Lithium-ion batteries (LIBs) are crucial for energy storage but pose environmental and health risks due to toxic materials like lithium, cobalt, and nickel. Their rapid increase raises concerns about soil and water contamination from improper disposal, highlighting the need for effective recycling.
Li-ion batteries come in various compositions, with lithium-cobalt oxide (LCO), lithium-manganese oxide (LMO), lithium-iron-phosphate (LFP), lithium-nickel-manganese-cobalt oxide (NMC), and lithium-nickel-cobalt-aluminium oxide (NCA) being among the most common. Graphite and its derivatives are currently the predominant materials for the anode.
Here is the average mineral composition of a lithium-ion battery, after taking account those two main cathode types: The percentage of lithium found in a battery is expressed as the percentage of lithium carbonate equivalent (LCE) the battery contains. On average, that is equal to 1g of lithium metal for every 5.17g of LCE. How Do They Work?

The modern lithium-ion battery (LIB) configuration was enabled by the “magic chemistry” between ethylene carbonate (EC) and graphitic carbon anode. Despite the constant changes of cathode chemistries with improved energy densities, EC-graphite combination remained static during the last three decades.
Dismantling of LIBs reveals a complex structure of various components, each with specific physical characteristics. The outer casing, current collectors, electrodes, separator, electrolyte, and tabs each play a dynamic role in the battery's function and are designed to efficiently store and release electrical energy.
A lithium-ion polymer (LiPo) battery (also known as Li-pol, lithium-poly, and other names) is a type of Li-ion battery with a polymer electrolyte instead of a liquid electrolyte. All LiPo batteries use a high-conductivity gel polymer as the electrolyte. Lithium polymer cells have evolved from lithium-ion and lithium-metal batteries.
This paper reviews the development of structural capacitors, including structural dielectric capacitors and structural supercapacitors, and provides the first enunciation of their engineering design and applications.
Due to the strong effect of the composite fabrication method on the structural capacitor performance, the structure development should be performed with the involvement of composite engineers. Structural development should be conducted with inclusion of the electrical contacts in the overall design.
Structural capacitors are structural materials (commonly polymer-matrix structural composites) that have been modified in order to render the capacitor function for the purpose of electrical energy storage. They are a type of multifunctional structural material.
Since service life and safety are essential for structural capacitors, dielectric structural capacitors are more promising than structural supercapacitors, in spite of the fact that the capacity for small-scale energy storage tends to be greater for a supercapacitor than a dielectric capacitor.
For a structural supercapacitor, the dielectric film (known as a separator) should be an ionic conductor and an electronic insulator. The design of a structural capacitor should include consideration of the capacitance of the interface between the dielectric film and electrode.
Cement-based structural supercapacitors (CSSC) are a novel energy storage component that combines electrical energy storage with structural load-bearing capabilities, offering the potential to replace traditional building components and enabling large-scale energy storage at the building level.
Structural supercapacitors (SSCs) have high specific capacitance combined with mechanical strength. This review explores high-performance SSC component fabrication with improved mechanical and electrochemical properties. Importance of fabrication, standard tests for optimizing SSC performance in structural applications emphasized.
