First Claim
1. A vehicle body panel comprising:
- a metal inside surface;
a lithium-ion battery directly attached to the metal inside surface and including;
a first anode layer including a conductive bulk fiber and an anode active material;
a first non-conductive, porous layer contacting the first anode layer;
a first cathode layer including a conductive bulk fiber and a cathode active material contacting the first non-conductive, porous layer; and
a second non-conductive, porous layer contacting the first cathode layer;
wherein each of the first anode and cathode layers includes a body and a collector tab extending from the body, the collector tab including a conductive bulk fiber.

Abstract
Methods of forming a lithium-ion battery on a vehicle component by spinning and vehicle components with a batteries formed thereon are disclosed. The spinning may include electrospinning. A first electrode layer may be spun, followed by a first separator layer, a second electrode layer, and a second separator layer. Each layer may be spun directly onto the previously spun layer to provide a battery that does not include metal current collectors. The anode and/or cathode layers may include polyacrylonitrile (PAN) fibers. To render the anode and cathode layers conductive, they may be carbonized using a heat source (e.g., a laser). The disclosed method may allow for the formation of batteries directly onto a vehicle component, such as a body panel, thereby using otherwise empty space to increase the battery capacity of the vehicle.
