New glassy hybrid materials for electrochemical green energy storage.
Simposio; ISyDMA?5 Virtual Edition; 2020
The 21st Century is marked by the paramount importance of new sources of green Energy develop. At present, an efficient energy use and renewable and clean sources for a sustainable growth is needed. This is why, finding diverse energy storage methods is the aim of much of our research interest today and also, for many Governments around the world. Batteries and supercapacitors are two common ways to storage electrochemical energy. Lithium ion batteries (LIBs) are today the most important and widely used rechargeable batteries, having the following advantages: high voltage, low self-discharge, long cycling life, low toxicity, and high reliability. The performance of these devices depends on the materials used both for their electrodes and electrolytes. Unfortunately, a very precise materials selection is not enough to guarantee good functionality; one of the biggest technology challenges is to find couples of materials -electrode/electrolyte-with high compatibility. In this presentation, it is reviewed some of our most recent results for electrolytes: glassy material and glassy hybrid materials (IL-glass) where, in all of them, the main ionic carrier is the Lithium cation.Our main goal has been to improve not only the electrolyte ionic conductivity but also to find the proper electrode materials that fits -as good as it can- at the interface, one of the most important issues to overcome, in order to obtain the new generation of all-solid state batteries.
