Electrochemical properties of macroporous carbon for electrodes of lithium-ion batteries

Surface morphology of carbon-based electrodes affects capacities of lithium-ion batteries. While, from the viewpoints of recycle of various wastes, much attention has been paid to the battery application as effective use of carbon materials that are made of various wastes. Then, we have investigated the electrochemical properties of the fly ash, which is one of the industry wastes and naturally has macroporous structure. Besides, to control porous structure artificially, we have applied the periodic porous nanostructured carbon to electrodes, and found out a relatively high density rechargeable battery can be produced.
