At its most basic, a battery has three main components: the positive electrode (cathode), the negative electrode (anode) and the electrolyte in between (Fig. 1 b).

This review investigates the various development and optimization of battery electrodes to enhance the performance and efficiency of energy storage systems. Emphasis is placed on the material composition, structural design, and fabrication processes of electrodes.
We hope that this Account will make an invaluable contribution to the development of organic electrode materials for next-generation batteries and help to unlock a world of potential energy storage applications.
A rechargeable battery comprises two electrodes – the cathode and the anode – separated by an electrolyte (Fig. 1). Alkali ions shuttle between the two electrodes, with the electrolyte acting as an alkali-ion conductor and electrical insulator.
These highlight the increasing demand to explore advanced materials that enhance the efficiency, durability, capacity, and performance of battery-based electrochemical energy storage (EES) technologies, particularly those that empower electric vehicles, off-grid electricity, and stationary systems.

As the energy storage device combined different charge storage mechanisms, HESD has both characteristics of battery-type and capacitance-type electrode, it is therefore critically important to realize a perfect matching between the positive and negative electrodes.
On its most basic level, a battery is a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell contains a positive terminal, or cathode, and a negative terminal, or anode.
This manuscript highlights and classifies several recent studies on organic electrode materials and lists their potential applications in various battery systems.
Whether a traditional disposable battery (e.g., AA) or a rechargeable lithium-ion battery (used in cell phones, laptops, and cars), a battery stores chemical energy and releases electrical energy.
A lot of research in recent years has been done on cell design and electrode structuring concerning the improvement of battery life, energy, and power density. Increasing the areal capacity of electrodes is the major approach to enhance the energy density of lithium-ion batteries (LIBs).

The design and fabrication of advanced electrodes for energy storage are vital in enhancing the performance, efficiency, and durability of batteries. This includes a multi-disciplinary approach incorporating materials science, electrochemistry, and engineering.
In contrast, the battery-type materials have a relatively high energy density, but their application is limited by the low conductivity, large volume expansion, slow diffusion of ions in the body phase of the electrode materials during the charge/discharge process. This will lead to a low energy density in a small current.
In particular, the classification and new progress of HESDs based on the charge storage mechanism of electrode materials are re-combed. The newly identified extrinsic pseudocapacitive behavior in battery type materials, and its growing importance in the application of HESDs are specifically clarified.
However, the rapid increase in their annual production raises concerns about limited mineral reserves and related environmental issues. Therefore, organic electrode materials (OEMs) for rechargeable batteries have once again come into the focus of researchers because of their design flexibility, sustainability, and environmental compatibility.
Electroneutrality is maintained by the flow of electrons from the negatively charged anode to the positive cathode via the external circuit. When the battery is recharged, an external load reverses the flow of ions and electrons back into the negative electrode (Table 2).
