Title: Three dimensional battery

Abstract: A battery device includes a cathode current collector and an anode current collector. A fibrous electrode forms a structure defining a plurality of pores. A first portion of the fibrous electrode is in contact with a current collector. An electrolytic polymer is electrodeposited on the fibrous electrode to provide substantial uniform coverage of fibers forming the fibrous electrode. A plurality of electrode particles are disposed within the plurality of pores and separated from the fibrous electrode by the electrolytic polymer.
