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, mu ch attention has been paid to the battery application as effective use of c arbon materials that are made of various wastes. Then, we have investigated the electrochemical properties of the fly ash, which is one of the industr y wastes and naturally has macroporous structure. Besides, to control porou s structure artificially, we have applied the periodic porous nanostructure d carbon to electrodes, and found out a relatively high density rechargeabl e battery can be produced.
