3D batt - Materials for 3D Battery Structures (completed)

Lithium ion batteries have high energy densities and are therefore widely used in powering portable electronics. The use of lithium ion batteries in large-scale applications such as hybrid electric vahicles, load leveling, and energy storage is lhnited by safety issues as well as their lifetime. The safety of lithium ion batteries can be improved by using solid-state electrolytes instead of liquid electrolytes. All-solid-state batteries have also improved lifetimes. The power density of lithium ion batteries can be increased by making the structures threedimensional (313).

About the project

In this project we will develop an all-solid -state 3D thin film lithium ion battery made by atomic layer deposition (ALD). ALD gives films with excellent conformality and uniformity and is therefore regarded as one of the best techniques to deposit films into 3D structures.

Initial testing of the batteries will be done on planar structures . The 3D batteries will be made to 3D structures developed in collaboration with Sintef Information and Communication Technology (ICT). Battery safety testing will be done in collaboration with Norwegian Defence Research Establishment (FFI) and scale-up in collaboration with Baldur Coating AS. 

Objectives

The primary objective is to make an all-ALD all-solid-state 31) thin film lithium ion battery. This includes developing an atomic layer deposition (ALD) process for the cathode and the anode materials state , finding a solid- electrolyte material that can be integrated into the system and developing a stable barrier layer between the solid-state electrolyte and the anode.

Financing

The project is financed by the Research Council of Norway.
