Practical Cell Design for PTMA-Based Organic Batteries: an Experimental and Modeling Study.

ABSTRACT: Poly(2,2,6,6-tetramethyl-1-piperidinyloxy methacrylate) (PTMA) is one of the most promising organic cathode materials thanks to its relatively high redox potential, good rate performance, and cycling stability. However, being a p-type material, PTMA-based batteries pose additional challenges compared to conventional lithium-ion systems due to the involvement of anions in the redox process. This study presents a comprehensive approach to optimize such batteries, addressing challenges in electrode design, scalability, and cost. Experimental results at a laboratory scale demonstrate high active mass loadings of PTMA electrodes (up to 9.65 mg cm^-2), achieving theoretical areal capacities that exceed 1 mAh cm^-2. Detailed physics-based simulations and cost and performance a
