Abstract

?-Mn3N2 is produced using solvothermal reactions between MnCl2 and LiNH2 in benzene. At 350 °C nanocapsule structures are obtained, whereas at higher temperatures samples consisted of isotropic nanoparticulates. In aqueous KOH solution capacitances were up to 300 F g?1 (2 mV s?1, potential window 0.3 to ?0.6 V vs. Hg/HgO), but capacitance fell to relatively low values on cycling. In lithium cells a reversible first cycle capacity of 600 mA h g?1 was obtained, and this decayed to 340 mA h g?1 after 50 cycles. In sodium cells a reversible first cycle capacity of 156 mA h g?1 was obtained and was maintained well on cycling (127 mA h g?1 in the 50th cycle).
