Claim 12:
13. A method for fabricating an electrochemical system, comprising:
forming a carbonaceous film;
forming a carbonaceous framework from the carbonaceous film comprising a three-dimensional interconnected corrugated carbon-based network (ICCN) comprising a plurality of expanded and interconnected carbon layers;
patterning the carbonaceous framework to form an array of two or more cells in one step, wherein the array of two or more cells comprises three or more first electrodes, each first electrode comprising three or more first microelectrodes, and three or more second electrodes, each second electrode comprising three or more second microelectrodes, wherein each first microelectrode is interdigitated with one second microelectrode to form one electrochemical cell; and
electrodepositing a pseudocapacitive material onto the three or more first electrodes, the three or more second electrodes, or both.
forming a charge storing active material comprising the three-dimensional ICCN having a plurality of pores from the carbonaceous film;
patterning the three-dimensional ICCN to form the array of two or more cells, wherein each cell comprises at least two electrodes; and
electrodepositing pseudocapacitive nanostructures within at least a portion of the plurality of pores, wherein the pseudocapacitive nanostructures comprise ultrathin nanoflakes up to 20 nm thick.
