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.
Claims34
A battery device comprising:
- a cathode current collector defining a first surface of the battery device;
- a fibrous cathode forming a structure defining a plurality of pores, a first portion of the fibrous cathode being in contact with the cathode current collector;
- an electrolytic polymer electrodeposited on the fibrous cathode to provide substantial uniform coverage of fibers forming the fibrous cathode;
- a plurality of anode particles disposed within the plurality of pores and separated from the fibrous cathode by the electrolytic polymer;
- and
- an anode current collector defining a second surface of the battery device.
A battery device comprising:
- an anode current collector defining a first surface of the battery device;
- a fibrous anode forming a structure defining a plurality of pores, a first portion of the fibrous anode being in contact with the anode current collector;
- an electrolytic polymer electrodeposited on the fibrous anode to provide substantial uniform coverage of fibers forming the fibrous anode;
- cathode particulates disposed within the plurality of pores and separated from the fibrous anode by the electrolytic polymer;
- and
- a cathode current collector defining a second surface of the battery device.
A method of forming a battery structure, the method comprising:
- applying an adhesive to a first current collector;
- electrospinning fibers onto the adhesive to form a mesh having fused fibers and a plurality of pores;
- electrodepositing a polymer onto the mesh to provide a coating on the exterior surface of the fused fibers;
- and
- infiltrating electrode particulates into the plurality of pores, the coating on the exterior surface of the fused fibers preventing direct contact between the electrode particulates and the fused fibers.
