Lub pob roj teeb qhuav, kev paub txog kev tshawb fawb zoo nkauj nrog manganese dioxes, uas nqa tawm cov hluav taws xob tsis zoo, uas nqa tawm redebe cov tshuaj tiv thaiv los tsim tam sim no. Cov roj teeb qhuav qhuav yog cov roj teeb uas feem ntau hauv lub neej txhua hnub thiab yog cov qauv thoob ntiaj teb, nrog cov qauv thoob ntiaj teb thiab cov qauv ntawm ib leeg.
Cov roj teeb qhuav qhuav muaj cov thev naus laus zis tshuab, kev ua tau ruaj khov, kev nyab xeeb, kev ntseeg tau, yooj yim siv thiab ntau cov kev siv. Hauv lub neej txhua hnub, cov qauv ib txwm ntawm Zinc-Manganese cov roj teeb tsis muaj. 7 (AAA hom roj teeb), No. 5 (AA hom roj teeb) thiab lwm yam roj teeb. Although scientists have also been trying to explore a more inexpensive and cost-effective primary battery, but so far there is no sign of success, it can be expected that at present, and even in the longer term, there is no better cost-effective battery to replace zinc-manganese batteries.
Raws li cov qauv sib txawv thiab cov txheej txheem, Zinc-Manganese cov roj teeb feem ntau muab faib ua cov roj teeb carbon monomium thiab cov roj teeb alkaline. Ntawm lawv, roj teeb alkaline yog tsim los ntawm cov roj teeb carbon, thiab cov electrolyte yog feem ntau yog cov poov tshuaj hydroxide. Alkaline roj teeb tau txais cov qauv electrode los ntawm cov khoom siv roj teeb roj teeb, thiab cov khoom siv hluav taws xob siab heev, thiab cov khoom siv hluav taws xob siab thiab cov khoom tsis zoo rau hluav taws xob yog tsuas yog zinc zoo.
Cov roj teeb alkaline tau ua kom zoo tshaj plaws ntawm Zinc Quav, cov khoom siv ua kom zoo, thiab lwm yam kev ua kom zoo dua, thiab lwm yam ntxiv, feem ntau yog cov roj teeb tsis zoo, tshwj xeeb tshaj yog cov kev tawm dag zog ntau tam sim no.
1. Tuam Tshoj Tus Roj Teeb Alkaline Export Xav Tau Tsav Ntau Lawm
Nyob rau hauv xyoo tsis ntev los no, nrog kev nce qib ntawm kev tsim kho roj teeb alkaline, raws li cov roj teeb txuas ntxiv, raws li cov roj teeb txuas ntxiv mus, 19.32 billion.
Hauv 2019, Tuam Tshoj Alkaline Zinc-Hanganese roj teeb nce mus rau 23.15 txhiab roj teeb ua ke nrog kev tsim kho roj teeb
2. Tuam Tshoj lub roj teeb alkaline export nthuav dav txuas ntxiv txhim kho
Raws li kev txheeb cais ntawm Tuam Tshoj Chemical thiab Lub Cev Kev Lag Luam Kev Lag Luam Kev Lag Luam, Tuam Tshoj lub roj teeb alkaline export ntim yog 11.057 nphom, nce 3.69% xyoo. 2020, Tuam Tshoj ib lub roj teeb alkaline export ntim yog 13.189 txhiab xyoo, nce 19.3% xyoo nyob rau xyoo.
Hais txog cov nyiaj xa tawm, raws li Tuam Tshoj Kev Lag Luam Kev Lag Luam thiab Lub Cev Hluav Taws Xob Hluav Taws Xob Qhia tau hais tias txij li 2014, Tuam Tshoj lub roj teeb alkaline export qhia tus qauv kev nce tag nrho. 2019, Tuam Tshoj lub roj teeb alkaline xa tawm rau $ 991 lab, nce 0.41% xyoo-nyob rau xyoo. 2020, Tuam Tshoj lub roj teeb alkaline xa tawm rau $ 1.191 nphom, nce 20.18% xyoo-nyob rau xyoo.
Los ntawm qhov pom ntawm lub hom phiaj ntawm Tuam Tshoj lub roj teeb alkaline export yog cov khoom siv roj teeb alkaline ua ke ntawm 6.832 lab rau 61.79 ntawm tag nrho cov kev xa tawm; Ua ke cov xa tawm ntawm $ 633 lab, suav rau 63.91% ntawm tag nrho cov kev xa tawm. Ntawm lawv, cov khoom lag luam nthuav dav ntawm cov roj teeb alkaline rau Tebchaws Meskas yog 1.962 lab, nrog tus nqi xa tawm ntawm 214 lab nyiaj daus las ntawm 214 lab daus las ntawm 21 xyoos, qeb duas peb, qeb duas.
3. Tuam Tshoj tus roj teeb alkaline hauv tsev tsis muaj zog tshaj qhov xa tawm
Ua ke nrog kev tsim khoom thiab ntshuam thiab export ntawm alkaline cov roj teeb, nws tau kwv yees li xyoo 2018, cov roj teeb pom kev zoo ntawm Alkaline Zinc-Mangleese cov roj teeb hauv lub tebchaws yog 12.09 lab. Kev Ua Ntej Ua ke nrog cov xwm txheej ntshuam thiab kev siv hluav taws xob thiab ntau ntau yam ntawm cov roj teeb
Cov ntaub ntawv saum toj no thiab kev tsom xam yog los ntawm foresight Industrial Industrial Institute kev kawm, ipenmenting Kev Kawm Txuj Ci, Ido nrhiav kev lag luam, kev sau ntawv tseem ceeb, thiab lwm yam.
