Kodi pali kusiyana kotani pakati pa mabatire a lithiamu ndi mabatire owuma? Chifukwa chiyani mabatire a foni yam'manja sagwiritsa ntchito mabatire owuma?

Kodi batire yowuma ndi chiyani, batire ya lithiamu, ndipo chifukwa chiyani mafoni a m'manja amagwiritsa ntchito mabatire a lithiamu m'malo mwa mabatire owuma?

1. Battery wouma

Mabatire owuma asandukanso mabatire a voltaic. Mabatire a Voltaic amapangidwa ndi magulu angapo a mbale zozungulira zomwe zimawonekera pawiri ndipo zimayikidwa motsatira dongosolo linalake. Pali mbale ziwiri zachitsulo pa mbale yozungulira, ndipo pali nsalu yotchinga pakati pa milingo yoyendetsera magetsi. Ntchito, batire youma imapangidwa molingana ndi mfundo iyi. Mu matope owuma muli chinthu chonga phala, ena mwa iwo ndi gelatin. Chifukwa chake, ma electrolyte ake amakhala ngati phala, ndipo Sangathe kubwezeretsanso batire yotayika yamtundu uwu wa batri ikatulutsidwa. Mphamvu ya electromotive ya zinc-manganese dry mortar ndi 1.5V, ndipo mabatire owuma osachepera angapo amafunikira kulipiritsa foni yam'manja.

Zomwe timawona nthawi zambiri ndi mabatire a 5 ndi 7. Mabatire a nambala 1 ndi nambala 2 sagwiritsidwa ntchito mochepera. Batire iyi imagwiritsidwa ntchito kwambiri pa mbewa zopanda zingwe, mawotchi a alamu, zoseweretsa zamagetsi, makompyuta, ndi mawayilesi. Nanfu Battery sangakhale wodziwika bwino; ndi kampani yotchuka ya batri ku Fujian.

2. Lithiamu batri

Njira yamkati ya batri ya lithiamu ndi njira yopanda madzi ya electrolyte, ndipo zinthu zovulaza za electrode zimapangidwa ndi lithiamu zitsulo kapena lithiamu alloy. Chifukwa chake, kusiyana pakati pa batri ndi batire yowuma ndikuti zomwe zimachitika mkati mwa batri ndizosiyana, ndipo mawonekedwe opangira ndi ena. Ikhoza kubwezeretsanso batire ya lithiamu. Mabatire a lithiamu nthawi zambiri amakhala ndi mitundu iwiri: mabatire a lithiamu zitsulo ndi mabatire a lithiamu-ion. Mabatirewa amagwiritsidwa ntchito kwambiri m'mafoni a m'manja, magalimoto amagetsi, zida zazing'ono zapakhomo, mafoni a m'manja, zolemba, zometa magetsi, ndi zina zotero, ndipo amagwiritsidwa ntchito kwambiri kuposa mabatire owuma.

Mabatire amagawidwa kukhala otha kuchajwanso (omwe amatchedwanso mabatire onyowa) ndi osathanso (omwe amatchedwanso mabatire owuma).

Pakati pa mabatire osathanso, mabatire a AA ndi omwe amatchedwa mabatire amchere.

Mabatire a lithiamu-ion ndi abwinoko. Kupirira kumakhala pafupifupi kasanu kuposa mabatire amchere, koma mtengo wake ndi kasanu.

Pakalipano, mabatire a lithiamu-ion No. 5 a Panasonic ndi Rimula ndi mabatire abwino kwambiri osatha. Mabatire omwe amatha kuchangidwanso amagawidwa kukhala nickel-cadmium, nickel-hydrogen, ndi lithiamu-ion mabatire owonjezeranso.

Pakati pawo, mabatire a lithiamu-ion ndi abwino kwambiri. Mabatire a Nickel-cadmium nthawi zambiri amakhala kukula kwa mabatire a AA, omwe ndi akale komanso ochotsedwa, koma amagulitsidwabe kunja.

Mabatire a Ni-MH nthawi zambiri amakhala kukula kwa No. 5 ndipo tsopano ndi mabatire apamwamba a 5, omwe ali ndi 2300mAh mpaka 2700mAh monga oyambira. Mabatire a lithiamu-ion amatha kucharged nthawi zambiri amakhala kukula kopangidwa ndi wopanga. Ponena za kupirira kwa mabatire omwe amatha kuchangidwanso, mabatire a lithiamu-ion omwe amatha kuchangidwa ndi abwino kwambiri, kutsatiridwa ndi nickel-metal hydride kenako nickel-cadmium.

Lifiyamu-ion akhoza kukhalabe mphamvu kuposa 90%, mpaka otsiriza pafupifupi 5% ya mphamvu, ndiyeno mwadzidzidzi kutha. Batire ya nickel-hydrogen ikupita njira yonse, kusonyeza kuti inali 90% pachiyambi, ndiye 80%, ndiyeno 70%.

Moyo wa batri wa mtundu uwu wa batri sungathe kukhutiritsa zinthu zamagetsi zamagetsi zomwe zimawononga kwambiri mphamvu, makamaka pamene kamera ya digito ikufuna kung'anima, zimatenga nthawi yaitali kuti atenge chithunzi china, ndipo batire yowonjezereka ya lithiamu-ion ilibe. vuto ili. Kotero ngati kamera si AA batire, adzakhala lithiamu-ion rechargeable batire yopangidwa ndi Mlengi.

Ichi ndi chisankho choyamba. Ngati ndi batire ya AA, mutha kugulanso batire ya nickel-metal hydride ndikugula charger yabwinoko. Ndibwino kuti mutulutse ndi kulipira poyamba, zomwe zidzatalikitsa moyo wa mkuntho.

Kufananiza kwa batire ya lithiamu ndi batri youma:

1. Mabatire owuma ndi mabatire otayidwa, ndipo mabatire a lithiamu ndi mabatire omwe amatha kuchangidwanso, omwe amatha kulipiritsidwa kangapo ndipo alibe kukumbukira. Sichiyenera kulipira molingana ndi kuchuluka kwa magetsi ndipo angagwiritsidwe ntchito ngati pakufunika;
2. Mabatire owuma ndi oipitsidwa kwambiri. Mabatire ambiri anali ndi zitsulo zolemera monga mercury ndi lead m’mbuyomu, zomwe zinayambitsa kuipitsa kwambiri chilengedwe. Chifukwa ndi mabatire otayika, amatayidwa mwamsanga akagwiritsidwa ntchito, koma mabatire a lithiamu alibe zitsulo zovulaza;
3. Mabatire a lithiamu amakhalanso ndi ntchito yothamanga mofulumira, ndipo moyo wozungulira umakhalanso wokwera kwambiri, womwe sungathe kufika kwa mabatire owuma. Mabatire ambiri a lithiamu tsopano ali ndi mabwalo oteteza mkati.
