Organic compounds have long been sought as positive electrodes for lithium rechargeable batteries because they frequently offer a significant advantage over inorganic materials, e.g. PAQS[1] provides a promising energy-storage system by linking the anthraquinone unit with the thioether bond. Proves its high utilization and high coulomb efficiency, excellent cyclability and satisfactory rate capability(198 mAh g-1). and Minh Chau Pham’s PANQ[2,3], which has nearly 300 mAh g-1 at the beginning of cycling, corresponds nicely to the theoretical value calculated for the polymer. Novak and Dietrich
reported that PEDOT was utilized as cathode activematerial in 0.1M Bu4NPF6/PC and 0.1MBu4NPF6/CH2Cl2 and a high specific capacity of 140 mAh g-1 was obtained, which was higher than other conducting polymers, such as PAni, PPy, PPP, PT and PDTT [4,5].
In the past twenty years, many polymers have been investigated as cathode materials for lithium batteries. The most favored structure of applicable polymers is based on S-S bonds[6,8]. Unfortunately, although they have high theoretical capacity (〉300 mAh g-1), the utilization ratio is usually low and the cyclability is very poor, mainly due to the slow reaction kinetics and unwanted dissolution in the nonaqueous electrolyte.These problems seem impossible to be eventually solved through structure optimization. So we have tried to develop new energy storage systems not based on S-S bonds.In this paper, we demonstrate a novel easy-synthesized polymer named 1,4,5,8-tetra -hydroxy-Hexylbenzo-tetraquinone, which shows high specific capacity and cyclability. This article  develops the new energy from  the point of view, make HBTQ applies to rechargeable lithium batteries, thus supplies the information for lithium battery's development.

Organic compounds serve as positive electrodes for lithium rechargeable batteries advantageous over inorganic materials.  Prototype examples include PAQS[1] that provides a promising energy-storage system by linking the anthraquinone unit with the thioether bond with high utilization and high coulomb efficiency, excellent cyclability, and satisfactory rate capability (198 mAh g-1).  as well as  Minh Chau Pham’s PANQ[2,3] that have nearly 300 mAh g-1 at the beginning of cycling, corresponding to the theoretical value calculated for the polymer. Novak and Dietrich reported that PEDOT was utilized as cathode activematerial in 0.1M Bu4NPF6/PC and 0.1MBu4NPF6/CH2Cl2 with a high specific capacity of 140 mAh g-1, which was higher than alternative conducting polymers, such as PAni, PPy, PPP, PT and PDTT [4,5].

During the past twenty years, a wealth of polymers have been investigated as cathode materials for lithium batteries. The most favored structure of applicable polymers is based on S-S bonds [6,8]. While they have high theoretical capacity (〉300 mAh g-1), the utilization ratio is typically low and the associated cyclability is very poor, mainly due to the slow reaction kinetics and undesired dissolution in the nonaqueous electrolyte. These issues seem formidable through structure optimization. Here we report our attempts in developing new energy storage systems other than based on S-S bonds. In this paper, we demonstrate a novel easy-to-be-synthesized polymer referred to as 1,4,5,8-tetra -hydroxy-Hexylbenzo-tetraquinone. The polymer shows high specific capacity and cyclability, and is a promising new energy material. As it can be applied to rechargeable lithium batteries, HBTQ is important for the associated development.
