The Future Wearable Battery Pack Lies In Yarn

Combined with solar cells, a “capacitive yarn” developed by US-based private research institution Drexel University and the US Naval Academy, could become the next wearable energy pack.

The yarn is produced by “natural fibre welding” of activated carbon-impregnated cotton fibre and stainless steel yarn. First, natural yarn is bathed in molten salt which makes it swell. Activated carbon particles are then infused into the yarn before it is washed with water, returning it to its original shape.

The steel allows the fibre to conduct electricity and makes it a storehouse of energy. Currently, the energy storage textile has applications in the US Navy as a wearable battery pack as well as the US Marine Corps. Researchers hint that this development could hit the fashion industry too.

If you want to know more about this and other topics directly from end users of energy storage technologies join us at one of these annual events: The Energy Storage World Forum (Grid Scale Applications), or The Residential Energy Storage Forum, or one of our Training Courses.


Battery Storage for Commercial & Industry

Powerful battery storage offers many advantages in terms of saving electricity costs and a reliable power supply. With this technology, companies retain control of their energy supply and costs. The battery storage system is charged when energy is cheaply available and it supplies the stored electricity when prices are at their highest. With applications such…
