Morphology, Conductivity and Electrochemical Properties of Hydrothermal Carbonized Porous Carbon Materials
Journal Title: Journal of Vasyl Stefanyk Precarpathian National University - Year 2016, Vol 3, Issue 1
Abstract
The paper studies the morphology, conductivity and electrochemical properties of carbon materials, obtained from raw plant materials at different condition of hydrothermal carbonization, using low-temperature porometry, impedance spectroscopy and galvanostatic charge/discharge. It is set, that in porous structure of carbon materials micropores are dominant; when carbonization temperature increased the specific surface and pore volume decrease more than 10 times. The temperature growth results in increasing the electrical conductivity of the carbon material more than 6 orders. It is found, that the maximal value of specific capacity (1138 mА·h/g) has an electrochemical system based on porous carbon carbonized at 1023 K.
