Abstrakt: Nickel (II) phthalocyanine-tetrasulfonic acid tetrasodium salt, with super chemically stability and high electrochemical capacity, is proposed as novel organic anodes. Ex situ FTIR patterns evidence the bonding effects between positively charged Li ions and negatively charged Pc molecules, which greatly benefits the stable reversibility and real capacity of TsNiPc. To conquer the poor conductivity of the organic molecular, graphene oxide/TsNiPc composites have been fabricated through a facile hydrothermal freezedrying method. The capacity of TsNiPc@GO was maintained at 455 mAh g-1 after 100 cycles, when the capacity of 99.8 mAh g-1 from carbon was subtracted, the true capacity of TsNiPc was 335.2 mAh g-1, which was superior to many organic anodes.
