BITS Pilani scientists develop stable solid electrolytes for Li-Ion batteries

Jaipur: Indian researchers have developed a thermally stable solid electrolyte for lithium-ion batteries for energy storage that promise application for a wide range of temperatures from 30-500 degrees Celsius. 

A group of researchers led by Dr Anshuman Dalvi of the Department of Physics at Birla Institute of Technology and Science (BITS) at Pilani Campus have developed solid-state energy storage devices in the form of thermally stable solid electrolytes for Li+ ion batteries and supercapacitors and tested their stability and efficiency using state of the art facilities. This work has been published in the journal ‘Materials Research Bulletin in 2021.’  

The team has used the DST FIST-supported High-temperature X-ray diffraction (HTXRD) facility at Rigaku Smart Lab, particularly useful for the thermal stability assessment of novel solid electrolytes.  

“Ionic liquid composites with NASICONs, Garnets, and some other fast ionic solids have been found to be promising for high-temperature energy storage devices. These devices are strategically important for military and space applications.” Dr Anshuman Dalvi said. 

Energy generation and storage are the need of the hour, and worldwide efforts are being invested in developing cost-effective, efficient options. However, there are several scientific and technical limitations in the present technology. 

The efforts are being made to develop solid-state energy storage devices. The FIST program of the Department of Science and Technology (DST) of India-supported XRD facility has given a new dimension to the ongoing research by providing them infrastructural support to investigate composite materials at high temperature with great resolution.
