Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Area of Science:

Materials Science
Electrochemistry
Energy Storage

Background:

Textile-based lithium-ion batteries (LIBs) are crucial for powering wearable electronics.
A significant safety concern for LIBs is thermal runaway induced by mechanical abuse.
Existing LIBs lack sufficient impact tolerance, posing risks during physical stress.

Purpose of the Study:

To develop highly impact-tolerant textile LIBs for enhanced safety in wearable applications.
To achieve electrochemical performance comparable to conventional metal-foil-based LIBs.
To investigate novel materials and configurations for robust energy storage solutions.

Main Methods:

Fabrication of LIBs using Kevlar fabric as the electrode material.
Integration of impact-tolerant shear thickening electrolytes (STEs) with Kevlar electrodes.
Mimicking the structure of liquid body armor using shear thickening fluids and Kevlar fabric.

Main Results:

Kevlar-fabric-based LIBs demonstrated high impact tolerance.
Electrochemical performance was comparable to traditional metal-foil-based cells.
The shear thickening effect and yarn-to-yarn friction within Kevlar dissipated impact energy.

Conclusions:

The developed Kevlar-fabric-based LIBs offer a promising solution for safe wearable electronics.
The integration of Kevlar and STEs effectively mitigates risks associated with mechanical abuse.
This approach provides a viable alternative for creating highly impact-tolerant LIBs.
