Goodenough*a ? ?? ?? ?a Texas Materials Institute and Materials Science and Engineering Program, The University of Texas at Austin, Austin, USA ? ?? ?? ?? ?E-mail: jgoodenough@mail.utexas.edu GA.gif 摘要:The mineral eldfellite, NaFe(SO4)2, is characterized as a potential cathode for a Na-ion battery that is fabricated in charged state; its 3 V discharge versus sodium for reversible Na+ intercalation is shown to have a better capacity, but lower insertion rate than Li+ intercalation. The theoretical specific capacity for Na+ insertion is 99 mA h g?1. After 80 cycles at 0.1C versus a Na anode, the specific capacity was 78 mA h g?1 with a coulomb efficiency approaching 100%. 0000055234.gif查看更多7个回答 . 8人已关注
