Alumina ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri komanso yogwiritsidwa ntchito kwambiri. Mutha kuiwona kulikonse. Kuti izi zitheke, ntchito yabwino kwambiri ya alumina yokha komanso mtengo wotsika wopanga ndizo zomwe zimapangitsa kuti izi zitheke.
Apa ndi pomwe tikufotokozeranso kuti ndi ntchito yofunika kwambiri yaufa wa alumina, ndiko kuti, chophimba cha diaphragm cha batire ya lithiamu. Diaphragm monga gawo limodzi lofunika kwambiri la batire ya lithiamu-ion, imatha kupewa kukhudzana ndi zabwino ndi zoyipa ndikulimbikitsa shuttle ya lithiamu ion pakati pa ma electrode, zomwe zimatsimikiza magwiridwe antchito ndi chitetezo cha batire. Diaphragm yachikhalidwe ya polyolefin ili ndi malo otsika osungunuka komanso kukhazikika kosakhazikika pa kutentha kwambiri, zomwe zimakhudza kwambiri chitetezo cha batire, chophimba cha ufa wa inorganic ultrafine kapena polymer yosinthidwa ndi composite ndi njira imodzi yothandiza yowonjezerera kukhazikika kwa kutentha kwa diaphragm.
Pofuna kukonza magwiridwe antchito a lithiamu batire separators, tinthu ta aluminiyamu oxide titha kuphimbidwa pamwamba pa polyolefin separators mothandizidwa ndi ma polymer binders. Alumina imagwira ntchito bwino kwambiri chifukwa cha kukana kutentha kwambiri, ndipo imatha kusunga umphumphu wa diaphragm ngakhale kutentha kwambiri kwa 180°C. Kuphatikiza apo, imalepheretsanso HF yaulere mu electrolyte kuti iwonjezere kukana kwa asidi ndi magwiridwe antchito otetezeka a batire; imatha kupanga yankho lolimba mu batire ya lithiamu kuti iwonjezere mphamvu ya liwiro ndi magwiridwe antchito a cycle, imakhala ndi kunyowa bwino, komanso ili ndi mphamvu zina zoyamwa ndi kusunga madzi, ndi zina zotero.
Ponena za kugwiritsa ntchito, ma batire olekanitsa okhala ndi alumina okhala ndi alumina amakondedwa ndi atsogoleri ambiri amakampani. Makampani monga Sanyo, LG, ndi Maxell onse agwiritsa ntchito ma batire olekanitsa okhala ndi alumina kuti apititse patsogolo chitetezo cha batire.
Zhengzhou Xinli Wear-Resistant Materials Co., Ltd. ingaperekeufa wa aluminapazifukwa zosiyanasiyana. Takulandirani kuti muyike oda kuti mukafunse mafunso.
