Lithium polymer roj teeb

lithium polymer roj teeb

Lithium-ion thiab lithium polymer roj teeb yog hom roj teeb uas muaj lithium ua cov khoom siv hluav taws xob. Li-ion roj teeb yog ib qho ntawm lub ntiaj teb cov xov tooj nrov tshaj plaws rau cov khoom siv hluav taws xob portable. Nyob rau hauv xyoo tsis ntev los no, loj loj zus tau tej cov hlwb tau spurred los ntawm kev thov rau plug-in electric tsheb thiab daim phiaj cia daim ntaub ntawv.

Cov roj teeb lithium-ion yog thawj cov roj teeb ua lag luam ua tiav ntawm txhua hom, ua rau lawv paub zoo. Lawv ua tus thawj coj ntawm lub lag luam khoom siv hluav taws xob vim tias lawv lub zog siab ceev, them ceev ceev thiab tsis muaj kev nco. Lub siab tam sim no tso zis ntawm lithium-ion raws li cov cuab yeej hluav taws xob ua rau lawv zoo tagnrho rau kev siv xws li woodworking, drilling thiab sib tsoo.

Cov roj teeb lithium polymer yog nyias, cov roj teeb tiaj tiaj uas muaj cov khoom sib txuas ntawm cov anode thiab cathode sib cais los ntawm cov khoom siv hluav taws xob polymer. Lub polymer electrolyte tuaj yeem ntxiv qhov yooj yim rau lub roj teeb, ua kom yooj yim ntim rau hauv qhov chaw me dua lithium-ion roj teeb.

Feem ntau hom ntawm lithium polymer roj teeb siv lithium ion anode thiab cov organic electrolyte, nrog rau qhov tsis zoo electrode ua los ntawm carbon thiab anode composite cathode khoom. Qhov no yog lub npe hu ua lithium polymer thawj cell.

Feem ntau hom ntawm lithium-ion roj teeb raws li siv lithium hlau anode, carbon dub cathode thiab cov organic electrolyte. Cov electrolyte yog ib qho kev daws ntawm cov kuab tshuaj organic, lithium ntsev thiab polyvinylidene fluoride. Lub anode yuav tsim los ntawm carbon los yog graphite, lub cathode feem ntau yog tsim los ntawm manganese dioxide.

Ob hom roj teeb ua haujlwm tau zoo ntawm qhov kub thiab txias tab sis lithium polymer roj teeb muaj qhov siab dua nominal voltage dua li qhov loj ntawm lithium-ion cell. Qhov no tso cai rau cov ntim me me thiab cov roj teeb hnyav dua rau cov khoom siv hluav taws xob portable siv 3.3 volts lossis tsawg dua, xws li ntau eReaders thiab smartphones.

Lub nominal voltage rau lithium-ion hlwb yog 3.6 volts, whereas lithium polymer roj teeb muaj nyob rau ntawm 1.5 V mus txog rau 20 V. Lithium-ion raws li roj teeb muaj lub zog ntau dua li qub lithium polymer roj teeb vim lawv cov anode me me thiab kev sib txuas ntau dua hauv cov anode.
