The demand for efficient energy-storage solutions has led to a growing interest in lithium-ion batteries (LIBs) due to their high energy and power density. LIBs have proven to be ideal for various applications, including electric vehicles and hybrid electronic devices.

The development of LIBs began in the late 1960s and early 1970s when primary lithium-ion batteries emerged. Researchers like Matsushita and Moser showcased primary LIBs using different electrolytes and cathode materials. This led to the development of the first rechargeable secondary LIBs by pioneers like Whittingham, Armand, Goodenough, and Scrosati.

A significant breakthrough occurred in 1991 when Sony introduced rechargeable LIBs with a LiCoO2 cathode and graphite anode. This marked the second generation of LIBs and further advancements in energy density. The discovery of the affordable and environmentally-friendly LiFePO4 cathode in 1997 opened up new opportunities for LIBs as an alternative to fossil fuels.

The fundamental principles of lithium-based batteries remain the same, regardless of the electrode material used. During the charging cycle, lithium ions move from the cathode to the anode through the separator and electrolyte. When the battery is discharged, the lithium ions move from the anode to the cathode, releasing energy to power the battery.

The electrode in a lithium-ion battery plays a crucial role in determining its performance. To optimize battery performance, cyclodextrin architectures have been used to improve lithium-based batteries. These architectures create new functional organic polymers that enhance the performance of the battery components.

Cyclodextrins, derived from the breakdown of starch, are cage-like molecules with a hydrophobic cavity in the center. This unique property allows cyclodextrins to encapsulate other molecules, improving their properties. Cyclodextrins are widely used in various industries such as pharmaceuticals, food, and cosmetics.

In the context of lithium-ion batteries, cyclodextrin supramolecular chemistry enables the incorporation of cutting-edge functionalities into polymeric materials, enhancing the performance of the batteries.

The advancements in lithium-ion batteries and the use of cyclodextrin architectures have opened up new possibilities for energy storage and have the potential to reduce reliance on fossil fuels.

Overall, the continuous research and development in lithium-ion batteries, along with the utilization of cyclodextrin architectures, are paving the way for more efficient and environmentally-friendly energy storage solutions.
