• Resumen

  • This thesis investigates the development and optimization of advanced aqueous and non-aqueous (semi)organic batteries, focusing on Conjugated Microporous Polymer (CMP) electrodes. The research aims to enhance the electrochemical performance, practicability, and sustainability of organic batteries while addressing key challenges such as poor processability, slow kinetics, high solubility, and low practicability issues of organic electrodes. With the broader goal of advancing organic batteries, this thesis is structured into several chapters, each addressing distinct yet interconnected aspects of the research. The structure includes: Chapter 1: Overview of the research background and challenges in CMP-based battery systems.

    Chapter 2: Objectives of the thesis.

    Chapter 3: Methods for CMP synthesis, characterization, and battery testing.

    Chapters 4–8: Key findings, including: Chapter 4: Development of anthraquinone-based CMP anodes for alkaline batteries, achieving high energy density and improved practicality.

    Chapter 5: Phenazine-based CMP (IEP-27-SR) showing high hydronium-ion storage in acidic media.

    Chapter 6: IEP-27-SR paired with MnO₂ cathodes for high-performance acid batteries.

    Chapter 7: IEP-27-SR's application in lithium-ion batteries with optimized electrolytes.

    Chapter 8: IEP-27-SR as a cathode for aluminum metal batteries with exceptional durability.

    Chapter 9: Conclusions and future challenges.

    This research advances CMP-based battery technologies with significant performance improvements across various systems.
