LiThium-iOn battery 3D Printing via Gel deposition and material extrUsioN (TOP GUN)
Abstract
The goal of the project is to investigate additive manufacturing, also known as 3D printing, as an innovative strategy to develop shape-conformable and structural batteries with dual functionality (electrochemical and mechanical). The use of additive manufacturing can provide tailored lithium-ion battery components with unique geometries, resulting in an enhancement of the electrodes surface area, ion diffusion, and, therefore, improved energy storage capability. The objective of the proposed work will be to 3D print a complete electrochemical cell with high energy density that does not require any additional post-processing steps such as debinding, sintering, or electrolyte filling, and that is capable of cycling in a wide range of temperature. The project aims to pursue the research in fundamental and applied science critical to the manufacture and electrochemical functionality of 3D all-solid-state batteries, which can be designed for a wide range of applications including, but not limited to, portable consumer electronics, automotive, naval, aerospace, defense, and biomedical fields. In this project, an original approach is proposed consisting of using a process for depositing materials, gel or paste, with infrared polymerization. The main advantages of using an IR source are that it is possible to polymerize thicker layers and more highly charged materials, and that the IR wavelength is safer for the user.
