New materials for electrochemical energy sources.
Conferencia; 3rd International Conference on Nanotechnology and Materials Science; 2019
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 for their 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, hybrid materials (IL-glass) and new NASICON type compositions. In all of them, the main ionic carrier is the Lithium cation.Additionally, nano- structured carbon composite and decorated nano- particles materials for electrodes properties and performance are presented. Our main goal has been to improve not only the electrolyte ionic conductivity but also to reach electrode materials that fits -as good as it can- at the interface between both; one of the most important issues to overcome in order to obtain a new generation of all-solid state batteries.
