Biot-Savart Law: Problem-Solving

Biot-Savart Law: Problem-Solving

The magnitude and direction of a magnetic field created by a steady current can be calculated using the Biot-Savart law.
Consider a mobile phone battery bank as a source of steady current, which flows through the wire connected between the two. What is the magnitude of the magnetic field created by this current at a field point P?
To estimate the magnitude of the total magnetic field, we first consider a small current element of length dl, at a distance r from the field point. Now the following...

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...

To establish a design principle for flexible energy storage.

Main Methods:

Inspired by molecular structures, a snake-origami design integrating rigid (energy) and soft (deformation) segments was employed.
Fabrication of bidirectional flexible LIBs.
Performance evaluation including energy density and deformation capabilities.

Main Results:

A record-setting energy density of 357 Wh L⁻¹ (133 Wh kg⁻¹) was achieved.
The flexible snake-origami battery demonstrated favorable flexibility for arbitrary deformation.
A design principle for rigid-soft-coupled structures was established and validated.

Conclusions:

The novel bidirectional flexible snake-origami LIBs offer a promising solution for high-energy flexible power sources.
