ABSTRACT
The demand for microelectronic devices has led to extensive research on energy storage devices, like lithium-ion batteries (LIBs), supercapacitors etc. Among the different energy storage solutions, LIBs are the most promising energy storage devices, exhibiting higher energy and power density than other electrochemical energy storage devices. Clay is a natural compound formed as a result of the disintegration of igneous rocks. The differences between the synthesis methods strongly influence the performance and properties of the composite electrolyte. The ultrasonication or mechanical mixing causes the de-stacking of the clay layers. Completely exfoliated structures are seen to exhibit the best physico-mechanical and electrochemical performances. Polyvinylidene difluoride is a well-known matrix for polymer electrolyte in LIBs. The improved capacity of the electrolyte is attributed to the honeycomb porous structure, that can efficiently trap the liquid electrolyte to achieve the best electrochemical performance.
