Lub roj teeb lub pob khawm yog dab tsi?

Muaj ntau hom roj teeb. Raws li ib qho ntawm cov kev faib roj teeb, lub pob roj teeb tau paub los ntawm nws lub npe. Nws yog lub roj teeb zoo li lub pob, yog li nws tseem hu ua pob roj teeb.

Khawm ntawm tes

Cov roj teeb pob txheem muaj cov tshuaj lom neeg hauv qab no: lithium-ion, carbon, alkaline, zinc-silver oxide, zinc-air, lithium-manganese dioxide, nickel-cadmium rechargeable roj teeb, nickel-hlau hydride rechargeable khawm roj teeb, thiab lwm yam. diameters, thicknesses, thiab siv.

Lub ntsiab tivthaiv ntawm lithium-ion khawm roj teeb yog lithium-ion, uas yog 3.6V roj teeb rov qab. Nws raug them thiab tawm los ntawm lithium-ion txav, thiab lithium-ion txav ntawm qhov zoo electrode thiab qhov tsis zoo electrode ua haujlwm. Thaum lub sijhawm teeb tsa thiab tso tawm, Li intercalates thiab deintercalates rov qab los ntawm ob lub electrodes: thaum them nyiaj, Li deintercalates los ntawm qhov zoo electrode thiab intercalates rau hauv qhov tsis zoo electrode los ntawm electrolyte; vice versa thaum tso tawm. Lawv feem ntau siv rau ntawm TWS headset roj teeb thiab ntau yam khoom siv ntse ntse.

Lithium-manganese dioxide khawm roj teeb yog qhov peb feem ntau hu ua lithium manganese roj teeb. 3V lithium manganese roj teeb tau dav siv thiab feem ntau cim nrog CR

Khawm roj teeb

Cov roj teeb carbon thiab alkaline roj teeb yog ob lub roj teeb qhuav. Lawv feem ntau pom nyob rau hauv No.5 thiab No.7 roj teeb. Kuv feem ntau siv cov pa roj carbon dub rau hauv cov roj carbon monoxide ua chalk rau kev sau ntawv thaum kuv tseem hluas. Cov roj teeb carbon thiab alkaline roj teeb zoo sib xws hauv kev siv. Qhov sib txawv tseem ceeb tshaj plaws yog tias lawv muaj cov khoom siv sib txawv. Piv nrog rau cov roj teeb carbon, lawv pheej yig dua, tab sis vim tias lawv muaj cov hlau hnyav, lawv tsis tsim nyog rau kev tiv thaiv ib puag ncig, thaum cov roj teeb hauv ib puag ncig alkaline muaj mercury. Tus nqi tuaj yeem ncav cuag 0%, yog li nws yog qhov zoo dua los siv cov roj teeb alkaline yog tias peb yuav tsum siv lawv. Lawv kuj muaj lwm lub npe hu ua zinc-manganese roj teeb. Peb nquag siv 1.5V AG series roj teeb yog alkaline zinc-manganese khawm roj teeb; tus qauv yog sawv cev los ntawm LR, uas feem ntau yog siv hauv cov watches, cov khoom siv mloog pob ntseg, thiab lwm yam khoom siv.

Qhov loj ntawm zinc-silver oxide khawm roj teeb thiab AG roj teeb tsis txawv ntau. Lawv yog ob qho tib si 1.5V roj teeb, tab sis cov khoom siv ntxiv. Silver oxide yog siv los ua cov khoom siv hluav taws xob zoo, thiab zinc yog siv los ua qhov tsis zoo electrode (qhov zoo thiab qhov tsis zoo yog txiav txim siab raws li cov hlau ua haujlwm Pole) - alkaline roj teeb rau cov khoom.

Zinc-air khawm roj teeb txawv ntawm lwm cov roj teeb pob hauv qhov uas nws muaj lub qhov me me hauv qhov zoo casing uas tau qhib tsuas yog thaum siv. Nws cov khoom yog ua los ntawm oxygen raws li qhov zoo electrode active khoom thiab zinc raws li qhov tsis zoo electrode.

Nickel-cadmium rechargeable khawm-hom roj teeb tsis tshua pom hauv khw tam sim no, thiab lawv muaj cadmium, uas ua rau muaj kuab paug ib puag ncig.

Lub nickel-hlau hydride khawm roj teeb kuj yog 1.2V rechargeable. Nws yog tsim los ntawm cov khoom siv nquag NiO electrode thiab hlau hydride, thiab nws cov kev ua tau zoo heev.

Lub roj teeb lub pob khawm yog dab tsi? Koj puas paub tom qab nyeem tsab xov xwm no? Lub pob roj teeb tsuas yog sawv cev rau cov cua daj cua dub cov duab, thiab ntau yam kev ua tau zoo thiab qhov zoo tseem yuav tsum tau soj ntsuam thiab xyuas ib qho los ntawm ib qho.
