High-energy-density on-chip zinc-air batteries

Project description

Powering a big solution for microbatteries

In recent years, advances in technology have enabled the development and manufacturing of smart dust, minuscule autonomous devices that can sense, process and transmit data, providing big data, medicine, artificial intelligence and other sectors with a revolutionary tool. Unfortunately, the lack of existing power sources with desirable energy density and footprint has greatly limited their application. Supported by the Marie Skłodowska-Curie Actions programme, the ChipZnAirB project will develop an innovative microbattery technology based on zinc-air interactions. To achieve this, it will develop a micro-origami self-assembly methodology that enhances volumetric energy density while retaining a compact footprint. Furthermore, the use of an air cathode will eliminate the need for onboard material storage, increasing energy efficiency.

Objective

The advent of smart dust, minuscule autonomous devices capable of sensing, processing, and transmitting data, has opened new frontiers in medicine, artificial intelligence (AI), and big data. However, their operation is significantly constrained by the limitations of existing power sources, particularly in terms of energy density and footprint, as was highlighted by the host [Nature, 2021, 589, 195]. This research proposal aims to address these challenges by developing a novel microbattery technology based on zinc-air chemistry. We propose a micro-origami approach to fabricate high-capacity, dust-sized zinc-air microbatteries. This method involves folding large-area thin films into three-dimensional (3D) structures by a micro-origami self-assembly method, significantly enhancing volumetric energy density while maintaining a compact footprint. By leveraging the abundant oxygen in the environment, the air cathode eliminates the need for onboard material storage, further improving energy efficiency. The core goal is to develop an on-chip microbattery with a footprint capacity exceeding 5 mAh/cm2 and a size under 1 mm2. To overcome the inherent challenges associated with zinc-air batteries, such as corrosion, bubble formation, and three-phase interface construction, we will combine detailed mechanism study with realistic numerical model to optimize electrode wettability, electrolyte composition, and cell configuration. Additionally, we will explore the integration of these microbatteries with various smart dust microsystems for demonstration. By achieving these goals, we can provide a reliable and high-performance power source for a wide range of smart dust applications, including environmental and agriculture monitoring, healthcare, and industrial automation. The successful development of this novel microbattery will have a profound impact on the field of microsystems and pave the way for the realization of advanced intelligent devices with unprecedented capabilities.
