常温作動のAl/AlCl<sub>3</sub>－1－ブチルピリジニウムクロリド／ポリアニリン型二次電池
摘要
Al／Alc13※Butylpyridini㎜ chl・ride(BPc)／P・1yaniline(PAn)sec・ndarycell has been developed。 This cell operates at roQm temperature． The PAn was electrochemically synthes ize(L Three type PAn electrodes， powder， pellet， and film electrodes， were made． In the case of the powder e！ectrode， the open circuit vQltage of the cell was l・7 V， and the capacity， the energy density7 an(1 the charge／discharge eff ic iency were 65 Ah／kg， 80 wh／kg｝ and 85-90％， respect ive！y． When benzene was added to the electrolyte， the capac ity， the energy (iensity， and the efficiency of the electrode became 80 Ah／kg， 110 wh／kg， and 90 ％， respectively。 The degree of self-discharge of the electrode was ca・ 7 ％ after one month storage． The maj or anion species in the e！ectrolyte， Al2Cl7一， was considered to be the dopant of the PAn electro(le in the cell・
