Dr Chinmoy Das, Assistant Professor from the Department of Chemistry, and scholars Mr Sushant Wakekar and Mr Sasikumar K have published their invention titled “Li-based solid-state electrolyte and a method for its preparation” in the Indian Patent Office (Patent application No. 202441083351). The invention illustrates how to synthesise inexpensive Li(I) ion-based solid-state electrolytes that are feasible for fabricating flexible electronic devices. The team worked on inexpensive and readily available starting materials that provide self-supported and flexible solid-state electrolytes to advance LIB applications.
Abstract
In our invention, we described a rapid and robust synthetic methodology to prepare novel flexible solid-state electrolytes (SSEs) suitable for the fabrication of eco-friendly lithium-ion batteries (LIBs). The mechanically flexible film has been synthesized upon in situ incorporation of Li(I) ion into two inexpensive biocompatible polysaccharide matrices through mixing. We achieved Li(I) ion-based superionic conductivity at room temperature which is feasible for the fabrication of flexible electronics in modern age society.
Practical Implementation/Social Implications of the Research
This invention can be implemented in various industries, such as electric vehicles (EVs), wearable and flexible electronics, and aerospace and aviation.
The team is extending their research towards the fabrication of cheaper sodium (Na+), potassium (K+)-ion based solid-state electrolytes with superionic conductivity and implementing them in designing the biodegradable sodium-ion / potassium ion batteries (NIBs / KIBs).
