From the Instituto Tecnológico de la Energía (ITE) we have the objective of facilitating the process of sustainable and efficient energy transition to companies and society.
Development of sustainable Si/C anodes by screen-printing techniques, integration of cells with commercial components and modeling of electrochemical, thermal and electrical behaviour for lithium batteries
Description
The SINCLAIR project aims to improve the properties of lithium-ion batteries by developing sustainable Si/C-based anodes using the screen-printing technique, a novel technique in this field. In addition, the integration and validation of graphite and Si/C cells with commercial materials, as well as the use of modeling techniques to evaluate the electrochemical and thermal behaviour of the cells and to reproduce the electrical behaviour due to polarization phenomena, will be carried out.
This project is aligned with the European roadmaps where Generation 3 batteries are identified as the next technology to break into the energy storage market. This battery technology is based on the incorporation of silicon anodes because of the high capacity they provide. In addition, the project’s focus on obtaining sustainable anodes from waste represents a step towards the circular economy.
Objectives
Obtaining a sustainable Si/C based anode from waste, which will be subsequently modified, adapted and integrated in the formulation of an anode for lithium cells, using the silk-screen printing technique.
Integration and assembly of cells with commercial materials. Graphite anode cells will be integrated to serve as reference and Si/C based anode cells with an approximate capacity of 500mAh.
Evaluation of the electrochemical and thermal behaviour of graphite and graphite-silicon anodes, using finite element models from the integration of graphite and Si/C cells and evaluation of the electrical behaviour of the battery to faithfully reproduce the polarization curve of batteries in order to achieve extended life and charging efficiency
