"chemically bonded highly conductive single-walled carbon nanotubes with processable/ inexpensive polyaniline... stable even after >100K cycles, durable even in high-voltage environments, fast charging, improved range/ performance, can be rolled/ folded... mass produced fiber bundles, specific capacitance maintained without decreasing (PANI acts as nanocell inside)... forms liquid crystal phase based on carbon nanotubes, spinning it into coagulation bath, solidifying, stretching... EV's, drones, robots, wearables"
