PROJECT
GRAPHENE ANODE
Nowadays, there is a worldwide demand for the development of batteries capable of meeting the increasingly requirements in the mobility and electronics sectors.
UNDERSTANDING THE PROJECT
Lithium-ion batteries (LIBs) dominate the current market and are applied as main power sources for portable electrical devices. Limitations of the materials used in the battery, anode and cathode components, hinder the development of high performance LIBs for electric vehicles and energy storage systems.
Spherical graphite is a key anode ingredient in these batteries, but its limited reversible capacity and the low diffusion rate of lithium inside the anode contribute to a low power density battery.
The project “Graphene anode for lithium-ion batteries” is within this context to develop a new technology that results in a new anode. This anode will have carbon nanomaterials, like graphene, as the main component.
Compared to graphite, graphene is a material with a greater specific surface area and greater electrical and thermal conductivity.
THE IDEIA
The idea is that these carbon nanomaterials comprise the main component of this new anode so that the properties inherent in the nanomaterial reflect in the performance improvement of the battery
The Centelha Program
The Centelha Program is the starter impulse of this Project. Centelha offers training, financial resources, and support to turn ideas into successful businesses. More than 500 ideas were submitted to the state of Minas Gerais, and the project “Graphene anode for lithium-ion batteries” was among the selected ones
What was done
With the financial resources and partnerships established through the Centelha Call for Proposals (funded by FAPEMIG and FINEP), the project advanced through the development chain, reaching the tested prototype stage. A commercial graphene oxide was tested and combined with other carbon materials, resulting in the prototype anode (the reduced graphene foil).
