In literature are described various types of organic materials which exhibit multi-electron transitions during charging/discharging cycles, enabling high specific capacity typically in the range 300-800 mA.h/g [1]. Although many organic cathodes exhibit high specific capacity in solid-state batteries, negative properties such as cycling instability, low electrical conductivity, or high solubility in the electrolyte are still present. The simplest quinone derivatives are usually represented by simple quinoid structures such as 1,4-benzoquinone, 9,10-phenanthroquinone [9,10] or 9,10-anthraquinone. The last one exhibits in cell with a specific capacity of 222 mA.h/g [2]. Higher stability in terms of cycling, exhibited sulfo-substituted materials or polymeric materials prepared by the Phillips method from 9,10-anthraquinone monomer by reaction with sodium sulphide [3]. The poly(anthraquinonyl sulfide) [3] shows a initial specific capacity of 198 mA.h/g (88% theoretical) and 178 mAh/g after 200 cycles. The presented study is focused to development of printed electrodes where the commercial 9,10-anthraquinone (AQ) (DEZA a. s., CZ) and synthetized poly (1,5-anthraquinonyl sulfide) (PAQS) were used as a electrode materials. The PAQS were synthetized according Song work [3]. From both materials were prepared homogeneous ink formulations with viscosity related to screen/stencil printing. The electrodes were printed on Al and Cu foil with up to 14 mg of active material per cm2. In the cells Li/AQ, Li/PAQS the organic electrodes on Al were used and for Cu collector based in the cells AQ/LMO, PAQS/LMO. In all cells the LiTFSI based electrolytes was used. The stencil printing was realized using semiautomatic screen printing machine Ekra E1. Assembling and characterization of the Li foil based cell was performed under inert condition using glovebox with Ar atmosp	Printing; lithium battery; PAQ
