| Abstract |
Poly (hexyl viologen chloride) (PHV-Cl) is examined as a versatile electrode material in magnesium-based electrolytes. When coupled with Mg metal in commonly used Mg-based electrolytes for the operation via a dual-ion mode, PHV-Cl cathodes shows a quite stable anion insertion/desertion behavior during charge/discharge. PHV-Cl delivers a capacity of 170 mAh.g-1 at an average discharge voltage of 1.33 V vs. Mg/Mg2+, including a significantly higher energy density (ED) than chevrel Mo6S8 (226 vs. ca. 100 mWh.g-1). This feature of PHV-Cl is retained after repeated cycle in all the electrolytes examined (201 mWh.g-1 after 50 charge/discharge cycles). PHV-Cl has been tested in several electrolytes (APC, MACC and Mg(HDMS)2) and reveals that PHV-Cl can be used as a cathode material in MIB’s. TGA study is done at different discharged state (full discharged, ¾ discharged, ½ discharged and ¼ discharged state) to confirm that Ph2AlCl2- anion insertion in PHV-Cl. It is described that PHV-Cl can be used as an anode in anion batteries. Further, full cell investigation of PHV-Cl is in progress. |
