1D Nanowire Electrode Materials for Power Sources of Microelectronics

Manipulation of nanostructured electrode material can provide versatile strategies toward improving the electrochemical properties. The nanostructure promotes fast Li-ion pathways for lithium ion transport and electronic conduction. Better rate capabilities are due to that the distance over which Li⁺ must diffuse in the solid state dramatically decreases in the nanostructured electrode. Recently, there are growing applications of these materials in the area of micro-potable electronics, such as micro-robots, sensor nods, active radio frequency identification (RF-ID) tag, etc. Fast charging time and longer may be essential for these applications, and 1D-nanowire materials may enable to realize much more faster charging speeds than those achieved using conventional bulk materials, without significant degradation in storage capacity.
