Nanoarchitectonics of Lotus Seed Derived Nanoporous Carbon Materials for Supercapacitor Applications.

摘要: Of the available environmentally friendly energy storage devices, supercapacitors are most promising because of their high density, ultra-fast charging-discharging rate, outstanding cycle life, cost-effectiveness, and safety. In this work, nanoporous carbon materials were prepared by applying zinc chloride activation lotus seed powder from 600 °C to 1000 electrochemical (supercapacitance) resulting in aqueous electrolyte (1M H2SO4) reported. Lotus seed-derived activated display hierarchically porous structures comprised micropore mesopore architectures, exhibited excellent supercapacitance performances. The specific surface areas pore volumes found ranges 1103.0–1316.7 m2 g−1 0.741–0.887 cm3 g−1, respectively. capacitance optimum sample was ca. 317.5 F at 5 mV s−1 272.9 1 A accompanied retention 70.49% a potential sweep rate 500 s−1. electrode also showed good capability 52.1% upon increasing current density 50 with exceptional cyclic stability 99.2% after 10,000 cycles demonstrating prospects for agricultural waste stuffs, such as seed, production performance required supercapacitor applications.
