Fiber-shaped energy harvesting and storage devices pdf

What are fibre-based energy harvesting and storage devices?

In this Review, the development of fibre-based energy harvesting and storage devices is presented, focusing on dye-sensitized solar cells, lithium-ion batteries, supercapacitors and their integrated devices. An emphasis is placed on the interface between the active materials and the electrodes or electrolyte in the 1D devices.

How can energy harvesting and storage devices be integrated?

The integration of energy harvesting and storage devices is generally realized by coating in turn photovoltaic and electrochemically active materials on a fibre electrode or sequentially depositing them from inside out 29, 30.

Which energy harvesting and storage devices are not suitable for wearable electronics?

In particular, conventional energy harvesting and storage devices, including silicon-based solar cells, dielectric capacitors, lead–acid and lithium-ion batteries, fail to meet the flexibility required for wearable electronics 5.

What are textile-based energy storage devices?

The reported textile-based energy storage devices include supercapacitors (SCs) , flexible lithium-on batteries , Li–S batteries , Li–air batteries , sodium-ion batteries , Zn-ion batteries and silver–zinc batteries .

What are the developments in 1D energy harvesting and storage?

Figure 2: Timeline of developments in 1D energy harvesting and storage. Energy harvesting devices include solar cells and nanogenerators, and energy storage devices include supercapacitors and batteries.

How do energy harvesting and storage devices evolve from 3D to 1d?
