posted on 2016-10-05, 00:00 authored by Jeong-Hyun Lee, Seung-Hwan LeeThe hybrid supercapacitor
using carbon/AlPO4 hybrid-coated H2Ti12O25/activated carbon is fabricated as a cylindrical cell
and investigated against electrochemical performances. The hybrid
coating shows that the conductivity for the electron and Li ion is
superior and it prevented active material from HF attack. Consequently,
carbon/AlPO4 hybrid-coated H2Ti12O25 shows enhanced rate capability and long-term cycle
life. Also, the hybrid coating inhibits swelling phenomenon caused
by gas generated as decomposition reaction of electrolyte. Therefore,
the hybrid supercapacitor using carbon/AlPO4 hybrid-coated
H2Ti12O25/activated carbon can be
applied to an energy storage system that requires a long-term life.
