ActiveCath
Active energy storage using 3D lithium-ion thin-film cathodes: a new approach with sputtering technology

Challenge

ActiveCath seeks to develop a new technology in the field of Li batteries, in line with the use of more sustainable materials, in line with the objectives of the Green Deal. In addition, environmental and social challenges, such as the deal footprint, performance and durability, reuse and recycling, are present in the development of this project.

Solution

The main objective of ActiveCATh is to develop an active and multifunctional HE-NCM thin-film cathode with high energy density in 3D through a new scientific approach of sputtering, monitoring its climate impact through life cycle analysis.

Objectives, Activities and Results expected / achieved

ActiveCATh's innovation consists of establishing a new emerging battery technology using a new scientific sputtering approach to develop thin film cathodes composed of porous 3D HE-NCM thin films with a functional Ni concentration gradient.

The project encompasses the following developments:
(1) Deposition of 3D HE-NCM thin films by sputtering.
(2) Study of the electrochemical life cycle of the HE-NCM thin film cathode.
(3) Evaluation of the life cycle of the HE-NCM cathode.

The aim of these activities is to:
(i) Obtain a high-quality 3D HE-NCM thin-film cathode with stabilised morphology, chemical composition, phase distribution and electrolyte-cathode interphase, exhibiting multifunctionalities;
(ii) Establishing a new emerging battery technology through the synergistic and innovative combination of the developed cathodes with the sputtering technique;
(iii) Obtaining results that drive the development of new Li batteries in order to reduce the use of materials in the production of cathodes, with a positive impact on the management of natural resources.
