Kodi mabatire a magalimoto atsopano ndi ati?

Magalimoto amagetsi atsopano akuchulukirachulukira kukhala chisankho choyamba kwa anthu ambiri kugula magalimoto.Iwo ndi anzeru komanso okwera mtengo kuposa magalimoto amafuta, koma mabatire akadali nkhani yayikulu, monga moyo wa batri, kachulukidwe, kulemera, mtengo ndi chitetezo.Ndipotu, pali mitundu yambiri ya mabatire amphamvu.Lero, ndilankhula nanu za mitundu yosiyanasiyana ya mabatire amphamvu atsopano omwe alipo panopa.
Chifukwa chake, mabatire amagetsi apano nthawi zambiri amaphatikiza mitundu yotsatirayi, yomwe ndi mabatire a ternary lithiamu, mabatire a lithiamu iron phosphate, mabatire a lithiamu cobalt oxide, mabatire a faifi tambala achitsulo, ndi mabatire olimba.Pakati pawo, ma tramu amphamvu atsopano nthawi zambiri amagwiritsa ntchito mabatire a ternary lithiamu ndi mabatire a lithiamu iron phosphate, omwe amatchedwa "ngwazi ziwiri zopikisana ndi hegemony".

Ternary lithiamu batire: Yodziwika bwino ndi nickel-cobalt-manganese mndandanda wa CATL.Palinso mndandanda wa nickel-cobalt-aluminium pamakampani.Nickel imawonjezedwa ku batri kuti iwonjezere mphamvu yosungira batire ndikusintha moyo wa batri.
Amadziwika ndi kukula kwakung'ono, kulemera kopepuka, kachulukidwe kakang'ono ka mphamvu, pafupifupi 240Wh/kg, kusakhazikika kwamafuta, komanso sachedwa zovuta kuyaka modzidzimutsa.Imalimbana ndi kutentha kochepa koma osati kutentha kwambiri.Kutsika kwapakati pakugwiritsa ntchito kutentha kumatsika ndi 30 ° C, ndipo mphamvu imachepetsedwa ndi 15% m'nyengo yozizira.Kutentha kothawirako kumakhala kozungulira 200 ° C-300 ° C, ndipo chiwopsezo cha kuyaka modzidzimutsa ndi chachikulu.

Lithium iron phosphate batire: imatanthawuza batire ya lithiamu-ion yomwe imagwiritsa ntchito lithiamu iron phosphate ngati zinthu zabwino za elekitirodi ndi kaboni ngati zinthu zopanda ma elekitirodi.Poyerekeza ndi mabatire a ternary lithiamu, kukhazikika kwake kwamafuta kumakhala bwino ndipo mtengo wake wopanga ndi wotsika.Kuphatikiza apo, moyo wozungulira wa mabatire a lithiamu iron phosphate udzakhala wautali, nthawi zambiri 3,500, pomwe mabatire a ternary lithiamu nthawi zambiri amayamba kuwola pafupifupi nthawi 2,000 pakulipiritsa ndikutulutsa.
Lithium cobalt oxide batire: Batire ya lithiamu cobalt oxide ndi nthambi ya batri ya lithiamu-ion.Mabatire a lithiamu cobalt oxide ali ndi mawonekedwe okhazikika, kuchuluka kwamphamvu komanso magwiridwe antchito abwino kwambiri.Komabe, mabatire a lithiamu cobalt oxide ali ndi chitetezo chochepa komanso mtengo wokwera.Mabatire a lithiamu cobalt oxide amagwiritsidwa ntchito makamaka pamabatire ang'onoang'ono komanso apakatikati.Ndi batire wamba muzinthu zamagetsi ndipo nthawi zambiri sagwiritsidwa ntchito m'magalimoto.
Batire ya Nickel-metal hydride: Batire ya Nickel-metal hydride ndi mtundu watsopano wa batri wobiriwira wopangidwa m'ma 1990s.Lili ndi makhalidwe amphamvu kwambiri, moyo wautali, ndipo palibe kuipitsa.Electrolyte ya mabatire a nickel-metal hydride ndi njira yosayaka ya potaziyamu hydroxide, kotero ngakhale mavuto ngati batire afupikitsa achitika, nthawi zambiri samayambitsa kuyaka modzidzimutsa.Chitetezo chimatsimikizika ndipo njira yopangira ndi yokhwima.

Komabe, kutha kwa mabatire a nickel-metal hydride ndikokwanira, sikutha kugwiritsa ntchito kuthamanga kwamagetsi othamanga kwambiri, ndipo magwiridwe ake ndi oyipa kwambiri kuposa mabatire a lithiamu.Chifukwa chake, atagwiritsidwa ntchito kwambiri mabatire a lithiamu, mabatire a nickel-metal hydride amathanso kusinthidwa pang'onopang'ono.
