- Inverse opal carbon materials were used as
anodes for lithium ion batteries. We applied particulate inverse
opal structures and their dispersion in the formation of anode
electrodes via solution casting. We prepared aminophenylgrafted
inverse opal carbons (a-IOC), inverse opal carbons
with mesopores (mIOC), and bare inverse opal carbons (IOC)
and investigated the electrochemical behavior of these samples
as anode materials. Surface modification by aminophenyl
groups was confirmed by XPS measurements. TEM images
showed mesopores, and the specific area of mIOC was
compared with that of IOC using BET analysis. A half-cell test was performed to compare a-IOC with IOC and mIOC with IOC.
In the case of the a-IOC structure, the cell test revealed no improvement in the reversible specific capacity or the cycle
performance. The mIOC cell showed a reversible specific capacity of 432 mAh/g, and the capacity was maintained at 88%-
approximately 380 mAh/g-over 20 cycles.
