Nanostructure-controlled Materials for Electrochemical Charging–Discharging

Abstract

Down-sizing of Li-host materials is one of the recent research trends to develop high-performance electrode materials. Nanosized materials are expected to show high rate capability and/or high capacities. Nanoporous materials are also candidates for high-performance electrode materials. This review introduces recent studies on nanosized and nanoporous electrode materials toward developing high-performance energy-storage devices.

Extraordinary Capacitance and Stability of Carbon Electrode for Electrochemical Capacitors

“…Porous carbon materials with high specific surface areas have been used as EDLC electrodes. 20 In aqueous electrolytes, oxygencontaining functional groups (OGCFs) at the pore entrance affect the access of electrolyte ions to the pores. Here, the group of the author (K.U.)…”

Creation of Mesopores in ZSM-5 Zeolite Crystals by a Novel Double-acyloxy Organosilane Surfactant

“…1 Many of them were found as natural minerals previously, but they are now the synthetic materials which are among the most widely used sorbents, catalysts and ionexchange materials. [2][3][4] By far, 191 structure types of zeolites have been known, with various Si/Al ratios, different pore diameters, pore shapes and connectivity. 5 Zeolites, with strong acidity and high specific surface area, are widely used as shapeselective catalysts in petrochemical industry, organic synthesis and adsorbents for organic compounds.…”
