Organic Batteries: An Ultrahigh Output Rechargeable Electrode of a Hydrophilic Radical Polymer/Nanocarbon Hybrid with an Exceptionally Large Current Density beyond 1 A cm⁻² (Adv. Mater. 26/2018)

In article number 1800900, Kenichi Oyaizu, Hiroyuki Nishide, and co-workers achieve an ultrahigh discharge current density in organic batteries of over 1 A cm−2 by hybridizing a hydrophilic radical polymer and single-walled carbon nanotubes. The facile and long-range charge transport by the continuous polymer/nanotube network contribute to the large flux. A flexible, thin, and safe rechargeable device is fabricated using the polymer hybrids and brine as an electrolyte.
