Summary
This study introduces a chemical reprogramming strategy to convert battery waste into new energy storage materials. The method transforms lithium cobalt oxide and plastic waste into a cobalt terephthalate anode for advanced dual-ion batteries.
Area of Science:
- Materials Science
- Electrochemistry
- Chemical Engineering
Background:
- Sustainable battery waste management is crucial for circular economy principles.
- Current recycling methods often focus on element recovery, not full component reutilization.
- Developing methods for transforming waste into functional materials is essential.
Purpose of the Study:
- To develop a novel chemical reprogramming strategy for battery waste valorization.
- To transform distinct waste components into functional energy storage materials.
- To establish a scalable pathway for circular energy storage.
Main Methods:
- Utilized a redox-ligand-coupled chemical reprogramming strategy.
- Employed LiCoO2 and polyethylene terephthalate (PET) as a model system.
- Applied hydrothermal conditions for in situ reconstruction into cobalt terephthalate (CoTPA).
Main Results:
- Successfully transformed battery cathode waste and PET into a redox-active CoTPA metal-organic framework.
- Achieved a CoTPA anode with high reversible capacity (≈1170 mAh g⁻¹) and excellent cycle stability.
- Demonstrated a closed-loop dual-ion battery (DIB) with regenerated graphite (RG) and CoTPA, achieving 304 Wh kg⁻¹ energy density.
Conclusions:
- The developed strategy enables the direct conversion of waste into high-performance energy storage materials.
- This chemistry-driven approach offers a scalable and sustainable pathway for battery recycling and circular energy storage.
- The method successfully extends to various layered oxide cathodes and PET sources.

Spontaneous Chemical Reactions
Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...

01:27Redox Reactions
Redox reactions are vital biochemical processes that underpin energy metabolism in cells. These reactions involve the transfer of electrons between molecules, occurring in tandem as oxidation and reduction. Oxidation refers to the loss of electrons, while reduction denotes their gain. This coupling ensures the seamless flow of electrons through metabolic pathways. For example, in bacterial metabolism, glucose undergoes oxidation to carbon dioxide, while oxygen is simultaneously reduced to...
01:24Redox Reactions
Oxidation-reduction or redox reactions involve the transfer of electrons from one molecule or atom to another. When an atom gains an electron, another atom must lose an electron, meaning oxidation and reduction must occur together. Since the redox occurs in pairs, the atom that gets oxidized is also called the reducing agent or reductant, and the atom that is reduced is also called the oxidizing agent or oxidant. A straightforward way to remember the definitions of oxidation and reduction is...
01:24Types of Reversible Electrodes
For electrode reversibility to be maintained, all the reactants and products involved in the half-reaction must be present at the electrode. There are several types of reversible electrodes (half-cells).In metal-metal-ion electrodes, a metal balances electrochemically with a solution of its own ions. Examples are Cu2+|Cu and Zn2+|Zn. Metals that react with the solvent, like group 1 and most group 2 metals, which react with water, and zinc, which reacts with aqueous acidic solutions, cannot be...
03:12Batteries and Fuel Cells
A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...
01:28Electrochemical Cells
Electrochemical cells are systems that convert chemical energy into electrical energy or use electrical energy to drive chemical reactions. They consist of two electrodes in contact with an electrolyte, where redox reactions enable electron transfer. Most electrochemical cells include two half-cells connected by an external wire for electron flow and a salt bridge for ion flow. The salt bridge contains an electrolyte solution and maintains charge neutrality by allowing ions—not electrons—to...
