"10 m2 of fiber battery-based woven textiles. These textiles were specifically designed to be used to create smart and responsive tents and the fiber battery used to power them had an energy density of 550mWhm-2... can yield a remarkable 1,500 km of continuous fiber batteries for each individual spinneret unit used. This is over three times more batteries than those produced by the best performing echniques... remarkable production rates of 250 m h-1"
