebenzi. Oku kunokuba umthwalo omkhulu (kwi yangoku 0.2 amps), eliphakathi (0.1 amps) kunye ezincinci (ngaphantsi kwe 0,01 amps). imithwalo enzima kunokubonwa xa usebenzisa iibhetri isibane, iikhamera, soxinzelelo lwegazi kunye nabadlali. Avareji iyasebenza zokudlala abantwana. uphawu umthwalo omncinane zewotshi. Ngaphandle kwamathandabuzo, kuzo zonke ezi meko, ibhetri izakuziphatha ngendlela eyahlukileyo.

Kuyimfuneko ukuba ukukhumbula impembelelo ngqo lokusingqongileyo kwintsebenzo isixhobo ezifana zitshajwe iibhetri umnwe. Kwiqondo lobushushu electrolyte ndiwuthobile conductivity liyancipha, kwaye unciphisa amandla umthombo. Eqhelekileyo lihamba lobushushu ibhetri ukusuka degrees kwiqanda ukuya mahlanu. Ibhetri kakhulu kakhulu akhutshelwe ekuqaleni zokugcina. Ngoko ke kufuneka ukuba bathenge iibhetri ebusika phandle.

Iibhetri lungahlulwa-hlulwa ibe lithium, ialakalin kunye saline (zahluke njani bubunjani electrolyte sabo).

Iziqalelo ezingundoqo ethile ityuwa ithe kuchazwe wokwehla ombane yokusebenza ngexesha nokukhutshwa. Ukusebenza umthamo i battery iya kuba ngaphezu kwi imithwalo eliphakathi ophezulu kunye nemeko uveza. Wena uyakwazi ukubona ukuba xa ethe ngokupheleleyo kuya kumpompoza electrolyte ibhetri kulo. Olu hlobo penlight neebhetri yeyona ixhaphake kakhulu ngenxa cheapness yayo.

neebhetri awana eqinile ngakumbi. Zisebenza kakuhle kumaqondo obushushu asezantsi kwaye kungcono nokugcina iimpawu zazo e Postojna. Ngokwendalo, ixabiso labo liya kuba ngaphezulu kakhulu kunokuba yetyuwa.

Kwaye ekugqibeleni, kufuneka athi malunga neebhetri Lithium. Bathe ezimalini (ezibizayo kwealkali, kunye netyuwa), kodwa kukho iimpawu amandla amakhulu, phezulu ombane yokusebenza, uzinzo, uluhlu olubanzi imisinga obhobhozayo kunye amaqondo esebenza, ubomi obude kunye nokugcinwa.
