3DSTORE will fabricate solid-state batteries for IoT devices by 3D printing

  • Energy storage

3DSTORE (PLEC2022-009412) is a project granted within “Strategic Lines” programme  entitled “3D Printing All-Solid State Batteries for the Internet of Things Applications”, in which IREC is the coordinator. The aim of such programme is to support industrial research projects carried out in cooperation between companies and R&D agents in order to respond to the challenges identified in the thematic priorities.

Innovative and flexible energy harvesting and storage solutions are essential to fulfill the requirements of autonomous Wireless Sensor Nodes for the future Internet of Things, which is considered one of the five technologies that will change the world by connecting trillions of devices by 2030. The 3DSTORE project aims to power IoT nodes for critical infrastructure monitoring using next generation rechargeable All-Solid-State Batteries digitally manufactured by 3D printing. These are intrinsically safe due to the use of solid-state electrolytes, which replace highly flammable and toxic liquid electrolytes, while substantially minimize the content of some critical materials (Co and Li). Moreover, 3DSTORE monolithic battery concept will provide high energy densities very well aligned with performance objectives of the EU Strategic Research Agenda on Batteries and the Battery 2030+ roadmap.

The project has a total budget of 1.2M€ and will run for 3 years. Albert Tarancón, Prof. ICREA and Head of the Nanoionics and Fuel Cells group at IREC, leads this project. The KoM was held in Barcelona on February the 7th, 2023.

The 3DSTORE project addresses these challenging objectives by building an interdisciplinary consortium that includes some of the most relevant research partners in the field of batteries (CIC energiGUNE, IREC), 3D printing of advanced ceramics (Universidad de Castilla-La Mancha, IREC), IoT (Universitat Oberta de Catalunya), and a steel manufacturer (CELSA Group).

Beyond the coordination, the role of IREC in this project is to develop 3D printed batteries based on ceramic oxides using stereolithography. Apart from mastering the shaping of advanced geometries for better fitting IoT real scenarios and increasing the power of the devices, IREC will use 3D printing to develop hierarchical anode-electrolyte interfaces to fabricate robust anode-less batteries.
