Lub ntiaj teb niaj hnub no muaj cov khoom siv hluav taws xob: los ntawm cov khoom siv me tshaj plaws hauv daim ntawv ntawm lub teeb nyem mus rau cov khoom loj hauv kev tsim khoom. Tab sis tsis yog txhua tus ntawm lawv ua haujlwm los ntawm lub zog ncaj qha, ntau ntawm lawv ua haujlwm ua tsaug rau cov khoom siv txawb, piv txwv li, xws li roj teeb alkaline.

Ntawm lawv, muaj ob hom tseem ceeb: hlau-nickel thiab cadmium-nickel. Qhov loj rau cov phiaj zoo ntawm ob hom roj teeb yog npib tsib xee oxide hydrate, rau qhov tsis zoo nws yog kev sib xyaw ntawm cadmium thiab hlau. Them cov roj teeb alkaline pib nrog tam sim no ntawm 1.5 volts, tom qab ntawd qhov hluav taws xob maj mam nce mus rau 1.8 volts. Nws yuav tsum tau muab sau tseg tias thaum kub poob, lub roj teeb muaj peev xwm txo los ntawm 0.5% ib degree.

Cia peb qhia txog qhov zoo uas cov roj teeb alkaline muaj tshaj cov roj lead-acid:

1. Tsis tshua muaj thiab tsis tshua muaj hlau lead tsis siv rau hauv lawv cov khoom siv.

2. Ua kom muaj zog txhua yam thiab kev ua siab ntev (tsis ntshai ntawm kev poob siab, co thiab luv circuits).

3. alkalineCov roj teeb siv tau ntev dua txawm tias thaum tsis ua haujlwm ntev.

4. Cov roj teeb tso pa tawm tsawg dua thiab cov pa phem.

5. Muab piv rau cov hmoov txhuas, lawv lub teeb heev.

6. Tsawg xav tau kev saib xyuas.

Alkaline roj teeb kuj muaj qhov tsis zoo:

1. EMF tsawg dua li cov kua qaub lead.

2. Kev ua tau zoo yog kwv yees li 40 - 50% qis dua.

3. Tus nqi ntau dua.

Hnub no, cov roj teeb alkaline tsuas yog siv hauv cov tshuab uas ua haujlwm nyob rau hauv kev ua haujlwm hnyav, lossis qhov yuav tsum tau ua haujlwm ntev thiab kev ntseeg siab (tsim thiab kev ua liaj ua teb machinery). Wb tham txog ob hom roj teeb tseem ceeb, uas yog nickel-cadmium thiab nickel-hlau hydride.

thawj lub roj teeb nickel-cadmium pib tsim xyoo 1950. Txij thaum ntawd los, lawv tau tshawb nrhiav tag nrho. Kev txhim kho ntawm cov thev naus laus zis tshiab tau ua rau nws muaj peev xwm ua kom lawv cov yam ntxwv zoo. Lub peev xwm ntawm cov roj teeb no tau siv niaj hnub no hauv ntau yam khoom siv (txawm tias nyob hauv qhov chaw) thiab cov cuab yeej tshwj xeeb. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov khoom lag luam hauv tsev ntawm hom no txawv ntawm cov neeg txawv teb chaws, vim tias txawv teb chaws lawv raug tsim tawm hauv cov khoom sib cais rau cov neeg siv khoom thov.

Nickel-hlau-hydride alkaline roj teeb tsis tshua nyiam vim qhov tseeb tias ntau xyoo dhau los lawv tau hloov pauv ntau los ntawm cov qauv nickel-cadmium. Kev tshawb fawb tsis ntev los no tau txhim kho zoo heevyam ntxwv. Vim muaj kev xav txog ib puag ncig, kev kawm ntawm cov roj teeb cadmium tau maj mam poob qis, thiab cov roj teeb hlau hydride nyiam dua, tab sis, hmoov tsis zoo, lawv cov koob npe tseem tsis tau nce siab.

Thaum kawg, kuv xav kom nco ntsoov tias qhov ua tau zoo, thiab qhov tseem ceeb tshaj plaws, lub sijhawm ua haujlwm, feem ntau yog nyob ntawm lub chargers, uas yuav tsum muaj kev tswj kom meej meej ntawm cov txheej txheem them nqi raws li ntau yam xwm txheej. Yog li ntawd, thaum yuav cov roj teeb alkaline, ua tib zoo kawm lawv cov yam ntxwv thiab lawv cov kev ua haujlwm.
