Functionalized Graphene Based Electrode Material for Lithium Sulfur Batteries

Introduction

FunGraB project addresses the pressing need for ecofriendly, sustainable, and rechargeable batteries with high capacity, energy density, and long lifespan, which will significantly expand the energy storage market.

Background

With the rapid development and broad application of mobile devices, electric and unmanned vehicles, as well as the rise of smart grids and networks for “the internet of things”, the demand for batteries with higher performance, lower cost, and lower environmental burden is rapidly growing.

In order to address the aforementioned challenges, various strategies emerged over the past few years for the development of advanced composite cathodes designed for high sulfur utilization and stability. In particular, the pinning of sulfur is pursued by engineering materials as high-affinity hosts for sulfur to hinder the shuttling of lithium polysulfides.

Project Goals

FunGraB project aims to deliver the upscaling of an industrially-relevant one-step novel manufacturing process for lithium-sulfur batteries electrode material, enabling a significant boost in the cycling stability, without sacrificing its performance (i.e., capacity).

Implementation Strategy

This will be achieved through the implementation of cost-effective materials and processes along with taking our Technology Readiness Level from 2 to 4, thus shaping a significant business opportunity (enabling us to continue development within an EIC Transition project).
