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.

Market Demand

With the rapid development and broad application of mobile devices, electric and unmanned vehicles, as well as with the rise of smart grids and networks for “the internet of things”, the demand for batteries with:

• Higher performance
• Lower cost
• Lower environmental burden

is rapidly growing.

Challenges and Strategies

In order to address the aforementioned challenges, various strategies emerged over the past few years for the development of advanced composite cathodes designed for:

1. High sulfur utilization
2. 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. This will enable a significant boost in the cycling stability, without sacrificing its performance (i.e., capacity).

Implementation Plan

This will be achieved through the implementation of:

• Cost-effective materials
• Processes

Additionally, we aim to take our Technology Readiness Level from 2 to 4, thus shaping a significant business opportunity, enabling us to continue development within an EIC Transition project.
